Passing Data between view Controllers Using a segue from a view embedded in a navigation controller to a tabbarcontroller

Question

I have two views that I would like to pass data from one view to the next. The first view is where I have the data that I would like to pass to the next view lets call it SourceViewController. However SourceViewController is embedded in a NavigationViewController and the secondViewController lets call it DestinationViewController is the firstView in a TabViewController.

I have tried to use the answer from this question and it fails to go past navigation view it just skips the whole logic.

This is my code :

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if (segue.identifier == "loginSuccessSugue") {

        if let tab = self.presentingViewController as? UITabBarController,
            let nav = tab.viewControllers?[0] as? UINavigationController,
            let destinationVC = nav.viewControllers.first as? HomeViewController {


             destinationVC.currentBalance = serviceBalance
        }

    }
}

This is the HomeViewController:

class HomeViewController: UIViewController , UITableViewDelegate,UITableViewDataSource, UICircularProgressRingDelegate{

var currentBalance = 0.0

 override func viewDidLoad() {
    super.viewDidLoad()

    circularBalance.maxValue = CGFloat(currentBalance)
     print(currentBalance)

   }

  override func viewDidAppear(_ animated: Bool) {
    print(currentBalance)
    circularBalance.setProgress(value: CGFloat(currentBalance), animationDuration: 3)

     }
}

This is how the storyboard looks like:

Answer 1

This is my view controller where you can check that I am sending 5 to tabbar first viewcontroller:

   class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        self.performSegue(withIdentifier: "segueIdentifier", sender: self)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        let barViewControllers = segue.destination as! UITabBarController
        let destinationNv = barViewControllers.viewControllers?[0] as! UINavigationController
        let destinationViewController = destinationNv.viewControllers[0] as! FirstViewController
        destinationViewController.currentBalance = 5
    }
}

Now You can check my firstview controller where you can check that what value we are getting.

class FirstViewController: UIViewController {

    var currentBalance = 0
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        print(currentBalance)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

Now, You can check my console and storyboard:
