How to add a default ViewController along with the navigation drawer ViewController - ios

Question

I have implemented a menuViewVontroller for navigation drawer that works fine. I am able to render the view controllers on their respective menu buttons. I have one ViewController that loads up first and then I display other view controllers from the navigation menu i.e. Home menu displays the homeViewVontroller etc. as you can see in the screen shots.
But I also want my app to show the homeControllerView when the viewController loads. It is currently rendering an empty screen as the view controller is empty. When I write the below code in viewDidLoad() method, I am not getting the navigation drawer, just the homeViewController gets displayed (as shown in the picture below).
let view = UIView()
let controller = storyboard!.instantiateViewController(withIdentifier: "SliderController")
addChild(controller)
view.frame = self.view.bounds
self.view.addSubview(controller.view)
self.topView = view
What can I do to render both the homeViewController and the menuViewController in the same screen.
EDIT: My code when the user presses the menu item
#IBAction func didTapMenuButton(_ sender: UIBarButtonItem) {
guard let menuViewController = storyboard?.instantiateViewController(withIdentifier: "MenuViewController") as? MenuViewController else { return }
menuViewController.didTapMenuType = {
menuType in
self.transitionToNew(menuType)
}
menuViewController.modalPresentationStyle = .overCurrentContext
menuViewController.transitioningDelegate = self
present(menuViewController, animated: true)
}
func transitionToNew(_ menuType: MenuType) {
let title = String(describing: menuType).capitalized
self.title = title
topView?.removeFromSuperview()
switch menuType {
case .promotion:
let view = UIView()
view.backgroundColor = .yellow
view.frame = self.view.bounds
self.view.addSubview(view)
self.topView = view
case .billPayment:
let view = UIView()
view.backgroundColor = .blue
view.frame = self.view.bounds
self.view.addSubview(view)
self.topView = view
default:
break
}
}
