title: Swift 3.0 How to add a child on a parent in firebase
body: <p>I want to create a new child for instance games; and then data with games that the user have for instance "bought"... The thing is that the precondition is that the user is signed in, I've managed to store the data for when a user is logged in... So now I want to create a new child under this specific user and save some data for this which I just can't get to work.</p>
  
  <pre><code>Database.database().reference().child(Auth.auth().currentUser!.uid).child("Games").updateChildValues(["game" : downloadURL])
  </code></pre>
