When you’re writing scripts in xcode you’ll need to know what environment variables xcode exposes.

Here’s how you can find them all:

-make a new empty xcode cocoa project
-add a new “run script build phase phase” to the app target
-add this as the script:

env > ENV

-build the project.

There will be file in the project directory called “ENV”, which lists all environment variables. Which comes in really handy as a reference.
