Of course that only gets you as far as ObjC, not Swift, and I don't know if Apple is going to OpenSource it. Originally designed for NextStep and then OpenStep compatibility, I've heard they are now more-or-less Cocoa compatible, but I've not played with any of it in almost 2 decades.

OS X changed Display Postscript to Display PDF, and increased the general hardware requirements 1000 fold (NeXT could run in 8-16MB, now you need GB).ĭue to the close marriage of GCC and Objective C and NeXT, your best bet at running XCode natively under Linux would be to do a port (if you can get ahold of the source - good luck) utilizing the GNUStep libraries. Xcode Releases All downloads are hosted by Apple. sort of like an X Server, but with postscript commands. The rest of the OS involved ObjectiveC (under arrangements between Stepstone and Richard Stallman of GNU/GCC) with a GUI based on a technology called "Display Postscript". It may be BSD compatible in the programming API, but it is NOT BSD.
It was originally designed as a MicroKernel, but due to performance constraints, they eventually decided they needed to include the Unix portion of the API into the kernel itself and so a BSD-compatible "server" (originally intended to process requests for BSD-compatible kernel messages) was moved into the kernel, making it a Monolithic kernel. The NeXTStep OS utilizes the Mach kernel developed by CMU. But just to be precise, OSX is not based on BSD, it is an evolution of NeXTStep.
