ios - 无法实现 Firebase 匿名身份验证

Question

我正在尝试创建一个按钮，让用户匿名登录到 Firebase，接收回调，然后如果登录成功则过渡到下一个 ViewController。对编程非常陌生，因此非常感谢您的帮助:

import UIKit
import FirebaseAuth

 class ViewController: UIViewController {


@IBAction func Auth(_ sender: Any) {
    FIRAuth.auth()?.signInAnonymously(completion: <#T##FIRAuthResultCallback?##FIRAuthResultCallback?##(FIRUser?, Error?) -> Void#>)

        //Receive callback showing completion or error, then navigate to next ViewController

}


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
  }
}

希望对您有所帮助。 :)

import UIKit
import FirebaseAuth

class ViewController: UIViewController {

    @IBAction func Auth(_ sender: Any) {
        FIRAuth.auth()?.signInAnonymously { (user, error) in
           if let error = error {
             print("Sign in failed:", error.localizedDescription)

           } else {
            print ("Signed in with uid:", user!.uid)
           }
        }
    }

    override func viewDidLoad() {
      super.viewDidLoad()
      // Do any additional setup after loading the view, typically from a  nib.
    }

    override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
    }
 }
