# Cohorting in 3rd Party Tools
Source: https://superwall.com/docs/ios/guides/3rd-party-analytics/cohorting-in-3rd-party-tools
To easily view Superwall cohorts in 3rd party tools, we recommend you set user attributes based on the experiments that users are included in. You can also use custom placements for creating analytics events for actions such as interacting with an element on a paywall.
:::ios
```swift Swift
extension SuperwallService: SuperwallDelegate {
func handleSuperwallEvent(withInfo eventInfo: SuperwallEventInfo) {
if eventInfo.event.description == "trigger_fire" {
MyAnalyticsService.shared.setUserAttributes([
"sw_experiment_\(eventInfo.event.params["experiment_id"])": true,
"sw_variant_\(eventInfo.event.params["variant_id"])": true
])
}
}
}
```
:::
Once you've set this up, you can easily ask for all users who have an attribute `sw_experiment_1234` and breakdown by both variants to see how users in a Superwall experiment behave in other areas of your app.

# Custom Paywall Analytics
Source: https://superwall.com/docs/ios/guides/3rd-party-analytics/custom-paywall-analytics
Learn how to log events from paywalls, such as a button tap or product change, to forward to your analytics service.
You can create customized analytics tracking for any paywall event by using custom placements. With them, you can get callbacks for actions such as interacting with an element on a paywall sent to your [Superwall delegate](/using-superwall-delegate). This can be useful for tracking how users interact with your paywall and how that affects their behavior in other areas of your app.
For example, in the paywall below, perhaps you're interested in tracking when people switch the plan from "Standard" and "Pro":

You could create a custom placement [tap behavior](/paywall-editor-styling-elements#tap-behaviors) which fires when a segment is tapped:

Then, you can listen for this placement and forward it to your analytics service:
```swift Swift
extension SuperwallService: SuperwallDelegate {
func handleSuperwallEvent(withInfo eventInfo: SuperwallEventInfo) {
switch eventInfo.event {
case let .customPlacement(name, params, paywallInfo):
// Prints out didTapPro or didTapStandard
print("\(name) - \(params) - \(paywallInfo)")
MyAnalyticsService.shared.send(event: name, params: params)
default:
print("Default event: \(eventInfo.event.description)")
}
}
}
```

### Hooking up Superwall events to 3rd party tools
SuperwallKit automatically tracks some internal events. You can [view the list of events here](/tracking-analytics). We encourage you to also track them in your own analytics by implementing the [Superwall delegate](/using-superwall-delegate). Using the `handleSuperwallEvent(withInfo:)` function, you can forward events to your analytics service:
:::ios
```swift Swift
extension SuperwallService: SuperwallDelegate {
func handleSuperwallEvent(withInfo eventInfo: SuperwallEventInfo) {
print("analytics event called", eventInfo.event.description)
MyAnalyticsService.shared.track(
event: eventInfo.event.description,
params: eventInfo.params
)
}
}
```
```swift Objective-C
- (void)handleSuperwallEventWithInfo:(SWKSuperwallEventInfo *)info {
NSLog(@"Analytics event called %@", info.event.description));
[[MyAnalyticsService shared] trackEvent:info.event.description params:info.params];
}
```
:::
You might also want to set user attribute to allow for [Cohorting in 3rd Party
Tools](/cohorting-in-3rd-party-tools)
Alternatively, if you want typed versions of all these events with associated values, you can access them via `eventInfo.event`:
:::ios
```swift
func handleSuperwallEvent(withInfo eventInfo: SuperwallEventInfo) {
switch eventInfo.event {
case .firstSeen:
break
case .appOpen:
break
case .appLaunch:
break

# Superwall Events
Source: https://superwall.com/docs/ios/guides/3rd-party-analytics/tracking-analytics
The SDK automatically tracks some events, which power the charts in the dashboard.
We encourage you to track them in your own analytics as described in [3rd Party Analytics](/3rd-party-analytics).
The following Superwall events can be used as placements to present paywalls:
* `app_install`
* `app_launch`
* `deepLink_open`
* `session_start`
* `paywall_decline`
* `transaction_fail`
* `transaction_abandon`
* `survey_response`

# Custom Paywall Actions
Source: https://superwall.com/docs/ios/guides/advanced/custom-paywall-actions
undefined
For example, adding a custom action called `help_center` to a button in your paywall gives you the opportunity to present a help center whenever that button is pressed. To set this up, implement `handleCustomPaywallAction(withName:)` in your `SuperwallDelegate`:
:::ios
```swift Swift
func handleCustomPaywallAction(withName name: String) {
if name == "help_center" {
HelpCenterManager.present()
}
}
```
```swift Objective-C
- (void)handleCustomPaywallActionWithName:(NSString *)name {
if ([name isEqualToString:"help_center"]) {
[HelpCenterManager present];
}
}
```
:::
Remember to set `Superwall.shared.delegate`! For implementation details, see the [Superwall Delegate](/using-superwall-delegate) guide.

# Purchasing Products Outside of a Paywall
Source: https://superwall.com/docs/ios/guides/advanced/direct-purchasing
undefined
If you're using Superwall for revenue tracking, but want a hand with making purchases in your implementation, you can use our `purchase` methods:
:::ios
```swift iOS
// For StoreKit 1
private func purchase(_ product: SKProduct) async throws -> PurchaseResult {
return await Superwall.shared.purchase(product)
}
// For StoreKit 2
private func purchase(_ product: StoreKit.Product) async throws -> PurchaseResult {
return await Superwall.shared.purchase(product)
}
// Superwall's `StoreProduct`
private func purchase(_ product: StoreProduct) async throws -> PurchaseResult {
return await Superwall.shared.purchase(product)
}
```
:::
For iOS, the `purchase()` method supports StoreKit 1, 2 and Superwall's abstraction over a product, `StoreProduct`. You can fetch the products you've added to Superwall via the `products(for:)` method. Similarly, in Android, you can fetch a product using a product identifier — and the first base plan will be selected:
:::ios
```swift iOS
private func fetchProducts(for identifiers: Set) async -> Set {
return await Superwall.shared.products(for: identifiers)
}
```
:::
If you already have your own product fetching code, simply pass the product representation to these methods. For example, in StoreKit 1 — an `SKProduct` instance, in StoreKit 2, `Product`, etc. Each `purchase()` implementation returns a `PurchaseResult`, which informs you of the transaction's resolution:
* `.cancelled`: The purchase was cancelled.
* `.purchased`: The product was purchased.
* `.pending`: The purchase is pending/deferred and requires action from the developer.
* `.failed(Error)`: The purchase failed for a reason other than the user cancelling or the payment pending.

# Game Controller Support
Source: https://superwall.com/docs/ios/guides/advanced/game-controller-support
undefined
:::ios
First, set the `SuperwallOption` `isGameControllerEnabled` to `true`:
```swift
let options = SuperwallOptions()
options.isGameControllerEnabled = true
Superwall.configure(apiKey: "MY_API_KEY", options: options);
```
Forward events to your paywall by calling `gamepadValueChanged(gamepad:element:)` from your own gamepad's `valueChanged` handler:
```swift
controller.extendedGamepad?.valueChangedHandler = { gamepad, element in
// send values to Superwall
Superwall.shared.gamepadValueChanged(gamepad: gamepad, element: element)
// ... rest of your code
}
```
:::
---
# Observer Mode
Source: https://superwall.com/docs/ios/guides/advanced/observer-mode
undefined
If you wish to make purchases outside of Superwall's SDK and paywalls, you can use **observer mode** to report purchases that will appear in the Superwall dashboard, such as transactions:

This is useful if you are using Superwall solely for revenue tracking, and you're making purchases using frameworks like StoreKit or Google Play Billing Library directly. Observer mode will also properly link user identifiers to transactions. To enable observer mode, set it using `SuperwallOptions` when configuring the SDK:
:::ios
```swift iOS
let options = SuperwallOptions()
options.shouldObservePurchases = true
Superwall.configure(apiKey: "your_api_key", options: options)
```
:::
There are a few things to keep in mind when using observer mode:
1. On iOS, if you're using StoreKit 2, then Superwall solely reports transaction completions. If you're using StoreKit 1, then Superwall will report transaction starts, abandons, and completions.
2. When using observer mode, you can't make purchases using our SDK — such as `Superwall.shared.purchase(aProduct)`.

# Retrieving and Presenting a Paywall Yourself
Source: https://superwall.com/docs/ios/guides/advanced/presenting-paywalls
undefined
If you want complete control over the paywall presentation process, you can use `getPaywall(forPlacement:params:paywallOverrides:delegate:)`. This returns the `UIViewController` subclass `PaywallViewController`, which you can then present however you like. Or, you can use a SwiftUI `View` via `PaywallView`. The following is code is how you'd mimic [register](/docs/feature-gating):
```swift Swift
final class MyViewController: UIViewController {
private func presentPaywall() async {
do {
// 1
let paywallVc = try await Superwall.shared.getPaywall(
forPlacement: "campaign_trigger",
delegate: self
)
self.present(paywallVc, animated: true)
} catch let skippedReason as PaywallSkippedReason {
// 2
switch skippedReason {
case .holdout,
.noAudienceMatch,
.placementNotFound:
break
}
} catch {
// 3
print(error)
}
}
private func launchFeature() {
// Insert code to launch a feature that's behind your paywall.
}
}

This does the following:
1. Gets the paywall view controller.
2. Handles the cases where the paywall was skipped.
3. Catches any presentation errors.
4. Implements the delegate. This is called when the user is finished with the paywall. First, it checks `shouldDismiss`. If this is true then is dismissed the paywall from view before launching any features. This may depend on the `result` depending on how you first presented your view. Then, it switches over the `result`. If the result is `purchased` or `restored` the feature can be launched. However, if the result is `declined`, it checks that the the `featureGating` property of `paywall.info` is `nonGated` and that the `closeReason` isn't `.forNextPaywall`.
### Best practices
1. **Make sure to prevent a paywall from being accessed after a purchase has occurred**.
If a user purchases from a paywall, it is your responsibility to make sure that the user can't access that paywall again. For example, if after successful purchase you decide to push a new view on to the navigation stack, you should make sure that the user can't go back to access the paywall.
2. **Make sure the paywall view controller deallocates before presenting it elsewhere**.
If you have a paywall view controller presented somewhere and you try to present
the same view controller elsewhere, you will get a crash. For example, you may
have a paywall in a tab bar controller, and then you also try to present it
modally. We plan on improving this, but currently it's your responsibility to
ensure this doesn't happen.
:::ios
3. **Listening for Loading State Changes**.
If you have logic that depends on the progress of the paywall's loading state, you can use the delegate function `paywall(_:loadingStateDidChange:)`. Or, if you have an instance of a `PaywallViewController`, you can use the published property:
```swift
let stateSub = paywall.$loadingState.sink { state in
print(state)
}
```

# Using the Presentation Handler
Source: https://superwall.com/docs/ios/guides/advanced/using-the-presentation-handler
undefined
You can provide a `PaywallPresentationHandler` to `register`, whose functions provide status updates for a paywall:
* `onDismiss`: Called when the paywall is dismissed. Accepts a `PaywallInfo` object containing info about the dismissed paywall, and there is a `PaywallResult` informing you of any transaction.
* `onPresent`: Called when the paywall did present. Accepts a `PaywallInfo` object containing info about the presented paywall.
* `onError`: Called when an error occurred when trying to present a paywall. Accepts an `Error` indicating why the paywall could not present.
* `onSkip`: Called when a paywall is skipped. Accepts a `PaywallSkippedReason` enum indicating why the paywall was skipped.
```swift Swift
let handler = PaywallPresentationHandler()
handler.onDismiss { paywallInfo, result in
print("The paywall dismissed. PaywallInfo: \(paywallInfo). Result: \(result)")
}
handler.onPresent { paywallInfo in
print("The paywall presented. PaywallInfo:", paywallInfo)
}
handler.onError { error in
print("The paywall presentation failed with error \(error)")
}
handler.onSkip { reason in
switch reason {
case .holdout(let experiment):
print("Paywall not shown because user is in a holdout group in Experiment: \(experiment.id)")
case .noAudienceMatch:
print("Paywall not shown because user doesn't match any audiences.")
case .placementNotFound:
print("Paywall not shown because this placement isn't part of a campaign.")
}
}
Superwall.shared.register(placement: "campaign_trigger", handler: handler) {
// Feature launched
}
```
```swift Objective-C

Wanting to see which product was just purchased from a paywall? Use `onDismiss` and the `result`
parameter. Or, you can use the
[SuperwallDelegate](/3rd-party-analytics#using-events-to-see-purchased-products).

# Viewing Purchased Products
Source: https://superwall.com/docs/ios/guides/advanced/viewing-purchased-products
undefined
When a paywall is presenting and a user converts, you can view the purchased products in several different ways.
### Use the `PaywallPresentationHandler`
Arguably the easiest of the options — simply pass in a presentation handler and check out the product within the `onDismiss` block.
```swift Swift
let handler = PaywallPresentationHandler()
handler.onDismiss { _, result in
switch result {
case .declined:
print("No purchased occurred.")
case .purchased(let product):
print("Purchased \(product.productIdentifier)")
case .restored:
print("Restored purchases.")
}
}
Superwall.shared.register(placement: "caffeineLogged", handler: handler) {
logCaffeine()
}
```
```swift Objective-C
SWKPaywallPresentationHandler *handler = [SWKPaywallPresentationHandler new];
[handler onDismiss:^(SWKPaywallInfo * _Nonnull info,
enum SWKPaywallResult result,
SWKStoreProduct * _Nullable product) {
switch (result) {
case SWKPaywallResultPurchased:
NSLog(@"Purchased %@", product.productIdentifier);
default:
NSLog(@"Unhandled event.");
}
}];
[[Superwall sharedInstance] registerWithPlacement:@"caffeineLogged"
params:@{}
handler:handler
feature:^{
[self logCaffeine];
}];
```
```kotlin Android
val handler = PaywallPresentationHandler()
handler.onDismiss { _, paywallResult ->
when (paywallResult) {
is PaywallResult.Purchased -> {
// The user made a purchase!
val purchasedProductId = paywallResult.productId
println("User purchased product: $purchasedProductId")
// ... do something with the purchased product ID ...
}
is PaywallResult.Declined -> {
// The user declined to make a purchase.
println("User declined to make a purchase.")
// ... handle the declined case ...
}
is PaywallResult.Restored -> {
// The user restored a purchase.
println("User restored a purchase.")
// ... handle the restored case ...
}
}
}
Superwall.instance.register(placement = "caffeineLogged", handler = handler) {
logCaffeine()
}
```
```dart Flutter
PaywallPresentationHandler handler = PaywallPresentationHandler();
handler.onDismiss((paywallInfo, paywallResult) async {
String name = await paywallInfo.name;
print("Handler (onDismiss): $name");
switch (paywallResult) {
case PurchasedPaywallResult(productId: var id):
// The user made a purchase!
print('User purchased product: $id');
// ... do something with the purchased product ID ...
break;
case DeclinedPaywallResult():
// The user declined to make a purchase.
print('User declined the paywall.');
// ... handle the declined case ...
break;
case RestoredPaywallResult():
// The user restored a purchase.
print('User restored a previous purchase.');
// ... handle the restored case ...
break;
}
});
Superwall.shared.registerPlacement(
"caffeineLogged", handler: handler, feature: () {
logCaffeine();
});
```
```typescript React Native
import * as React from "react"
import Superwall from "../../src"
import { PaywallPresentationHandler, PaywallInfo } from "../../src"
import type { PaywallResult } from "../../src/public/PaywallResult"
const Home = () => {
const navigation = useNavigation()
const presentationHandler: PaywallPresentationHandler = {
onDismiss: (handler: (info: PaywallInfo, result: PaywallResult) => void) => {
handler = (info, result) => {
console.log("Paywall dismissed with info:", info, "and result:", result)
if (result.type === "purchased") {
console.log("Product purchased with ID:", result.productId)
}
}
},
onPresent: (handler: (info: PaywallInfo) => void) => {
handler = (info) => {
console.log("Paywall presented with info:", info)
// Add logic for when the paywall is presented
}
},
onError: (handler: (error: string) => void) => {
handler = (error) => {
console.error("Error presenting paywall:", error)
// Handle any errors that occur during presentation
}
},
onSkip: () => {
console.log("Paywall presentation skipped")
// Handle the case where the paywall presentation is skipped
},
}
const nonGated = () => {
Superwall.shared.register({ placement: "non_gated", handler: presentationHandler, feature: () => {
navigation.navigate("caffeineLogged", {
value: "Go for caffeine logging",
})
});
}
return // Your view code here
}
```
### Use `SuperwallDelegate`
Next, the [SuperwallDelegate](/using-superwall-delegate) offers up much more information, and can inform you of virtually any Superwall event that occurred:
```swift Swift
class SWDelegate: SuperwallDelegate {
func handleSuperwallEvent(withInfo eventInfo: SuperwallEventInfo) {
switch eventInfo.event {
case .transactionComplete(_, let product, _, _):
print("Transaction complete: product: \(product.productIdentifier)")
case .subscriptionStart(let product, _):
print("Subscription start: product: \(product.productIdentifier)")
case .freeTrialStart(let product, _):
print("Free trial start: product: \(product.productIdentifier)")
case .transactionRestore(_, _):
print("Transaction restored")
case .nonRecurringProductPurchase(let product, _):
print("Consumable product purchased: \(product.id)")
default:
print("Unhandled event.")
}
}
}
@main
struct Caffeine_PalApp: App {
@State private var swDelegate: SWDelegate = .init()
init() {
Superwall.configure(apiKey: "my_api_key")
Superwall.shared.delegate = swDelegate
}
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
```
```swift Objective-C
// SWDelegate.h...
#import
@import SuperwallKit;
NS_ASSUME_NONNULL_BEGIN
@interface SWDelegate : NSObject
@end
NS_ASSUME_NONNULL_END
// SWDelegate.m...
@implementation SWDelegate
- (void)handleSuperwallEventWithInfo:(SWKSuperwallEventInfo *)eventInfo {
switch(eventInfo.event) {
case SWKSuperwallEventTransactionComplete:
NSLog(@"Transaction complete: %@", eventInfo.params[@"primary_product_id"]);
}
}
// In AppDelegate.m...
#import "AppDelegate.h"
#import "SWDelegate.h"
@import SuperwallKit;
@interface AppDelegate ()
@property (strong, nonatomic) SWDelegate *delegate;
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.delegate = [SWDelegate new];
[Superwall configureWithApiKey:@"my_api_key"];
[Superwall sharedInstance].delegate = self.delegate;
return YES;
}
```
```kotlin Android
class SWDelegate : SuperwallDelegate {
override fun handleSuperwallEvent(eventInfo: SuperwallEventInfo) {
when (eventInfo.event) {
is SuperwallPlacement.TransactionComplete -> {
val transaction = (eventInfo.event as SuperwallPlacement.TransactionComplete).transaction
val product = (eventInfo.event as SuperwallPlacement.TransactionComplete).product
val paywallInfo = (eventInfo.event as SuperwallPlacement.TransactionComplete).paywallInfo
println("Transaction Complete: $transaction, Product: $product, Paywall Info: $paywallInfo")
}
else -> {
// Handle other cases
}
}
}
}
class MyApplication : Application() {
override fun onCreate() {
super.onCreate()
Superwall.configure(this, "my_api_key")
Superwall.instance.delegate = SWDelegate()
}
}
```
```dart Flutter
import 'dart:io';
import 'package:flutter/material.dart';
import 'package:superwallkit_flutter/superwallkit_flutter.dart';
class _MyAppState extends State implements SuperwallDelegate {
final logging = Logging();
@override
void initState() {
super.initState();
configureSuperwall(useRevenueCat);
}
Future configureSuperwall(bool useRevenueCat) async {
try {
final apiKey = Platform.isIOS
? 'ios_api_project_key'
: 'android_api_project_key';
final logging = Logging();
logging.level = LogLevel.warn;
logging.scopes = {LogScope.all};
final options = SuperwallOptions();

