Has anybody here written an application that does the GUI stuff using Cocoa/Obj C, but does all of the real work in C++ code? I know it's possible to, for example, link a program that with both Fortran and C objects, but is it possible to do this with Obj C and C++ together? It must be since it would be silly to re-write a C++ code base just to get a native app going. I guess the questions are: is it possible to do (in principle), and will XCode handle it easily? I have no existing Obj-C code, so if this is possible, is there a good way of going about doing this without making coding style people freak out?
