Adding new Viewcontroller's view as subview

Question

I am trying with the following and failed to add new viewcontrollers view. Is it only way to present view controller ? Cant we add view from other storyboard viewcontrollers view?

  //Working
    let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "customView") as! CustomViewController

    self.present( viewcontroller , animated: true, completion: nil)

    //Not working
    let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "customView") as! CustomViewController
    vc.view.frame = self.view.frame
    self.view.addSubview(vc.view)

You need to also add CustomViewController as ChildViewController in your current Controller.

let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "customView") as! CustomViewController
vc.view.frame = self.view.bounds
self.addChildViewController(vc)
self.view.addSubview(vc.view)
vc.didMove(toParentViewController: self) //OR  vc.willMove(toParentViewController: self)

thank you! I have tried for adding some other views vc.customView to self.view but failed. Is this possible to add part of vc with defined frame into self.view like self.view.addsubview(vc.customview) : vc from storyboard

@GobiM I haven't try something like that, have you try by adding it, vc.customview is not load yet so may be it will give you nil, You can check it by simply trying once.