switch (eventInfo.event.type) {
case PlacementType.transactionComplete:
final product = eventInfo.params?['product'];
logging.info('Transaction complete event received with product: $product');
// Add any additional logic you need to handle the transaction complete event
break;
// Handle other events if necessary
default:
logging.info('Unhandled event type: ${eventInfo.event.type}');
break;
}
}
}
```
```typescript React Native
import {
PaywallInfo,
SubscriptionStatus,
SuperwallDelegate,
SuperwallPlacementInfo,
PlacementType,
} from '../../src';
export class MySuperwallDelegate extends SuperwallDelegate {
handleSuperwallPlacement(placementInfo: SuperwallPlacementInfo) {
console.log('Handling Superwall placement:', placementInfo);
switch (placementInfo.placement.type) {
case PlacementType.transactionComplete:
const product = placementInfo.params?.["product"];
if (product) {
console.log(`Product: ${product}`);
} else {
console.log("Product not found in params.");
}
break;
default:
break;
}
}
}
export default function App() {
const delegate = new MySuperwallDelegate();
React.useEffect(() => {
const setupSuperwall = async () => {
const apiKey =
Platform.OS === 'ios'
? 'ios_api_project_key'
: 'android_api_project_key';
Superwall.configure({
apiKey: apiKey,
});
Superwall.shared.setDelegate(delegate);
};
}
}
```
### Use a purchase controller
If you are controlling the purchasing pipeline yourself via a [purchase controller](/advanced-configuration), then naturally the purchased product is available:
```swift Swift
final class MyPurchaseController: PurchaseController {
func purchase(product: StoreProduct) async -> PurchaseResult {
print("Kicking off purchase of \(product.productIdentifier)")
do {
let result = try await MyPurchaseLogic.purchase(product: product)
return .purchased // .cancelled, .pending, .failed(Error)
} catch {
return .failed(error)
}
}
// 2
func restorePurchases() async -> RestorationResult {
print("Restoring purchases")
return .restored // false
}
}
@main
struct Caffeine_PalApp: App {
private let pc: MyPurchaseController = .init()
init() {
Superwall.configure(apiKey: "my_api_key", purchaseController: pc)
}
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
```
```swift Objective-C
// In MyPurchaseController.h...
#import
@import SuperwallKit;
@import StoreKit;
NS_ASSUME_NONNULL_BEGIN
@interface MyPurchaseController : NSObject
+ (instancetype)sharedInstance;
@end
NS_ASSUME_NONNULL_END
// In MyPurchaseController.m...
#import "MyPurchaseController.h"
@implementation MyPurchaseController
+ (instancetype)sharedInstance
{
static MyPurchaseController *sharedInstance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedInstance = [MyPurchaseController new];
});
return sharedInstance;
}
- (void)purchaseWithProduct:(SWKStoreProduct * _Nonnull)product
completion:(void (^ _Nonnull)(enum SWKPurchaseResult, NSError * _Nullable))completion {
NSLog(@"Kicking off purchase of %@", product.productIdentifier);
// Do purchase logic here
completion(SWKPurchaseResultPurchased, nil);
}
- (void)restorePurchasesWithCompletion:(void (^ _Nonnull)(enum SWKRestorationResult, NSError * _Nullable))completion {
// Do restore logic here
completion(SWKRestorationResultRestored, nil);
}
@end
// In AppDelegate.m...
#import "AppDelegate.h"
#import "MyPurchaseController.h"
@import SuperwallKit;
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[Superwall configureWithApiKey:@"my_api_key"
purchaseController:[MyPurchaseController sharedInstance]
options:nil
completion:^{
}];
return YES;
}
```
```kotlin Android
class MyPurchaseController(val context: Context): PurchaseController {
override suspend fun purchase(
activity: Activity,
productDetails: ProductDetails,
basePlanId: String?,
offerId: String?
): PurchaseResult {
println("Kicking off purchase of $basePlanId")
return PurchaseResult.Purchased()
}
override suspend fun restorePurchases(): RestorationResult {
TODO("Not yet implemented")
}
}
class MyApplication : Application() {
override fun onCreate() {
super.onCreate()
Superwall.configure(this, "my_api_key", purchaseController = MyPurchaseController(this))
}
}
```
```dart Flutter
class MyPurchaseController extends PurchaseController {
// 1
@override
Future purchaseFromAppStore(String productId) async {
print('Attempting to purchase product with ID: $productId');
// Do purchase logic
return PurchaseResult.purchased;
}
@override
Future purchaseFromGooglePlay(
String productId,
String? basePlanId,
String? offerId
) async {
print('Attempting to purchase product with ID: $productId and basePlanId: $basePlanId');
// Do purchase logic
return PurchaseResult.purchased;
}
@override
Future restorePurchases() async {
// Do resture logic
}
}
```
```typescript React Native
export class MyPurchaseController extends PurchaseController {
// 1
async purchaseFromAppStore(productId: string): Promise {
console.log("Kicking off purchase of ", productId)
// Purchase logic
return await this._purchaseStoreProduct(storeProduct)
}
async purchaseFromGooglePlay(
productId: string,
basePlanId?: string,
offerId?: string
): Promise {
console.log("Kicking off purchase of ", productId, " base plan ID", basePlanId)
// Purchase logic
return await this._purchaseStoreProduct(storeProduct)
}
// 2
async restorePurchases(): Promise {
// TODO
// ----
// Restore purchases and return true if successful.
}
}
```
### SwiftUI - Use `PaywallView`
The `PaywallView` allows you to show a paywall by sending it a placement. It also has a dismiss handler where the purchased product will be vended:
```swift
@main
struct Caffeine_PalApp: App {
@State private var presentPaywall: Bool = false
init() {
Superwall.configure(apiKey: "my_api_key")
}
var body: some Scene {
WindowGroup {
Button("Log") {
presentPaywall.toggle()
}
.sheet(isPresented: $presentPaywall) {
PaywallView(placement: "caffeineLogged", params: nil, paywallOverrides: nil) { info, result in
switch result {
case .declined:
print("No purchased occurred.")
case .purchased(let product):
print("Purchased \(product.productIdentifier)")
case .restored:
print("Restored purchases.")
}
} feature: {
print("Converted")
presentPaywall.toggle()
}
}
}
}
}
```

# Advanced Purchasing
Source: https://superwall.com/docs/ios/guides/advanced-configuration
If you need fine-grain control over the purchasing pipeline, use a purchase controller to manually handle purchases and subscription status.
Using a `PurchaseController` is only recommended for **advanced** use cases. By default, Superwall handles all
subscription-related logic and purchasing operations for you out of the box.
By default, Superwall handles basic subscription-related logic for you:
1. **Purchasing**: When the user initiates a checkout on a paywall.
2. **Restoring**: When the user restores previously purchased products.
3. **Subscription Status**: When the user's subscription status changes to active or expired (by checking the local receipt).
However, if you want more control, you can pass in a `PurchaseController` when configuring the SDK via `configure(apiKey:purchaseController:options:)` and manually set `Superwall.shared.subscriptionStatus` to take over this responsibility.
### Step 1: Creating a `PurchaseController`
A `PurchaseController` handles purchasing and restoring via protocol methods that you implement.
:::ios
```swift Swift
// MyPurchaseController.swift
import SuperwallKit
import StoreKit
final class MyPurchaseController: PurchaseController {
static let shared = MyPurchaseController()
// 1
func purchase(product: StoreProduct) async -> PurchaseResult {
// Use StoreKit or some other SDK to purchase...
// Send Superwall the result.
return .purchased // .cancelled, .pending, .failed(Error)
}
func restorePurchases() async -> RestorationResult {
// Use StoreKit or some other SDK to restore...
// Send Superwall the result.
return .restored // Or failed(error)
}
}
```
```swift Objective-C
@import SuperwallKit;
@import StoreKit;
// MyPurchaseController
@interface MyPurchaseController: NSObject
+ (instancetype)sharedInstance;
@end
@implementation MyPurchaseController
+ (instancetype)sharedInstance
{
static MyPurchaseController *sharedInstance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedInstance = [MyPurchaseController new];
});
return sharedInstance;
}
// 1
- (void)purchaseWithProduct:(SWKStoreProduct * _Nonnull)product completion:(void (^ _Nonnull)(enum SWKPurchaseResult, NSError * _Nullable))completion {
// TODO
// ----
// Purchase via StoreKit, RevenueCat, Qonversion or however
// you like and return a valid SWKPurchaseResult
completion(SWKPurchaseResultPurchased, nil);
}
// 2
- (void)restorePurchasesWithCompletion:(void (^ _Nonnull)(enum SWKRestorationResult, NSError * _Nullable))completion {
// TODO
// ----
// Restore purchases and return `SWKRestorationResultRestored` if successful.
// Return an `NSError` if not.
completion(SWKRestorationResultRestored, nil);
}
@end
```
```swift
import StoreKit
import SuperwallKit
final class SWPurchaseController: PurchaseController {
// MARK: Sync Subscription Status
/// Makes sure that Superwall knows the customer's subscription status by
/// changing `Superwall.shared.subscriptionStatus`
func syncSubscriptionStatus() async {
var products: Set = []
for await verificationResult in Transaction.currentEntitlements {
switch verificationResult {
case .verified(let transaction):
products.insert(transaction.productID)
case .unverified:
break
}
}
let storeProducts = await Superwall.shared.products(for: products)
let entitlements = Set(storeProducts.flatMap { $0.entitlements })
await MainActor.run {
Superwall.shared.subscriptionStatus = .active(entitlements)
}
}
// MARK: Handle Purchases
/// Makes a purchase with Superwall and returns its result after syncing subscription status. This gets called when
/// someone tries to purchase a product on one of your paywalls.
func purchase(product: StoreProduct) async -> PurchaseResult {
let result = await Superwall.shared.purchase(product)
await syncSubscriptionStatus()
return result
}
// MARK: Handle Restores
/// Makes a restore with Superwall and returns its result after syncing subscription status.
/// This gets called when someone tries to restore purchases on one of your paywalls.
func restorePurchases() async -> RestorationResult {
let result = await Superwall.shared.restorePurchases()
await syncSubscriptionStatus()
return result
}
}
```
:::
Here’s what each method is responsible for:
1. Purchasing a given product. In here, enter your code that you use to purchase a product. Then, return the result of the purchase as a `PurchaseResult`. For Flutter, this is separated into purchasing from the App Store and Google Play. This is an enum that contains the following cases, all of which must be handled:
1. `.cancelled`: The purchase was cancelled.
2. `.purchased`: The product was purchased.
3. `.pending`: The purchase is pending/deferred and requires action from the developer.
4. `.failed(Error)`: The purchase failed for a reason other than the user cancelling or the payment pending.
2. Restoring purchases. Here, you restore purchases and return a `RestorationResult` indicating whether the restoration was successful or not. If it was, return `.restore`, or `failed` along with the error reason.
### Step 2: Configuring the SDK With Your `PurchaseController`
Pass your purchase controller to the `configure(apiKey:purchaseController:options:)` method:
:::ios
```swift UIKit
// AppDelegate.swift
import UIKit
import SuperwallKit
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
Superwall.configure(
apiKey: "MY_API_KEY",
purchaseController: MyPurchaseController.shared // <- Handle purchases on your own
)
return true
}
}
```
```swift SwiftUI
@main
struct MyApp: App {
init() {
Superwall.configure(
apiKey: "MY_API_KEY",
purchaseController: MyPurchaseController.shared // <- Handle purchases on your own
)
}
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
```
```swift Objective-C
// AppDelegate.m
@import SuperwallKit;
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[Superwall configureWithApiKey:@"MY_API_KEY" purchaseController:[MyPurchaseController sharedInstance] options:nil completion:nil];
return YES;
}
```
:::
### Step 3: Keeping `subscriptionStatus` Up-To-Date
You **must** set `Superwall.shared.subscriptionStatus` every time the user's subscription status changes, otherwise the SDK won't know who to show a paywall to. This is an enum that has three possible cases:
1. **`.unknown`**: This is the default value. In this state, paywalls will not show and their presentation will be ***automatically delayed*** until `subscriptionStatus` changes to a different value.
2. **`.active(let entitlements)`**: Indicates that the user has an active entitlement. Paywalls will not show in this state unless you remotely set the paywall to ignore subscription status. A user can have one or more active entitlement.
3. **`.inactive`**: Indicates that the user doesn't have an active entitlement. Paywalls can show in this state.
Here's how you might do this:
:::ios
```swift Swift
import SuperwallKit
func syncSubscriptionStatus() async {
var purchasedProductIds: Set = []
// get all purchased product ids
for await verificationResult in Transaction.currentEntitlements {
switch verificationResult {
case .verified(let transaction):
purchasedProductIds.insert(transaction.productID)
case .unverified:
break
}
}
// get store products for purchased product ids from Superwall
let storeProducts = await Superwall.shared.products(for: purchasedProductIds)
// get entitlements from purchased store products
let entitlements = Set(storeProducts.flatMap { $0.entitlements })
// set subscription status
await MainActor.run {
Superwall.shared.subscriptionStatus = .active(entitlements)
}
}
```
```swift Objective-C
@import SuperwallKit;
// when a subscription is purchased, restored, validated, expired, etc...
[myService setSubscriptionStatusDidChange:^{
if (user.hasActiveSubscription) {
[Superwall sharedInstance] setActiveSubscriptionStatusWith:[NSSet setWithArray:@[myEntitlements]]];
} else {
[[Superwall sharedInstance] setInactiveSubscriptionStatus];
}
}];
```
:::
`subscriptionStatus` is cached between app launches
### Listening for subscription status changes
If you need a simple way to observe when a user's subscription status changes, on iOS you can use the `Publisher` for it. Here's an example:
:::ios
```swift iOS
subscribedCancellable = Superwall.shared.$subscriptionStatus
.receive(on: DispatchQueue.main)
.sink { [weak self] status in
switch status {
case .unknown:
self?.subscriptionLabel.text = "Loading subscription status."
case .active(let entitlements):
self?.subscriptionLabel.text = "You currently have an active subscription: \(entitlements.map { $0.id }). Therefore, the paywall will not show unless feature gating is disabled."
case .inactive:
self?.subscriptionLabel.text = "You do not have an active subscription so the paywall will show when clicking the button."
}
}
```
:::
You can do similar tasks with the `SuperwallDelegate`, such as [viewing which product was purchased from a paywall](/3rd-party-analytics#using-events-to-see-purchased-products).

# App Store Privacy Labels
Source: https://superwall.com/docs/ios/guides/app-privacy-nutrition-labels
undefined
When submitting your app for review, you'll need to fill out an App Store Privacy label. When using the Superwall SDK, there are a few choices you may need to consider.
### App Store Privacy Labels
Privacy disclosures in regards to how data is processed or otherwise used are required when submitting an app for review on the App Store. When using the Superwall SDK, there are a few options you'll need to select to comply with this requirement.
**At a minimum, you'll need to select "Purchases":**

When you select "Purchases", you'll need to scroll down finish setup. When you do, there are two options you'll need to select:
1. Analytics
2. App Functionality

### Identifying Users
How you proceed with the next prompt depends on how you are identifying users. If you *are* identifying users via their email or any other means, disclose that here. Note that the Superwall SDK does not do this.
Finally, Superwall does not track purchase history of users for advertising purposes — so you can choose "No" here (unless you're using other SDKs which do this, or you're performing any purchase history tracking for advertising purposes on your own ):

In terms of the Superwall SDK, that's all you need to choose. But again, remember that your privacy label could look different depending on how you process data, how other SDKs are used and more.
### Collected Data

# Advanced Configuration
Source: https://superwall.com/docs/ios/guides/configuring
When configuring the SDK you can pass in options that configure Superwall, the paywall presentation, and its appearance.
### Logging
Logging is enabled by default in the SDK and is controlled by two properties: `level` and `scopes`.
`level` determines the minimum log level to print to the console. There are five types of log level:
1. **debug**: Prints all logs from the SDK to the console. Useful for debugging your app if something isn't working as expected.
2. **info**: Prints errors, warnings, and useful information from the SDK to the console.
3. **warn**: Prints errors and warnings from the SDK to the console.
4. **error**: Only prints errors from the SDK to the console.
5. **none**: Turns off all logs.
The SDK defaults to `info`.
`scopes` defines the scope of logs to print to the console. For example, you might only care about logs relating to `paywallPresentation` and `paywallTransactions`. This defaults to `.all`. Check out [LogScope](https://sdk.superwall.me/documentation/superwallkit/logscope) for all possible cases.
You set these properties like this:
:::ios
```swift Swift
let options = SuperwallOptions()
options.logging.level = .warn
options.logging.scopes = [.paywallPresentation, .paywallTransactions]
Superwall.configure(apiKey:"MY_API_KEY", options: options);
// Or you can set:
Superwall.shared.logLevel = .warn
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.logging.level = SWKLogLevelWarn;
[Superwall
configureWithApiKey:@"pk_e6bd9bd73182afb33e95ffdf997b9df74a45e1b5b46ed9c9"
purchaseController:nil
options:options
completion:nil
];
[Superwall sharedInstance].logLevel = SWKLogLevelWarn;
```
:::
### Preloading Paywalls
Paywalls are preloaded by default when the app is launched from a cold start. The paywalls that are preloaded are determined by the list of placements that result in a paywall for the user when [registered](/docs/feature-gating). Preloading is smart, only preloading paywalls that belong to audiences that could be matched.
Paywalls are cached by default, which means after they load once, they don't need to be reloaded from the network unless you make a change to them on the dashboard. However, if you have a lot of paywalls, preloading may increase network usage of your app on first load of the paywalls and result in slower loading times overall.
You can turn off preloading by setting `shouldPreload` to `false`:
:::ios
```swift Swift
let options = SuperwallOptions()
options.paywalls.shouldPreload = false
Superwall.configure(apiKey: "MY_API_KEY", options: options)
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.paywalls.shouldPreload = false;
[Superwall
configureWithApiKey:@"MY_API_KEY"
purchaseController:nil
options:options
completion:nil
];
```
:::
Then, if you'd like to preload paywalls for specific placements you can use `preloadPaywalls(forPlacements:)`:
:::ios
```swift Swift
Superwall.shared.preloadPaywalls(forPlacements: ["campaign_trigger"]);
```
```swift Objective-C
NSMutableSet *eventNames = [NSMutableSet set];
[eventNames addObject:@"campaign_trigger"];
[[Superwall sharedInstance] preloadPaywallsForPlacements:placementNames];
```
:::
If you'd like to preload all paywalls you can use `preloadAllPaywalls()`:
:::ios
```swift Swift
Superwall.shared.preloadAllPaywalls()
```
```swift Objective-C
[[Superwall sharedInstance] preloadAllPaywalls];
```
:::
Note: These methods will not reload any paywalls that have already been preloaded.
### External Data Collection
By default, Superwall sends all registered events and properties back to the Superwall servers. However, if you have privacy concerns, you can stop this by setting `isExternalDataCollectionEnabled` to `false`:
:::ios
```swift Swift
let options = SuperwallOptions()
options.isExternalDataCollectionEnabled = false
Superwall.configure(apiKey: "MY_API_KEY", options: options)
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.isExternalDataCollectionEnabled = false;
[Superwall configureWithApiKey:@"MY_API_KEY" purchaseController:nil options:options completion:nil];
```
:::
Disabling this will not affect your ability to create triggers based on properties.
### Automatically Dismissing the Paywall
By default, Superwall automatically dismisses the paywall when a product is purchased or restored. You can disable this by setting `automaticallyDismiss` to `false`:
:::ios
```swift Swift
let options = SuperwallOptions()
options.paywalls.automaticallyDismiss = false
Superwall.configure(apiKey: "MY_API_KEY", options: options)
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.automaticallyDismiss = false;
[Superwall configureWithApiKey:@"MY_API_KEY" purchaseController:nil options:options completion:^{}];
```
:::
To manually dismiss the paywall , call `Superwall.shared.dismiss()`.
### Custom Restore Failure Message
You can set the title, message and close button title for the alert that appears after a restoration failure:
:::ios
```swift Swift
let options = SuperwallOptions()
options.paywalls.restoreFailed.title = "My Title"
options.paywalls.restoreFailed.message = "My message"
options.paywalls.restoreFailed.closeButtonTitle = "Close"
Superwall.configure(apiKey: "MY_API_KEY", options: options)
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.paywalls.restoreFailed.title = @"My Title";
options.paywalls.restoreFailed.message = @"My message";
options.paywalls.restoreFailed.closeButtonTitle = @"Close";
[Superwall configureWithApiKey:@"MY_API_KEY" purchaseController:nil options:options completion:nil];
```
:::
### Haptic Feedback
On iOS, the paywall uses haptic feedback by default after a user purchases or restores a product, opens a URL from the paywall, or closes the paywall. To disable this, set the `isHapticFeedbackEnabled` `PaywallOption` to false:
:::ios
```swift Swift
let options = SuperwallOptions()
options.paywalls.isHapticFeedbackEnabled = false
Superwall.configure(apiKey: "MY_API_KEY", options: options)
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.isHapticFeedbackEnabled = false;
[Superwall configureWithApiKey:@"MY_API_KEY" purchaseController:nil options:options completion:^{}];
```
:::
Note: Android does not use haptic feedback.
### Transaction Background View
During a transaction, we add a `UIActivityIndicator` behind the view to indicate a loading status. However, you can remove this by setting the `transactionBackgroundView` to `nil`:
:::ios
```swift Swift
let options = SuperwallOptions()
options.paywalls.transactionBackgroundView = nil
Superwall.configure(apiKey: "MY_API_KEY", options: options)
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.paywalls.transactionBackgroundView = SWKTransactionBackgroundViewNone;
[Superwall
configureWithApiKey:@"MY_API_KEY"
purchaseController:nil
options:options
completion:nil
];
```
:::
### Purchase Failure Alert
When a purchase fails, we automatically present an alert with the error message. If you'd like to show your own alert after failure, set the `shouldShowPurchaseFailureAlert` `PaywallOption` to `false`:
:::ios
```swift Swift
let options = SuperwallOptions()
options.paywalls.shouldShowPurchaseFailureAlert = false
Superwall.configure(apiKey: "MY_API_KEY", options: options)
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.paywalls.shouldShowPurchaseFailureAlert = false;
[Superwall
configureWithApiKey:@"MY_API_KEY"
purchaseController:nil
options:options
completion:nil
];
```
:::
### Locale Identifier
When evaluating rules, the device locale identifier is set to `autoupdatingCurrent`. However, you can override this if you want to test a specific locale:
:::ios
```swift Swift
let options = SuperwallOptions()
options.localeIdentifier = "en_GB"
Superwall.configure(apiKey: "MY_API_KEY", options: options)
// Or you can set:
Superwall.shared.localeIdentifier = "en_GB"
// To revert to default:
Superwall.shared.localeIdentifier = nil
```
```swift Objective-C
SWKSuperwallOptions *options = [[SWKSuperwallOptions alloc] init];
options.localeIdentifier = @"en_GB";
[Superwall configureWithApiKey:@"MY_API_KEY" purchaseController:nil options:options completion:^{}];
// Or you can set:
[Superwall sharedInstance].localeIdentifier = "en_GB"
// To revert to default:
[Superwall sharedInstance].localeIdentifier = nil
```
:::
For a list of locales that are available on iOS, take a look at [this list](https://gist.github.com/jacobbubu/1836273). You can also preview your paywall in different locales using [In-App Previews](/docs/in-app-paywall-previews).
### Game Controller
If you're using a game controller, you can enable this in `SuperwallOptions` too. Check out our [Game Controller Support](/docs/game-controller-support) article.
Take a look at [SuperwallOptions](https://sdk.superwall.me/documentation/superwallkit/superwalloptions) in our SDK reference for more info.

# Experimental Flags
Source: https://superwall.com/docs/ios/guides/experimental-flags
undefined
Experimental flags in Superwall's SDK allow you to opt into features that are safe for production but are still being refined. These features may undergo naming changes or internal restructuring in future SDK versions. We expose them behind flags to give you early access while preserving flexibility for ongoing development.
These flags are configured via the `SuperwallOptions` struct:
```swift
let options = SuperwallOptions()
options.enableExperimentalDeviceVariables = true
Superwall.configure(apiKey: "my_api_key",
options: options)
```
## Available experimental flags
When these flags are enabled and the user runs your app, these values become available in campaign filters. Currently, these include:
**Latest Subscription Period Type (String)**:
Represents whether the user is in a trial, promotional, or a similar phase. Possible values include:
* `trial`
* `code`
* `subscription`
* `promotional`
* `winback`
* `revoked`
Represented as `latestSubscriptionPeriodType` in campaign filters.
**Latest Subscription State (String)**:
Represents what *state* the actual subscription is in. Possible values include:
* `inGracePeriod`
* `subscribed`
* `expired`
* `inBillingRetryPeriod`
* `revoked`
Represented as `latestSubscriptionState` in campaign filters.
**Latest Subscription Will Auto Renew (Bool)**:
If the user is set to renew or not. Either `true` or `false`
Represented as `latestSubscriptionWillAutoRenew` in campaign filters.
### Detecting users who've cancelled an active trial
One common use case for these flags is detecting users who've cancelled an active trial. In that case, the filter in the campaign would check for `latestSubscriptionWillAutoRenew` to be `false` and `latestSubscriptionPeriodType` to be `trial`.

# Migrating from v2 to v3 - iOS
Source: https://superwall.com/docs/ios/guides/migrations/migrating-to-v3
SuperwallKit 3.0 is a major release of Superwall's iOS SDK, previously known as `Paywall`. This introduces breaking changes.
Note that the minimum deployment target has changed for v3 from iOS 11 to iOS 13
This is so that we can use newer APIs internally and externally.
## Migration steps
### 1. Update Swift Package Manager dependency (if needed)
Our GitHub URL has changed. Although you can keep using the old one, its best if you replace it with the newer one. If you're using Swift Package Manager to handle dependencies:
* Select your project from the **Project Navigator**, select your project under **Project** and click **Package Dependencies**.
* Remove the old dependency for `paywall-ios`.
* Click **+** and search for our new url [https://github.com/superwall/Superwall-iOS](https://github.com/superwall/Superwall-iOS) in the search bar.
* Set the **Dependency Rule** to **Up to Next Major Version** with the lower bound set to **3.0.0**.
* Make sure your project name is selected in **Add to Project**.
* Then, **Add Package**.
Sometimes Xcode keeps the old framework reference around by accident, so select your target in Xcode, then go to Build Phases, and ensure that your target’s Link Binary with Libraries section references SuperwallKit, and remove the reference to Paywall if it was still there.

If you have any Xcode issues during building you might need to clean the build folder by going to
**Product** > **Clean Build Folder** and then restart Xcode.
### 1.1 Update CocoaPods dependency (if needed)
If instead you're using CocoaPods to manage dependencies, in your Podfile update the reference to the Pod from `Paywall` to `SuperwallKit` then run `pod install`:
| Before | After |
| ------------------------- | ------------------------------ |
| pod 'Paywall', '\< 3.0.0' | pod 'SuperwallKit', '\< 4.0.0' |
### 1.2 Update Framework References
Since our framework is now called `SuperwallKit`, you'll now need to explicitly import `SuperwallKit` instead of `Paywall` throughout your code:
#### Swift
| Before | After |
| -------------- | ------------------- |
| import Paywall | import SuperwallKit |
#### Objective-C
| Before | After |
| ---------------- | --------------------- |
| @import Paywall; | @import SuperwallKit; |
## 2. Update code references
In some cases, you should be able to update references using the automatic renaming suggestions that Xcode provides. For other cases where this hasn't been possible, you'll need to run through this list to manually update your code.
### 2.1 Update references to `Paywall.foo` to `Superwall.shared.foo`
You'll see errors saying `Cannot find 'Paywall' in scope`. This is because the main class for interacting with our API is now called `Superwall`. All variables and functions (apart from configure) are now instance functions. This means you'll need to use the shared instance `Superwall.shared`.
### 2.2 Triggering is now registering
Previously you'd use `Paywall.track(...)` to implicitly trigger a paywall, and `Paywall.trigger(...)` to explicitly trigger a paywall. This was confusing as they essentially did the same thing. `Paywall.track` provided completion blocks for what happened on the paywall when really you needed to know what to do next. We wanted to make this simpler so at the heart of this release is `Superwall.shared.register(event:params:handler:feature:)`. This allows you to register an event to access a feature that may or may not be paywalled later in time. It also allows you to choose whether the user can access the feature even if they don't make a purchase.
You can read our docs on [how register works](/docs/feature-gating) to learn more.
Given the low cost nature of how register works, we strongly recommend wrapping all core functionality in a register `feature` block in order to remotely configure which features you want to gate – without an app update.
For SwiftUI apps, we have removed the `.triggerPaywall` view modifier in favor of this register function.
### **2.3 Rename `PaywallDelegate` to `SuperwallDelegate`**
The following method has changed:
| Before | After |
| ----------------------------------------------------------------------- | --------------------------------------------------------------------- |
| func trackAnalyticsEvent(withName name: String, params: \[String: Any]) | func handleSuperwallEventInfo(withInfo eventInfo: SuperwallEventInfo) |
This has a `SuperwallEventInfo` parameter. This has a `params` dictionary and an `event` enum whose cases contain associated values. Note that the methods for handling subscription-related logic no longer exist inside `SuperwallDelegate`, as discussed in the next section.
### 2.4 Handling subscription-related logic
SuperwallKit now handles all subscription-related logic by default making integration super easy. We track the user's subscription status for you and expose the published property `Superwall.shared.subscriptionStatus`. This means that if you were previously using StoreKit you can simply delete that code and let SuperwallKit handle it.
However, if you're using RevenueCat or still want to keep control over subscription-related logic, you'll need to conform to the `PurchaseController` protocol. This is a protocol that handles purchasing and restoring, much like the `PaywallDelegate` did in v2.x of the SDK. You set the purchase controller when you configure the SDK. You can read more about that in our [Purchases and Subscription Status](/docs/advanced-configuration) guide.
The following methods were previously in the `PaywallDelegate` but are now in the `PurchaseController` and have changed slightly:
#### Purchasing
| Before | After |
| --------------------------------- | --------------------------------------------------------- |
| func purchase(product: SKProduct) | func purchase(product: SKProduct) async -> PurchaseResult |
Here, you purchase the product but then return the result of the purchase as a `PurchaseResult` enum case. Make sure you handle all cases of `PurchaseResult`.
#### Restoring
| Before | After |
| ----------------------------------------------------------- | -------------------------------------------------- |
| func restorePurchases(completion: @escaping (Bool) -> Void) | func restorePurchases() async -> RestorationResult |
This has changed to an async function that returns the result of restoring a purchase. If you need help converting between completion blocks and async, [check out this article](https://wwdcbysundell.com/2021/wrapping-completion-handlers-into-async-apis/).
#### Subscription Status
| Before | After |
| ------------------------------- | ------------------------------------------------------------ |
| func isUserSubscribed() -> Bool | Superwall.shared.subscriptionStatus = .active (or .inactive) |
`isUserSubscribed()` has been removed in favor of a `subscriptionStatus` variable which you **must** set every time the user's subscription status changes. On first app install this starts off as `.unknown` until you determine the user's subscription status and set it to `.active` when they have an active subscription, or `.inactive` when they don't. Paywalls will not show until the user's subscription status is set.
You can [check out our docs](/docs/advanced-configuration) for detailed info about implementing the `PurchaseController`.
### 2.5 Rename `PaywallOptions` to `SuperwallOptions`
This now clearly defines which of the options are explicit to paywalls vs other configuration options within the SDK.
### 2.6 Configuring and Identity management
When configuring the API, you now no longer provide a userId or delegate.
| Before | After |
| --------------------------------------------- | ----------------------------------------------------------- |
| configure(apiKey\:userId\:delegate\:options:) | configure(apiKey\:purchaseController\:options\:completion:) |
To use the optional delegate, set `Superwall.shared.delegate`. To identify a user, use `Superwall.shared.identify(userId:options:)`.
You can [read more](/docs/identity-management) about identity management in our docs.
## 3. Check out the full change log
You can view this on [our GitHub page](https://github.com/superwall/Superwall-iOS/blob/master/CHANGELOG.md).
## 4. Check out our updated example apps
All of our example apps have been updated to use the latest SDK. We have created a dedicated app that shows you how to integrate Superwall with RevenueCat. In addition, we have added an Objective-C app.

# Migrating from v3 to v4 - iOS
Source: https://superwall.com/docs/ios/guides/migrations/migrating-to-v4
SuperwallKit 4.0 is a major release of Superwall's iOS SDK. This introduces breaking changes.
## Migration steps
## 1. Update code references
### 1.1 Rename references from `event` to `placement`
In some cases, you should be able to update references using the automatic renaming suggestions that Xcode provides. For other cases where this hasn't been possible, you'll need to run through this list to manually update your code.
| Before | After |
| ------------------------------------- | ----------------------------------------- |
| func register(event:) | func register(placement:) |
| func preloadPaywalls(forEvents:) | func preloadPaywalls(forPlacements:) |
| func getPaywall(forEvent:) | func getPaywall(forPlacement:) |
| func getPresentationResult(forEvent:) | func getPresentationResult(forPlacement:) |
| TriggerResult.eventNotFound | TriggerResult.placementNotFound |
### 1.2 Update PurchaseController method
The following has been changed in the `PurchaseController`:
| Before | After |
| --------------------------------------------------------- | ------------------------------------------------------------ |
| func purchase(product: SKProduct) async -> PurchaseResult | func purchase(product: StoreProduct) async -> PurchaseResult |
This provides a `StoreProduct` object, which contains information about the product to be purchased.
## 2. StoreKit 2
The SDK defaults to using StoreKit 2 for users who are on iOS 15+. However, you can choose to stay on StoreKit 1 by setting the `SuperwallOption` `storeKitVersion` to `.storeKit1`.
There are a few caveats to this however.
In the following scenarios, the SDK will choose StoreKit 1 automatically:
1. If you're using Objective-C and using a `PurchaseController`.
2. If you're using Objective-C and observing purchases by setting the `SuperwallOption` `shouldObservePurchases` to `true`.
3. If you have set the key `SKIncludeConsumableInAppPurchaseHistory` to `true` in your info.plist, the SDK will use StoreKit 1 for everyone who isn't on iOS 18+.
If you're using Objective-C and using `purchase(_:)` you must manually set the `SuperwallOption` `storeKitVersion` to `.storeKit1`.
If you're using a `PurchaseController`, you access the StoreKit 2 product to purchase using `product.sk2Product` and the StoreKit 1 product `product.sk1Product` if
you're using StoreKit 1. You should take the above scenarios into account when choosing which product to purchase.
### 3. Getting the purchased product
The `onDismiss` block of the `PaywallPresentationHandler` now accepts both a `PaywallInfo` object and a `PaywallResult` object. This allows you to easily access
the purchased product from the result when the paywall dismisses.
### 4. Entitlements
The `subscriptionStatus` has been changed to accept a set of `Entitlement` objects. This allows you to give access to entitlements based on products purchased.
For example, in your app you might have Bronze, Silver, and Gold subscription tiers, i.e. entitlements, which entitle a user to access a certain set of features within your app.
Every subscription product must be associated with one or more entitlements, which is controlled via the dashboard. Superwall will already have associated all your
products with a default entitlement. If you don't use more than one entitlement tier within your app and you only use subscription products, you don't need to do anything extra.
However, if you use one-time purchases or multiple entitlements, you should review your products and their entitlements. In general, consumables should not be associated with an
entitlement, whereas non-consumables should be. Check your products [here](https://superwall.com/applications/\:app/products/v2).
If you're using a `PurchaseController`, you'll need to set the `entitlements.status` instead of the `subscriptionStatus`:
| Before | After |
| --------------------------------------------- | ---------------------------------------------------------------- |
| Superwall.shared.subscriptionStatus = .active | Superwall.shared.subscriptionStatus = .active(Set(entitlements)) |
You can get the `StoreProducts` and their associated entitlements from Superwall by calling the method `products(for:)`. Here is an example of how you'd sync your subscription
status with Superwall using these methods:
```swift Swift
func syncSubscriptionStatus() async {
var products: Set = []
for await verificationResult in Transaction.currentEntitlements {
switch verificationResult {
case .verified(let transaction):
products.insert(transaction.productID)
case .unverified:
break
}
}
let storeProducts = await Superwall.shared.products(for: products)
let entitlements = Set(storeProducts.flatMap { $0.entitlements })
await MainActor.run {
Superwall.shared.subscriptionStatus = .active(entitlements)
}
}
```
```swift RevenueCat
func syncSubscriptionStatus() {
assert(Purchases.isConfigured, "You must configure RevenueCat before calling this method.")
Task {
for await customerInfo in Purchases.shared.customerInfoStream {
// Gets called whenever new CustomerInfo is available
let superwallEntitlements = customerInfo.entitlements.activeInCurrentEnvironment.keys.map {
Entitlement(id: $0)
}
await MainActor.run { [superwallEntitlements] in
if superwallEntitlements.isEmpty {
Superwall.shared.subscriptionStatus = .inactive
} else {
Superwall.shared.subscriptionStatus = .active(Set(superwallEntitlements))
}
}
}
}
}
```
You can listen to the published property `Superwall.shared.subscriptionStatus` to be notified when the subscriptionStatus changes. Or you can use the `SuperwallDelegate`
method `subscriptionStatusDidChange(from:to:)`, which replaces `subscriptionStatusDidChange(to:)`.
### 5. Paywall Presentation Condition
In the Paywall Editor you can choose whether to always present a paywall or ask the SDK to check the user subscription before presenting a paywall.
For users on v4 of the SDK, this is replaced with a check on the entitlements within the audience filter. As you migrate your users from v3 to v4 of the
SDK, you'll need to make sure you set both the entitlements check and the paywall presentation condition in the paywall editor.

## 6. Check out the full change log
You can view this on [our GitHub page](https://github.com/superwall/Superwall-iOS/blob/master/CHANGELOG.md).
## 7. Check out our updated example apps
All of our example apps have been updated to use the latest SDK. We now only have two apps: Basic and Advanced. Basic shows you the basic integration of Superwall
without needing a purchase controller or multiple entitlements. Advanced shows you how to use entitlements within your app as well as optionally using a purchase controller
with StoreKit or RevenueCat.

# Setting up StoreKit testing
Source: https://superwall.com/docs/ios/guides/testing-purchases
undefined
StoreKit testing in Xcode is a local test environment for testing in-app purchases without requiring a connection to App Store servers. Set up in-app purchases in a local StoreKit configuration file in your Xcode project, or create a synced StoreKit configuration file in Xcode from your in-app purchase settings in App Store Connect. After you enable the configuration file, the test environment uses this local data on your paywalls when your app calls StoreKit APIs.
### Add a StoreKit Configuration File
Go to **File ▸ New ▸ File...** in the menu bar , select **StoreKit Configuration File** and hit **Next**:

Give it the name **Products**. For a configuration file synced with an app on App Store Connect, select the checkbox, specify your team and app in the drop-down menus that appear, then click **Next**. For a local configuration, leave the checkbox unselected, then click **Next**. Save the file in the top-level folder of your project. You don't need to add it to your target.
### Create a New Scheme for StoreKit Testing
It's best practice to create a new scheme in Xcode to be used for StoreKit testing. This allows you to separate out staging and production environments.
Click the scheme in the scheme menu and click **Manage Schemes...**:

If you haven't already got a Staging scheme, select your current scheme and click **Duplicate**:

In the scheme editor, add the StoreKit Configuration file to your scheme by clicking on **Run** in the side bar, selecting the **Options** tab and choosing your configuration file in **StoreKit Configuration**. Then, click **Close**:

You can rename your scheme to **MyAppName (Staging)**.
### Setting up the StoreKit Configuration File
If you've chosen to sync your configuration file with the App Store, your apps will automatically be loaded into your StoreKit Configuration file. When you add new products, just sync again.
If you're using a local configuration, open **Products.storekit**, click the **+** button at the bottom and create a new product. In this tutorial, we'll create an auto-renewable subscription:

Enter a name for a new subscription group and click **Done**. The subscription group name should match one that is set up for your app in App Store Connect, but it's not a requirement. That means you can test your subscription groups and products in the simulator and then create the products in App Store Connect later:

Configure the subscription as needed by filling in the **Reference Name**, **Product ID**, **Price**, **Subscription Duration**, and optionally an **Introductory Offer**. Again, this product doesn't have to exist in App Store Connect for you to test purchasing in the simulator. Here is a sample configuration:

Repeat this for all of your products. When configuring a paywall, the product ID you enter here must match the product ID on the paywall.
You're now all set!
## Testing purchases with Transaction Manager
Once you've set up your StoreKit configuration file, you can leverage Xcode's Transaction Manager. Find it under **Debug -> StoreKit -> Manage Transactions...**:

Use this to quickly test purchasing your products. Once you make a purchase, you can open Transaction Manager to delete it, refund it, request parental approval and much more. Most commonly, you'll probably delete the transaction to reset your subscription state:

This makes everything a little faster, saving you the trouble of having to delete and reinstall your app to test these states. If you'd like to see a video over how to use it, check this one out:

# Using RevenueCat
Source: https://superwall.com/docs/ios/guides/using-revenuecat
undefined
Not using RevenueCat? No problem! Superwall works out of the box without any additional SDKs.
You can integrate RevenueCat with Superwall using several approaches:
## Class-Based Integration
You can integrate RevenueCat with Superwall using purchase controllers:
1. **Using a purchase controller:** Use this route if you want to maintain control over purchasing logic and code.
2. **Using PurchasesAreCompletedBy:** Here, you don't use a purchase controller and you tell RevenueCat that purchases are completed by your app using StoreKit. In this mode, RevenueCat will observe the purchases that the Superwall SDK makes. For more info [see here](https://www.revenuecat.com/docs/migrating-to-revenuecat/sdk-or-not/finishing-transactions).
### 1. Create a PurchaseController
Create a new file called `RCPurchaseController`, then copy and paste the following:
:::ios
```swift
import SuperwallKit
import RevenueCat
import StoreKit
enum PurchasingError: LocalizedError {
case sk2ProductNotFound
var errorDescription: String? {
switch self {
case .sk2ProductNotFound:
return "Superwall didn't pass a StoreKit 2 product to purchase. Are you sure you're not "
+ "configuring Superwall with a SuperwallOption to use StoreKit 1?"
}
}
}
final class RCPurchaseController: PurchaseController {
// MARK: Sync Subscription Status
/// Makes sure that Superwall knows the customer's entitlements by
/// changing `Superwall.shared.entitlements`
func syncSubscriptionStatus() {
assert(Purchases.isConfigured, "You must configure RevenueCat before calling this method.")
Task {
for await customerInfo in Purchases.shared.customerInfoStream {
// Gets called whenever new CustomerInfo is available
let superwallEntitlements = customerInfo.entitlements.activeInCurrentEnvironment.keys.map {
Entitlement(id: $0)
}
await MainActor.run { [superwallEntitlements] in
Superwall.shared.subscriptionStatus = .active(Set(superwallEntitlements))
}
}
}
}
// MARK: Handle Purchases
/// Makes a purchase with RevenueCat and returns its result. This gets called when
/// someone tries to purchase a product on one of your paywalls.
func purchase(product: SuperwallKit.StoreProduct) async -> PurchaseResult {
do {
guard let sk2Product = product.sk2Product else {
throw PurchasingError.sk2ProductNotFound
}
let storeProduct = RevenueCat.StoreProduct(sk2Product: sk2Product)
let revenueCatResult = try await Purchases.shared.purchase(product: storeProduct)
if revenueCatResult.userCancelled {
return .cancelled
} else {
return .purchased
}
} catch let error as ErrorCode {
if error == .paymentPendingError {
return .pending
} else {
return .failed(error)
}
} catch {
return .failed(error)
}
}
// MARK: Handle Restores
/// Makes a restore with RevenueCat and returns `.restored`, unless an error is thrown.
/// This gets called when someone tries to restore purchases on one of your paywalls.
func restorePurchases() async -> RestorationResult {
do {
_ = try await Purchases.shared.restorePurchases()
return .restored
} catch let error {
