How to make image view fill out all the screen in Swift in second storyboard

Question

I am trying to create a second Storyboard. I want it to be similar to the first Storyboard background. I insert UIImageView and fit it all the page, however, why it is not fitting the entire page as shown in the image below:

Answer 1

let vc = UIViewController()
vc.modalPresentationStyle = .fullScreen //or .overFullScreen for transparency
self.present(vc, animated: true, completion: nil)

Answer 2

Set the presentation of ViewController in storyBoard.
