No other changes listed, currently for developers only
On Tuesday, Apple seeded a "Golden Master" release of Xcode 5.0.2 (build 5A2005) to developers that adds support for iOS 7.0.3, the current version of iOS. The GM comes with the full IDE, tools, frameworks and iOS Simulator, but no other changes were listed in the release notes. It also includes the SDKs for both iOS and OS X Mavericks. The final version is likely to be released soon, and may also address compatibility with iCloud Keychain, which arrived with 7.0.3.
The current version of Xcode, v5.0.1, was released alongside OS X Mavericks on October 22. The new GM seed is available to developers through Software Update or the Apple Developer Portal.
