iOS 3.+ migration guide


Qonversion iOS SDK 3 contains significant changes in how the library is initialized. Before, you initialized Qonversion using the launch call:

Qonversion.launch(withKey: "projectKey")
[Qonversion launchWithKey:@"projectKey"];

Now, instead, you should create a Qonversion Configuration object and provide it to the initialization method as follows:

let configuration = Qonversion.Configuration(projectKey: "projectKey", launchMode: .subscriptionManagement)
QONConfiguration *configuration = [[QONConfiguration alloc] initWithProjectKey:@"projectKey" launchMode:QONLaunchModeSubscriptionManagement];
[Qonversion initWithConfig:configuration];

Note that now you should provide a concrete value from the Qonverion.LaunchMode enum, depending on which mode you use Qonversion. Also, we've renamed our modes to make them clearer for users:

After the initialization, you can access the Qonversion instance whenever you want as follows:

[Qonversion sharedInstance];

So you should replace all your Qonversion calls with the construction above.

Also, if you were using Qonversion.setDebugMode() for testing purposes, you should now call the setEnvironment(.sandbox) method of the Qonversion Config before calling Qonversion.initWithConfig().

let configuration = Qonversion.Configuration(projectKey: "projectKey", launchMode: .subscriptionManagement)
QONConfiguration *configuration = [[QONConfiguration alloc] initWithProjectKey:@"projectKey" launchMode:QONLaunchModeSubscriptionManagement];
[configuration setEnvironment:QONEnvironmentSandbox];
[Qonversion initWithConfig:configuration];

As no launch method is available anymore, you won't get QNLaunchResult as a result. The good news is that there are analogues for all the fields you might have been using from there:

  • for uid, call userInfo() and get the qonversionId field of the Qonversion.User object from the result,
  • for products call products(),
  • for offerings call offerings(),
  • for permissions, call checkEntitlements().


We are on the way to renaming permissions to entitlements as this naming suits more what it is used for. So, the following objects and methods were renamed in this release:

Version <3Version 3+

The Qonversion.Entitlement class contains the same information as the Qonversion.Permission with minor renaming.

  • permissionID was renamed to entitlementID,

There is no setUpdatedPurchasesListener method in Qonversion. You should provide UpdatedEntitlementsListener to Qonversion.Configuration during the initialization using the setEntitlementsUpdateListener method.
The exact change is made to the setPermissionsCacheLifetime method. Now you can set the required lifetime using the Qonversion.Configuration setEntitlementsCacheLifetime function while Qonversion initialization.

let configuration = Qonversion.Configuration(projectKey: "projectKey", launchMode: .subscriptionManagement)
QONConfiguration *configuration = [[QONConfiguration alloc] initWithProjectKey:@"projectKey" launchMode:QONLaunchModeSubscriptionManagement];
[configuration setEntitlementsCacheLifetime:QONEntitlementsCacheLifetimeThreeMonths];
[Qonversion initWithConfig:configuration];

Automation changes

We've also changed the way the Automations is used. As in Qonversion, you should use Automations via the shared instance. On the first access, it will be initialized and returned. Then the initialized instance will be used.


You should access the shared instance of Automations strictly after you initialize Qonversion.

[Qonversion initWithConfig:...];
[[QONAutomations sharedInstance] setDelegate:...];

Also, the methods for working with push notifications were moved from Qonversion to Automations, so if you were using the following methods:

  • setNotificationsToken,
  • handleNotification,
  • getNotificationCustomPayload
    make sure to make calls from the Automations instance instead of the Qonversion one.

Rest of the changes

Along with the changes described above, there are several technical improvements and other changes in the new major release:

  • the deprecated methods resetUser and setUserId were removed.
    resetUser was deprecated for a long time and did nothing, so there is nothing to replace this call with, remove the call if you were still using it for some reason. setUserId should be replaced with the setProperty call with .userID parameter.
  • the experiments method was removed - we are now working on a new design of A/B experiments;
  • the Qonversion.AttributionSource enum was renamed to Qonversion.AttributionProvider.
  • the checkTrialIntroEligibilityForProductIds method was shortened to checkTrialIntroEligibility;
  • added the new method userInfo, which returns the information about the current Qonversion user. Now it contains internal Qonversion and identity identifiers. The user info may be extended in future releases;
  • added new enum values - Qonversion.OfferingTag.Unknown and Qonversion.TrialDuration.Unknown, which are used when parsing fails.
  • all the classes and functions' namings were fixed for Swift;
  • all the class prefixes were changed from QN to QON for Objective-C.
