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

Answer 1

When AsyncStorage is empty...

AsyncStorage.clear()
errors on iOS but not Android.

AsyncStorage.getAllKeys().then(AsyncStorage.multiRemove)
errors on Android but not iOS.

Our solution...

import {  Platform } from 'react-native';
import AsyncStorage from '@react-native-community/async-storage';

const asyncStorageKeys = await AsyncStorage.getAllKeys();
if (asyncStorageKeys.length > 0) {
  if (Platform.OS === 'android') {
    await AsyncStorage.clear();
  }
  if (Platform.OS === 'ios') {
    await AsyncStorage.multiRemove(asyncStorageKeys);
  }
}

Answer 2

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.
