Instead of Appdelegate, It is better to use it in a specific view controller in which you want screen light to be alive.

Swift 5.0 Version:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    UIApplication.shared.isIdleTimerDisabled = true
}
override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    UIApplication.shared.isIdleTimerDisabled = false
}
