Apple releases Xcode 5.1.1 update

Apple on Thursday released the latest update to Xcode 5.1, bringing fixes for reported bugs and overall stability improvements to the software development, debugging and testing tool.

Coming one week after Apple released golden master seed to developers,Xcode version 5.1.1 is now available for public consumption on the Mac App Store.

From the release notes:
Includes SDKs for OS X 10.9 Mavericks, OS X 10.8 Mountain Lion, and iOS 7.1.

  • Fixes an issue that would reposition the Interface Builder canvas unexpectedly.
  • Improves the reliability of Quick Look within the debugger.
  • Fixes an issue where test cases would report as failed when in fact they had passed.
  • Fixes a rare code generation issue in the LLVM compiler.
  • Includes additional bug fixes and stability improvements.

The improvements come on top of existing features released in Xcode 5.1, including Xcode IDE, LLVM compiler, Instruments, iOS Simulator, and the latest OS X and iOS SDKs.

According to the release notes, fixes have been made to the Compiler, Debugging, Xcode Server and Xcode Build System areas. Version 5.1.1 fixes a compiled code crash when targeting iOS 5.1.1, and when using ARC and C++. A compiler error after converting a project from SenTest to XCTest has been resolved, as has an issue when using the -fsanitize=undefined-trap -fsanitize-undefined-trap-on- error options. Compiler options logic has also been updated to allow “Enforce Strict Aliasing” to be set to off with the -Ofast flag.

The Xcode server would sometimes incorrectly claim that the version of OS X Server is incompatible, but that has been fixed in the GM. A fix in the Build System resolves a problem involving assertions when using the -parallelizeTargets xcodebuild option or the Xcode build setting.

The Debugger module has been updated to fix a crash with multiple debugging sessions, with quick look for UIImageView, and where some objects would not display in the quick look popover on the first try. Also resolved were some issues with the UIView quick look popover in the Xcode variables view.

Apple is deprecating SenTestingKit and OCUnit, as well as the ATS.framework as mentioned above. While still present in version 5.1.1, Apple warns that they will be removed from a future release of Xcode, and that code using OCUnit will generate warnings while being compiled. Developers will need to migrate SenTestingKit and OCUnit code to XCTest by using the “Convert to XCTest …” option under Refactor in the Edit menu.

ATS functionality will also be removed from future OS X releases, meaning developers must migrate ATS code (including (ATSUI) to CoreText. In v5.1.1, source code using ATS APIs will generate warnings while being compiled. “For 10.8,” Apple warns, “there will be no loss of functionality but there could be areas where performance will suffer.”
