[BUG] NSLocalizedDescription contains generic message while com.stripe.lib:ErrorMessageKey contains an informative message

[netaiVia]

Summary

It looks like whenever we get invalid_bank_account_iban error in here stripeErrorMessage is not nil and the function doesn't add the correct value to NSLocalizedDescription. Instead of containing the The IBAN you entered is invalid. string it contains the generic message.

We want to display a relevant message to our users based on the error but NSLocalizedDescription doesn't give us any information

Code to reproduce

Call

        let sepaDebitParams = STPPaymentMethodSEPADebitParams()
        sepaDebitParams.iban = ibanField.text

        let billingDetails = STPPaymentMethodBillingDetails()
        billingDetails.name = nameField.text
        billingDetails.email = emailField.text

        let paymentIntentParams = STPPaymentIntentParams(clientSecret: paymentIntentClientSecret)

        paymentIntentParams.paymentMethodParams = STPPaymentMethodParams(sepaDebit: sepaDebitParams,
                                                                         billingDetails: billingDetails,
                                                                         metadata: nil)

        STPPaymentHandler.shared().confirmPayment(paymentIntentParams, with: self) { (handlerStatus, paymentIntent, error) in
            print(error)
        }

and the error we get is

Error Domain=com.stripe.lib Code=50 "There was an unexpected error -- try again in a few seconds" UserInfo={com.stripe.lib:ErrorMessageKey=The provided IBAN is invalid., com.stripe.lib:StripeErrorTypeKey=invalid_request_error, NSLocalizedDescription=There was an unexpected error -- try again in a few seconds, com.stripe.lib:StripeErrorCodeKey=invalid_bank_account_iban}
