Firebase Ios Swift身份验证问题

我的代码不能正常工作。我创建了google firebase身份验证。我的密码坏了

    @IBAction func loginClicked(_ sender: UlButton) {
      if let email = usernameText.text, let password = passwordText.text { 
         Auth.auth().signIn(withEmail: email, password: password) {authResult, error in 
            self.makeAlert(titleInput: "Error", messagelnput:"Error")
    }
    self.performSegue(withldentifier: "goToViewController", sender: nil) 
    }
}

然后我写了这个代码。当您在登录页面上输入错误的电子邮件和密码时，将显示错误消息。但它也会转到另一个页面（主页，ldentifier:“goToViewController”）。我不想这样做。当我输入错误的电子邮件和密码时，我只想显示错误消息

我该怎么做？

感谢您的帮助

您需要在firebase的关闭响应中添加

performsgue

 @IBAction func loginClicked(_ sender: UlButton) {
      if let email = usernameText.text, let password = passwordText.text { 
         Auth.auth().signIn(withEmail: email, password: password) {authResult, error in 
           if error == nil { 
              self.performSegue(withldentifier: "goToViewController", sender: nil) 
           }
           else { 
              self.makeAlert(titleInput: "Error", messagelnput:"Error") 
            } 
        }
    }
}
