I want to complete the addition of new payment method that I implemented in this SO question. This save and reuse stripe tutorial shows that cardParams and billingDetails need to be passed to STPPaymentMethodParams. How to I get the cardParams and billingDetails from STPPaymentOptionsViewController?
This is the code that produce the STPPaymentOptionsViewController and then display the STPAddCardViewController when add card button is pressed.
import Foundation
import SwiftUI
import Stripe
struct PaymentOptionsView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, STPPaymentOptionsViewControllerDelegate {
var control: PaymentOptionsView
init(_ control: PaymentOptionsView) {
self.control = control
}
// Implement required delegate methods here:
func paymentOptionsViewControllerDidCancel(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewControllerDidFinish(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewController(_ paymentOptionsViewController: STPPaymentOptionsViewController, didFailToLoadWithError error: Error) {
}
}
func makeUIViewController(context: UIViewControllerRepresentableContext<PaymentOptionsView>) -> STPPaymentOptionsViewController {
let config = STPPaymentConfiguration()
// config.requiredBillingAddressFields = .none
config.appleMerchantIdentifier = "dummy-merchant-id"
return STPPaymentOptionsViewController(configuration: config, theme: STPTheme(), apiAdapter: STPCustomerContext(keyProvider: MyAPIClient()), delegate: context.coordinator)
}
func updateUIViewController(_ uiViewController: STPPaymentOptionsViewController, context: UIViewControllerRepresentableContext<PaymentOptionsView>) { }
}
STPPaymentOptionsViewController by design only returns you a PaymentMethod and not the raw card details.
Since the STPPaymentOptionsViewControllerDelegate returns you a STPPaymentOption, you can cast it to a STPPaymentMethod and then get the billingDetails for that PaymentMethod.
In your didSelect() delegate method, you can cast it like:
if let paymentMethod = paymentOption as? STPPaymentMethod {
print(paymentMethod.stripeId)
}

Im trying to open New Contact screen in my SwiftUI app but Im not getting Save\Done button.I haven't seen anybody doing this I really don't know answer why as it seems easy at first. This is my current code.
struct ContactsVC: UIViewControllerRepresentable{
typealias UIViewControllerType = CNContactViewController
func makeUIViewController(context: Context) -> CNContactViewController {
let store = CNContactStore()
let con = CNContact()
let vc = CNContactViewController(forNewContact: con)
vc.contactStore = store
vc.delegate = context.coordinator
return vc
}
func updateUIViewController(_ uiViewController: CNContactViewController, context: Context) {
}
class Coordinator: NSObject,CNContactViewControllerDelegate,UINavigationControllerDelegate{
var parent: ContactsVC
init(_ parent: ContactsVC) {
self.parent = parent
}
func contactViewController(_ viewController: CNContactViewController, didCompleteWith contact: CNContact?) {
}
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
}
I have requested authorisation when sending contact now I want to add it.
I am using a UIViewControllerRepresentable Class in my SwiftUI like this:
struct CalendarDayView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
return Coordinator(self)
}
func makeUIViewController(context: Context) -> DayViewController {
let dayView = DayViewController()
dayView.delegate = context.coordinator
return dayView
}
func updateUIViewController(_ dayView: DayViewController, context: Context) {
dayView.delegate = context.coordinator
}
typealias UIViewControllerType = DayViewController
class Coordinator: NSObject, DayViewDelegate {
var parent: CalendarDayView
init(_ parent: CalendarDayView) {
self.parent = parent
}
func dayViewDidSelectEventView(_ eventView: EventView) {
guard let ckEvent = eventView.descriptor as? EKWrapper else { return }
let ekEvent = ckEvent.ekEvent
endEventEditing() // Cannot find 'endEventEditing' in scope
}
}
}
In the dayViewDidSelectEventView() function i need access to the endEventEditing() function, coming from the DayViewController Class. I already try to pass the parent to the Coordinator, but that doesn't helpful. I can't access the endEventEditing() func over the parent variable like this:
parent.endEventEditing() // Value of type 'CalendarDayView' has no member 'endEventEditing'
So is there a way to access the DayViewController Class, generated by the makeUIViewController func inside Coordinator?
Can i use/pass the dayView variable
let dayView = DayViewController()
to my Coordinator so i can use functions coming from this Controller?
You can inject it in coordinator's property (having it weak to avoid cross-references).
