import UIKit import AuthenticationServices class ViewController: UIViewController { @IBOutlet weak var btnAppleSignIn: UIButton! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. } @IBAction func appleSigninTapped(_ sender: Any) { let appleIDProvider = ASAuthorizationAppleIDProvider() let request = appleIDProvider.createRequest() request.requestedScopes = [.fullName, .email] let authorizationController = ASAuthorizationController(authorizationRequests: [request]) authorizationController.delegate = self authorizationController.presentationContextProvider = self authorizationController.performRequests() } } |
Step 4: Now, make extension to implement ASAuthorizationControllerDelegate, ASAuthorizationControllerPresentationContextProviding methods.

extension ViewController: ASAuthorizationControllerDelegate, ASAuthorizationControllerPresentationContextProviding { func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor { return self.view.window! } func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) { print(error.localizedDescription) } func authorizationController(controller: ASAuthorizationController, didCompleteWithAuthorization authorization: ASAuthorization) { print("Authorization Done") if let appleId = authorization.credential as? ASAuthorizationAppleIDCredential { let applId = appleId.user let firstName = appleId.fullName!.givenName let lastName = appleId.fullName!.familyName let email = appleId.email print("Apple Id \(applId)") print("Apple Id \(String(describing: firstName))") print("Apple Id \(String(describing: lastName))") print("Apple Id \(String(describing: email))") redirectFurther() } } func redirectFurther() { // Write code here to proceed further after login. } } |
You can run the app now and check the feature.
A button will be shown and when you click on the button it will open the popup with AppleId information, you can login and continue.
