Value of type 'UICollectionView' has no member 'beginUpdates' - Swift 3 issue

Question

I was using NSFetchedResultsController for core data .

And on implementing controllerWillChangeContent() method.

        self.collectionView.beginUpdates()

shows error from Xcode 8 , swift 3 .

Any suggestion.

Answer 1

beginUpdates is from UITableView. UICollectionView has the performBatchUpdates(_:completion:) method.

I suggest reviewing this answer for information on using NSFetchedResultsController and UICollectionView.
