Xcode Version Information

This is a place to record various bits of information pertaining to a release of Xcode, including the build number and versions of llvm-gcc and clang.

Adding new entries

First make sure the versions of your installed Xcode and Command Line Tools match each other! You can upgrade the Command Line Tools from the tab "Downloads" in the preferences window of Xcode.app.

Then run the following command to generate a new entry and copy it directly to your clipboard for pasting it into this wiki page:

echo -e "=== $(xcodebuild -version |head -n1) ===\n * '''Xcode''': $(xcodebuild -version |tail -1)\n * '''llvm-gcc''': $(llvm-gcc --version |head -1)\n * '''clang''': $(clang --version |head -n1)" |tee /dev/tty |pbcopy

The toolchain version of the Xcode releases are also ​documented on Wikipedia.
