## Discussion

Discussion Use this method to update shipping costs based on the shipping address selected by the user, as previously passed to the delegate in the paymentAuthorizationController(_:didSelectShippingContact:completion:) method. If no address has been selected, use the prepopulated address on the payment request. When this method is called, 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. note: The delegate receives no further callbacks except paymentAuthorizationControllerDidFinish(_:) until it has invoked the completion block.
