Answer 1

Swift 5

class MyNavigationController: UINavigationController {
    
    var myData: String!
    
    override func viewDidLoad() {
        if let vc = self.topViewController as? MyViewcontoller{
            vc.data = self.myData
        }
    }
    
}

   let navigation = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "MyNavigationController") as! MyNavigationController
   navigation.myData = "Data that you want to pass"
   present(navigation, animated: true, completion: nil)
