Apple Mach-o linker error after editing older project

Apple Mach-o linker error after editing older project

I've been asked to make changes to a project that was developed on an
older version of XCode. I'm using version 4.6.3 and when I compile the
project I get the Apple Mach-o linker error which appears to relate to all
of the Frameworks included in the project.

I've tried a number of solutions including making sure all of the .m files
were added to Compile Sources of Build Phases Tab under the Project
Settings. I also ensured the Architectures were all the same but I still
get the error and I'm not sure what to try next.
