What's New in StoreKit

Session: What’s new in StoreKit and In-App Purchase

1. Core API Enhancements:

   • Transaction History: Starting in iOS 18, the transaction history APIs now include finished transactions for consumables, which were previously not accessible.
   • Deprecation of Original API: The original API for in-app purchases is deprecated starting with iOS 18. Existing apps will continue to work, but no new features or enhancements will be added to the legacy API. Developers are encouraged to update to StoreKit 2.

2. Modern Language Features:

   • Swift Async/Await: StoreKit 2 leverages modern Swift language features like async/await for tasks such as fetching product metadata, purchasing, and retrieving customer transaction history.
   • Back Deployment: Thanks to the back-deployed attribute in Swift, StoreKit 2 allows access to new App Store features even on devices with older operating systems.

3. Merchandising Using SwiftUI:

   • Subscription Store View: New features have been added to the subscription store view to enhance the merchandising of in-app purchases.
   • View Modifiers: New view modifiers like subscription promotional offer and Preferred subscription offer allow for more customization in displaying promotional offers and handling multiple eligible offers.

4. Testing Enhancements in Xcode:

   • StoreKit Testing: Numerous updates have been made to StoreKit testing in Xcode, including the ability to test privacy policies and license agreements locally.
   • Deferred Configuration: Developers can defer configuring products in App Store Connect until they have ensured the app behaves as expected, allowing them to focus on developing key features.
