Calling Auth.SignInWithWebUI results in nothing happening

Describe the bug

I have created a minimal swift app to test federated log in with Amplify. I have created a button that calls the Amplify.Auth.signInWithWebUI method. When I click the button, the method is successfully called, but no Web UI appears on the screen and no error is thrown - there appears to be no side affect to calling the method at all

Steps To Reproduce

Steps to reproduce the behavior:
1. Configure Amplify
2. Click login button
3. Observe... nothing

Minimal example:

Main app:

import Amplify
import SwiftUI
import AWSCognitoAuthPlugin


@main
struct SwiftOauthMinimalApp: App {
    init() {
        do {
            try Amplify.add(plugin: AWSCognitoAuthPlugin())
            try Amplify.configure()
            print("Successfully configured Amplify")
        } catch {
            print("Unable to configure Amplify")
            print("Error: \(error)")
        }
    }
    
    var body: some Scene {
        WindowGroup {
            ContentView()

        }
    }
}

ContentView:

import Amplify
import Combine
import SwiftUI

struct ContentView: View {

    var body: some View {
        Button("Log in") {
            if let windowScene = UIApplication.shared.connectedScenes.first
                as? UIWindowScene,
                let window = windowScene.windows.first
            {
                print("\(window)")
                Task { await signInWithWebUI(window: window) }
            } else {
                print("Failed to access main window.")
            }
        }
    }

}

func signInWithWebUI(window: UIWindow) async {
    do {
        let signInResult = try await Amplify.Auth.signInWithWebUI(for: .custom("Auth0"),
            presentationAnchor: window)
        if signInResult.isSignedIn {
            print("Sign in succeeded")
        }
    } catch let error as AuthError {
        print("Sign in failed \(error)")
    } catch {
        print("Unexpected error: \(error)")
    }
}

Hi @januaryblues, thanks for opening this issue. We will attempt to reproduce it and post any updates in here.

In the meantime, could you please share the verbose logs when you call signInWithWebUI? They might help us diagnose your issue.
You can enable verbose logging by doing this before Amplify.configure():

Amplify.Logging.logLevel = .verbose

Ok, I have this working now. It looks like it was my fault, I had the WebDomain property slightly wrong. So the problem was mine.

I guess some more helpful feedback from Amplify would be useful, rather than just not have the WebUI appear. But other than that I think my problem is solved. Thanks for the help! :)

Hi @januaryblues! I was just about to comment that based on the last log:

AWSCognitoAuthPlugin/ShowHostedUISignIn.swift Sending event SignInEvent(data: nil, id: "D9D78D98-8C60-4975-B6E1-EB6285BCEC61", eventType: AWSCognitoAuthPlugin.SignInEvent.EventType.throwAuthError(AWSCognitoAuthPlugin.SignInError.hostedUI(AWSCognitoAuthPlugin.HostedUIError.signInURI)), time: nil)

there was probably something wrong in your redirect URL. I'm happy to hear that was indeed the issue and that now everything works for you, and I apologize for not coming back to you sooner.

You're right that the lack of an error being thrown is something we need to address in our side, so we'll keep this issue open to track that work and to post further updates.

Thanks!