return .failed(error)
}
}
}
```
:::
As discussed in [Purchases and Subscription Status](/docs/advanced-configuration), this `PurchaseController` is responsible for handling the subscription-related logic. Take a few moments to look through the code to understand how it does this.
#### 2. Configure Superwall
Initialize an instance of `RCPurchaseController` and pass it in to `Superwall.configure(apiKey:purchaseController)`:
:::ios
```swift
let purchaseController = RCPurchaseController()
Superwall.configure(
apiKey: "MY_API_KEY",
purchaseController: purchaseController
)
```
:::
#### 3. Sync the subscription status
Then, call `purchaseController.syncSubscriptionStatus()` to keep Superwall's subscription status up to date with RevenueCat.
That's it! Check out our sample app for working examples:
:::ios
* [iOS](https://github.com/superwall/Superwall-iOS/tree/master/Examples/Advanced)
:::
### Using PurchasesAreCompletedBy
If you're using RevenueCat's [PurchasesAreCompletedBy](https://www.revenuecat.com/docs/migrating-to-revenuecat/sdk-or-not/finishing-transactions), you don't need to create a purchase controller. Register your placements, present a paywall — and Superwall will take care of completing any purchase the user starts. However, there are a few things to note if you use this setup:
1. Here, you aren't using RevenueCat's [entitlements](https://www.revenuecat.com/docs/getting-started/entitlements#entitlements) as a source of truth. If your app is multiplatform, you'll need to consider how to link up pro features or purchased products for users.
2. If you require custom logic when purchases occur, then you'll want to add a purchase controller. In that case, Superwall handles purchasing flows and RevenueCat will still observe transactions to power their analytics and charts.
3. Be sure that user identifiers are set the same way across Superwall and RevenueCat.
:::ios
Example:
```swift
Superwall.configure(apiKey: "superwall_public_key")
Superwall.shared.identify(userId: user.identifier)
Purchases.configure(with:
.builder(withAPIKey: "revcat_public_key")
.with(purchasesAreCompletedBy: .myApp, storeKitVersion: .storeKit1/.storeKit2)
.with(appUserID: user.identifier)
.build()
)
```
:::

# Using the Superwall Delegate
Source: https://superwall.com/docs/ios/guides/using-superwall-delegate
undefined
Use Superwall's delegate to extend our SDK's functionality across several surface areas by assigning to the `delegate` property:
:::ios
```swift Swift
class SWDelegate: SuperwallDelegate {
// Implement delegate methods here
}
// After configuring the SDK...
Superwall.shared.delegate = SWDelegate()
```
```swift Objective-C
// In its own file...
#import
@import SuperwallKit;
@interface SWDelegate : NSObject
@end
@implementation SWDelegate
// Implement delegate methods here
@end
// After configuring the SDK...
[[Superwall sharedInstance] setDelegate:[SWDelegate new]];
```
:::
Some common use cases for using the Superwall delegate include:
* **Custom actions:** [Respond to custom tap actions from a paywall.](/custom-paywall-events#custom-paywall-actions)
* **Respond to purchases:** [See which product was purchased from the presented paywall.](/viewing-purchased-products)
* **Analytics:** [Forward events from Superwall to your own analytics.](/3rd-party-analytics)
Below are some commonly used implementations when using the delegate.
### Superwall Events
Most of what occurs in Superwall can be viewed using the delegate method to respond to events:
:::ios
```swift Swift
class SWDelegate: SuperwallDelegate {
func handleSuperwallEvent(withInfo eventInfo: SuperwallEventInfo) {
switch eventInfo.event {
case .transactionComplete(let transaction, let product, let paywallInfo):
print("Converted from paywall originalTransactionIdentifier: \(transaction?.originalTransactionIdentifier ?? "")")
print("Converted from paywall storeTransactionId: \(transaction?.storeTransactionId ?? "")")
print("Converted from paywall productIdentifier: \(product.productIdentifier)")
print("Converted from paywall paywallInfo: \(paywallInfo.identifier)")
case .transactionRestore(let restoreType, let paywallInfo):
print("transactionRestore restoreType \(restoreType)")
case let .customPlacement(name, params, paywallInfo):
// Forward Mixpanel/Ampltiude/etc
print("\(name) - \(params) - \(paywallInfo)")
default:
// And several more events to use...
print("Default event: \(eventInfo.event.description)")
}
}
}
```
```swift Objective-C
// SWDelegate.h...
#import
@import SuperwallKit;
NS_ASSUME_NONNULL_BEGIN
@interface SWDelegate : NSObject
@end
NS_ASSUME_NONNULL_END
// SWDelegate.m...
@implementation SWDelegate
- (void)handleSuperwallEventWithInfo:(SWKSuperwallEventInfo *)eventInfo {
switch(eventInfo.event) {
// Switch on any event type here...
case SWKSuperwallEventTransactionComplete:
NSLog(@"Transaction complete: %@", eventInfo.params[@"primary_product_id"]);
}
}
```
:::
### Paywall Custom Actions
Using the [custom tap action](/custom-paywall-events), you can respond to any arbitrary event from a paywall:
:::ios
```swift Swift
class SWDelegate: SuperwallDelegate {
func handleCustomPaywallAction(withName name: String) {
if name == "showHelpCenter" {
DispatchQueue.main.asyncAfter(deadline: .now() + 0.33) {
self.showHelpCenter.toggle()
}
}
}
}
```
```swift Objective-C
// SWDelegate.h...
#import
@import SuperwallKit;
NS_ASSUME_NONNULL_BEGIN
@interface SWDelegate : NSObject
@end
NS_ASSUME_NONNULL_END
// SWDelegate.m...
#import "SWDelegate.h"
@implementation SWDelegate
- (void)handleCustomPaywallActionWithName:(NSString *)name {
if ([name isEqualToString:@"showHelpCenter"]) {
[self showHelpCenter];
}
}
@end
```
:::
### Subscription status changes
You can be informed of subscription status changes using the delegate. If you need to set or handle the status on your own, use a [purchase controller](/advanced-configuration) — this function is only for informational, tracking or similar purposes:
:::ios
```swift Swift
class SWDelegate: SuperwallDelegate {
func subscriptionStatusDidChange(from oldValue: SubscriptionStatus, to newValue: SubscriptionStatus) {
// Log or handle subscription change in your Ui
}
}
```
```swift Objective-C
// SWDelegate.h...
#import
@import SuperwallKit;
NS_ASSUME_NONNULL_BEGIN
@interface SWDelegate : NSObject
@end
NS_ASSUME_NONNULL_END
// SWDelegate.m...
@implementation SWDelegate
- (void)subscriptionStatusDidChangeFrom:(enum SWKSubscriptionStatus)oldValue
to:(enum SWKSubscriptionStatus)newValue {
NSLog(@"Changed from %lu to %lu", (unsigned long)oldValue, (unsigned long)newValue);
}
@end
```
:::
### Paywall events
The delegate also has callbacks for several paywall events, such dismissing, presenting, and more. Here's an example:
:::ios
```swift Swift
class SWDelegate: SuperwallDelegate {
func didPresentPaywall(withInfo paywallInfo: PaywallInfo) {
// paywallInfo will contain all of the presented paywall's info
}
}
```
```swift Objective-C
// SWDelegate.h...
#import
@import SuperwallKit;
NS_ASSUME_NONNULL_BEGIN
@interface SWDelegate : NSObject
@end
NS_ASSUME_NONNULL_END
// SWDelegate.m...
@implementation SWDelegate
- (void)didPresentPaywallWithInfo:(SWKPaywallInfo *)paywallInfo {
NSLog(@"Presented paywall with info: %@", paywallInfo);
}
@end
```

# Redeeming In-App
Source: https://superwall.com/docs/ios/guides/web-checkout/linking-membership-to-iOS-app
Handle a deep link in your app and use the delegate methods.
After purchasing from a web paywall, the user will be redirected to your app by a deep link to redeem their purchase on device.
Please follow our [Post-Checkout Redirecting](/web-checkout-post-checkout-redirecting) guide to handle this user experience.
If you're using Superwall to handle purchases, then you don't need to do anything here.
If you're using your own `PurchaseController`, you will need to update the subscription status with the redeemed web entitlements. If you're using RevenueCat, you should follow our [Using RevenueCat](/web-checkout-using-revenuecat) guide.
### Using a PurchaseController
If you're using StoreKit in your PurchaseController, you'll need to merge the web entitlements with the device entitlements before setting the subscription status.
Here's an example of how you might do this:
```swift
func syncSubscriptionStatus() async {
var products: Set = []
// Get the device entitlements
for await verificationResult in Transaction.currentEntitlements {
switch verificationResult {
case .verified(let transaction):
products.insert(transaction.productID)
case .unverified:
break
}
}
let storeProducts = await Superwall.shared.products(for: products)
let deviceEntitlements = Set(storeProducts.flatMap { $0.entitlements })
// Get the web entitlements from Superwall
let webEntitlements = Superwall.shared.entitlements.web
// Merge the two sets of entitlements
let allEntitlements = deviceEntitlements.union(webEntitlements)
await MainActor.run {
Superwall.shared.subscriptionStatus = .active(allEntitlements)
}
}
```
In addition to syncing the subscription status when purchasing and restoring, you'll need to sync it whenever `didRedeemLink(result:)` is called:
```swift
final class Delegate: SuperwallDelegate {
func didRedeemLink(result: RedemptionResult) {
Task {
await syncSubscriptionStatus()
}
}
}
```
### Refreshing of web entitlements
If you aren't using a Purchase Controller, the SDK will refresh the web entitlements every 24 hours.
### Redeeming while a paywall is open
If a redeem event occurs when a paywall is open, the SDK will track that as a restore event and the paywall will close.

# Post-Checkout Redirecting
Source: https://superwall.com/docs/ios/guides/web-checkout/post-checkout-redirecting
Learn how to handle users redirecting back to your app after a web purchase.
Whether you’re showing a checkout page in Safari or using the In-App Browser, the Superwall SDK relies on deep links to redirect back to your app.
#### Prerequisites
1. [Configuring Stripe Keys and Settings](/web-checkout-configuring-stripe-keys-and-settings)
2. [Deep Links](/in-app-paywall-previews)
Here, we'll focus on how to handle the user experience when the user has been redirected back to your app after a web purchase, using `SuperwallDelegate` methods.
If you're not using Superwall to handle purchases, then you'll need to follow extra steps to redeem the web purchase in your app.
* [Using RevenueCat](/web-checkout-using-revenuecat)
* [Using a PurchaseController](/web-checkout-linking-membership-to-iOS-app#using-a-purchasecontroller)
## willRedeemLink
When your app opens via the deep link, we will call the delegate method `willRedeemLink()` before making a network call to redeem the code.
At this point, you might wish to display a loading indicator in your app so the user knows that the purchase is being redeemed.
```swift
func willRedeemLink() {
ToastView.show(message: "Activating...", showActivityIndicator: true)
}
```
To present your own loading UI on top of the paywall, you can access the view controller of the paywall via `Superwall.shared.presentedViewController`. You can manually dismiss the paywall here, but note that the completion block of the original `register` call won't be triggered. The paywall will be dismissed automatically when the `didRedeemLink` method is called.
## didRedeemLink
After receiving a response from the network, we will call `didRedeemLink(result:)` with the result of redeeming the code. This is an enum that has the following cases:
* `success(code: String, redemptionInfo: RedemptionInfo)`: The redemption succeeded and `redemptionInfo` contains information about the redeemed code.
* `error(code: String, error: ErrorInfo)`: An error occurred while redeeming. You can check the error message via the `error` parameter.
* `expiredCode(code: String, expired: ExpiredCodeInfo)`: The code expired and `ExpiredCodeInfo` contains information about whether a redemption email has been resent and an optional obfuscated email address that the redemption email was sent to.
* `invalidCode(code: String)`: The code that was redeemed was invalid.
* `expiredSubscription(code: String, redemptionInfo: RedemptionInfo)`: The subscription that the code redeemed has expired.
On network failure, the SDK will retry up to 6 times before returning an `error` `RedemptionResult` in `didRedeemLink(result:)`.
Here, you should remove any loading UI you added in `willRedeemLink` and show a message to the user based on the result. If a paywall is presented, it will be dismissed automatically.
```swift
func didRedeemLink(result: RedemptionResult) {
switch result {
case .expiredCode(let code, let expiredInfo):
ToastView.show(message: "Expired Link", systemImageName: "exclamationmark.square.fill")
print("[!] code expired", code, expiredInfo)
break
case .error(let code, let error):
ToastView.show(message: error.message, systemImageName: "exclamationmark.square.fill")
print("[!] error", code, error)
break
case .expiredSubscription(let code, let redemptionInfo):
ToastView.show(message: "Expired Subscription", systemImageName: "exclamationmark.square.fill")
print("[!] expired subscription", code, redemptionInfo)
break
case .invalidCode(let code):
ToastView.show(message: "Invalid Link", systemImageName: "exclamationmark.square.fill")
print("[!] invalid code", code)
break
case .success(_, let redemptionInfo):
if let email = redemptionInfo.purchaserInfo.email {
Superwall.shared.setUserAttributes(["email": email])
ToastView.show(message: email, systemImageName: "person.circle.fill")
}
else {
ToastView.show(message: "Welcome!", systemImageName: "person.circle.fill")
}
break
}
}
```

# Using RevenueCat
Source: https://superwall.com/docs/ios/guides/web-checkout/using-revenuecat
Handle a deep link in your app and use the delegate methods to link web checkouts with RevenueCat.
After purchasing from a web paywall, the user will be redirected to your app by a deep link to redeem their purchase on device. Please follow our [Post-Checkout Redirecting](/web-checkout-post-checkout-redirecting) guide to handle this user experience.
If you're using Superwall to handle purchases, then you don't need to do anything here.
If you're using your own `PurchaseController`, you should follow our [Redeeming In-App](/web-checkout-linking-membership-to-iOS-app) guide.
### Using a PurchaseController with RevenueCat
If you're using RevenueCat, you'll need to follow [steps 1 to 4 in their guide](https://www.revenuecat.com/docs/web/integrations/stripe) to set up Stripe with RevenueCat. Then, you'll need to
associate the RevenueCat customer with the Stripe subscription IDs returned from redeeming the code. You can do this by extracting the ids from the `RedemptionResult` and sending them to RevenueCat's API
by using the `didRedeemLink(result:)` delegate method:
```swift
import Foundation
import RevenueCat
final class Delegate: SuperwallDelegate {
// The user tapped on a deep link to redeem a code
func willRedeemLink() {
print("[!] willRedeemLink")
// Optionally show a loading indicator here
}
// Superwall received a redemption result and validated the purchase with Stripe.
func didRedeemLink(result: RedemptionResult) {
print("[!] didRedeemLink", result)
// Send Stripe IDs to RevenueCat to link purchases to the customer
// Get a list of subscription ids tied to the customer.
guard let stripeSubscriptionIds = result.stripeSubscriptionIds else { return }
guard let url = URL(string: "https://api.revenuecat.com/v1/receipts") else { return }
let revenueCatStripePublicAPIKey = "strp....." // replace with your RevenueCat Stripe Public API Key
let appUserId = Purchases.shared.appUserID
// In the background...
Task.detached {
await withTaskGroup(of: Void.self) { group in
// For each subscription id, link it to the user in RevenueCat
for stripeSubscriptionId in stripeSubscriptionIds {
group.addTask {
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")
request.setValue("stripe", forHTTPHeaderField: "X-Platform")
request.setValue("Bearer \(revenueCatStripePublicAPIKey)", forHTTPHeaderField: "Authorization")
do {
request.httpBody = try JSONEncoder().encode([
"app_user_id": appUserId,
"fetch_token": stripeSubscriptionId
])
let (data, _) = try await URLSession.shared.data(for: request)
let json = try JSONSerialization.jsonObject(with: data, options: [])
print("[!] Success: linked \(stripeSubscriptionId) to user \(appUserId)", json)
} catch {
print("[!] Error: unable to link \(stripeSubscriptionId) to user \(appUserId)", error)
}
}
}
}
/// After all network calls complete, invalidate the cache without switching to the main thread.
Purchases.shared.getCustomerInfo(fetchPolicy: .fetchCurrent) { customerInfo, error in
/// If you're using `Purchases.shared.customerInfoStream`, or keeping Superwall Entitlements in sync
/// via RevenueCat's `PurchasesDelegate` methods, you don't need to do anything here. Those methods will be
/// called automatically when this call fetches the most up to customer info, ignoring any local caches.
/// Otherwise, if you're manually calling `Purchases.shared.getCustomerInfo` to keep Superwall's entitlements
/// in sync, you should use the newly updated customer info here to do so.
}
/// You could always access web entitlements here as well
/// `let webEntitlements = Superwall.shared.entitlements.web`
// After all network calls complete...
await MainActor.run {
// Perform UI updates on the main thread, like letting the user know their subscription was redeemed
}
}
}
}
```
If you call `logIn` from RevenueCat's SDK, then you need to call the logic you've implemented
inside `didRedeemLink(result:)` again. For example, that means if `logIn` was invoked from
RevenueCat, you'd either abstract out this logic above into a function to call again, or simply
call this function directly.
The web entitlements will be returned along with other existing entitlements in the `CustomerInfo` object accessible via RevenueCat's SDK.
If you’re logging in and out of RevenueCat, make sure to resend the Stripe subscription IDs to RevenueCat’s endpoint after logging in.

# Configure the SDK
Source: https://superwall.com/docs/ios/quickstart/configure
undefined
As soon as your app launches, you need to configure the SDK with your **Public API Key**. You'll retrieve this from the Superwall settings page.
### Sign Up & Grab Keys
If you haven't already, [sign up for a free account](https://superwall.com/sign-up) on Superwall. Then, when you're through to the Dashboard, click **Settings** from the panel on the left, click **Keys** and copy your **Public API Key**:

### Initialize Superwall in your app
Begin by editing your main Application entrypoint. Depending on the
platform this could be `AppDelegate.swift` or `SceneDelegate.swift` for iOS,
`MainApplication.kt` for Android, `main.dart` in Flutter, or `App.tsx` for React Native:
:::ios
```swift Swift-UIKit
// AppDelegate.swift
import UIKit
import SuperwallKit
@main
final class AppDelegate: UIResponder, UIApplicationDelegate {
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
Superwall.configure(apiKey: "MY_API_KEY") // Replace this with your API Key
return true
}
}
```
```swift SwiftUI
// App.swift
import SwiftUI
import SuperwallKit
@main
struct MyApp: App {
init() {
let apiKey = "MY_API_KEY" // Replace this with your API Key
Superwall.configure(apiKey: apiKey)
}
// etc...
}
```
```swift Objective-C
// AppDelegate.m
@import SuperwallKit;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Initialize the Superwall service.
[Superwall configureWithApiKey:@"MY_API_KEY"];
return YES;
}
```
:::
This configures a shared instance of `Superwall`, the primary class for interacting with the SDK's API. Make sure to replace `MY_API_KEY` with your public API key that you just retrieved.
By default, Superwall handles basic subscription-related logic for you. However, if you’d like
greater control over this process (e.g. if you’re using RevenueCat), you’ll want to pass in a
`PurchaseController` to your configuration call and manually set the `subscriptionStatus`. You can
also pass in `SuperwallOptions` to customize the appearance and behavior of the SDK. See
[Purchases and Subscription Status](/advanced-configuration) for more.
You've now configured Superwall!
:::ios
For further help, check out our [iOS example apps](https://github.com/superwall/Superwall-iOS/tree/master/Examples) for working examples of implementing the Superwall SDK.

# Presenting Paywalls
Source: https://superwall.com/docs/ios/quickstart/feature-gating
Control access to premium features with Superwall placements
This allows you to register a [placement](/campaigns-placements) to access a feature that may or may not be paywalled later in time. It also allows you to choose whether the user can access the feature even if they don't make a purchase.
Here's an example.
#### With Superwall
:::ios
```swift Swift
func pressedWorkoutButton() {
// remotely decide if a paywall is shown and if
// navigation.startWorkout() is a paid-only feature
Superwall.shared.register(placement: "StartWorkout") {
navigation.startWorkout()
}
}
```
```swift Objective-C
- (void)pressedWorkoutButton {
// remotely decide if a paywall is shown and if
// navigation.startWorkout() is a paid-only feature
[[Superwall sharedInstance] registerWithPlacement:@"StartWorkout" params:nil handler:nil feature:^{
[navigation startWorkout];
}];
}
```
:::
#### Without Superwall
:::ios
```swift Swift
func pressedWorkoutButton() {
if (user.hasActiveSubscription) {
navigation.startWorkout()
} else {
navigation.presentPaywall() { result in
if (result) {
navigation.startWorkout()
} else {
// user didn't pay, developer decides what to do
}
}
}
}
```
```swift Objective-C
- (void)pressedWorkoutButton {
if (user.hasActiveSubscription) {
[navigation startWorkout];
} else {
[navigation presentPaywallWithCompletion:^(BOOL result) {
if (result) {
[navigation startWorkout];
} else {
// user didn't pay, developer decides what to do
}
}];
}
}
```
:::
### How registering placements presents paywalls
You can configure `"StartWorkout"` to present a paywall by [creating a campaign, adding the placement, and adding a paywall to an audience](/campaigns) in the dashboard.
1. The SDK retrieves your campaign settings from the dashboard on app launch.
2. When a placement is called that belongs to a campaign, audiences are evaluated ***on device*** and the user enters an experiment — this means there's no delay between registering a placement and presenting a paywall.
3. If it's the first time a user is entering an experiment, a paywall is decided for the user based on the percentages you set in the dashboard
4. Once a user is assigned a paywall for an audience, they will continue to see that paywall until you remove the paywall from the audience or reset assignments to the paywall.
5. After the paywall is closed, the Superwall SDK looks at the *Feature Gating* value associated with your paywall, configurable from the paywall editor under General > Feature Gating (more on this below)
1. If the paywall is set to ***Non Gated***, the `feature:` closure on `register(placement: ...)` gets called when the paywall is dismissed (whether they paid or not)
2. If the paywall is set to ***Gated***, the `feature:` closure on `register(placement: ...)` gets called only if the user is already paying or if they begin paying.
6. If no paywall is configured, the feature gets executed immediately without any additional network calls.
Given the low cost nature of how register works, we strongly recommend registering **all core functionality** in order to remotely configure which features you want to gate – **without an app update**.
:::ios
```swift Swift
// on the welcome screen
func pressedSignUp() {
Superwall.shared.register(placement: "SignUp") {
navigation.beginOnboarding()
}
}
// in another view controller
func pressedWorkoutButton() {
Superwall.shared.register(placement: "StartWorkout") {
navigation.startWorkout()
}
}
```
```swift Objective-C
// on the welcome screen
- (void)pressedSignUp {
[[Superwall sharedInstance] registerWithPlacement:@"SignUp" params:nil handler:nil feature:^{
[navigation beginOnboarding];
}];
}
// In another view controller
- (void)pressedWorkoutButton {
[[Superwall sharedInstance] registerWithPlacement:@"StartWorkout" params:nil handler:nil feature:^{
[navigation startWorkout];
}];
}
```
:::
### Automatically Registered Placements
The SDK [automatically registers](/tracking-analytics) some internal placements which can be used to present paywalls:
### Register. Everything.
To provide your team with ultimate flexibility, we recommend registering *all* of your analytics events, even if you don't pass feature blocks through. This way you can retroactively add a paywall almost anywhere – **without an app update**!
If you're already set up with an analytics provider, you'll typically have an `Analytics.swift` singleton (or similar) to disperse all your events from. Here's how that file might look:
:::ios
```swift Swift
import SuperwallKit
import Mixpanel
import Firebase
final class Analytics {
static var shared = Analytics()
func track(
event: String,
properties: [String: Any]
) {
// Superwall
Superwall.shared.register(placement: event, params: properties)
// Firebase (just an example)
Firebase.Analytics.logEvent(event, parameters: properties)
// Mixpanel (just an example)
Mixpanel.mainInstance().track(event: event, properties: properties)
}
}
// And thus ...
Analytics.shared.track(
event: "workout_complete",
properties: ["total_workouts": 17]
)
// ... can now be turned into a paywall moment :)
```
:::
### Getting a presentation result
Use `getPresentationResult(forPlacement:params:)` when you need to ask the SDK what would happen when registering a placement — without actually showing a paywall. Superwall evaluates the placement and its audience filters then returns a `PresentationResult`. You can use this to adapt your app's behavior based on the outcome (such as showing a lock icon next to a pro feature if they aren't subscribed).
In short, this lets you peek at the outcome first and decide how your app should respond:
:::ios
```swift
Task {
let res = await Superwall.shared.getPresentationResult(forPlacement: "caffeineLogged")
switch res {
case .placementNotFound:
// The placement name isn’t on any campaign in the dashboard.
print("Superwall: Placement \"caffeineLogged\" not found ‑ double‑check spelling and dashboard setup.")
case .noAudienceMatch:
// The placement exists, but the user didn’t fall into any audience filters.
print("Superwall: No matching audience for this user — paywall skipped.")
case .paywall(let experiment):
// User qualifies and will see the paywall for this experiment.
print("Superwall: Showing paywall (experiment \(experiment.id)).")
case .holdout(let experiment):
// User is in the control/holdout group, so no paywall is shown.
print("Superwall: User assigned to holdout group for experiment \(experiment.id) — paywall withheld.")
case .paywallNotAvailable:
// A paywall *would* have been shown, but some error likely occurred (e.g., no VC to present from, networking, etc).
print("Superwall: Paywall not available — likely no internet, no presenting view controller, or another paywall is already visible.")
}
}
```

# Handling Deep Links
Source: https://superwall.com/docs/ios/quickstart/in-app-paywall-previews
undefined
1. Previewing paywalls on your device before going live.
2. Deep linking to specific [campaigns](/campaigns).
3. Web Checkout [Post-Checkout Redirecting](/web-checkout-post-checkout-redirecting)
## Setup
:::ios
There are two ways to deep link into your app: URL Schemes and Universal Links.
:::
### Adding a Custom URL Scheme
:::ios
Open **Xcode**. In your **info.plist**, add a row called **URL Types**. Expand the automatically created **Item 0**, and inside the **URL identifier** value field, type your **Bundle ID**, e.g., **com.superwall.Superwall-SwiftUI**. Add another row to **Item 0** called **URL Schemes** and set its **Item 0** to a URL scheme you'd like to use for your app, e.g., **exampleapp**. Your structure should look like this:

With this example, the app will open in response to a deep link with the format **exampleapp\://**. You can [view Apple's documentation](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app) to learn more about custom URL schemes.
:::
:::ios
### Adding a Universal Link
Only required for [Web Checkout](/web-checkout), otherwise you can skip this step.
Before configuring in your app, first [create](/web-checkout-creating-an-app) and [configure](/web-checkout-configuring-stripe-keys-and-settings) your Stripe app on the Superwall Dashboard.
#### Add a new capability in Xcode
Select your target in Xcode, then select the **Signing & Capabilities** tab. Click on the **+ Capability** button and select **Associated Domains**. This will add a new capability to your app.

#### Set the domain
Next, enter in the domain using the format `applinks:[your-web-checkout-url]`. This is the domain that Superwall will use to handle universal links. Your `your-web-checkout-url` value should match what's under the "Web Paywall Domain" section.

#### Testing
If your Stripe app's iOS Configuration is incomplete or incorrect, universal links **will not work**
You can verify that your universal links are working a few different ways. Keep in mind that it usually takes a few minutes for the associated domain file to propagate:
1. **Use Branch's online validator:** If you visit [branch.io's online validator](https://branch.io/resources/aasa-validator//) and enter in your web checkout URL, it'll run a similar check and provide the same output.
2. **Test opening a universal link:** If the validation passes from either of the two steps above, make sure visiting a universal link opens your app. Your link should be formatted as `https://[your web checkout link]/app-link/` — which is simply your web checkout link with `/app-link/` at the end. This is easiest to test on device, since you have to tap an actual link instead of visiting one directly in Safari or another browser. In the iOS simulator, adding the link in the Reminders app works too:

:::
### Handling Deep Links
:::ios
Depending on whether your app uses a SceneDelegate, AppDelegate, or is written in SwiftUI, there are different ways to tell Superwall that a deep link has been opened.
Be sure to click the tab that corresponds to your architecture:
```swift AppDelegate.swift
import SuperwallKit
class AppDelegate: UIResponder, UIApplicationDelegate {
// NOTE: if your app uses a SceneDelegate, this will NOT work!
func application(
_ application: UIApplication,
open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]
) -> Bool {
return Superwall.handleDeepLink(url)
}
func application(
_ application: UIApplication,
continue userActivity: NSUserActivity,
restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void
) -> Bool {
if userActivity.activityType == NSUserActivityTypeBrowsingWeb,
let url = userActivity.webpageURL {
return Superwall.handleDeepLink(url)
}
return false
}
}
```
```swift SceneDelegate.swift
import SuperwallKit
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
// for cold launches
func scene(
_ scene: UIScene,
willConnectTo session: UISceneSession,
options connectionOptions: UIScene.ConnectionOptions
) {
if let url = connectionOptions.urlContexts.first?.url {
Superwall.handleDeepLink(url)
}
else if let userActivity = connectionOptions.userActivities.first(where: { $0.activityType == NSUserActivityTypeBrowsingWeb }),
let url = userActivity.webpageURL {
Superwall.handleDeepLink(url)
}
}
// for when your app is already running
func scene(
_ scene: UIScene,
openURLContexts URLContexts: Set
) {
if let url = URLContexts.first?.url {
Superwall.handleDeepLink(url)
}
}
func scene(
_ scene: UIScene,
continue userActivity: NSUserActivity
) {
if userActivity.activityType == NSUserActivityTypeBrowsingWeb,
let url = userActivity.webpageURL {
Superwall.handleDeepLink(url)
}
}
}
```
```swift SwiftUI
import SuperwallKit
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
.onOpenURL { url in
Superwall.handleDeepLink(url)
}
}
}
}
```
```swift Objective-C
// In your SceneDelegate.m
#import "SceneDelegate.h"
@import SuperwallKit;
@interface SceneDelegate ()
@end
@implementation SceneDelegate
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions {
[self handleURLContexts:connectionOptions.URLContexts];
[self handleUserActivity:connectionOptions.userActivities.allObjects.firstObject];
}
- (void)scene:(UIScene *)scene openURLContexts:(NSSet *)URLContexts {
[self handleURLContexts:URLContexts];
}
- (void)scene:(UIScene *)scene continueUserActivity:(NSUserActivity *)userActivity {
[self handleUserActivity:userActivity];
}
#pragma mark - Deep linking
- (void)handleURLContexts:(NSSet *)URLContexts {
[URLContexts enumerateObjectsUsingBlock:^(UIOpenURLContext * _Nonnull context, BOOL * _Nonnull stop) {
[[Superwall sharedInstance] handleDeepLink:context.URL];
}];
}
- (void)handleUserActivity:(NSUserActivity *)userActivity {
if ([userActivity.activityType isEqualToString:NSUserActivityTypeBrowsingWeb] && userActivity.webpageURL) {
[[Superwall sharedInstance] handleDeepLink:userActivity.webpageURL];
}
}
@end
```
:::
## Previewing Paywalls
Next, build and run your app on your phone.
Then, head to the Superwall Dashboard. Click on **Settings** from the Dashboard panel on the left, then select **General**:

With the **General** tab selected, type your custom URL scheme, without slashes, into the **Apple Custom URL Scheme** field:

Next, open your paywall from the dashboard and click **Preview**. You'll see a QR code appear in a pop-up:


On your device, scan this QR code. You can do this via Apple's Camera app. This will take you to a paywall viewer within your app, where you can preview all your paywalls in different configurations.
## Using Deep Links to Present Paywalls
Deep links can also be used as a placement in a campaign to present paywalls. Simply add `deepLink_open` as an placement, and the URL parameters of the deep link can be used as parameters! You can also use custom placements for this purpose. [Read this doc](/presenting-paywalls-from-one-another) for examples of both.

# Setting User Attributes
Source: https://superwall.com/docs/ios/quickstart/setting-user-properties
Customize paywalls and target users by setting user attributes
By setting user attributes, you can display information about the user on the paywall. You can also define [audiences](/campaigns-audience) in a campaign to determine which paywall to show to a user, based on their user attributes.
You do this by passing a `[String: Any?]` dictionary of attributes to `Superwall.shared.setUserAttributes(_:)`:
:::ios
```swift Swift
let attributes: [String: Any] = [
"name": user.name,
"apnsToken": user.apnsTokenString,
"email": user.email,
"username": user.username,
"profilePic": user.profilePicUrl
]
Superwall.shared.setUserAttributes(attributes) // (merges existing attributes)
```
```swift Objective-C
NSDictionary *attributes = @{
@"name": user.name,
@"apnsToken": user.apnsTokenString,
@"email": user.email,
@"username": user.username,
@"profilePic": user.profilePicUrl
};
[[Superwall sharedInstance] setUserAttributes:attributes]; // (merges existing attributes)
```
:::
## Usage
This is a merge operation, such that if the existing user attributes dictionary
already has a value for a given property, the old value is overwritten. Other
existing properties will not be affected. To unset/delete a value, you can pass `nil`
for the value.
You can reference user attributes in [audience filters](/campaigns-audience) to help decide when to display your paywall. When you configure your paywall, you can also reference the user attributes in its text variables. For more information on how to that, see [Configuring a Paywall](/paywall-editor-overview).

# Tracking Subscription State
Source: https://superwall.com/docs/ios/quickstart/tracking-subscription-state
Monitor user subscription status in your iOS app
Superwall tracks the subscription state of a user for you. So, you don't need to add in extra logic for this. However, there are times in your app where you simply want to know if a user is on a paid plan or not. In your app's models, you might wish to set a flag representing whether or not a user is on a paid subscription:
```swift
@Observable
class UserData {
var isPaidUser: Bool = false
}
```
### Using subscription status
You can do this by observing the `subscriptionStatus` property on `Superwall.shared`. This property is an enum that represents the user's subscription status:
```swift
switch Superwall.shared.subscriptionStatus {
case .active(let entitlements):
logger.info("User has active entitlements: \(entitlements)")
userData.isPaidUser = true
case .inactive:
logger.info("User is free plan.")
userData.isPaidUser = false
case .unknown:
logger.info("User is inactive.")
userData.isPaidUser = false
}
```
One natural way to tie the logic of your model together with Superwall's subscription status is by having your own model conform to the [Superwall Delegate](/using-superwall-delegate):
```swift
@Observable
class UserData {
var isPaidUser: Bool = false
}
extension UserData: SuperwallDelegate {
// MARK: Superwall Delegate
func subscriptionStatusDidChange(from oldValue: SubscriptionStatus, to newValue: SubscriptionStatus) {
switch newValue {
case .active(_):
// If you're using more than one entitlement, you can check which one is active here.
// This example just assumes one is being used.
logger.info("User is pro plan.")
self.isPaidUser = true
case .inactive:
logger.info("User is free plan.")
self.isPaidUser = false
case .unknown:
logger.info("User is free plan.")
self.isPaidUser = false
}
}
}
```
Another shorthand way to check? The `isActive` flag, which returns true if any entitlement is active:
```swift
if Superwall.shared.subscriptionStatus.isActive {
userData.isPaidUser = true
}
```
:::ios
### Listening for entitlement changes in SwiftUI
For Swift based apps, you can also create a flexible custom modifier which would fire if any changes to a subscription state occur. Here's how:
```swift
import Foundation
import SuperwallKit
import SwiftUI
// MARK: - Notification Handling
extension NSNotification.Name {
static let entitlementDidChange = NSNotification.Name("entitlementDidChange")
}
extension NotificationCenter {
func entitlementChangedPublisher() -> NotificationCenter.Publisher {
return self.publisher(for: .entitlementDidChange)
}
}
// MARK: View Modifier
private struct EntitlementChangedModifier: ViewModifier {
// Or, change the `Bool` to `Set` if you want to know which entitlements are active.
// This example assumes you're only using one.
let handler: (Bool) -> ()
func body(content: Content) -> some View {
content
.onReceive(NotificationCenter.default.entitlementChangedPublisher(),
perform: { _ in
switch Superwall.shared.subscriptionStatus {
case .active(_):
handler(true)
case .inactive:
handler(false)
case .unknown:
handler(false)
}
})
}
}
// MARK: View Extensions
extension View {
func onEntitlementChanged(_ handler: @escaping (Bool) -> ()) -> some View {
self.modifier(EntitlementChangedModifier(handler: handler))
}
}
// Then, in any view, this modifier will fire when the subscription status changes
struct SomeView: View {
@State private var isPro: Bool = false
var body: some View {
VStack {
Text("User is pro: \(isPro ? "Yes" : "No")")
}
.onEntitlementChanged { isPro in
self.isPro = isPro
}
}
}
```
:::
### Superwall checks subscription status for you
Remember that the Superwall SDK uses its [audience filters](/campaigns-audience#matching-to-entitlements) for a similar purpose. You generally don't need to wrap your calls registering placements around `if` statements checking if a user is on a paid plan, like this:
```swift
// Unnecessary
if !Superwall.shared.subscriptionStatus.isActive {
Superwall.shared.register(placement: "campaign_trigger")
}
```
In your audience filters, you can specify whether or not the subscription state should be considered...

...which eliminates the needs for code like the above. This keeps you code base cleaner, and the responsibility of "Should this paywall show" within the Superwall campaign platform as it was designed.

# User Management
Source: https://superwall.com/docs/ios/quickstart/user-management
Identifying users and managing their identity in your iOS app
### Anonymous Users
Superwall automatically generates a random user ID that persists internally until the user deletes/reinstalls your app.
You can call `Superwall.shared.reset()` to reset this ID and clear any paywall assignments.
### Identified Users
If you use your own user management system, call `identify(userId:options:)` when you have a user's identity. This will alias your `userId` with the anonymous Superwall ID enabling us to load the user’s assigned paywalls.
Calling `Superwall.shared.reset()` will reset the on-device userId to a random ID and clear the paywall assignments.
:::ios
```swift Swift
// After retrieving a user's ID, e.g. from logging in or creating an account
Superwall.shared.identify(userId: user.id)
// When the user signs out
Superwall.shared.reset()
```
```swift Objective-C
// After retrieving a user's ID, e.g. from logging in or creating an account
[[Superwall sharedInstance] identifyWithUserId:user.id];
// When the user signs out
[[Superwall sharedInstance] resetWithCompletionHandler:completion];
```
:::
**Advanced Use Case**
You can supply an `IdentityOptions` object, whose property `restorePaywallAssignments` you can set to `true`. This tells the SDK to wait to restore paywall assignments from the server before presenting any paywalls. This should only be used in advanced use cases. If you expect users of your app to switch accounts or delete/reinstall a lot, you'd set this when users log in to an existing account.
### Best Practices for a Unique User ID
* Do NOT make your User IDs guessable – they are public facing.
* Do NOT set emails as User IDs – this isn't GDPR compliant.
* Do NOT set IDFA or DeviceIds as User IDs – these are device specific / easily rotated by the operating system.
* Do NOT hardcode strings as User IDs – this will cause every user to be treated as the same user by Superwall.
### Identifying users from App Store server events
On iOS, Superwall always supplies an [`appAccountToken`](https://developer.apple.com/documentation/storekit/product/purchaseoption/3749440-appaccounttoken) with every StoreKit 2 transaction:
| Scenario | Value used for `appAccountToken` |
| -------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| You’ve called `Superwall.shared.identify(userId:)` | The exact `userId` you passed |
| You *haven’t* called `identify` yet | The UUID automatically generated for the anonymous user (the **alias ID**), **without** the `$SuperwallAlias:` prefix |
Because the SDK falls back to the alias UUID, purchase notifications sent to your server always include a stable, unique identifier—even before the user signs in.\
Make sure any `userId` you pass to `identify` is a valid UUID string, as Apple requires `appAccountToken` values to follow the UUID format.

# PaywallPresentationHandler
Source: https://superwall.com/docs/ios/sdk-reference/PaywallPresentationHandler
A handler class that provides status updates for paywall presentation in register() calls.
Use this handler when you need fine-grained control over paywall events for a specific [`register()`](/ios/sdk-reference/register) call, rather than global events via [`SuperwallDelegate`](/ios/sdk-reference/SuperwallDelegate).
This handler is specific to the individual `register()` call. For global paywall events across your app, use [`SuperwallDelegate`](/ios/sdk-reference/SuperwallDelegate) instead.
## Purpose
Provides callbacks for paywall lifecycle events when using [`register()`](/ios/sdk-reference/register) with a specific handler instance.
## Signature
```swift
@objcMembers
public final class PaywallPresentationHandler: NSObject {
public func onPresent(_ handler: @escaping (PaywallInfo) -> Void)
public func onDismiss(_ handler: @escaping (PaywallInfo, PaywallResult) -> Void)
public func onSkip(_ handler: @escaping (PaywallSkippedReason) -> Void)
public func onError(_ handler: @escaping (Error) -> Void)
}
```
## Parameters
| Method | Parameters | Description |
| ----------- | ----------------------------------------------- | --------------------------------------------------------------- |
| `onPresent` | `handler: (PaywallInfo) -> Void` | Sets a handler called when the paywall is presented. |
| `onDismiss` | `handler: (PaywallInfo, PaywallResult) -> Void` | Sets a handler called when the paywall is dismissed. |
| `onSkip` | `handler: (PaywallSkippedReason) -> Void` | Sets a handler called when paywall presentation is skipped. |
| `onError` | `handler: (Error) -> Void` | Sets a handler called when an error occurs during presentation. |
## Returns / State
Each method returns `Void` and configures the handler for the specific paywall lifecycle event.
## Usage
Basic handler setup:
```swift
func registerFeatureWithHandler() {
let handler = PaywallPresentationHandler()
handler.onPresent { paywallInfo in
print("Paywall presented: \(paywallInfo.id)")
// Pause background tasks, analytics, etc.
}
handler.onDismiss { paywallInfo, result in
print("Paywall dismissed with result: \(result)")
switch result {
case .purchased:
showSuccessMessage()
case .cancelled:
showPromotionalOffer()
case .restored:
updateUIForActiveSubscription()
}
}
Superwall.shared.register(
placement: "premium_feature",
params: ["source": "feature_screen"],
handler: handler
) {
unlockPremiumFeature()
}
}
```
Handle skip and error cases:
```swift
let handler = PaywallPresentationHandler()
handler.onSkip { reason in
print("Paywall skipped: \(reason)")
switch reason {
case .userIsSubscribed:
proceedToFeature()
case .holdout:
proceedToFeature()
default:
break
}
}
handler.onError { error in
print("Paywall error: \(error)")
showErrorAlert(error)
}
```
Method chaining style:
```swift
func registerWithChaining() {
let handler = PaywallPresentationHandler()
.onPresent { _ in pauseVideo() }
.onDismiss { _, result in
resumeVideo()
handlePurchaseResult(result)
}
.onError { error in showAlert(error) }
Superwall.shared.register(
placement: "remove_ads",
handler: handler
) {
hideAdsFromUI()
}
}
```

# PurchaseController
Source: https://superwall.com/docs/ios/sdk-reference/PurchaseController
A protocol for handling Superwall's subscription-related logic with your own purchase implementation.
**This protocol is not required.** By default, Superwall handles all subscription-related logic automatically.
When implementing PurchaseController, you must manually update [`subscriptionStatus`](/ios/sdk-reference/subscriptionStatus) whenever the user's entitlements change.
## Purpose
Use this protocol only if you want complete control over purchase handling, such as when using RevenueCat or other third-party purchase frameworks.
## Signature
```swift
public protocol PurchaseController: AnyObject {
@MainActor
func purchase(product: StoreProduct) async -> PurchaseResult
@MainActor
func restorePurchases() async -> RestorationResult
}
```
## Parameters
| Method | Parameters | Return Type | Description |
| ------------------ | ----------------------- | ------------------- | -------------------------------------------------------------------------- |
| `purchase` | `product: StoreProduct` | `PurchaseResult` | Called when user initiates purchasing. Implement your purchase logic here. |
| `restorePurchases` | None | `RestorationResult` | Called when user initiates restore. Implement your restore logic here. |
## Returns / State
* `purchase()` returns a `PurchaseResult` (`.purchased`, `.failed(Error)`, or `.cancelled`)
* `restorePurchases()` returns a `RestorationResult` (`.restored` or `.failed(Error?)`)
When using a PurchaseController, you must also manage [`subscriptionStatus`](/ios/sdk-reference/subscriptionStatus) yourself.
## Usage
For implementation examples and detailed guidance, see [Using RevenueCat](/ios/guides/using-revenuecat).
This is commonly used with RevenueCat, StoreKit 2, or other third-party purchase frameworks where you want to maintain your existing purchase logic.

# SuperwallEvent
Source: https://superwall.com/docs/ios/sdk-reference/SuperwallEvent
An enum representing analytical events that are automatically tracked by Superwall.
These events provide comprehensive analytics about user behavior and paywall performance. Use them to track conversion funnels, user engagement, and revenue metrics in your analytics platform.
Common events to track for conversion analysis include `triggerFire`, `paywallOpen`, `transactionStart`, and `transactionComplete`.
## Purpose
Represents internal analytics events tracked by Superwall and sent to the [`SuperwallDelegate`](/ios/sdk-reference/SuperwallDelegate) for forwarding to your analytics platform.
## Signature
```swift
public enum SuperwallEvent {
// User lifecycle events
case firstSeen
case appOpen
case appLaunch
case appClose
case sessionStart
case identityAlias
case appInstall
// Deep linking
case deepLink(url: URL)
// Paywall events
case triggerFire(placementName: String, result: TriggerResult)
case paywallOpen(paywallInfo: PaywallInfo)
case paywallClose(paywallInfo: PaywallInfo)
case paywallDecline(paywallInfo: PaywallInfo)
// Transaction events

