Both offer significant new features
Hot on the heels of the day's earlier release of OS X 10.8 Mountain Lion (Developer Preview 3), Apple has released a new beta of the forthcoming Safari 5.2 as well as a preview of programming tool Xcode 4.4, reports AppleInsider. Both updates bring noticeable new features to the programs, but both are only for developers and require an Apple Developer account to access. Safari gains SVG filters and other improvements, while Xcode now supports 3D documents.
Xcode 4.4 beta features a number of enhancements and improvements, including support for the 2011 C++ standard, new interface builder support for AppKit features, touchups to the Find Bar and Search Navigator, minor fixes to the source editor jump bar popup and integrated QuickHelp in code completion. Also included are new Objective-C language features, major improvements to the static analyzer and both a viewer and editor for 3D files as .DAE documents.
There are some known issues with the release, including possible difficulty obtaining earlier versions of Xcode from the App Store, and minor issues with linker and new load commands, DYLD_* variables and the network link conditioner. The company also notes scheme editing issues, and a need to authenticate each time for non-admin users debugging or running Instruments.
Users running the new Xcode in Mountain Lion DP3 will notice that ATS APIs suffer under the new OS because the ATS framework has been deprecated. Apple recommends developers replace all ATS code with CoreText, as ATS support will be removed in future OS X releases. The update also features an updated LLVM Compiler, version 4.0.
The Xcode 4.4 preview can only be run on either OS X Lion 10.7.3 or today's Mountain Lion DP3. Mountain Lion is scheduled to arrive later this summer, though a specific release date has not been announced.
