Xcode 4 has a lot of cool new features.
One of my favorites is it’s ability to tell you when you introduced a bug in your code; the feature is similar to a spell check found in a word processor.
Usually, these cool tools are only available for Objective-C, but because of LLVM, this feature works on C++ as well.
And on the topic of C++, Xcode 4 will support C++0X… Holy cow!