case transactionComplete(transaction: StoreTransaction?, product: StoreProduct, type: TransactionType, paywallInfo: PaywallInfo)
case transactionFail(error: TransactionError, paywallInfo: PaywallInfo)
case transactionAbandon(product: StoreProduct, paywallInfo: PaywallInfo)
case transactionRestore(restoreType: RestoreType, paywallInfo: PaywallInfo)
case transactionTimeout(paywallInfo: PaywallInfo)
// Subscription events
case subscriptionStart(product: StoreProduct, paywallInfo: PaywallInfo)
case freeTrialStart(product: StoreProduct, paywallInfo: PaywallInfo)
case subscriptionStatusDidChange
// System events
case deviceAttributes(attributes: [String: Any])
// And more...
}
```
## Parameters
Each event case contains associated values with relevant information for that event type. Common parameters include:
* `paywallInfo: PaywallInfo` - Information about the paywall
* `product: StoreProduct` - The product involved in transactions
* `url: URL` - Deep link URLs
* `attributes: [String: Any]` - Device or user attributes
## Returns / State
This is an enum that represents different event types. Events are received via [`SuperwallDelegate.handleSuperwallEvent(withInfo:)`](/ios/sdk-reference/SuperwallDelegate).
## Usage
These events are received via [`SuperwallDelegate.handleSuperwallEvent(withInfo:)`](/ios/sdk-reference/SuperwallDelegate) for forwarding to your analytics platform.

# SuperwallOptions
Source: https://superwall.com/docs/ios/sdk-reference/SuperwallOptions
A configuration class for customizing paywall appearance and behavior.
Only modify `networkEnvironment` if explicitly instructed by the Superwall team. Use `.release` (default) for production apps.
Use different `SuperwallOptions` configurations for debug and release builds to optimize logging and behavior for each environment.
The SDK automatically chooses StoreKit 2 on iOS 15+ and falls back to StoreKit 1 on older versions, but you can override this with `storeKitVersion`.
## Purpose
Configures various aspects of Superwall behavior including paywall presentation, networking, logging, and StoreKit version preferences.
## Signature
```swift
@objcMembers
public final class SuperwallOptions: NSObject {
public var paywalls: PaywallOptions
public var storeKitVersion: StoreKitVersion
public var networkEnvironment: NetworkEnvironment
public var logging: LoggingOptions
public var localeIdentifier: String?
}
```
## Parameters
| Property | Type | Description |
| -------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| `paywalls` | `PaywallOptions` | Configuration for paywall appearance and behavior. |
| `storeKitVersion` | `StoreKitVersion` | Preferred StoreKit version (`.storeKit1` or `.storeKit2`). Defaults to StoreKit 2 on iOS 15+. |
| `networkEnvironment` | `NetworkEnvironment` | Network environment (`.release`, `.releaseCandidate`, `.developer`, `.custom(String)`). **Use only if instructed by Superwall team.** |
| `logging` | `LoggingOptions` | Logging configuration including level and scopes. |
| `localeIdentifier` | `String?` | Override locale for paywall localization (e.g., "en\_GB"). |
## Returns / State
This is a configuration object used when calling [`configure()`](/ios/sdk-reference/configure).
## Usage
Basic options setup:
```swift
let options = SuperwallOptions()
// Configure paywall behavior
options.paywalls.shouldShowPurchaseFailureAlert = false
options.paywalls.shouldAutoShowPurchaseLoadingIndicator = true
options.paywalls.automaticallyDismiss = true
// Set StoreKit version preference
options.storeKitVersion = .storeKit2
// Configure logging
options.logging.level = .warn
options.logging.scopes = [.superwallCore, .paywallViewController]
// Set locale for testing
options.localeIdentifier = "en_GB"
// Use with configure
Superwall.configure(
apiKey: "pk_your_api_key",
options: options
)
```
PaywallOptions configuration:
```swift
let paywallOptions = PaywallOptions()
// Presentation behavior
paywallOptions.shouldShowPurchaseFailureAlert = false
paywallOptions.shouldAutoShowPurchaseLoadingIndicator = true
paywallOptions.automaticallyDismiss = true
// Transaction behavior
paywallOptions.transactionTimeout = 30.0 // seconds
paywallOptions.restoreFailedPurchaseAlert.title = "Restore Failed"
paywallOptions.restoreFailedPurchaseAlert.message = "Please try again"
// Product overrides
paywallOptions.overrideProductsByName = [
"primary": "produceID_to_replace_primary_product"
]
// Assign to main options
options.paywalls = paywallOptions
```
Logging configuration:
```swift
let loggingOptions = LoggingOptions()
loggingOptions.level = .debug
loggingOptions.scopes = [.all] // or specific scopes like [.superwallCore, .network]
options.logging = loggingOptions
```
Real-world example for production:
```swift
func configureSuperwallForProduction() {
let options = SuperwallOptions()
// Minimal logging for production
options.logging.level = .error
// Customize paywall behavior
options.paywalls.shouldShowPurchaseFailureAlert = true
options.paywalls.automaticallyDismiss = true
// Use StoreKit 2 for better performance on iOS 15+
options.storeKitVersion = .storeKit2
Superwall.configure(
apiKey: "pk_your_production_api_key",
options: options
)
}
```
Debug configuration for development:
```swift
func configureSuperwallForDebug() {
let options = SuperwallOptions()
// Verbose logging for debugging
options.logging.level = .debug
options.logging.scopes = [.all]
// Show detailed error alerts
options.paywalls.shouldShowPurchaseFailureAlert = true
// Test with specific locale
options.localeIdentifier = "es_ES"
Superwall.configure(
apiKey: "pk_your_test_api_key",
options: options
)
}
```

# getPaywall()
Source: https://superwall.com/docs/ios/sdk-reference/advanced/getPaywall
A function that retrieves a PaywallViewController for custom presentation.
You're responsible for the deallocation of the returned PaywallViewController. Do not present the same PaywallViewController in multiple places simultaneously.
The remotely configured presentation style is ignored when using this method. You must handle presentation styling programmatically.
## Purpose
Retrieves a PaywallViewController that you can present however you want, bypassing Superwall's automatic presentation logic.
## Signature
```swift
// Async/await version
@MainActor
public func getPaywall(
forPlacement placement: String,
params: [String: Any]? = nil,
paywallOverrides: PaywallOverrides? = nil,
delegate: PaywallViewControllerDelegate
) async throws -> PaywallViewController
// Completion handler version
public func getPaywall(
forPlacement placement: String,
params: [String: Any]? = nil,
paywallOverrides: PaywallOverrides? = nil,
delegate: PaywallViewControllerDelegate,
completion: @escaping (PaywallViewController?, PaywallSkippedReason?, Error?) -> Void
)
```
## Parameters
| Name | Type | Description |
| ------------------ | --------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- |
| `placement` | `String` | The name of the placement as defined on the Superwall dashboard. |
| `params` | `[String: Any]?` | Optional parameters to pass with your placement for audience filters. Keys beginning with `$` are reserved and will be dropped. Defaults to `nil`. |
| `paywallOverrides` | `PaywallOverrides?` | Optional overrides for products and presentation style. Defaults to `nil`. |
| `delegate` | `PaywallViewControllerDelegate` | A delegate to handle user interactions with the retrieved PaywallViewController. |
| `completion` | `@escaping (PaywallViewController?, PaywallSkippedReason?, Error?) -> Void` | Completion block for the callback version. |
## Returns / State
Returns a `PaywallViewController` that you can present. If presentation should be skipped, throws a `PaywallSkippedReason` error.
## Usage
Using async/await:
```swift
Task {
do {
let paywallViewController = try await Superwall.shared.getPaywall(
forPlacement: "premium_feature",
params: ["source": "settings"],
delegate: self
)
present(paywallViewController, animated: true)
} catch let reason as PaywallSkippedReason {
print("Paywall skipped: \(reason)")
} catch {
print("Error getting paywall: \(error)")
}
}
```
Using completion handler:
```swift
Superwall.shared.getPaywall(
forPlacement: "premium_feature",
delegate: self
) { paywall, skippedReason, error in
if let paywall = paywall {
present(paywall, animated: true)
} else if let reason = skippedReason {
print("Paywall skipped: \(reason)")
} else if let error = error {
print("Error: \(error)")
}
}
```

completion: (() -> Void)? = nil
) -> Superwall
```
## Parameters
| Name | Type | Description |
| -------------------- | --------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `apiKey` | `String` | Your Public API Key from the Superwall dashboard settings. |
| `purchaseController` | `PurchaseController?` | Optional object for handling all subscription-related logic yourself. If `nil`, Superwall handles subscription logic. Defaults to `nil`. |
| `options` | `SuperwallOptions?` | Optional configuration object for customizing paywall appearance and behavior. See [`SuperwallOptions`](/ios/sdk-reference/SuperwallOptions) for details. Defaults to `nil`. |
| `completion` | `(() -> Void)?` | Optional completion handler called when Superwall finishes configuring. Defaults to `nil`. |
## Returns / State
Returns the configured `Superwall` instance. The instance is also accessible via [`Superwall.shared`](/ios/sdk-reference/Superwall).

