Using an NSTimer in Swift

Question

In this scenario, timerFunc() is never called. What am I missing?

class AppDelegate: NSObject, NSApplicationDelegate {

    var myTimer: NSTimer? = nil

i use a similar approach to Luke. Only a caveat for people who are "private methods" purists:

DO NOT make callback private in Swift.

If You write:

private func timerCallBack(timer: NSTimer){

..

you will get:

timerCallBack:]: unrecognized selector sent to instance... Terminating app due to uncaught exception 'NSInvalidArgumentException'
