Show navigation to Controller programatically

Question

I am changing a menu VC over from StoryBoard to programatic operation.

When I want to load another VC I was using the Action Segue "Show".

The temporary code I am using works but pops the VC over the top. Can you action the "Show" equivalent programatically, and if so how?

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "SunriseSunsetResultsViewController")
self.present(newViewController, animated: true, completion: nil)

Answer 1

To do what a Show segue used to do, replace present with show:

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "SunriseSunsetResultsViewController")
self.show(newViewController, sender: self)

Note, however, that this will do the same thing as present unless self.navigationController is not nil. In other words, you cannot do the sideways navigation you were doing before unless a navigation controller is in charge of the interface.

Instead of show you could say pushViewController etc., but the same caveat applies. Only a navigation controller can do what you were doing previously.
