问题
I installed Xcode 12 on my Mac, tried building my react native app that runs perfectly on android, and get 'atomic_notify_one<unsigned long>' is unavailable. This is the most information I get from the error.

This error was an error from flipper. Flipper threw several more less descriptive errors that I had to comment it on my podfile. After commenting, this error stopped.
