As with the previous Xcode 5 release, the fifth Developer Preview comes with the usual fixes and performance buffs, though bugs still remain ahead of the software's public debut.
According to people familiar with the fifth Xcode 5 preview, Apple has done work on a new navigator and test categories for Testing, bot creation and management in Continuous Integration, as well as real-time CPU, energy use, iCloud and OpenGL data in Debugger.
In addition, Interface Builder gets iOS 7 support, while Source Control and Version Editor introduces a new workflow design. Finally, Compiler receives a new Auto Vectorizer tool. Xcode 5's user interface and experience has also been slightly tweaked.
Developers can download the current preview, with a more complete list of new assets, from Apple's Development Center.
