I am following the sign-in instruction from Google https://firebase.google.com/docs/auth/ios/google-signin#swift_5
However, I am having issues with Swift code.
I kept getting this issue « Framework AppAuth not found ».
I pod install GoogleSignIn and it installs AppAuth. I am not sure what else to do.
Below is my code
import SwiftUI
import Firebase
import GoogleSignIn
struct LoginUIView: View {
@State var status = UserDefaults.standard.value(forKey: "status") as? Bool ?? false
var body: some View {
VStack{
if status{
Home()
}
else{
Login()
}
}.animation(.spring())
.onAppear {
NotificationCenter.default.addObserver(forName: NSNotification.Name("statusChange"), object: nil, queue: .main) { (_) in
let status = UserDefaults.standard.value(forKey: "status") as? Bool ?? false
self.status = status
}
}
}
}
struct LoginUIView_Previews: PreviewProvider {
static var previews: some View {
ContentView()

@State var user = ""

}.padding(.bottom, 15)
