Between architecture changes (PowerPC to x86 to x86-64 and next up ARM), and compiler changes (I doubt Objective-C code written for OS X 1.0 will compile on the latest XCode), breaking API changes, security changes, and even deprecating standards (can't use latest OpenGL, you gotta use Metal)... not really.

Depends on how complicated it was. I can assure you that your simple GUI still mostly works as those classes came from NeXT and aren’t going anywhere soon.
