## Return Value

Return Value Return true to continue the transaction in your app.

## Discussion

Discussion Return false to defer or cancel the transaction. If you return false, you can continue the transaction later by manually adding the SKPayment payment to the SKPaymentQueue queue. Discussion The system calls this delegate method when the user starts an in-app purchase in the App Store, and the transaction continues in your app. Specifically, if your app is already installed, StoreKit calls this method automatically. If your app isn’t installed when the user starts the in-app purchase in the App Store, the user receives a notification when the app installation is complete. StoreKit calls this method when the user taps the notification. Otherwise, if the user opens the app manually, StoreKit calls this method only if they open the app soon after they initiate the purchase. important: To enable promoted in-app purchases, your app needs to use either PurchaseIntent (starting in iOS 16.4) or paymentQueue(_:shouldAddStorePayment:for:) (starting in iOS 11). Don’t use both at the same time. If necessary, use conditional compilation to identify the OS version the app is running in. For more information, see Running code on a specific platform or OS version. For more information, see Promoting In-App Purchases.
