How to create Segue which make view controller fullscreen in Xcode 11.1

Question

When I try to create segue via storyboard it's only does open new view controller as pop out instead of fullscreen. I tried changing kind of segue from,,Show (eg Push)" to others but then I get "Thread 1: signal SIGABRT"

Answer 1

You need to select present modally for the segue type and then right below select the presentation style full screen :

Answer 2

What you need to do is set the destination view controller's modalPresentationStyle to fullscreen by way of prepareForSegue:sender: :

class FirstViewController: UIViewController {

    ...

    @IBAction func segueButtonPressed(_ sender: Any) {
    }

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        super.prepare(for: segue, sender: sender)

        if let secondViewController = segue.destination as? SecondViewController {
            secondViewController.modalPresentationStyle = .fullScreen
        }
    }
}

prepareForSegue:sender: is called before a segue is performed from a UIViewController . The default modalPresentationStyle in iOS 13+ is .pageSheet , which is the presentation that doesn't cover the whole screen (though it allows for more natural navigation/dismissal via swiping the view controller down and off the screen). We need to change this modalPresentationStyle to .fullScreen before performing the segue.
