iOS why isn't a swipe handled by the notificationcenter?

a swipe is an event so?

Notifications aren't UI events. Notifications are meant to report that something changed but they aren't usually related to UI changes. Usually swipes are detected by gesture recognizers, which have a direct connection to the view that's been swiped.

Thanks again for your insights! I knew that UIGestureRecognizer was used but I wondered why.
