Issue with Firebase Authentication

Hi Rune,

OK, I have just been messing around with the UIKit version of this “Drop-In Auth UI” and in that version the Firebase frameworks have been added using cocoapods. You wont get access to the right frameworks using Swift Package Manager for the reasons I mentioned in my last post.

So, if you want to have a crack at getting the SwiftUI version going (FirebaseAuthDemo) using cocoapods you will have to have the following pods specified in your Podfile:

    pod 'Firebase/Auth'
    pod 'FirebaseUI/Auth'
    pod 'FirebaseUI/Email'

This is my ContentView (Note the import statement is different):

import SwiftUI
import FirebaseEmailAuthUI

struct ContentView: View {
    @Binding var loggedIn: Bool
    
    var body: some View {
        VStack {
            Text("Welcome")
            Button(action: {
                try! FUIAuth.defaultAuthUI()?.signOut()
                loggedIn = false
            }) {
                Text("Sign Out")
            }
        }
    }
}

My LaunchView (Also note the import statement):

import SwiftUI
import FirebaseEmailAuthUI

struct LaunchView: View {
    @State private var loggedIn = false
    @State private var showLoginForm = false

    var body: some View {
        if !loggedIn {
            Button {
                showLoginForm = true
            } label: {
                Text("Sign In")
            }
            .sheet(isPresented: $showLoginForm, onDismiss: checkLogin) {
                LoginForm()
            }
            .onAppear {
                checkLogin()
            }
        } else {
            ContentView(loggedIn: $loggedIn)
        }
    }

    func checkLogin() {
        loggedIn = FUIAuth.defaultAuthUI()?.auth?.currentUser != nil ? true : false
    }
}

My LoginForm (Again, the import statement):

import Foundation
import SwiftUI
import FirebaseEmailAuthUI

struct LoginForm: UIViewControllerRepresentable {

    func makeUIViewController(context: Context) -> UINavigationController {

        let authUI = FUIAuth.defaultAuthUI()
        guard authUI != nil else {
            return UINavigationController()
        }

        let providers = [FUIEmailAuth()]
        authUI!.providers = providers

        return authUI!.authViewController()
    }

    func updateUIViewController(_ uiViewController: UINavigationController, context: Context) {

    }
}

Don’t forget to add your GoogleService-Info.plist file and make sure it is named EXACTLY as:

GoogleService-Info.plist

Let me know how you go.
