I need to implement a smooth transition to another View using a timer.
For example, when I click on the start button and after 15 seconds pass, the automatic transition to another View takes place.

In start button action start a timer with an incrementing counter variable. In the timer execution block if the count reaches 15, invalidate the timer and navigate to next view controller
@objc func startBtnAction(_ sender: UIButton) {
var count = 0
let target = 15
Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { [weak self] timer in
self?.label.text = String(format: "%02d:%02d", count/60,count%60)
if count == target {
timer.invalidate()
self?.performSegue(withIdentifier: "NextScreen", sender: self)
} else {
count += 1
}
}
}

Why not just set the `timeInterval` to be 15 and not bother with the `count`? **EDIT:** I misread the question. – NRitH May 28 '19 at 17:57

@NRitH In timer execution block count is used to update label.text. Check [image](https://i.stack.imgur.com/UyzuW.png) in OP comment – RajeshKumar R May 28 '19 at 18:00
