The code is very similar to the tutorials and documentation. The difference is I am using MVVM+RxSwift. Here it is:
final class SignInViewModel {
struct Input {
let emailText: DriverString
let passwordText: DriverString
let signInTapped: SignalVoid
let appleSignInTapped: SignalVoid
}
let openDashboardScreen: SignalSignInViewParam
init(handleSignIn: @escaping (String, String) - ObservableSignInViewParam,
handleAppleSignIn: @escaping (String) - ObservableSignInViewParam,
input: Input) {
let signInEvent = input.signInTapped
.asObservable()
.withLatestFrom(Observable.combineLatest(input.emailText.asObservable(),
input.passwordText.asObservable()))
.flatMapLatest { (arg) - ObservableSignInViewParam in
let (email, password) = arg
return handleSignIn(email, password)
}
if #available(iOS 13, *) {
let appleSignInEvent = input.appleSignInTapped
.compactMap { [weak self] in return self?.createAuthController() }
.flatMapLatest { (authController: ASAuthorizationController) - ObservableSignInViewParam in
return authController.rx
.didCompleteWithAuthorization /* The delegate control event using RxCocoa's DelegateProxy */
.compactMap { authorization in
guard let credential = authorization.credential as? ASAuthorizationAppleIDCredential,
let authCodeData = credential.authorizationCode,
let authCode = String(data: authCodeData, encoding: .utf8)
else { return nil }
return authCode
}
.flatMapLatest { (authCode) - ObservableSignInViewParam in
return handleAppleSignIn(authCode) /* Send auth code to server and will return SignInViewParam on success */
}
}
openDashboardScreen = Observable.merge(signInEvent, appleSignInEvent)
.asSignal(onErrorSignalWith: .never())
} else {
openDashboardScreen = signInEvent.asSignal(onErrorSignalWith: .never())
}
}
@available(iOS 13.0, *)
private func createAuthController() - ASAuthorizationController {
let appleIdProvider = ASAuthorizationAppleIDProvider()
let request = appleIdProvider.createRequest()
request.requestedScopes = [.email, .fullName]
let authController = ASAuthorizationController(authorizationRequests: [request])
authController.performRequests()
return authController
}
}
I tried using imperative instead of reactive like the tutorials, and it still stuck on the Apple ID password screen.
