func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
            let action =  UIContextualAction(style: .normal, title: "", handler: { (action,view,completionHandler ) in
                //do stuff
                completionHandler(true)
                let data:NSDictionary = self.conversations[indexPath.row] as! NSDictionary
                print(data)
                let alert:UIAlertController = UIAlertController(title: "", message: "are you sure want to delete ?", preferredStyle: .alert)

                alert.addAction(UIAlertAction(title: "CANCEL", style: UIAlertActionStyle.cancel, handler: { (action) in
                }))
                self.present(alert, animated: true, completion: nil)
            })
            action.image = UIImage(named: "")
            action.backgroundColor = UIColor(red: 0/255, green: 148/255, blue: 204/255, alpha: 1.0)
            let confrigation = UISwipeActionsConfiguration(actions: [action])

            return confrigation
        }
