Let's say I have 5 objects from api.
I store them using realm.add(item, update: true) which will create or update 5 objects.
Next time, one item is removed from server side.
So when I call api afterward, total number of realms objects should be 4. Not 5.
Using realm.add(item, update: true) will not remove the un-included items from api. It stores only add or update.
What's the best way to handle that?
