Sign In With Apple Cannot Connect With Firebase Backend - swift

Question

So I've used sign in with apple in my app to sign users in, an when they click on the button, the user's name, email and user's id all show up. Then when I open the terminal I see : Optional("The identity provider configuration is not found."). Again, in Firebase, I can see that the user is all set up.
Here is the Login View;
import SwiftUI
import AuthenticationServices
import FirebaseAuth
import CryptoKit
struct LoginView: View {
#EnvironmentObject var userAuth: UserAuth
#State var currentnonce: String?
private func randomNonceString(length: Int = 32) -> String {
precondition(length > 0)
let charset: [Character] =
Array("0123456789ABCDEFGHIJKLMNOPQRSTUVXYZabcdefghijklmnopqrstuvwxyz-._")
var result = ""
var remainingLength = length
while remainingLength > 0 {
let randoms: [UInt8] = (0 ..< 16).map { _ in
var random: UInt8 = 0
let errorCode = SecRandomCopyBytes(kSecRandomDefault, 1, &random)
if errorCode != errSecSuccess {
fatalError(
"Unable to generate nonce. SecRandomCopyBytes failed with OSStatus \(errorCode)"
)
}
return random
}
randoms.forEach { random in
if remainingLength == 0 {
return
}
if random < charset.count {
result.append(charset[Int(random)])
remainingLength -= 1
}
}
}
return result
}
private func sha256(_ input: String) -> String {
let inputData = Data(input.utf8)
let hashedData = SHA256.hash(data: inputData)
let hashString = hashedData.compactMap {
String(format: "%02x", $0)
}.joined()
return hashString
}
var body: some View {
NavigationView {
Group {
SignInWithAppleButton(
onRequest: { request in
let nonce = randomNonceString()
currentnonce = nonce
request.requestedScopes = [.fullName, .email]
request.nonce = sha256(nonce)
},
onCompletion: { result in
switch result {
case .success(let authResults):
switch authResults.credential {
case let appleIDCredential as ASAuthorizationAppleIDCredential:
guard let nonce = currentnonce else {
fatalError("Invalid state: A login callback was received, but no login request was sent.")
}
guard let appleIDToken = appleIDCredential.identityToken else {
fatalError("Invalid state: A login callback was received, but no login request was sent.")
}
guard let idTokenString = String(data: appleIDToken, encoding: .utf8) else {
print("Unable to serialize token string from data: \(appleIDToken.debugDescription)")
return
}
let credential = OAuthProvider.credential(withProviderID: "apple.com",idToken: idTokenString,rawNonce: nonce)
Auth.auth().signIn(with: credential) { (authResult, error) in
if (error != nil) {
// Error. If error.code == .MissingOrInvalidNonce, make sure
// you're sending the SHA256-hashed nonce as a hex string with
// your request to Apple.
print(error?.localizedDescription as Any)
return
}
print("signed in")
self.userAuth.login()
}
print("\(String(describing: Auth.auth().currentUser?.uid))")
default:
break
}
default:
break
}
NavigationLink("Login", destination: HomeView())
}
)
.frame(width: 200, height: 45, alignment: .center)
}
Text(self.loginStatusMessage)
.foregroundColor(.red)
}
.padding()
}
UserAuth;
import Foundation
class UserAuth: ObservableObject {
#Published var isLoggedIn: Bool = false
func login() {
self.isLoggedIn = true
}
}
The user gets added, but I don't think that the app recognizes that the user got added. It isn't letting the user go to the home screen. I've tried to add a navigation link, but that was not working.
