The most easy way is to save timestamp of game start using Date() and on game finish call the code like this:

let seconds = Date().timeIntervalSinse(startDate)

Constant "seconds" will contain number of seconds in Double format. If you want to check how much time the user spent in the app, the best place for startDate saving is applicationDidBecomeActive(_ application: UIApplication) is of your app delegate and for finish date - applicationWillResignActive(_ application: UIApplication)

You can use NSTimer for this purpose. Create a class variable totalTime

var totalTime = 0

Create a timer

let timer: NSTimer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: #selector(tick), userInfo: nil, repeats: true)

Then you can define your tick method as

func tick() {
    totalTime += 1
}

Don't forget to invalidate your timer when you are finished
