Would I be able to keep in touch with some C++ work in the equivalent .m record? Will it compile? Assuming no, what changes would it be a good idea for me to do to compile it?
The easiest solution is to inform Xcode to compile everything as Objective C++ merely. Set your target on the settings to Compile Sources As to Objective C++ and recompile. After that use C++ or Objective C anywhere you want.