Basic configuration:
```swift
Superwall.configure(apiKey: "pk_your_api_key")
```
With custom options:
```swift
let options = SuperwallOptions()
options.paywalls.shouldShowPurchaseFailureAlert = false
Superwall.configure(
apiKey: "pk_your_api_key",
options: options
) {
print("Superwall configured successfully")
}
```
With custom purchase controller:
```swift
Superwall.configure(
apiKey: "pk_your_api_key",
purchaseController: MyPurchaseController()
)
```

# handleDeepLink()
Source: https://superwall.com/docs/ios/sdk-reference/handleDeepLink
A function that handles deep links and triggers paywalls based on configured campaigns.
Configure deep link campaigns on the Superwall dashboard by adding the `deepLink` event to a campaign trigger.
Deep link events are also tracked via [`SuperwallEvent.deepLink`](/ios/sdk-reference/SuperwallEvent) and sent to your [`SuperwallDelegate`](/ios/sdk-reference/SuperwallDelegate).
## Purpose
Processes a deep link URL and triggers any associated paywall campaigns configured on the Superwall dashboard.
## Signature
```swift
public func handleDeepLink(_ url: URL)
```
## Parameters
| Name | Type | Description |
| ----- | ----- | -------------------------------------------------- |
| `url` | `URL` | The deep link URL to process for paywall triggers. |
## Returns / State
This function returns `Void`. If the URL matches a campaign configured on the dashboard, it may trigger a paywall presentation.
## Usage
In your SceneDelegate or AppDelegate:
```swift
func scene(_ scene: UIScene, openURLContexts URLContexts: Set) {
guard let url = URLContexts.first?.url else { return }
// Handle the deep link with Superwall
Superwall.shared.handleDeepLink(url)
// Continue with your app's deep link handling
handleAppDeepLink(url)
}
```
iOS 13+ SceneDelegate:
```swift
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Handle deep link on app launch
if let url = connectionOptions.urlContexts.first?.url {
Superwall.shared.handleDeepLink(url)
handleAppDeepLink(url)
}
}
```
Legacy AppDelegate:
```swift
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
// Handle the deep link with Superwall
Superwall.shared.handleDeepLink(url)
// Continue with your app's deep link handling
return handleAppDeepLink(url)
}
```

