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.
They're not all documented. For example, you won't find ARCHIVE_PATH, MARKETING_VERSION (the version string set in Xcode) in Naaff's or smorgan's answer. These 2 are very common pieces of information someone would need! Here's a list of all of them I got: https://gist.github.com/ben-xD/c063b0ca2c33684de1eb379bb9d6405d
How I got them
I found the best way was to print them using set, I just wrote this including a method to list all the environment variables available.
Add this to your run script (either Archive post run script, or your build phases run script, etc.):
#!/bin/sh
exec > ${PROJECT_DIR}/environment_variables.log 2>&1
set
Look in environment_variables.log and you'll see them all.
