Appending a list on Firebase Realtime Database swift

I am using Firebase realtime database to store users lists of locations. At the moment instead of an item being added to the user list in firebase, its replaced. How do I get there to be an appended list which is created as a user adds locations into the tableview? So I would want the structure of the data to be:

USER_ID PlaceName: locationA locationB locationC

Is that possible to do? here is my code so far:

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "LabelCell", for: indexPath)
    for place in storedPlaces {
        storedNames.append(place.name)
    }
    cell.textLabel?.text = storedNames[indexPath.row]

    let Pname: String = (cell.textLabel?.text!)!
    print(Pname)
     let PplaceID = "Hello"
    let post : [String: AnyObject] = ["storedName" : Pname as AnyObject, "placeID" : PplaceID as AnyObject]

    let databaseRef = FIRDatabase.database().reference()
    databaseRef.child("PlaceNames").child((user?.uid)!).setValue(post)



    return cell

I think what you want is to let firebase define the location node keys:

let databaseRef = FIRDatabase.database().reference()
databaseRef.child("PlaceNames").child((user?.uid)!)
locationRef = databaseRef.childByAutoId()
locationRef.setValue(post)

This will result in a Firebase structure:

PlaceName
  uid_0
    -YUisisokapoksa
       storedName: "some name"
       placeID: "some id"
    -YNisimaii990js
       storedName: "some name"
       placeID: "some id

There's some info on the Firebase Getting Started Guide about using childByAutoId - in the updating or deleting data section
