Firebase Retrieving Data in Swift

Question

I\'m trying to retrieve specific data from just the currently logged in user. My data in my database looks like this:

Answer 1

let ref = Database.database().reference().child("users/stephenwarren001@yahoo.com")


    ref.observeSingleEvent(of: .value, with: { (snap : DataSnapshot)  in

        print("\(String(describing:  snap.value))")


    }) { (err: Error) in


        print("\(err.localizedDescription)")

    }
