Alongside the releases of fresh iOS 7 and Apple TV
betas, Apple has also issued a fifth Developer Preview
of Xcode 5 -- which offers some improvements and changes as well as the usual fixes and performance enhancements. The new build (5A11365y) continues to polish the Simulator and Instruments, makes slight tweaks to the user interface and overall experience, adds iOS 7 support to Interface Builder and brings a new Auto Vectorizer tool to Compiler among other changes. Though bugs remain, there are also some further changes in the new build.
Also in the latest beta, Source Control and Version Editor offer a new workflow -- while tweaking is apparent in test categories for Testing, along with Continuous Integration, and Debugger. The beta is available to developers accounts only through the Mac App Store and Software Update. The final version is expected to be available around the time of the release of OS X 10.9 Mavericks and iOS 7, speculated to be sometime in mid-September.
