We have an open bug on this, so no need to file one.

The issue is made worse by the fact all translation units that use the class only get the header file, so all of the debug info for this class is incomplete 99% of the time. There is only 1 version of the debug info for the class which has the complete information. Compilers also used to not tell us about properties, though this has been fixed in recent clang builds. So when ever we see an objective C class, now the debugger has to go through ALL modules to try and find the one complete definition for a given type and ignore the type that it has been given in the debug info. 

I agree it is nice to hide this stuff, but it really makes it a pain for the debuggers to deal with. Rest assured we are currently working on this.
