Updating Label in Cell - ios

Question

I have a TableView which rows contain label and two buttons. What I wanna do is that when a user clicks the first button "Set Name", a pop up view comes up in which he can input text from keyboard. After hitting "Set", pop up view is dismissed and label inside a row containing the clicked button changes to the input text. I set the delegates but I cannot make label to change.
TableView:
import UIKit
class SetGame: UIViewController, UITableViewDelegate, UITableViewDataSource
{
var numOfPlayers = Int()
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return numOfPlayers
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
cell.Name.text = "Player \(indexPath.row + 1)"
cell.btn1.tag = indexPath.row
cell.btn2.tag = indexPath.row
return cell
}
override func viewDidLoad()
{
super.viewDidLoad()
self.tableView.separatorStyle = UITableViewCellSeparatorStyle.none
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
}
#IBAction func setName(sender: UIButton)
{
let thisVC = storyboard?.instantiateViewController(withIdentifier: "SetName") as! SetName
thisVC.delegate = self
present(thisVC, animated: true, completion: nil)
}
#IBAction func setFingerprint(_ sender: UIButton)
{
}
#IBAction func unwindToSetGame(_ segue: UIStoryboardSegue)
{
print("unwinded to SetGame")
}
#IBOutlet weak var tableView: UITableView!
}
extension SetGame: nameDelegate
{
func named(name: String)
{
let indexP = IndexPath(row: 0, section: 0)
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexP) as! TableViewCell
cell.Name.text = "bkjhvghcjhkv"
//wanted to see if it changes first cell. But doesn't work
}
}
TableViewCell Class:
import UIKit
class TableViewCell: UITableViewCell
{
override func awakeFromNib()
{
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool)
{
super.setSelected(selected, animated: animated)
}
#IBOutlet weak var Name: UILabel!
#IBOutlet weak var btn1: UIButton!
#IBOutlet weak var btn2: UIButton!
}
Pop up View:
import UIKit
protocol nameDelegate
{
func named(name: String)
}
class SetName: UIViewController
{
var delegate: nameDelegate!
override func viewDidLoad()
{
super.viewDidLoad()
window.layer.borderWidth = 1
window.layer.borderColor = UIColor.white.cgColor
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
}
#IBAction func closePopUp(_ sender: Any)
{
if input.text != ""
{
delegate.named(name: input.text!)
}
dismiss(animated: true, completion: nil)
}
#IBOutlet weak var input: UITextField!
#IBOutlet weak var window: UIView!
}

Replace this
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexP) as! TableViewCell
with
let cell = tableView.cellForRow(at:indexP) as! TableViewCell
