title: XCode: Preprocessor macros from host target not being found in unit tests
body: <p>In my target setup I have preprocessor macros that set some URLs I use in the my app.  I have some integration tests to test server API integrations we've done.  When I run the unit tests, these preprocessor macros are not found and hence the unit tests do not compile.  It is my understanding that preprocessor macros set up in the host target will be available when running the tests</p>