Here is a demo:
struct CalendarDayView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
return Coordinator(self)
}
func makeUIViewController(context: Context) -> DayViewController {
let dayView = DayViewController()
dayView.delegate = context.coordinator
context.coordinator.viewController = dayView // << inject !!
return dayView
}
func updateUIViewController(_ dayView: DayViewController, context: Context) {
dayView.delegate = context.coordinator
}
typealias UIViewControllerType = DayViewController
class Coordinator: NSObject, DayViewDelegate {
weak var viewController: DayViewController? // << declare here !!
var parent: CalendarDayView
init(_ parent: CalendarDayView) {
self.parent = parent
}
func dayViewDidSelectEventView(_ eventView: EventView) {
guard let ckEvent = eventView.descriptor as? EKWrapper else { return }
let ekEvent = ckEvent.ekEvent
viewController?.endEventEditing() // << call !!
}
}
}
I am trying to implement Stripe Add Payment Method in SwiftUI. So a user can add a payment method or select from listed. After many days of searching I was able to implement a working PaymentOptionsView. However, when add new card is clicked it does not display the STPAddCardViewController to enter new payment methods
Here is the code that display the payment option
import Foundation
import SwiftUI
import Stripe
struct PaymentOptionsView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, STPPaymentOptionsViewControllerDelegate {
var control: PaymentOptionsView
init(_ control: PaymentOptionsView) {
self.control = control
}
// Implement required delegate methods here:
func paymentOptionsViewControllerDidCancel(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewControllerDidFinish(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewController(_ paymentOptionsViewController: STPPaymentOptionsViewController, didFailToLoadWithError error: Error) {
}
}
func makeUIViewController(context: UIViewControllerRepresentableContext<PaymentOptionsView>) -> STPPaymentOptionsViewController {
let config = STPPaymentConfiguration()
// config.requiredBillingAddressFields = .none
config.appleMerchantIdentifier = "dummy-merchant-id"
return STPPaymentOptionsViewController(configuration: config, theme: STPTheme(), apiAdapter: STPCustomerContext(keyProvider: MyAPIClient()), delegate: context.coordinator)
}
func updateUIViewController(_ uiViewController: STPPaymentOptionsViewController, context: UIViewControllerRepresentableContext<PaymentOptionsView>) { }
}
and here is APIClient
class MyAPIClient: NSObject, STPCustomerEphemeralKeyProvider {
func createCustomerKey(withAPIVersion apiVersion: String, completion: #escaping STPJSONResponseCompletionBlock) {
let customerId = "cus_LoK4MNElrbzeVg"
let url = "https://us-central1-test-mmmm.cloudfunctions.net/app/createEphemeralKey"
AF.request(url, method: .post, parameters: [
"api_version": "2020-08-27",
"customerId": customerId,
])
.validate(statusCode: 200..<300)
.responseJSON { responseJSON in
switch responseJSON.result {
case .success(let json):
completion(json as? [String: AnyObject], nil)
case .failure(let error):
print("Error creating customer Key (retrieving ephemeral key) with Alamofire. See: MyAPIClient - func createCustomerKey")
completion(nil, error)
}
}
}
}
What am I doing wrong and How do I implement the add new card method?
This code actually works fine. I was initially presenting PaymentOptionsView through .sheet(isPresented: so it does not allowing transition to a new view when the add card button is pressed. When the PaymentOptionsView is presented as
.background( // add a hidden `NavigationLink` in the background
NavigationLink(destination: PaymentOptionsView(), isActive: $showPaymentSheet) {EmptyView()}
.hidden()
)
everythings works. when the add new card button is pressed, the view transition to STPAddCardViewController perfectly.
I have the following code taken directly from this blog. This code successfully displays the FirebaseUI with Google sign In, Apple sign In, and Email sign in when I place the SignInViewUI into my view.
Google and Apple sign in both function correctly. Email sign in does nothing when tapped.
import Firebase
import FirebaseUI
import SwiftUI
typealias AM = AuthManager
class AuthManager : NSObject{
static let shared = AuthManager()
var authViewController : UIViewController {
return MyAuthViewController(authUI: FUIAuth.defaultAuthUI()!)
