Experimental Flags

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:

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.
