swift - Timer counts instantly instead of respecting interval -


im trying make countdown timer. works fine except timer not count @ regular intervals (1sec); instead counts way down instantly giving me 0 every time. did lot of search without luck. examples find show similar timeinterval parameter.

var timer = timer() var remainingtime = 120  @objc func timercount () {     if remainingtime > 0 {         while remainingtime > 0 {             remainingtime -= 1             timerlabel.text = string(remainingtime)             print(remainingtime)         }     } else {         timer.invalidate()     } }  @ibaction func pausebutton(_ sender: any) {     timer.invalidate() }  @ibaction func playbutton(_ sender: any) {     timer = timer.scheduledtimer(timeinterval: 1, target: self, selector: #selector(self.timercount), userinfo: nil, repeats: true) }

the reason code not working have put unnecessary while loop in timercount() method. don't need this. timer fire method after each time interval. @ first call while loop make remainingtime 0. why instantly getting 0 every time.

you need remove while loop.