# identify()
Source: https://superwall.com/docs/ios/sdk-reference/identify
A function that creates an account with Superwall by linking a userId to the automatically generated alias.
Call this as soon as you have a user ID, typically after login or when the user's identity becomes available.
## Purpose
Links a user ID to Superwall's automatically generated alias, creating an account for analytics and personalization.
## Signature
```swift
public func identify(
userId: String,
options: IdentityOptions? = nil
)
```
## Parameters
| Name | Type | Description |
| --------- | ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `userId` | `String` | Your user's unique identifier, as defined by your backend system. |
| `options` | `IdentityOptions?` | Optional configuration for identity behavior. Set `restorePaywallAssignments` to `true` to wait for paywall assignments from the server. Use only in advanced cases where users frequently switch accounts. Defaults to `nil`. |
## Returns / State
This function returns `Void`. After calling, [`isLoggedIn`](/ios/sdk-reference/userId) will return `true` and [`userId`](/ios/sdk-reference/userId) will return the provided user ID.
## Usage
Basic identification:
```swift
Superwall.shared.identify(userId: "user_12345")
```
With options for account switching scenarios:
```swift
let options = IdentityOptions()
options.restorePaywallAssignments = true
Superwall.shared.identify(
userId: "returning_user_67890",
options: options
)
```
Call as soon as you have a user ID:
```swift
func userDidLogin(user: User) {
Superwall.shared.identify(userId: user.id)
// Set additional user attributes
Superwall.shared.setUserAttributes([
"email": user.email,
"plan": user.subscriptionPlan,
"signUpDate": user.createdAt
])
}
```

