title: Touch events are delayed near left screen edge on iOS 9 only. How to fix it?
body: <p>I am developing a keybaord extension for iOS. On iOS 9 the keys react imediatelly except for keys along left edge of the keyboard. Those react with around 0.2 second delay. The reason is that the touches are simply delivered with this delay to the <code>UIView</code> that is root view of my keyboard. On iOS 8 there is no such delay.</p>
  
  <p>My guess is that this delay is cause by some logic that is supposed to recognize gesture for opening "running apps screen". That is fine but the delay on a keyboard is unacceptable. Is there any way how to get those events without delay? Perhaps just setting <code>delaysTouchesBegan</code> to <code>false</code> on some <code>UIGestureRecognizer</code>?</p>
