INTRODUCING IOS 8
by Apple described iOS 8 as “huge for developers. Massive for everyone else”. That’s a good way to start and understand what iOS 8 does. While 7 brought a fresh coat of paint for iOS, 8 overhauls the engine inside. In this sense, iOS 8 and 7 are two halves of a whole; with this release, the transition from the old Jobs/Forstall iOS to the new Cook/ Ive iOS is complete.
Not only does the new iOS bid goodbye to faux-leather, it opens iOS up to app co-operation and OS customizability. In a sense, iOS 7 was meant to look different to you, the end-user, while iOS 8 is geared to look different to the developer. You might not see much difference now when you upgrade to iOS 8, but you might when your app updates start to roll out.
