As I mentioned before, I accidently upgraded xcode, and obviously the upgrade (or something else caused by upgrade) broke my previous AWS app – at the beginning it does not build, and after tweak the project file, it refused to run. Instead of doing further more troubleshooting job, I just uninstall and reinstall the whole xcode tool chain, and obviously this is the simple and quick solution (other than Giga data of download).
