无法实现Firebase匿名身份验证

Question

我正尝试创建一个按钮，以匿名方式向Firebase中签名用户，接收回调，然后如果登录成功转换到下一个ViewController。非常新的编程，所以任何帮助表示赞赏：

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. 
    } 
}

希望这种帮助。 :)

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. 
    } 
}
