Failing to pass data between VC

I have two VC's and I'm trying to pass data from the first VC to the second using a segue. The first VC has a tableview each cell contains a title and a description labels that are stored using core data. I want to have a detail view of each cell in the second VC. I have initialized two strings to store the values from the first VC and assigned them to strings in the second VC.

Please take a look at the code below:

var SelectedTitle = String()
var SelectedDisc = String()

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    SelectedTitle = self.listAthkar[indexPath.row].title!
    print(SelectedTitle)
    SelectedDisc = self.listAthkar[indexPath.row].details!
    print(SelectedDisc)
    performSegue(withIdentifier: "showCell", sender: self)
}


override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if (segue.identifier == "showCell") {
        var destinationVC = segue.destination as! showCellVC
        destinationVC.passedTittle = SelectedTitle
        destinationVC.passedDisc = SelectedDisc
    }
}


class showCellVC: UIViewController {

var passedTittle = String()
var passedDisc = String()
@IBOutlet weak var cellTitle: UILabel!
@IBOutlet weak var cellDisc: UITextView!

override func viewDidLoad() {
    super.viewDidLoad()
    cellTitle.text = passedTittle
    cellDisc.text = passedDisc
    print("Title Passed is \(passedTittle)")
    print("Discription Passed is \(passedDisc)")
}

When I test the app the console prints: 

Title Passed is 
Discription Passed is 
title
Description

Here is a picture of the actual cell

Cell picture Any idea why it's failing to pass the data to the second VC?

It looks like you have put an action segue on your tableview cell in your storyboard. Since you are using a programmatic segue you don't want this. The action segue is firing before your didSelect method, so the segue is occurring before the variables are set.

Try like this! Make separate Array for "Title" and "Description"

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

    self.performSegue(withIdentifier: "showCell", sender: indexPath)
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

   if (segue.identifier == "showCell") {
    var destinationVC = segue.destination as! showCellVC
    destinationVC.passedTittle = self.listAthkar[(sender as! IndexPath).row]
    destinationVC.passedDisc = self.listAthkar[(sender as! IndexPath).row]
   }
}
