Developers enrolled with Apple’s annual programs are being handed a new version of Xcode, the Apple-developed digital toolset for iOS and OS X programming. Xcode 4.6.1 adds compatibility with the latest version of Mountain Lion, OS X 10.8.3.
According to the documentation dished out by Apple Inc., Xcode 4.6.1 “Updates the OS X SDK to support OS X Mountain Lion version 10.8.3.”
The new release further includes some fixes for an issue where ARC-enabled apps would not launch on OS X 10.6 Snow Leopard, as well as a performance regression in the Analyze operation.
Superseding Xcode 4.6, the new Xcode 4.6.1 includes the initial SDK updates for OS X 10.8 Mountain Lion and iOS 6.1, more accurate code completion heuristics, new compiler warnings, C++11 support for ‘user defined literals’ and ‘unrestricted unions’ features, and a lot more.
