How to handle timeout in queries with Firebase

Question

I noticed that if I execute a query in Firebase and the database server is not reachable, the callback waits just forever (or until the server is reachable again).

I would suggest simply using a thread?

Allow yourself to assign your call to Firebase from within a thread instance, then in the rare event that the write to Firebase takes too long you can just cancel the thread?

let thread = NSThread(target:self, selector:#selector(uploadToFirebase), object:nil)

. . .

func uploadToFirebase(data: Dictionary) {

    // Do what you need to here. Just an example

    db.collection("posts").document("some unique post id").setData([
        "name": "John",
        "likes": 0
    ]) { err in
        if let err = err {
            print("Error writing document: \(err)")
        } else {
            print("Document successfully written!")
        }
    }

}

Then just create a timer that cancels the thread if the timer fires. If not, just cancel the timer.
