# paymentAuthorizationController(_:didSelectShippingMethod:handler:)

Tells the delegate that the user selected a shipping method.

## Declaration

```

```swift
@MainActor optional func paymentAuthorizationController(_ controller: PKPaymentAuthorizationController, didSelectShippingMethod shippingMethod: PKShippingMethod) async -> PKPaymentRequestShippingMethodUpdate
```

## Parameters

- `controller`: The payment authorization controller.
- `shippingMethod`: The selected shipping method. This parameter contains one of the shipping methods included in the payment request.
- `completion`: The completion handler to call with the updated payment summary items.

## Discussion

Discussion Use this method to update shipping costs based on the shipping address the user selected, as previously passed to the delegate in the paymentAuthorizationController(_:didSelectShippingContact:handler:) method. If the user didn’t select an address, use the prepopulated address on the payment request. When the system calls this method, you create a new array of PKPaymentSummaryItem objects that represent the updated cost including shipping. For more information on creating summary items, see the PKPaymentRequest class’s paymentSummaryItems property.
