First I thought I’ve grocked that thing: It’s the data source for a UITableView. But then: It does not conform to that data source protocol. Strange! Why? How can it not?

NSFetchedResultsControlleris not a data source. It’s the intermediary between the data source and theUITableView. For example, it can notify theUITableViewwhen its data source changes. This prevents coupling between the data source theUITableView, which would violate the MVC pattern.
