Question

How can I define a preprocessor macro when using xcodebuild?

I need to build my app using a bunch of different configurations, and I would like to do this using a shell script which runs xcodebuild a number of times with different preprocessor macros.

Answer 1

Cmd + I on the project to open the Info dialog. Then in the “Build” tab, find the “Preprocessor Macros” setting. Add the macros there.

… Where you can find the setting name is GCC_PREPROCESSOR_DEFINITIONS, so you could add

GCC_PREPROCESSOR_DEFINITIONS="foo=bar"

to the xcodebuild arguments.
