I've created a new scheme, and I want to define a constant on that scheme, and on Run Script build phase, I want to execute a custom command. I don't have problems with adding a run script phase and execute a command. But I have trouble with the conditional. I'm effectively following this tutorial:

How do I define a variable only one a scheme, and read that variable on custom script in the if [ ... ] block?
There's a difference between Configurations (like "Debug" & "Release") and Schemes (which are more broad, specifying the target that's going to be built, the configuration that will be used to build it -- you can select a different configuration for running vs profiling vs archiving, and which tests get run).
So instead of trying to determine the scheme at build time (there used to be a SCHEME_NAME environment variable, that appears to be gone as of Xcode 5), what you should do is create a new configuration (instructions on how to do this can be found here) and then you can define any specific environment variables you wish.
