Tableviewcell data won't translate to another view controller - json

Question

I did a parse json in my listingshopvc and it shows.Now I want to select a row and it pops up another view controller but there's error just a blank page with no error. I just want to press a row and convert it to show up on another view controller.
I have listing in the following view controller: ListingShopVc,ProductDetail,TableCellData
ListingShopVC
import UIKit
import CoreData
class ListingShopVC: UIViewController, UITableViewDelegate, UITableViewDataSource{
#IBOutlet weak var tableView: UITableView!
#IBOutlet weak var creditsdisplay: UILabel!
var context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
var myUser:[User] = []
var mySecond:[Product] = []
var id:String = ""
var name:String = ""
var price:Double = 0.0
var image:String = ""
var details:String = ""
override func viewDidLoad() {
super.viewDidLoad()
fetch()
tableView.delegate = self
tableView.dataSource = self
extracted()
creditsdisplay.text = "You have 200 credits"
}
// MARK: - Table view data source
func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return mySecond.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "hello", for: indexPath) as! TableCellData
// Configure the cell...
cell.shopTitle.text = mySecond[indexPath.row].name
cell.shopPrice.text = "$" + String(mySecond[indexPath.row].price) + "0"
cell.shopDesc.text = mySecond[indexPath.row].description

-> You just need to call a delegate method of table view didSelectRowAt
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let tag = projectEquipmentList?[indexPath.row].tag // Object data to take in next VC
let QR = R.storyboard.main.qrScannerVC()! // View Controller
QR.manageVC(projectEquipmentTag: tag!) // setter method of View controller to set data
navigationController?.pushViewController(QR, animated: true) // push to next view controller
}
