React-Native AsyncStorage.clear() is failing on IOS

Question

I'm using AsyncStorage.clear() which is working just fine on Android but when run using iOS platform (real device) I'm getting this error and can't find anything online about it.

Error: Failed to delete storage directory.Error Domain=NSCocoaErrorDomain Code=4 "“RCTAsyncLocalStorage_V1” couldn’t be removed." UserInfo={NSFilePath=/var/mobile/Containers/Data/Application/281A6456-6CB2-47D4-AD04-3EB26A1B9506/Documents/RCTAsyncLocalStorage_V1, NSUserStringVariant=(
    Remove
), NSUnderlyingError=0x174049480 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}

Answer 1

I think it's crappy that clear throws an exception when the storage has never been used; at least that is what I'm thinking is the case?

So to move on I modified code removing the use of .clear() and replacing it with AsyncStorage.getAllKeys().then(AsyncStorage.multiRemove)

I'd still like an reason if anyone knows what is going on.
