How to implement the multiple selection in uitable in swift3?

Question

currently, i have added a long press gesture to my table view. It is working fine. Now the thing i want is that if i long press any UITableview cell that cell should get selected and after this if i tap on next cells that too should get selected too. Below is the code:

 func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 10
    }

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

        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        let row = indexPath.row
        cell.textLabel?.text = "Label"

        return cell
}


    @IBAction func longPress(_ guesture: UILongPressGestureRecognizer) {

        if guesture.state == UIGestureRecognizerState.began {
            print("Long Press")
        }
    }

You can set the tableView's allowsMultipleSelection property in your longPress method. Since the longPress won't trigger the cell's selection you can you can use the gesture's location in the tableView to get the initial cell that corresponds to the longPress action.

func longPress(sender:UILongPressGestureRecognizer)  {
    switch sender.state {
    case .began:
        tableView.allowsMultipleSelection = true
        let point = sender.location(in: tableView)
        selectCellFromPoint(point: point)
    default:break
    }
}

func selectCellFromPoint(point:CGPoint) {
    if let indexPath = tableView.indexPathForRow(at: point) {
        tableView.selectRow(at: indexPath, animated: true, scrollPosition: .none)
    }
}
