    func timerRuns(addTimeValue: Int = 1) {
    if let timeLabelInt = Int(timeLabel.text!) {
        if timeLabelInt + addTimeValue > 0 {
            timeLabel.text = String(timeLabelInt + addTimeValue)
        }
    }
}

when I debug this function when I don't send a value to the parameter it equals to 106102873578432.. any idea? Thanks!

(Im calling this function from the Timer.scheduledTimer method)

    The timer callback is called with exactly one argument, and that is (a pointer to) the timer itself. See for example https://stackoverflow.com/questions/24889279/passing-parameters-to-a-method-called-by-nstimer-in-swift. – Martin R May 30 '17 at 18:58
  • ohhh, nice to know, so there is a way to ignore that pointer and use that default parameter? – Dudu Butbul May 30 '17 at 19:20
  • @DuduButbul Default parameter values are a static feature of Swift – the value expressions are simply inserted by the compiler at the call-site. There doesn't exist a `func timerRuns()` version of your function, so the Obj-C runtime cannot possibly call it (i.e it can't be dynamically called with the default parameter value). You'd need to add another overload for that. – Hamish May 30 '17 at 20:01
  • @Hamish so you suggest to add another function timerRuns without parameters? – Dudu Butbul May 30 '17 at 20:11
  • @DuduButbul And then have that one chain to `timerRuns(addTimeValue:)`, yup. – Hamish May 30 '17 at 20:15
  • @hamish I did it but when I call it from scheduledTimer it says `Ambiguous use of 'timerRuns'` – Dudu Butbul May 30 '17 at 20:17
  • @DuduButbul You'll need to disambiguate the selector – compare https://stackoverflow.com/q/35658334/2976878 – Hamish May 30 '17 at 20:26
  • @Hamish works for me, Thanks! – Dudu Butbul May 30 '17 at 20:53
