Description
This fixes AsyncStorage data loss on iOS.
We had modules importing
AsyncStoragefrom React Native Core and some others from React Native Community. The 2 implementations were essentially competing and causing the problem.Since both implementations currently write to the same file on disk, the last one to write wins and erases the existing data written by the other.
See react-native-async-storage/async-storage#118 (comment)
Though I updated the offending import in Apollo, the fix here also makes sure this problem won't sneak back in if we add a dependency which still imports
AsyncStoragefrom React Native Core. This is done by monkey patching React Native so it also returns the community implementation of AsyncStorage.Pretty scary bug, I'm glad we didn't ship that 😅
Tested
Followed the steps to reproduced the issue as described in #2248, and observed the problem doesn't happen anymore.
