iPhone - NSTimer not repeating after fire

Question

I am creating and firing a NSTimer with:

ncTimer = [NSTimer scheduledTimerWithTimeInterval:1.0
                                           target:sel         


        

Answer 1

I don't know why but Timer.scheduledTimer method is not working but Timer.init method worked.

self.timer = Timer.init(timeInterval: 10.0, repeats: true, block: { (timer) in
            print("\n--------------------TIMER FIRED--------------\n")
            self.checkForDownload()
        })
RunLoop.main.add(self.timer!, forMode: RunLoopMode.defaultRunLoopMode)
