AFAIK, you can still use Objective-C and create apps for macOS, iOS, and iPadOS? The APIs previously used may not be available anymore.

I'm sure you can still use Objective-C, but MacRuby stopped being updated around 2011, and I don't know how well it'd support newer versions of OSX.

I dropped OSX long ago, so can't even try it out any more.

I wonder how much of the LLVM bits could be reused? I'm sure LLVM's changed a bunch in the last 15 years, too.

My understanding is that MacRuby relied on Apple's ill-fated attempts to migrate from reference counting to regular garbage collection. I would be surprised if GC still worked on modern arm64 macOS. RubyMotion later adopted ARC but then it's not really Ruby anymore.

Gees, I forgot about their move to Arm. Almost certainly wouldn't work out of the box any more.

I think you misunderstood the comment. They were referring to Ruby and accessing the APIs.
