Adding delay between execution of two following lines

Question

I need to add delay between the execution of two lines in a(same) function. Is there is any favorable options to do this?

Note: I don\'t need two di

Answer 1

I have a couple of turn-based games where I need the AI to pause before taking its turn (and between steps in its turn). I'm sure there are other, more useful, situations where a delay is the best solution. In Swift:

        let delay = 2.0 * Double(NSEC_PER_SEC) 
        let time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay)) 
        dispatch_after(time, dispatch_get_main_queue()) { self.playerTapped(aiPlayView) }

I just came back here to see if the Objective-C calls were different.(I need to add this to that one, too.)
