I have an issue with recursive git submodules in my Xcode workspace. I think that llvm is picking up the wrong .m file.
I'd like to confirm this by showing the methods available in the object binary.
I know that I can use ar -t myarchive.a to show the .o files in a static library. Is there any way to drill down deeper and show the method symbols available on a specific .o?
Use can use the nm command to show the symbols within .o or .a file. See the nm manpage for details.
$ nm build/IoEvent.o

If you're using C++ (I know you're not) then you can use c++filt to demangle those symbol names:
$ c++filt __ZN9ChessCore7IoEvent5resetEv
ChessCore::IoEvent::reset()
