What I mean by swipe gestures is that when you swipe from the very edge of the screen, it take you to the last video/homepage. Every app updated for iOS 7 has this built in.
Apps updated to iOS 7's SDK do not have to follow that guideline. People seem to forget for the last few years, very few apps followed Apple's app guidelines. They moved way past it, adding things like pull out menus, swiping navigation, etc. I'm not sure people should expect every app updated to iOS 7 to work exactly the same. It is just not going to happen.
