I watched Apple's iPhone 6S Expo on YouTube with my iPhone6¹, and noticed the new functionality to navigate between apps by swiping from the side of the screen, and as I tried this, I noticed something happened: YouTube was using swipe-from-left to navigate to the previous section of the app.

What happens now? Obviously YouTube loses that great UX navigation medium to iOS. So the question becomes: is there a mutually UX-Friendly solution to allow both the OS and the Application to swipe from the edge of the screen for navigation? What possibilities exist fundamentally in the study of UX to solve this conflict between OS and Application?
