May be final update before WWDC, builds on 4.6
Late on Monday, Apple released a minor update to its development environment software for the Mac, Xcode, which is used to build applications for both OS X and iOS. The new version, 4.6.2, improves LLDB performance for debugging Objective-C code, and fixes and issue where the crash log database could grow to very large sizes, along with the usual assortment of bug fixes and stability improvements. It builds on the previous update, released last month, that finally supported 10.8.3. The free updated version is available through the Mac App Store.
Version 4.6, a major update, was released in January and included a number of new features, including updated SDKs for Mountain Lion and iOS 6.1 and code-completion heuristics that were more accurate and utilized an optimized default data set among other features. The new update is likely to be the last before Apple's annual Worldwide Developer's Conference, which is expected to take place in San Francisco in early June.
Apple often introduces an all-new update to Xcode at the conference, particularly when a new version of OS X or iOS is expected to be previewed as is the case this year. The current Xcode requires OS X 10.7.4, with app submissions to the Mac or iOS App Stores requiring membership in the appropriate developer program, which costs $99 per year.
