Answer 1

Check your .babelrc file. Is it including the babel transform-async-to-generator plugin? If so, remove it. The babel helpers that React Native includes do not include the helper for that transform. I'm not sure how to add it without generating a new set of helpers and including them in your build. If that plugin is not in your babel config, maybe one of the library dependencies you are using has it.
