Firebase snapshot.key not returning actual key?

Question

I have a query that searches for a user based on user ID.

usersRef.queryOrderedByChild(\"email\").queryEqualToValue(email).observeEventType(.Value, withBloc         


        

Answer 1

When you run a query at a location, the result will be a list of the matching children. Even if there is only a single matching item, the result will be a list of one child.

You're printing the key of all resulting children. Since there is no single result, the SDK prints the key of the location/collection that you queried: users.

What you're likely looking for is to loop over the matching children and print their keys:

let query = usersRef.queryOrderedByChild("email").queryEqualToValue(email)
query.observeEventType(.Value, withBlock: { snapshot in
    for child in snapshot.children {
        print(child.key)
    }
})
