Hello u can take cheboxbutton action method inside view controller with addtarget method and assign tag indexpath.row so u can easily get the indexpath. from below code u can get the idea.

class ViewController:UIViewController,UITableViewDelegate,UITableViewDataSource {

@IBOutlet weak var ObjTableview: UITableView!
var arrStudent = ["1","2","3","4","5"]
var arrSelectedStudent :[Int] = []
var selectAll:Bool = false

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


//MARK: UITableViewDataSource
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return arrStudent.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    // create a new cell if needed or reuse an old one
    let cell = ObjTableview.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! SelectUserCell
    // set the text from the data model
    cell.selectionStyle = UITableViewCellSelectionStyle.none
   // cell.lblStudentName.text = getStudentName[indexPath.row]
    cell.lblStudentName.text = arrStudent[indexPath.row]
    cell.btnCheckbox.tag = indexPath.row
   cell.btnCheckbox.addTarget(self, action:#selector(btnCheckBoxClick(sender:)), for: .touchUpInside)


    if selectAll {
        cell.btnCheckbox.setImage(UIImage(named: "selectedItem"), for: .normal)
    }else{
    if arrSelectedStudent.contains(indexPath.row){
        cell.btnCheckbox.setImage(UIImage(named: "selectedItem"), for: .normal)
    }else{
        cell.btnCheckbox.setImage(UIImage(named: "unSelectedItem"), for: .normal)
    }
    }

         return cell
}


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

func btnCheckBoxClick(sender: UIButton) {
    if sender.tag == 0{
        selectAll = true
    }else
    {
        selectAll = false
    if let index = arrSelectedStudent.index(of: sender.tag) {
        arrSelectedStudent.remove(at: index)
    }else{
        arrSelectedStudent.append(sender.tag)
    }
    }

    ObjTableview.reloadData()
}}
