cell AtIndexPath method


As we want to display only the names of the customers in the table view, in the cell AtIndexPath method, we retrieve the managed object from the fetchedResultsController instance. The NSFetchedResultsController stores the set of entities from an NSManagedObjectContext (retrieved on the basis of FetchRequest). Then the value stored in the name attribute of the managed object is assigned to the table cell for display.
