Xcode 4.6.2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。

- Fixes an issue where the crash log database could grow very large.
- Additional bug fixes and stability improvements.
Included in Xcode 4.6:

- 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.
