Create a class that implements the PaymentService interface.
Within this class, implement the pay method to initiate the payment process and request for payment with the type of order, and handle the payment result.

Swift

copy
final class PaymentService: IAPWalletPaymentServiceSignature, UIAlertViewDelegate {
