I use this code for go to new story board and pass variable X to a viewController in new storyboard

```
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let homeViewController: UIViewController = mainStoryboard.instantiateViewController(withIdentifier: "ViewControllerCall")
homeViewController.myVar = "x"
self.present(homeViewController, animated: true, completion: nil)

```

But I get this error: 

> 
> Value of type 'UIViewController' has no member 'myVar'
