Always retain custom delegate implementations that you use in a your own custom iOS classes. Not doing so can cause your delegate to get garbage collected early and functionality not working as expected.
For example:
let applePayController: PKPaymentAuthorizationViewController
applePayController = PKPaymentAuthorizationViewController.alloc().initWithPaymentRequest(
paymentRequest
)
applePayController.delegate = PKPaymentAuthorizationViewControllerDelegateImpl.initWithOwner(
this
)
let applePayController: PKPaymentAuthorizationViewController
let applePayControllerDelegate: PKPaymentAuthorizationViewControllerDelegateImpl
applePayController = PKPaymentAuthorizationViewController.alloc().initWithPaymentRequest(
paymentRequest
)
applePayControllerDelegate = PKPaymentAuthorizationViewControllerDelegateImpl.initWithOwner(
this
)
applePayController.delegate = applePayControllerDelegate
