# paymentAuthorizationViewControllerDidFinish(_:)

Tells the delegate that payment authorization finished.

## Declaration

```swift
func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController)
```

## Parameters

- `controller`: The payment authorization view controller.

## Discussion

Discussion This delegate method is called every time a payment finishes. A payment may finish because authorization was completed in paymentAuthorizationViewController(_:didAuthorizePayment:handler:), because authorization timed out, or because the user canceled the payment. important: Make any needed payment-related updates to your app’s state in this delegate method, especially if the payment is canceled or times out. Also, be sure to call dismiss(completion:) on the payment authorization view controller.
