## Discussion

Discussion Use this method to restore finished transactions—that is, transactions for which you have already called finishTransaction(_:). You call this method in one of the following situations: To install purchases on additional devices To restore purchases for an application that the user deleted and reinstalled When you create a new product to be sold in your store, you choose whether that product can be restored or not. See the In-App Purchase Programming Guide for more information. The payment queue delivers a new transaction for each previously completed transaction that can be restored. Each transaction includes a copy of the original transaction. After the transactions are delivered, the payment queue calls the observer’s paymentQueueRestoreCompletedTransactionsFinished(_:) method. If an error occurred while restoring transactions, the observer will be notified through its paymentQueue(_:restoreCompletedTransactionsFailedWithError:) method. This method has no effect in the following situations: All transactions are unfinished. The user did not purchase anything that is restorable. You tried to restore items that are not restorable, such as a non-renewing subscription or a consumable product. Your app’s build version does not meet the guidelines for the CFBundleVersion key. important: If you are using the In-App Purchase API and managing transactions using the Transaction API, use currentEntitlements to determine which in-app purchases the customer is currently entitled to. The restoreCompletedTransactions() function doesn’t affect transactions in the Transaction API. In rare cases when a user suspects the app isn’t showing all the transactions, call sync() in response to an explicit user action, like tapping a button.
