    Same thing here! after almost having a game ready for submission to the App Store, I decided to upgrade to Sierra. Been hell the last couple days, I'm downloading El Capitan to see if I can finally finish this project with no more bumps. :P

    Same thing happening EVERY single time I'm building & run.

    Fix it please. It's annoying.
