Having implemented so many different features with Core Data such as creating, updating, and deleting objects in our app, you should be familiar with how difficult it can be in term so updating our UI to reflect these changes. Today we look at a very easy to use component called NSFetchedResultsController that helps us monitor for changes. In addition to monitoring, it will also give us the correct IndexPath objects for which these changes are occurring inside a UITableView and UICollectionView. Please look at the link in the resources for more information on how this awesome component works.