# register()
Source: https://superwall.com/docs/ios/sdk-reference/register
A function that registers a placement that can be remotely configured to show a paywall and gate feature access.
## Purpose
Registers a placement so that when it's added to a campaign on the Superwall Dashboard, it can trigger a paywall and optionally gate access to a feature.
## Signature
```swift
public func register(
placement: String,
params: [String: Any]? = nil,
handler: PaywallPresentationHandler? = nil,
feature: @escaping () -> Void
)
```
```swift
public func register(
placement: String,
params: [String: Any]? = nil,
handler: PaywallPresentationHandler? = nil
)
```
## Parameters
| Name | Type | Description |
| ----------- | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `placement` | `String` | The name of the placement you wish to register. |
| `params` | `[String: Any]?` | Optional parameters to pass with your placement. These can be referenced within audience filters in your campaign. Keys beginning with `$` are reserved for Superwall and will be dropped. Arrays and dictionaries are currently unsupported and will be ignored. Defaults to `nil`. |
| `handler` | `PaywallPresentationHandler?` | A handler whose functions provide status updates for the paywall lifecycle. Defaults to `nil`. |
| `feature` | `(() -> Void)?` | An optional completion block representing the gated feature. It is executed based on the paywall's gating mode: called immediately for **Non-Gated**, called after the user subscribes or if already subscribed for **Gated**. |
## Returns / State
This function returns `Void`. If you supply a `feature` block, it will be executed according to the paywall's gating configuration, as described above.
## Usage
```swift
Superwall.shared.register(
placement: "premium_feature",
params: ["source": "onboarding"]
) {
// Code that unlocks the premium feature
openPremiumScreen()
}
```
```swift
Superwall.shared.register(
placement: "onboarding_complete",
params: ["source": "onboarding"],
handler: self
)
```

