I see, you're using LDC? Then I recommend you have a look at the
Objective-C bridge  I created. It has not been updated in a very long
time but I think you can use it as a base. Perhaps just update it for D2.
Actually I've skimmed it before and failed to understand if it allows to
subclass ObjC objects. If it doesn't then calling the runtime might
still be necessary.
The implementation that is currently in DMD head is a very limited
implementation that only supports calling instance methods. So no,
currently it's not possible to subclass Objective-C classes.
Not really a problem since class functions do not seem tricky like
Class methods work the same as instance methods. In Objective-C classes
are objects themselves.
I was also unsure if extern(Objective-C) helps with the runtime
functions themselves, or rather only dispatch to the right runtime
function obj_msgSend_*. Or both.
It will call a method in the same way as the Objective-C compiler would
do. That means calling obj_msgSend_*.
