Xcode

Xcode is Apple’s integrated development environment for Mac OS X, and resembles a cross between the old NeXT Interface Builder and the even more ancient MPW.

If you’ve installed Xcode after the command-line tools (happened to me in Sonoma), do this:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Since Apple decided to move all useful command-line binaries inside the app bundle, you need to add the following to your .bashrc:

export PATH=$PATH:/Applications/Xcode.app/Contents/Developer/usr/bin
