#

Are you already using the completion handler and are trying to get the error message from inside that function?

junior crystal Apr 8, 2022, 9:01 PM

#

yes

#

func addCardViewController(_ addCardViewController: STPAddCardViewController, didCreatePaymentMethod paymentMethod: STPPaymentMethod, completion: @escaping STPErrorBlock) {
}

#

I can get paymentMethod after creating card but don't know to get the error if have

#

I found that a swift bug, but not sure what is correct way to handle the error now

@junior crystal can I ask you to share a bit more code/context?

#

Then I can ask my team for help (I don't know our iOS SDK)

junior crystal Apr 8, 2022, 9:13 PM

#

oh no worry

#

I can get error from another function

#

I just wanna know if I can get from above function

#

but seem there is a swift bug

            // so the customer can try a different card

        } else if let paymentIntent = paymentIntent {
            // check if PaymentIntent succeeded here, if so
            // dismiss Stripe's UI with line 22
            // and call delegate method's completion block with `nil` since no error occurred, everything went fine
