How to get row order info in multivalued section?

Question

I am using MultivaluedSection with an option .Reorder to reorder my cells, for which I need to know the exact order.

I tried with section.allRows, form.allRows, form.values() but seems like they all do not keep the information about order, even though they return an Array.

Note: I was trying to catch this data in overridden:

func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath)

Answer 1

Actually I realized that after overriding that method I was "killing" that update, of course.

Still, I don't know how to "catch" when a change happens.
