In one of my projects I got reports of users having a view "locking" when they tried to swipe to the right, to see if there is a hamburger menu.
I was able to successfully reproduce this and is most likely caused by sending touches to both the pan gesture and the underlaying view. Which was is this case a UICollectionView. This caused the animation to start, but never finish. Causing a overlay over the current view, giving the impression of locking the whole app.
