Released in tandem with the 10.7.2 update for OS X Lion customers, Xcode 4.2 is specifically targeted at Lion users. “This package installs the Xcode IDE, the Instruments analysis tool, iOS Simulator, and OS framework bundles in the form of Mac OS X SDKs and iOS SDKs,” Apple adds. Users can also access the Apple Developer site to download the goods.
“Xcode is the complete developer toolset for creating applications for Mac, iPhone, and iPad,” reads Apple’s description on the Mac App Store. Apple has released Xcode 4.2 as a free download to all developers and non-developers alike with support for OS X Lion and iOS 5, and SDKs for coding apps for either of the two platforms.
