Instantiate view controller created in storyboard from a storyboard less view controller

Question

I have two View Controllers:

1. MainController.swift - Soryboard less view controller
2. SecondController.swift - Storyboard view controller

How can I instantiate SecondController in MainController ?

storyboard?.instantiateViewController(withIdentifier: _) does not work because MainController has no storyboard.

Answer 1

How can I open SecondController in MainController?

It depends what “open” means. You can, for example, say

present(SecondController(), animated:true)

Or you might push it onto a navigation controller if there is one in the interface. That sort of thing, and similar, are quite standard. Storyboards are a relatively recent innovation; when I started programming iOS everything was done without them.

Answer 2

Use init(name:bundle:) :

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let secondVC = storyboard.instantiateViewController(withIdentifier: "SecondController") as! SecondController
