1) Can we add Python or Ruby classes to an existing Objective-C
project? I can't find a sample that mixes languages. I tried adding
some .rb files to my project, but they don't seem to be loaded at
runtime. Is there a way to make this work (assuming mixing languages
is supported at all)?
It uses RubyCocoa, mainly written in Ruby but contains some ObjC
classes. You can download the source code from the site.
2) In the WWDC 2006 or 2007 slides there was a bullet about "Memory
management does not work" and the vocal comment was that this was
still being looked into. I didn't grasp the full consequences about
this - was it saying no garbage collection for Python/Ruby programs
at all? No garbage collection for mixed-language apps? Or just no GC
on the Objective-C side of a mixed app? And, what is the current
status of this rather important bullet?
Yes. Because it uses Python's or Ruby's GC.
About RubyCocoa, I'm not sure that it works well with ObjC 2.0 GC.
But we don't need ObjC 2.0 GC. Because Ruby's GC takes care of all
objects, both Ruby objects and Objc objects.
