Apple on Saturday released a minor update to its app-building software for OS X and iOS, Xcode -- now at version 4.6.1. The most important addition to the program is support for OS X 10.8.3, with a corresponding update to the OS X SDK. It also fixes two specific issues: one where ARC-enabled apps would not launch on Snow Leopard (OS X 10.6.x), and a performance regression issue in the Analyze operation. The update to the free app is available exclusively on the Mac App Store, where it has been located since v4.6.
