Back in the old Mac-OS days, it was possible to load a CODE

provided a mechanism for others to develop small "helper" features
that could be dynamically linked into the main applications.
These helpers usually get called with a pointer to some structure,
and return some value or values in a second structure. They could
not define globals (well, not in the normal sense, and were
conceptually a subroutine.
Is there any way to support this type of user customization with
Cocoa and Xcode?
They're called loadable bundles or plug-ins now:
