    var items = [item]()
    var price : String = ""

    @IBOutlet weak var paymentdetails: UILabel!


    @IBOutlet weak var cardnametextfield: UITextField!


    @IBOutlet weak var validthrutextfield: UITextField!


    @IBOutlet weak var cardnumbertextfield: UITextField!

    @IBOutlet weak var cvcnumbertextfield: UITextField!

    @IBOutlet weak var labelprice: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()
    labelprice.text = price


        // Do any additional setup after loading the view.
    }


    @IBAction func paybutton(_ sender: Any) {

        if cardnametextfield.text == "" {
            alertMessage(titleInput: "Error, Payment Unsuccessful!", messageInput: "Please Fill all the fields")
        } else if validthrutextfield.text == "" {
            alertMessage(titleInput: "Error, Payment Unsuccessful!", messageInput: "Please Fill all the fields")
        } else if cardnumbertextfield.text == "" {
            alertMessage(titleInput: "Error, Payment Unsuccessful!", messageInput: "Please Fill all the fields")
        } else if cardnumbertextfield.text == "" {
        alertMessage(titleInput: "Error, Payment Unsuccessful!", messageInput: "Please Fill all the fields")
        } else {
            alertMessage(titleInput: "Success!", messageInput: "Payment Successful!")

            self.transitionToHomePage()
        }
    }

    func alertMessage(titleInput: String, messageInput: String){
        let alert = UIAlertController(title: titleInput, message: messageInput, preferredStyle: UIAlertController.Style.alert)
        let paybutton = UIAlertAction(title: "OK", style: UIAlertAction.Style.default, handler: nil)

        alert.addAction(paybutton)
        self.present(alert, animated: true, completion: nil)
    }

    func transitionToHomePage(){
         let TabHomeViewController = storyboard?.instantiateViewController(identifier: Constrants.Storyboard.TabHomeViewController) as? UITabBarController

        view.window?.rootViewController = TabHomeViewController
        view.window?.makeKeyAndVisible()
    }

}

First you should make a struct

struct Item {
  let title,price,imageName:String
}

instead of the 3 arrays make 1

var arr = [Item]()

and fill it

Second

override func prepare(for segue: UIStoryboardSegue, sender: (Any)?){
    var des = segue.destination as! PaymentViewController 
    if let row = tableView.indexPathForSelectedRow?.row {
        des.price = arr[row].price
    } 
}

Finally connect the segue from the tableView not from the cell and dragged it to the destination vc , then inside didSelectRowAt delegate method of table dp

self.performSegue(withIdentifier:"SegueNameHere",sender:nil)
