UISystemGateGestureRecognizer and delayed taps near bottom of screen

Question

What are the standard UISystemGestureGateGestureRecognizers installed on the top level UIView of an iOS app for?

My app consists of two vie

Answer 1

This delayed touches bothered me too. Just as an addition to what's said before, here's a simple fix:

override func viewDidAppear(_ animated: Bool) {
    let window = view.window!
    let gr0 = window.gestureRecognizers![0] as UIGestureRecognizer
    let gr1 = window.gestureRecognizers![1] as UIGestureRecognizer
    gr0.delaysTouchesBegan = false
    gr1.delaysTouchesBegan = false
}

no need to remove those gesture recognizers. just add this to the main view controller.
