Assertion Failure in UICollectionViewData indexPathForItemAtGlobalIndex

Question

I am using performBatchUpdates() to update my collection view, where I am doing a complete refresh, i.e. delete whatever was in it and re-insert everything.

Answer 1

If you remove the last cell from a section containing header/footer the bug appears.

I tried to return nil for header/footer size/element at that time and this sometimes fixes the issue.

Options:

1. Reload the whole table view instead of animating the removal of the last item.
2. Add an additional invisible, basic cell with a size less than 1.
