Apple on Friday issued to developers a golden master build of the upcoming Xcode 6.1.1 update, bringing bug fixes for Xcode Server, the Swift programming language and Interface Builder, among others. The Xcode 6.1.1 GM, labeled build 6A2006, concentrates on fixing bugs from the most recent Xcode 6.1 release, including common SourceKit crashes in Swift and general issues with Xcode Server.
Specifically, Apple resolved multiple issues causing crash events in Swift, as well as other coding bugs, while patching permission problems, crashes and SSH handling in Xcode Server. The GM also addresses an issue in Interface Builder that would prevent opening or compiling IB documents containing a slash in its image name.
Finally, the OCUnit and SenTestingKit framework were deprecated with Xcode 6.1.1 and will be completely removed from the software in a future release. Developers are encouraged to migrate to XCTest for Xcode testing.
Alongside Xcode 6.1.1, Apple released Command Line Tools Packages for OS X 10.9 Mavericks and OS X 10.10 Yosemite, enabling UNIX-style development from Terminal.
Developers can access the Xcode 6.1.1 GM — a 2.5GB download — and the Command Line Tools Package via Apple’s developer portal.

Apple today released a candidate golden master version of OS X Yosemite to developers, just over two weeks after releasing the eighth Developer Preview alongside the third public beta of the upcoming Mac operating system.

The latest update for developers, which arrives as Build 14A379a, can be downloaded from the Mac App Store and through Apple’s Mac Dev Center. Apple has also released Xcode 6.1 GM seed and a new version of OS X Server 4.0 developer preview.

OS X Yosemite brings a flatter, more modern look to OS X, with an emphasis on translucency and redesigned dock, windows, and more. It also includes a multitude of new features, such as improved integration with iOS 8 through Continuity, a new “Today” view in Notification Center that offers integration with third-party apps, a retooled Spotlight search with new data sources, and several new features for apps like Mail, Safari, and Messages.

Over the course of the beta testing period, each Developer Preview has added new features and refined the look and performance of OS X Yosemite, although changes have become less obvious in more recent builds as Apple begins finalizing Yosemite ahead of its public release, which is expected in late October.

The current build may or may not be a final version of OS X Yosemite, depending on the outcome of final testing. As an example, Apple last year seeded its planned golden master build to developers on October 3, although it did release a second golden master version a few weeks later just ahead of the public release on October 22.
