In addition to what @Levi suggested, you should not access the instance variable fetchedResultsController directly in numberOfRowsInSection (or in other table view data source methods). Always use the property accessor self. FetchedResultsController .
Before the return _fetchedResultsController; line in your method, tell the NSFerchedResultsController to execute the request.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
