Jayprakash, You are almost there. You need to modify some lines -

Here is your modified code snippet

var unchecked:Bool = true

@IBAction func btnCheckBoxClick(_ sender: Any) {

    if(unchecked){

        unchecked = false
    }
    else{

        unchecked = true
    }


    ObjTableview.reloadData()


}



func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    if(indexPath.row == 0){

            btnCheckBoxClick(sender: UIButton())

      }

 }


func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{

        let cell : SelectUserCell!
        cell = tableView .dequeueReusableCell(withIdentifier: "SelectUserCell", for: indexPath) as! SelectUserCell
        cell.selectionStyle = UITableViewCellSelectionStyle.none


       if(unchecked){

              cell.btnCheckbox.setImage(UIImage(named: "unSelectedItem"), for: .normal)

         }
       else{

              cell.btnCheckbox.setImage(UIImage(named: "selectedItem"), for: .normal)
         }


   // Do your stuff here

   return cell
}

Hop it will simplify your code structure.
