Auth.auth().createUser(withEmail: emailTextField.text!, password: passwordTextField.text!, 完成: { (user: User?, error: Error?)

Question

有人可以帮忙吗？

@IBAction func singupBtn_TouchUpInside(_ sender: Any) {
        Auth.auth().createUser(withEmail: emailTextField.text!, password: passwordTextField.text!, completion: { (user: User?, error: Error?) in
            if error != nil {
                print(error!.localizedDescription)
                return
            }
            let ref = FIRDatabase.database().reference()
            let userReference = ref.child("users")
            // print(userReference.descrption()) : https
            let uid = user?.uid
            let newUserReference = userReference.child(uid!)
            newUserReference.setValue(["username": self.userNameTextField.text!, "email": self.emailTextField.text!])
            print("description: \(newUserReference.description())")
        })

我收到了这个错误消息

无法将类型“（用户？，错误？）->（）”的值转换为预期的参数类型“AuthDataResultCallback？” （又名'可选（）>'）

使用的参数不正确。您的“用户：用户？”正在产生错误。 试试：

Auth.auth().createUser(withEmail: email, password: password, completion: { (authResult?, error?) in
   guard let user = authResult?.user, error == nil else {
       print(error!.localizedDescription)
       return
   }
   // your code
}
