As I recall, that discussion was not really about automated tools to do 
it, but just the logistics of physically copying code into Swarm.  
Anyway, the process of making a C function callable from Objective C is 
easy, even easier than C++.   You just call the C function.  Objective C 
is a superset of C. 

Most popular programming languages have some means to `reflect' on the 
methods inside their runtimes or processed by their compilers.  The task 
is how to read this data to tell the Objective C runtime what kinds of 
incoming calls it should recognize, and how to issue those calls to the 
foreign runtime (and to do all of this with minimum execution 
overhead).  Swarm implements two of these: Java and COM.
