In Xcode, I know that you can get variables such as PROJECT_DIR to use in some situations, such as a run script build phase. I am wondering if it's possible to get the build type (i.e., Release or Debug). Any ideas?

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.
Here's a list of the environment variables. I think you might want CURRENT_VARIANT. See also BUILD_VARIANTS.
