How can I access a user-defined Xcode build setting?

Question

If I added a user-defined setting in my build configuration, how can I read that setting in my Objective-C code?

I have two files in my project, debug.plist

Your code can't read arbitrary build settings. You need to use preprocessor macros.

EDIT: For example, in the target settings for the Debug configuration, you could add DEBUGGING=1 in the Preprocessor Macros build setting, and not define DEBUGGING in the Release configuration. Then in your source code you could do things like:

#if DEBUGGING
  use this file
#else
  use the other one
#endif
