In the session titled "What’s new in StoreKit and In-App Purchase" at WWDC 2024, it was announced that the original API for in-app purchases, including the unified receipt, is deprecated starting with iOS 18 and aligned OS releases. While existing apps using the original API will continue to function, they will not receive any enhancements or new features in future operating system releases. Developers are strongly encouraged to update their apps to use StoreKit 2, which offers improvements such as access to customer transaction history, subscription renewal information, and modern language features like the Swift Async/Await pattern. For more details, you can refer to the session What’s new in StoreKit and In-App Purchase (21:06).
