Provided that the code does not use GNUstep-only libraries or APIs (such
as GNUstep-only APIs in Base or Gui), it should be possible to compile
any GNUstep application for macOS if you generate a new Xcode project.
You should use the native macOS APIs (Foundation and AppKit) or else the
application will not behave like other Mac apps.
Since it supported macOS a few years ago, before the architecture
change, what did the architecture change do to prevent it from being
compiled for arm64? Is there x86_64-specific assembly or violations of
the new security requirements for arm64? If the build is not working for
unknown reasons, you might want to generate a new Xcode project with the
existing source code.

The Oolite game (https://github.com/OoliteProject/oolite) was
originally developed on Mac but now only works on Windows and Linux
using GNUstep due to the Mac architecture change a few years ago. What
would be the best approach to port the application to modern Mac (with
regard to the Objective-C/GNUstep part)? For example, is it best to
try to use the Mac APIs directly or to compile GNUstep Base for Mac if
that's possible? Are there any gotchas or blockers to look out for?
Are there any examples of projects using GNUstep that work on modern
Mac as well as Windows and/or Linux?
