Discussion
Use this method to update shipping costs based on the shipping address the user selected in a call to paymentAuthorizationViewController(_:didSelectShippingContact:handler:). If the user didn’t select an address, use the prepopulated address of 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.
