Please fix your question format first as it is really hard to read and understand what you are trying to do in your code.

If you want to get a specific item in the Firebase Database, this example might help you:

// somebody try this if we can have space in-between Heritage and point1
let myDatabaseRef = Database.database().reference(withPath: "Beacons/Heritage Point1")

myDatabaseRef.observe(.value) { (snap:DataSnapshot) in 

    // Do whatever you want with your snapshot here
    print(snap.value)
}
