get label value on uiswitch value change inside table view cell swift

i have a UITableviewcell with a label and switch.

enter image description here

cell label have dynamic values according to situation.

when i on/off switch. it just shows tag that which row switch state is changed. but i want to get exactly what is on label where switch is on/off.

 switchView.tag = indexPath.row // for detect which row switch Changed
 switchView.addTarget(self, action: #selector(self.switchChanged(_:)), for: .valueChanged)

//switch value change function
@objc func switchChanged(_ sender : UISwitch!){

        print("table row switch Changed \(sender.tag)")
       //looking for label text on this tag 
    }

is there any way to get cell label value when switch state changed inside tableview cell.

declare following closure variable in UItableViewCell

var returnBlock: ((String?)-> Void)?

and in switch method just call it with labelObj.text 

    @objc func switchChanged(_ sender : UISwitch!){
             returnBlock?(labelObject.text)
        }

In TableViewController - CellForRowAtIndexPath method where you return cell before that write following code. 

    cell.returnBlock = { labelText in 
               if let value = labelText {
                print(value)
               }
     }

There is many ways to do, but i think this is proper way.

For default UITableViewCell 

  @objc func switchChanged(_ sender : UISwitch!){
        if let cellObj =  tableView.cellForRow(at: IndexPath(row: sender.tag, section: 0)) as? UITableViewCell {
     print(\(cellObj.labelObj.text ?? ""))
    }
   }
