      if editingStyle == .delete {
        print("Deleted")

        self.catNames.remove(at: indexPath.row)
        self.tableView.deleteRows(at: [indexPath], with: .automatic)
      }

Answer 2

You don't have to reload the tableView.

Before you use tableView.deleteRows(at: [IndexPath], with: UITableView.RowAnimation) you must substrate the number of rows you want delete in numberOfRowsInSection

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

return //Your current number of rows - The number of rows to delete

    }

Normally the number of rows is the number of Items from an array (yourArray.count), that means you can delete the items from this array before you delete the cells and you get the same result.
