Opening a View Controller that is connected to a navigation Controller programatically

Question

I am using AKSwiftSlideMenu as basis for an app.

I have a view controller (HomeVC) that is connected to a navigation controller.

If the storyboard entry point is pointing to HomeVC then I get the menu of course, but my app needs to start without the menu and only after certain screens and tasks that are done i want to navigate to HomeVC and allow user access to the menu.

I noticed that if a i place a button on a starting view controller that does not have a connection to the navigation controller, and connect that button directly to the Navigation controller by drag+cntrl then pressing the button will get me from a view controller without a menu to HomeVC and show the menu.

How do i do that programmatically

Thanks in advance for any help

edit: I have tried the following code

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

which did not work resulting with the following err

Could not cast value of type 'myApp.HomeVC' (0x10a159280) to 'UINavigationController' (0x10cc2d3c8).

Please give more information on what do you want. If possible share some screens or a flow diagram. Thanks — Shubham Aggarwal, May 14 '17 at 11:07
hi, added flow diagram. What i want is from start point view controller to get to the view controller where menu is shown, but programatically and not via a button and segue. — Johny D Good, May 14 '17 at 11:33

let newViewController = storyBoard.instantiateViewController(withIdentifier: "Home") as! UINavigationController

"Home" is not a UINavigationController. Remove as! UINavigationController from this line and the error will go away.

Hi Daniel, true that removing as! UINavigationController opens HomeVC view controller but without the menu of the navigation controller thus the menu is not seen in view. The same would happen if i had attached start button directly to homeVC and not to the navigation controller. – Johny D Good May 14 '17 at 13:44
Then instantiate the navigation controller and present it instead of instantiating the home view controller. – Daniel T. May 14 '17 at 13:46

thank you Daniel for telling me to instantiate navigation controller. Ended up giving navigation controller a storyboard id named ccontroller and the following code does what I needed

    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: "ccontroller") as! UINavigationController
    self.present(vc, animated: true, completion: nil)
