targetIndexPathForMoveFromRowAt is not getting called

[testproject1234]

func tableView(_ tableView: UITableView, targetIndexPathForMoveFromRowAt sourceIndexPath: IndexPath, toProposedIndexPath proposedDestinationIndexPath: IndexPath) -> IndexPath {
    if sourceIndexPath != proposedDestinationIndexPath {
        return sourceIndexPath
    }
    return proposedDestinationIndexPath
}

I want to avoid reorder the section of rows to new section. But this delegate is not getting called
