How can I add an #ifdef DEBUG to Xcode?

Question

I have some code in a project which should never be used in the release build, but is useful when testing. I\'d like to do something like this:

#ifdef DEBUG
             


        

Answer 1

In recent Xcode project templates there’s already a DEBUG=1 macro defined for the Debug build configuration (in the Preprocessor Macros section). You can test it using the #if preprocessor directive.

Answer 2

I usually add my -DDEBUG=1 to the OTHER_C_FLAGS section in my XCode 4 project's build settings.

And yes, they can even discriminate between Debug / Release / ADHOC / Store builds.
