Deletes are processed before inserts in batch operations. This means
the indexes for the deletions are processed relative to the indexes of
the collection view’s state before the batch operation, and the
indexes for the insertions are processed relative to the indexes of
the state after all the deletions in the batch operation.
Fatal Exception: NSInternalInconsistencyException attempt to delete
and reload the same index path
For the move operations, the from indexPath is pre-delete indices, and the to indexPath is post-delete indices. Reloads should only be specified for indexPaths that have not been inserted, deleted, or moved. This is probably why you're seeing the
A handy way to verify the operations are set up correctly: the set of reload, insert and move-to indexPaths should not have any duplicates, and the set of reload, delete, and move-from indexPaths should not have any duplicates.
It appears that items that you move are not also updated, but only moved. So, if you need to update and move an item, you can perform the reload before or after the batch update (depending on the state of your data source).
