First you need to add this function

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true 
}

then your function is ok but no need of tableview reload data just call tableview.beingUpdates and tableview.endUpdates

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
       print("Deleted")
       self.catNames.remove(at: indexPath.row)
       self.tableView.beginUpdates()
       self.tableView.deleteRows(at: [indexPath], with: .automatic)
       self.tableView.endUpdates() 
    }
}
