Discussion

Use this function if you are not using the Offerings system to purchase a StoreProduct. If you are using the Offerings system, use purchase(package:completion:) instead.

From here Purchases will handle the purchase with StoreKit and call the PurchaseCompletedBlock.

If the purchase was successful there will be a StoreTransaction and a CustomerInfo.

If the purchase was not successful, there will be an NSError.

If the user cancelled, userCancelled will be true.
