Ios Firebase身份验证获胜'；我什么也没表现出来

点击登录时，firebase默认屏幕会出现，但不会显示其他内容。这是我的代码，来自这个。我似乎无法解决这个问题。我跳过了这一部分，以验证我的应用程序和firebase之间的链接是否正确设置，如教程所示，因为谷歌似乎已将其删除。。这可能是问题所在吗？我怎样才能确认一切都设置得很好？除此之外，不应该有任何东西，对吗

import UIKit
import FirebaseUI

class LoginVC: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    @IBAction func login(_ sender: UIButton) {
        // Create the default auth UI object
        let authUI = FUIAuth.defaultAuthUI()

        guard authUI != nil else {
            // Log error
            return
        }

        // Set ourselves as delegate
        authUI?.delegate = self

        // Get a reference to the auth View Controller
        let authViewController = authUI!.authViewController()

        // Show vc
        present(authViewController, animated: true, completion: nil)
    }
}

extension UIViewController: FUIAuthDelegate {
    public func authUI(_ authUI: FUIAuth, didSignInWith authDataResult: AuthDataResult?, error: Error?) {
        if error != nil {
            // log
            return
        }

        performSegue(withIdentifier: "UITabBarController", sender: self)
    }
}
