iPhone - NSTimer not repeating after fire

Question

I am creating and firing a NSTimer with:

ncTimer = [NSTimer scheduledTimerWithTimeInterval:1.0
                                           target:sel         


        

Answer 1

Swift timer with closure:

    let timer = Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { _ in
         // Do whatever
    }
    timer.fire()
