While developers are likely already running the latest and greatest from Apple's Mac Dev Center to take advantage of iOS 6 beta and Mountain Lion beta SDKs, everyone else who is learning about development, building for fun, or simply wants a stable version of Xcode can find the latest release in the Mac App Store. Updated to take advantage of the MacBook Pro with Retina display, Xcode 4.4 also includes OS X 10.8 SDKs in concert with the release of Mountain Lion earlier this morning. (Later versions of Xcode 4.3 already offered support for iOS 5.1). Xcode 4.4 requires the latest version of Lion, 10.7.4, or Mountain Lion 10.8 to run.
