Saves me from pulling my hair out when trying to read the debugger console output with all the date,time and other crap that I never need. This solution works great when struggling with calculations especially when all you want is a simple number or flag as output. Plus not having to worry about removing all of the NSLog()’s for release builds is awesome. Thanks for the tips!

Symbols are either defined or not defined

-DDEBUG is correct.

@Ben: In my limited testing GCC_PREPROCESSOR_DEFINITIONS does seem to work with LLVM. Since the setting is specifically directed at the preprocessor that seems to be the more appropriate setting to use, per Apple’s document linked above. But there’s nothing wrong with using OTHER_CFLAGS.

Thanks Nick! Two questions:
1) will GCC_PREPROCESSOR_DEFINITIONS work with LLVM, if not is there an equivalent?
2) OTHER_CFLAGS seems to work just fine for this, is there a reason why you wouldn’t use it?
Thanks.

If you’re going to use GCC_PREPROCESSOR_DEFINITIONS instead of OTHER_CFLAGS,
make sure to use the form “DEBUG=1″ instead of “-DDEBUG=1″

@Richard: There are so many ways to accomplish almost the same thing in Xcode... I used OTHER_CFLAGS based on Apple's Technical Q&A QA1431. After reading the Xcode Build Settings document carefully, I realize that GCC_PREPROCESSOR_DEFINITIONS is a more specific way to define DEBUG, and is therefore preferred. Thanks for the tip!

The GCC_PREPROCESSOR_DEFINITIONS and GCC_PREPROCESSOR_DEFINITIONS_NOT_USED_IN_PRECOMPS build settings are a better choice than OTHER_CFLAGS.

All of these build settings are documented in:
