Unable to merge two firebase arrays in Firebase Database - swift

Question

Hello I am relatively new to Swift/Firebase and I am struggling to merge two arrays so that the downloadURL is seen amongst both the name and the email fields. One function adds the name and the email through the button click the other is another function to save the URL. When I try and merge them I get this (as seen in the image below). Here is my code:
#IBAction func createAccountAction(_ sender: AnyObject) {
let Users = Database.database().reference().child("Users")
let userDictionary : NSDictionary = ["email" : emailTextField.text as String!, "Name": nameTextField.text!]
Users.childByAutoId().setValue(userDictionary) {
(error, ref) in
if self.emailTextField.text == "" {
let alertController = UIAlertController(title: "Error", message: "Please enter your email and password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
} else {
Auth.auth().createUser(withEmail: self.emailTextField.text!, password: self.passwordTextField.text!) { (user, error) in
if error == nil {
print("You have successfully signed up")
//Goes to the Setup page which lets the user take a photo for their profile picture and also chose a username
var imgData: NSData = NSData(data: UIImageJPEGRepresentation((self.profilePicture?.image)!, 0.8)!)
self.uploadProfileImageToFirebase(data: imgData)
let vc = self.storyboard?.instantiateViewController(withIdentifier: "ViewController") as! ViewController
self.present(vc, animated: true, completion: nil)
} else {
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}
}
}
func addImageURLToDatabase(uid:String, values:[String:AnyObject]){
let Users = Database.database().reference().child("Users")
let ref = Database.database().reference(fromURL: "https://example.firebaseio.com/")
Users.updateChildValues(values) { (error, ref) in
if(error != nil){
print(error)
return
}
self.parent?.dismiss(animated: true, completion: nil)
}
}

Something like this is what you want. I removed a few variables from your function but you can add them back. I just wanted to make sure the code compiles.
#IBAction func createAccountAction(_ sender: AnyObject) {
let usersRef = Database.database().reference().child("Users")
let userDictionary : NSDictionary = ["email" : emailTextField.text!, "Name": nameTextField.text!]
if emailTextField.text == "" {
let alertController = UIAlertController(title: "Error", message: "Please enter your email and password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
} else {
Auth.auth().createUser(withEmail: self.emailTextField.text ?? "", password: self.passwordTextField.text ?? "") { (result, error) in
if error != nil {
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
return
}
guard let user = result?.user else { return }
// HERE YOU SET THE VALUES
usersRef.child(user.uid).setValue(userDictionary, withCompletionBlock: { (error, ref) in
if error != nil { print(error); return }
self.addImageURLToDatabase(uid: user.uid, values: ["Put": "Your Values Here" as AnyObject])
})
}
}
}
func addImageURLToDatabase(uid:String, values:[String:AnyObject]){
let usersRef = Database.database().reference().child("Users").child(uid)
usersRef.updateChildValues(values) { (error, ref) in
if(error != nil){
print(error)
return
}
self.parent?.dismiss(animated: true, completion: nil)
}
}
