"Not setting the user up to fail" is a central tenet of good design, and for all the talk Apple does about design, sometimes they need their feet held to the fire to walk the walk. I like the swipe-anywhere design for unlocking, but it's stupid to carry it over to the alarm, because it's so easy to perform by accident while fumbling around trying to initiate Snooze. What would have made sense for the alarm is to make tap-anywhere initiate Snooze, while swiping over the traditional "slider area" would remain the way to turn the alarm off.
They actually made the alarm app functionally worse in iOS 7. It's disappointing, as is the Music app no longer respecting album boundaries for playback and shuffle when you enter an album through Artists view, and then there's the huge amount of new scrolling necessary to navigate the new hybrid album/songs view they gave us.