# setUserAttributes()
Source: https://superwall.com/docs/ios/sdk-reference/setUserAttributes
A function that sets user attributes for use in paywalls and analytics on the Superwall dashboard.
These attributes should not be used as a source of truth for sensitive information.
Keys beginning with `$` are reserved for Superwall internal use and will be ignored. Arrays and dictionaries are not supported as values.
## Purpose
Sets custom user attributes that can be used in paywall personalization, audience filters, and analytics on the Superwall dashboard.
## Signature
```swift
public func setUserAttributes(_ attributes: [String: Any?])
```
## Parameters
| Name | Type | Description |
| ------------ | ---------------- | ---------------------------------------------------------------------------------------------------------------- |
| `attributes` | `[String: Any?]` | A dictionary of custom attributes to store for the user. Values can be any JSON encodable value, URLs, or Dates. |
## Returns / State
This function returns `Void`. If an attribute already exists, its value will be overwritten while other attributes remain unchanged.
## Usage
Set multiple user attributes:
```swift
let attributes: [String: Any] = [
"name": "John Doe",
"email": "john@example.com",
"plan": "premium",
"signUpDate": Date(),
"profilePicUrl": URL(string: "https://example.com/pic.jpg")!,
"isVip": true,
"loginCount": 42
]
Superwall.shared.setUserAttributes(attributes)
```
Set individual attributes over time:
```swift
Superwall.shared.setUserAttributes(["lastActiveDate": Date()])
Superwall.shared.setUserAttributes(["featureUsageCount": 15])
```
Remove an attribute by setting it to nil:
```swift
Superwall.shared.setUserAttributes(["temporaryFlag": nil])
```
Real-world example after user updates profile:
```swift
func updateUserProfile(user: User) {
Superwall.shared.setUserAttributes([
"name": user.displayName,
"avatar": user.avatarURL,
"preferences": user.notificationPreferences,
"lastUpdated": Date()
])
}
```
Use these attributes in campaign audience filters on the Superwall dashboard to show targeted paywalls to specific user segments.

# subscriptionStatus
Source: https://superwall.com/docs/ios/sdk-reference/subscriptionStatus
A published property that indicates the subscription status of the user.
If you're using a custom [`PurchaseController`](/ios/sdk-reference/PurchaseController), you must update this property whenever the user's entitlements change.
You can also observe changes via the [`SuperwallDelegate`](/ios/sdk-reference/SuperwallDelegate) method `subscriptionStatusDidChange(from:to:)`.
## Purpose
Indicates the current subscription status of the user and can be observed for changes using Combine or SwiftUI.
## Signature
```swift
@Published
public var subscriptionStatus: SubscriptionStatus { get set }
```
## Parameters
This property accepts a `SubscriptionStatus` enum value:
* `.unknown` - Status is not yet determined
* `.active(Set)` - User has active entitlements (set of entitlement identifiers)
* `.inactive` - User has no active entitlements
## Returns / State
Returns the current `SubscriptionStatus`. When using a [`PurchaseController`](/ios/sdk-reference/PurchaseController), you must set this property yourself. Otherwise, Superwall manages it automatically.
## Usage
Set subscription status (when using PurchaseController):
```swift
Superwall.shared.subscriptionStatus = .active(["premium", "pro_features"])
Superwall.shared.subscriptionStatus = .inactive
```
Get current subscription status:
```swift
let status = Superwall.shared.subscriptionStatus
switch status {
case .unknown:
print("Subscription status unknown")
case .active(let entitlements):
print("User has active entitlements: \(entitlements)")
case .inactive:
print("User has no active subscription")
}
```
Observe changes with Combine:
```swift
import Combine
class ViewController: UIViewController {
private var cancellables = Set()
override func viewDidLoad() {
super.viewDidLoad()
Superwall.shared.$subscriptionStatus
.sink { [weak self] status in
self?.updateUI(for: status)
}
.store(in: &cancellables)
}
func updateUI(for status: SubscriptionStatus) {
switch status {
case .active:
showPremiumContent()
case .inactive:
showFreeContent()
case .unknown:
showLoadingState()
}
}
}
```
SwiftUI observation:
```swift
struct ContentView: View {
@StateObject var superwall = Superwall.shared
var body: some View {
VStack {
switch superwall.subscriptionStatus {
case .active(let entitlements):
Text("Premium user with: \(entitlements.joined(separator: ", "))")
case .inactive:
Text("Free user")
case .unknown:
Text("Loading...")
}
}
}
}
```

# userId
Source: https://superwall.com/docs/ios/sdk-reference/userId
A property on Superwall.shared that returns the current user's ID.
The anonymous user ID is automatically generated and persisted to disk, so it remains consistent across app launches until the user is identified.
## Purpose
Returns the current user's unique identifier, either from a previous call to [`identify()`](/ios/sdk-reference/identify) or an anonymous ID if not identified.
## Signature
```swift
// Accessed via Superwall.shared
public var userId: String { get }
```
## Parameters
This is a read-only computed property on the [`Superwall.shared`](/ios/sdk-reference/Superwall) instance with no parameters.
## Returns / State
Returns a `String` representing the user's ID. If [`identify()`](/ios/sdk-reference/identify) has been called, returns that user ID. Otherwise, returns an automatically generated anonymous user ID that is cached to disk.
## Usage
Get the current user ID:
```swift
let currentUserId = Superwall.shared.userId
print("User ID: \(currentUserId)")
```
Check if user is identified:
```swift
if Superwall.shared.isLoggedIn {
print("User is identified with ID: \(Superwall.shared.userId)")
} else {
print("User is anonymous with ID: \(Superwall.shared.userId)")
}
```
Example usage in analytics:
```swift
func trackAnalyticsEvent() {
let userId = Superwall.shared.userId
Analytics.track("feature_used", properties: [
"user_id": userId,
"timestamp": Date()
])
}
```
Example usage in custom logging:
```swift
func logError(_ error: Error) {
Logger.log("Error for user \(Superwall.shared.userId): \(error)")
}
```
