NSTimer Function Not Being Called

Question

I am creating and attempting to use an NSTimer with the following code:

import Foundation

class TimerCallbacker {

    init() {
        NSTimer.scheduledTimerWithTimeInterval(0.4, target: self, selector: #selector(TimerCallbacker.timerDidFire(_:)), userInfo: nil, repeats: true)
    }

    @objc func timerDidFire(timer: NSTimer) {
        print("hi")
    }
}

let timerCallbacker = TimerCallbacker()

The program runs for a second without any console output and then ends, instead of the expected functionality of printing "hi" every second.

Have a look here for a proper integration. Your last line is misplaced. It is out of the class declaration but should be in there.

Be sure to enable the Apple NSTimer Library for Java Implementation through your Xcode CLI interface! Use the library in the following way:

let timer = new NSTimer().delay(2000, "hours");