}
init(withNavigationBar : Bool = false){
FirebaseApp.configure()
super.init()
self.setupProviders()
}
private func setupProviders(){
let authUI = FUIAuth.defaultAuthUI()!
let providers: [FUIAuthProvider] = [
FUIGoogleAuth.init(authUI: authUI),
FUIOAuth.appleAuthProvider(),
FUIEmailAuth()]
authUI.providers = providers
}
}
extension AuthManager {
// an optional handler closure for error handling
func signOut(onError handler : ((Error?) -> Void)? = nil ){
do {
try FUIAuth.defaultAuthUI()?.signOut()
if let handler = handler {
handler(nil)
}
}
catch (let err){
if let handler = handler {
handler(err)
}
}
}
func isSignedIn() -> Bool {
if let _ = Firebase.Auth.auth().currentUser{
return true
}
return false
}
}
extension AuthManager {
func setAuthDelegate(_ delegate : FUIAuthDelegate){
FUIAuth.defaultAuthUI()?.delegate = delegate
}
}
class MyAuthViewController : FUIAuthPickerViewController {
override func viewDidLoad() {
super.viewDidLoad()
let scrollView = view.subviews[0]
scrollView.backgroundColor = .clear
let contentView = scrollView.subviews[0]
contentView.backgroundColor = .clear
view.backgroundColor = .clear
}
}
struct SignInViewUI: UIViewControllerRepresentable {
func makeUIViewController(context: UIViewControllerRepresentableContext<SignInViewUI>) ->
UIViewController {
return AM.shared.authViewController
}
func updateUIViewController(_ uiViewController: UIViewController,
context: UIViewControllerRepresentableContext<SignInViewUI>) {
// empty
}
}
I believe this is something to do with a navigation controller being required for the Email sign in, based on the final comment on this GitHub issue.
Surrounding the SignInViewUI in a NavigationView allows the button to work.
Secondly, the FirebaseApp.configure() line must be removed from the AuthManager and placed into the AppDelegate application(_ application: UIApplication, didFinishLaunchingWithOptions ... method.
.sheet(isPresented: $showSheet) {
STPPaymentOptionsViewController()
}
I run this code hoping to present the Stripe Payment Options View Controller in my content view and I get this error:
Instance method sheet(isPresented:onDismiss:content:) requires that STPAddCardViewController conform to View
I also tried to wrap the view into a UIViewRepresentable like so:
struct PaymentOptionsView: UIViewRepresentable {
func makeUIView(context: Context) -> STPPaymentOptionsViewController {
let config = STPPaymentConfiguration()
config.additionalPaymentOptions = .default
config.requiredBillingAddressFields = .none
config.appleMerchantIdentifier = "dummy-merchant-id"
return STPPaymentOptionsViewController(configuration: config, e: STPTheme(), customerContext: STPCustomerContext(), delegate: self as! STPPaymentOptionsViewControllerDelegate)
}
}
Then I get the error:
Type CheckOut.PaymentOptionsView does not conform to protocol UIViewRepresentable.
Considering that STPPaymentOptionsViewController inherits from ViewController you need to use UIViewControllerRepresentable instead.
You also need to implement the required delegate methods for the STPPaymentOptionsViewControllerDelegate.
struct PaymentOptionsView: UIViewControllerRepresentable {
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
class Coordinator: NSObject, STPPaymentOptionsViewControllerDelegate {
var control: PaymentOptionsView
init(_ control: PaymentOptionsView) {
self.control = control
}
// Implement required delegate methods here:
func paymentOptionsViewControllerDidCancel(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewControllerDidFinish(_ paymentOptionsViewController: STPPaymentOptionsViewController) {
}
func paymentOptionsViewController(_ paymentOptionsViewController: STPPaymentOptionsViewController, didFailToLoadWithError error: Error) {
}
}
func makeUIViewController(context: UIViewControllerRepresentableContext<PaymentOptionsView>) -> STPPaymentOptionsViewController {
let config = STPPaymentConfiguration()
config.additionalPaymentOptions = .default
config.requiredBillingAddressFields = .none
config.appleMerchantIdentifier = "dummy-merchant-id"
return STPPaymentOptionsViewController(configuration: config, theme: STPTheme(), apiAdapter: STPCustomerContext(), delegate: context.coordinator)
}
func updateUIViewController(_ uiViewController: STPPaymentOptionsViewController, context: UIViewControllerRepresentableContext<PaymentOptionsView>) { }
}
Keep in mind you're also setting the delegate in the STPPaymentOptionsViewController incorrectly. You need to use context.coordinator rather than self as! STPPaymentOptionsViewControllerDelegate.
