Stripe iOS didCreatePaymentResult never gets called - ios

Question

The problem seems simple, didCreatePaymentResult never gets called.
BUT, in my old sample project, taken from your iOS example for payment intent, that didCreatePaymentResult gets called every single time I create or select a card, here's the repo of the working project: https://github.com/glennposadas/stripe-example-ios-nodejs
BUT again, my main concern is my current project.
I use v19.2.0 in both of these projects, I even tried the v19.3.0.
I wanted to use Stripe Charge really, but I believe Stripe does not support Apple pay for that. So I have no choice but to use Stripe Payment Intent.
CoreService.swift (conforms to STPCustomerEphemeralKeyProvider)
extension CoreService: STPCustomerEphemeralKeyProvider {
func createCustomerKey(withAPIVersion apiVersion: String, completion: #escaping STPJSONResponseCompletionBlock) {
orderServiceProvider.request(.requestEphemeralKey(stripeAPIVersion: apiVersion)) { (result) in
switch result {
case let .success(response):
guard let json = ((try? JSONSerialization.jsonObject(with: response.data, options: []) as? [String : Any]) as [String : Any]??) else {
completion(nil, NSError(domain: "Error parsing stripe data", code: 300, userInfo: nil))
return
}
completion(json, nil)
default:
UIViewController.current()?.alert(title: "Error stripe", okayButtonTitle: "OK", withBlock: nil)
}
}
}
}
PaymentController.swift
class PaymentViewController: BaseViewController {
// MARK: - Properties
private var paymentContext: STPPaymentContext!
private let paymentConstantValue: Int = 3000
// MARK: - Functions
// MARK: Overrides
override func viewDidLoad() {
super.viewDidLoad()
self.setupStripe()
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.hideNavBar(animated: true)
}
#IBAction func creditCardButtonTapped(_ sender: Any) {
self.paymentContext.presentPaymentOptionsViewController()
}
private func setupStripe() {
let config = STPPaymentConfiguration.shared()
config.appleMerchantIdentifier = "merchant.com.gsample.app"
config.companyName = "Scoutd LLC"
config.requiredBillingAddressFields = .none
config.requiredShippingAddressFields = .none
config.additionalPaymentOptions = .applePay
let customerContext = STPCustomerContext(keyProvider: CoreService())
let paymentContext = STPPaymentContext(
customerContext: customerContext,
configuration: config,
theme: STPTheme.default()
)
let userInformation = STPUserInformation()
paymentContext.prefilledInformation = userInformation
paymentContext.paymentAmount = self.paymentConstantValue
paymentContext.paymentCurrency = "usd"
self.paymentContext = paymentContext
self.paymentContext.delegate = self
self.paymentContext.hostViewController = self
}
}
// MARK: - STPPaymentContextDelegate
extension PaymentViewController: STPPaymentContextDelegate {
func paymentContextDidChange(_ paymentContext: STPPaymentContext) {
print("paymentContextDidChange")
}
func paymentContext(_ paymentContext: STPPaymentContext, didFailToLoadWithError error: Error) {
// error alert....
}
func paymentContext(_ paymentContext: STPPaymentContext, didCreatePaymentResult paymentResult: STPPaymentResult, completion: #escaping STPPaymentStatusBlock) {
print("didCreatePaymentResult ✅")
}
func paymentContext(_ paymentContext: STPPaymentContext, didFinishWith status: STPPaymentStatus, error: Error?) {
switch status {
case .success:
// success
case .error:
// error alert....
default:
break
}
}
}

SOLVED! This should help engineers struggling with Stripe implementation in the future.
So in my case, I have two buttons:
Apple Pay
Credit card.
The absolute solution for me is handle the selectedPaymentOption of the paymentContext.
Scenarios:
If the apple pay button is tapped, present apple pay sheet and don't present add/select card UI of Stripe.
If the credit card button is tapped, don't present apple pay sheet and instead present select card.
Related to #2, call requestPayment() if there's a selected option.
Voila! The didCreatePaymentResult now gets invoked!
// MARK: IBActions
#IBAction func applePayButtonTapped(_ sender: Any) {
if self.paymentContext.selectedPaymentOption is STPApplePayPaymentOption {
self.paymentContext.requestPayment()
}
}
#IBAction func creditCardButtonTapped(_ sender: Any) {
if let selectedPaymentOption = self.paymentContext.selectedPaymentOption,
!(selectedPaymentOption is STPApplePayPaymentOption) {
self.paymentContext.requestPayment()
return
}
self.paymentContext.presentPaymentOptionsViewController()
}
