Technically there is nothing that prevents us from supporting Objective-C++, but the warning implementation will need to handle it correctly. Currently, it doesn't support lambda expressions and C++ exceptions from the top of my head. Probably there are more language constructs that can cause incorrect warnings. Long story short, it needs additional logic and testing.

Cheers!
