Behind the new look

Apple's iOS 7 is not only the world's first 64-bit mobile OS, it also sports a completely new look. Gone are much of the chrome and gloss that characterized the UI in iOS 6, replaced by brighter, cleaner, and simpler elements that give developers more screen real estate to work with.

The yang to iOS 7's yin, Xcode 5 sports major improvements under the hood, from faster compiling and support for 64-bit apps to new features that smooth development and ease debugging. Together, iOS 7 and Xcode 5 allow developers to build better, faster, and less buggy mobile apps.
