Where are libc++ headers located on Mac OS X Mavericks?

Question

I'd like to take a look at the headers and want to know where they are.

Answer 1

After you install Xcode it's located here:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1

Mac OS X 10.9+ no longer uses GCC/libstdc++ but uses libc++ and Clang.

Update: After the XCode 6.0.1 update the headers are now located here:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1
