Firebase Google LogIn Xcode11之后的Segue

Question

我在这方面是新手，我正在寻找一个解决方案，以进入一个新的视图控制器登录后与谷歌。我想，登录是有效的，但是3天后我没有成功。我想在登录后进入其他空白的视窗控制器。我尝试了许多解决方案，可以在stackoverflow和google文档中找到，但似乎没有适用于我的Xcode版本的文档。

这是我的AppDelegate：

import UIKit
import Firebase
import GoogleSignIn
import FirebaseUI

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {



    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

        FirebaseApp.configure()
        GIDSignIn.sharedInstance()?.clientID = FirebaseApp.app()?.options.clientID
        GIDSignIn.sharedInstance()?.delegate = self

        return true
    }

    // MARK: UISceneSession Lifecycle

    func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
        if let error = error {
            if (error as NSError).code == GIDSignInErrorCode.hasNoAuthInKeychain.rawValue {
              print("The user has not signed in before or they have since signed out.")
            } else {
              print("\(error.localizedDescription)")
            }
            return
          }
            let userId = user.userID                  // For client-side use only!
            let idToken = user.authentication.idToken // Safe to send to the server
            let fullName = user.profile.name
            let givenName = user.profile.givenName
            let familyName = user.profile.familyName
            let email = user.profile.email
                print(fullName)

        guard let authentication = user.authentication else { return }
        let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken, accessToken: authentication.accessToken)

        Auth.auth().signIn(with: credential) { (authResult, error) in
            if let error = error {
                print("firebase sign in error")
                print(error)
                return
            } else {
            print("user is signed in with Firebase")

            }

        }

    func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any])
      -> Bool {
      return GIDSignIn.sharedInstance().handle(url)
    }



    }

}

这是我的ViewController

import Firebase
import GoogleSignIn
import UIKit
import FirebaseAuth

class ViewController: UIViewController{


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        GIDSignIn.sharedInstance()?.presentingViewController = self
        GIDSignIn.sharedInstance()?.signIn()
        GIDSignIn.sharedInstance()?.restorePreviousSignIn()
        super.viewDidAppear(true)


        let gSignIn = GIDSignInButton(frame: CGRect(x: 0,y: 0, width: 230, height: 48))
        gSignIn.center = view.center
        view.addSubview(gSignIn)
    }

}

如果有人能帮上忙，我将非常感谢。

如下所示：

let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)
var vc: UIViewController?
vc = storyboard.instantiateViewController(withIdentifier: "signed")
window?.rootViewController = vc
window?.makeKeyAndVisible()
