In the session titled "What’s new in AdAttributionKit" at WWDC 2025, several new features and updates were introduced for AdAttributionKit. Here are some of the key highlights:
-
Overlapping Conversion Windows: You can now measure overlapping conversion windows in your app. This allows for more accurate tracking of conversions that occur simultaneously. You can configure this by setting the "Eligible for Ad Attribution Kit Overlapping Conversions" key in your app's Info.plist.
-
Configurable Attribution Windows: Advertisers can now specify their desired attribution window length in the Info.plist file. This flexibility allows for different configurations based on ad network and ad interaction type, such as click-through and view-through ads.
-
Postback Enhancements: New features have been added to help better consume and interpret postback data. This includes the ability to customize attribution rules and receive new geography data in postbacks, which can help measure the success of ad campaigns in different countries.
-
Testability Improvements: New testability features have been introduced, allowing developers to test their AdAttributionKit implementation earlier in the development lifecycle. This includes creating development postbacks directly in iOS settings and testing conversion value updates.
-
Re-engagement Support: With iOS 18.4, apps can now have multiple active re-engagement conversion windows simultaneously, and conversion tags can be used to specify which re-engagement conversion to update.
For more detailed information, you can refer to the session chapters such as Measure overlapping conversion windows, Customize attribution rules, and Test AdAttributionKit.
