Firebase数据库setValue：或removeValue失败：permission_denied iOS(Firebase Database setValue: or removeValue failed: permission_denied iOS)

 我正在尝试将数据写入Firebase数据库，但按下保存的按钮时，我仍然收到以下错误消息。

 我试过的东西：我已经确保我的.read和.write规则在我的控制台中设置为true，重新连接了我的savedButtonPressed按钮，并将Firebase引用写入函数中，并在我的savedButtonPressed（）方法中调用它。 
 
 额外的资源这里是我正在遵循的教程。 https://youtu.be/F42CzqIBxHQ?t=4m14s 
 
var ref: FIRDatabaseReference?

override func viewDidLoad() {
    super.viewDidLoad()

    ref = FIRDatabase.database().reference()

}

@IBAction func saveButtonPressed() {
   // TODO: Post data to Firebase

    firebaseChild()
    print("********************************")
    print("********************************")

}

func firebaseChild () {
    ref?.child("Test").childByAutoId().setValue("Hello Firebase")

}

I'm trying to write data to Firebase Database but I keep receiving the following error when my saved button is pressed.

Things I've tried: I've made sure my .read and .write rules were set to true in my console, reconnected my savedButtonPressed button, and wrote the Firebase reference in a function and called it in my savedButtonPressed() method.
