“无法转换类型的值” - Firebase Swift中的错误

I am trying to create a user in Firebase with an email & password and upon successful creation of the user record, I would go and update tree with additional attributes as child nodes of the user's UID. Here is what I have in code:

我正在尝试使用电子邮件和密码在Firebase中创建用户,并且在成功创建用户记录后,我将使用其他属性更新树作为用户UID的子节点。这是我在代码中的内容:

@IBAction func registerPressed(sender: AnyObject) {
        let connection = Firebase(url:"https://something.firebaseio.com")

        connection.createUser(self.emailTxtField.text, password: self.passwordTxtField.text,
            withValueCompletionBlock: { error, result in
                if error != nil {
                    // There was an error creating the account
                    print("Error Creating Account...Please try again")

                } else {
                    let uid = result["uid"] as? String
                    print("Successfully created user account with uid: \(uid)")

                    /*After creating the user, we want to update the tree with other attributes*/
                    let userAdditionalDetails = ["name": self.nameTxtField.text, "mobile": self.mobileTxtField.text, "username": self.usernameTxtField.text]
                    let usersRef = connection.childByAppendingPath("users")

                    let users = ["\(uid)": userAdditionalDetails]
                    usersRef.setValue(users)
                }
        })
    }

Although am not sure if the above will work or not (since this my first work with Firebase SDK), I am getting the following error:

虽然我不确定上述内容是否有效(因为这是我第一次使用Firebase SDK),但我收到以下错误:

cannot convert value of type “[String: [String : String?]]” to expected argument type "AnyObject!"

无法将“[String:[String:String?]]”类型的值转换为预期的参数类型“AnyObject!”

I am unable of course to build the project due to the above error being triggered at line:

由于在线触发上述错误,我当然无法构建项目:

                usersRef.setValue(users)

Any idea why this is happening and how to solve it?

知道为什么会这样,以及如何解决它?

Thanks in advance.

提前致谢。

Found the solution and just having it here for someone else's future reference:

找到解决方案,并将其放在此处供其他人未来参考:

@IBAction func registerPressed(sender: AnyObject) {
    let connection = Firebase(url:"https://something.firebaseio.com")

    connection.createUser(self.emailTxtField.text, password: self.passwordTxtField.text,
        withValueCompletionBlock: { error, result in
            if error != nil {
                // There was an error creating the account
                print("Error Creating Account...Please try again")

            } else {
                let uid = result["uid"] as? String
                print("Successfully created user account with uid: \(uid)")

                /*After creating the user, we want to update the tree with other attributes*/
                let userAdditionalDetails = ["name": "\(self.nameTxtField.text!)", "mobile": "\(self.mobileTxtField.text!)", "username": "\(self.usernameTxtField.text!)"]
                let usersRef = connection.childByAppendingPath("users")

                let users = ["\(uid)": userAdditionalDetails]
                usersRef.setValue(users)
            }
    })


}

The catch is that when initializing userAdditionalDetails, should include the outlets variables in string format. E.g.

问题是,在初始化userAdditionalDetails时,应该以字符串格式包含outlet变量。例如。

"username": "\(username.text!)"

This worked and all objects reflected correctly in backend.

这有效,所有对象在后端都能正确反映。

In the call to usersRef.setValue(users), the error message states that the parameter is expected to be of type AnyObject!. Therefore, you must cast users to be of type AnyObject!:

在对usersRef.setValue(users)的调用中,错误消息指出该参数应该是AnyObject!类型。因此,您必须将用户强制转换为AnyObject!:

let users = ["\(uid)": userAdditionalDetails]
usersRef.setValue(users as? AnyObject)
