There is something called NSTimer in swift which could solve your problem. I have given an example like how you can use it. Just customise it for your purpose.

var timer = NSTimer.scheduledTimerWithTimeInterval(1.0, 
                                                   target: self, 
                                                   selector: Selector("yourMethodToCall"), 
                                                   userInfo: nil, 
                                                   repeats: true)

Add this line to the place where you need to call your function repeatedly.

1. The 1.0 refers to 1 second.
2. Change the selector to call yourMethodName
3. repeats is set to true to call that function every second.

Try this out and let me know if your are stuck somewhere. Thanks.
