I had this exact same problem. I had accidentally deleted by Info.plist file in my ios directory. Restoring it, fixed my issue.
I had same issue not quite long, running react-native links will give you error.
If you are using yarn simply run:
yarn remove react-nativeyarn add react-nativereact-native linkThis fixed it for me.
I had this problem and in my case it was because I had renamed the project but forgotten to update newname in a few folders and files.
