I had a quick look at the implementation. You're not using the 
objc_msgSend_* family of functions correctly. That's one of the main 
reasons why extern(Objective-C) was implemented. I strongly recommend 
you adapting extern(Objective-C) instead. At least read the commit 
message [1] for the commit which implements extern(Objective-C). It 
explains how objc_msgSend_* works.

I can provide more detail if necessary.
