Firebase Authentication:Newly created user can't be saved in Firebase - ios

Question

I was registering users with Firebase, but newly created user can't be saved in Firebase though I've refreshed the Firebase Login & Auth tab.Could you help me fix it?
The code is here:
let saveAction = UIAlertAction(title: "Save", style: .Default) { (action:UIAlertAction) in
self.ref.createUser(self.textFieldLoginEmail.text, password: self.textFieldLoginPassword.text, withCompletionBlock: { (error:NSError!) in
if error == nil
{
self.ref.authUser(self.textFieldLoginEmail.text, password: self.textFieldLoginPassword.text, withCompletionBlock: { (error, auth) -> Void in
})
}
})
}

Try an figure out what is the error is when you try and log in, here an example for the use of the Firebase error log:
Data.ref.authUser(textFieldLoginEmail.text, password: textFieldLoginPassword.text, withCompletionBlock: { error, authData in
if error != nil {
var msg = ""
if let errorCode = FAuthenticationError(rawValue: error.code) {
switch (errorCode) {
case .UserDoesNotExist:
msg = "Invalid user name"
case .InvalidEmail:
msg = "Invalid email"
case .InvalidPassword:
msg = "Invalid password"
case .NetworkError:
msg = "we're sorry, network error has occurred, please login from the settings menu later"
default:
msg = "we're sorry, we encountered an error, please try again"
}
let alert = UIAlertController(title: "User Authentication error",
message: msg,
preferredStyle: .Alert)
let OKAction = UIAlertAction(title: "OK",
style: .Default) { (action: UIAlertAction!) -> Void in
if errorCode == .NetworkError {
self.performSegueWithIdentifier("ToMenuSegue", sender: self)
}
self.textFieldLoginPassword.text = ""
self.view.endEditing(true)
}
alert.addAction(OKAction)
self.presentViewController(alert, animated: true, completion: nil)
}
} else {
// Logged in
self.performSegueWithIdentifier("ToMenuSegue", sender: self)
}
})
