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.
