How can I print to console from an xcconfig file?

Question

I'm trying to debug some internal paths within xcconfig files, and I'd love to be able to echo/print/put the paths to see exactly where they're pointing.

Googling "What language is xcconfig?" doesn't give much besides that it's a text file (aren't they all?)

It's looks bash-ish, but echo doesn't work, neither does put or print or println.

You can see all environment and custom variables in any 'Run script' under 'Build Phases'.

1. YourConfig.xcconfig:

MY_VALUE = 11.0

2. Then add 'Run Script' with 'Show environment variables in build log':

3. Build and look at your logs under 'Report Navigator':

4. Expand the log to see all variables:
