Firebase completion listeners in swift

Question

How do you execute a completion listener for firebase in swift? It says there are completion listers for SetValue and UpdateValue in the docs but there is no example.

Answer 1

An example of using completion handler for setValue in firebase is given below. Similarly you can use completion handler for methods.

    func saveJob(completion:(Bool)-> Void) {
    FIRDatabase.database().reference().child("Job").setValue(["Title":self.title!,"Detail":self.details!], withCompletionBlock: { (error, ref) in
        debugPrint("Completed")
        completion(true)
    })
}
