For this i'm using the default UITableViewDelegates (numberOfRowsInSection, numberOfSections etc) - If they are relevant i'll post them in an edit. When the tableview loads and i have set the fetchController and have performed a fetch i pretty-print its objects to test what it holds and if the sort-descriptors have done their job.
