I'm looking to create a precompiled header file, to avoid having to include the same debug and tracking libraries in every header in the project.
I've created a file called -Prefix.pch:
#ifdef __OBJC__
#import "Blah.h"
#import "Blarg.h"
#endif
and added it to the project. Is there anything more I'm supposed to do, or should things just work now (assuming I do a project clean and recompile)?

pch is a precompiled header. Precompiled headers were invented to make compiling faster. Rather than parsing the same header files over and over, these files get parsed once, ahead of time.
Configure Visual Studio to create precompiled headerschoose "All Configurations", then go to C/C++ -> Precompiled Headers, choose "Create Precompiled Header", make sure stdafx. h is the header file to use, and leave the rest to the default value.
Set the target's build settings as follows:
GCC_PRECOMPILE_PREFIX_HEADER=YES
GCC_PREFIX_HEADER="Prefix.pch"
Note that you can plop these keys in the Build Settings search field, if you prefer to use Xcode's UI for your build settings.
