With iOS 11, users can browse in-app purchases directly on the App Store and start a purchase even before downloading your app. During the iOS 11 beta period, promoted in-app purchases are displayed on the App Store without the ability to buy. Starting this fall, your app must handle App Store transactions of promoted in-app purchases in order for your in-app purchases to be displayed on the App Store. Once the GM version of Xcode 9 is released, simply implement the new delegate method within SKPaymentTransactionObserver, rebuild your app, and submit for review. You can also customize which promoted in-app purchases a user sees on a specific device with the SKProductStorePromotionController API.
