StoreKit handles in-app purchases, subscriptions, and App Store transactions across iOS, macOS, tvOS, watchOS, and visionOS. You query the products you offer with SKProductsRequest and inspect the returned SKProduct and its SKProductDiscount and SKProductSubscriptionPeriod, then submit an SKPayment to the SKPaymentQueue and track each SKPaymentTransaction through its SKPaymentTransactionState by observing the queue. The framework also supports receipt refreshes through SKReceiptRefreshRequest, App Store review requests with SKStoreReviewController, promotional overlays via SKOverlay, and the SKAdNetwork types for measuring ad-driven installs.
