Retrieve randomly generated child ID from Firebase

Question

I have Firebase generating random keys for my records in a Swift app. How do I go about retrieving that key if I want to change a specific record? In my example below, I\'m mark

Answer 1

Following Tim's answer for Swift 3 and Firebase 4 I had to use the below

for task in snapshot.children {
            guard let taskSnapshot = task as? DataSnapshot else {
                continue
            }

            let id = taskSnapshot.key

Answer 2

To create a randomly generated key you need to use childByAutoId() (which I can't see in your example code).
This will return a Firebase reference you could use and which will return the key with it's .key property

var post1Ref = ref.childByAutoId()
post1Ref.setValue(post1)

var postId = post1Ref.key

See documentation here

Answer 3

An alternative to Ron's answer involves generating the key first and then using it to set value:

let autoId = databaseReference.childByAutoId().key
databaseReference.child(autoId).setValue(YOUR_VALUE)

Answer 4

tasksRef.observeSingleEventOfType(.Value, withBlock: { snapshot in
    for task in snapshot.children {
        guard let taskSnapshot = task as? FDataSnapshot else {
            continue
        }

        let id = task.key
        // do other things
    }
}
