I also had the same problem mentioned above. Selecting libc++ gave me the ext/atomicity.h exception. Selecting libstdc++ gave me the list of Undefined symbols. I tried recompiling OpenCV with the GCC options in the Toolchain files but that didn't help (so I reverted back to the standard state).

After checking all of the Build Settings attributes, I noticed that the Framework Search Path had several entries for other versions of OpenCV that I've upgraded from in the past. After removing all of the outdated ones, I was able to get my project to compile without the ext/atomicity.h exception.
