Alongside OS X Mavericks and iOS 7, Apple is offering developers a pre-release version of Xcode which includes the OS X 10.9 SDK and iOS 7 SDK beta.
Xcode 5 comes with a bunch of UI improvements, including more working space, a faster and more compact interface for Open Quickly, and a refined search navigator.
The new Xcode delivers an updated Automatic Configuration module, a new test navigator, and new test categories in the assistant editor, the ability to create bots to build and analyze archive projects on OS X Server, debugger improvements, and lots more.
iOS Developer Program or Mac Developer Program membership is required to use Xcode 5, and every programmer attempting to use it must have OS X 10.8 or above installed.
Xcode 5 does not run on earlier versions of Mac OS X and supports software development for iOS 7, OS X 10.9, and OS X 10.8. Instruments require OS X 10.8.4. Developers can grab the new Xcode on Apple’s site.
