Xcode 4.6.1が来てたので、ソフトウェア・アップデート経由でインストールしました。
- Updates the OS X SDK to support OS X Mountain Lion version 10.8.3.
- Fixes an issue where ARC-enabled apps would not launch on OS X 10.6 Snow Leopard.
- Fixes a performance regression in the Analyze operation.
Included in Xcode 4.6:
- Includes SDKs for OS X 10.8 Mountain Lion and iOS 6.1.
- Code completion heuristics are more accurate, and use an optimized default data set.
- New compiler warnings help identify potential bugs when using ARC and weak references.
- C++11 support for ‘user defined literals’ and ‘unrestricted unions’ features.
- Debugger can inspect elements within NSArray or NSDictionary objects.
- Analyze now performs deeper cross-function static analysis of Objective-C and C++ code.
- The number of indexing passes is reduced due to improved dependency checking.
- Additional bug fixes and stability improvements.
