SFSafariViewController: Hide navigation bar

Question

I was able to get my app to automatically load a url via the SFSafariViewController per this post, and it works great, the only drawback is the navbar.

The SFSafariViewController navbar is kind of useless when being used this way, as the url is read-only, and the 'done' link doesn't do anything but reload the page. As such, I would like to hide the navbar altogether.

Per the comments attached to accepted answer, it was suggested to set my root view controller to SFSafariViewController which I can't get working. The setup is simple as there is a single view controller with the code included in the aforementioned post.

How can I hide the navbar but still maintain the benefits of the SFSafariViewController? Or if I can't hide the navbar, at least hide the 'done' link?

Code snippet:

import UIKit
import SafariServices

class ViewController: UIViewController
{
    private var urlString:String = "https://example.com"

    override func viewDidLoad()
    {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func viewDidAppear(animated: Bool)
    {

        super.viewDidAppear(animated)

        let svc = SFSafariViewController(URL: NSURL(string: self.urlString)!)

        self.presentViewController(svc, animated: true, completion: nil)

        self.navigationItem.rightBarButtonItem = nil
    }

    override func didReceiveMemoryWarning()
    {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

----- Works. Navbar is "hidden" -----

import UIKit
import SafariServices

class ViewController: UIViewController
{
    private var urlString:String = "https://example.com"

    override func viewDidLoad()
    {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        // This will remove the status (battery, time, etc) bar
        UIApplication.sharedApplication().statusBarHidden = true
    }

    override func viewDidAppear(animated: Bool) {

        super.viewDidAppear(animated)

        let svc = SFSafariViewController(URL: NSURL(string: self.urlString)!)

        // Kind of a hack, in that we really aren't removing the navbar
        //  Rather we are adjusting the starting point of the vpc object so it appears as the navbar is hidden
        self.presentViewController(svc, animated: true) {

            var frame = svc.view.frame
            let OffsetY: CGFloat = 42

            frame.origin = CGPoint(x: frame.origin.x, y: frame.origin.y - OffsetY)
            frame.size = CGSize(width: frame.size.width, height: frame.size.height + OffsetY)
            svc.view.frame = frame
        }
    }

    override func didReceiveMemoryWarning()
    {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    // For this to work be sure to set the following setting to OFF, in info.plist
    //  'View controller-based status bar appearance'
    override func prefersStatusBarHidden() -> Bool {
        return true
    }
}

import Foundation
import UIKit
import SafariServices

class MySafariFullScreenViewController: UIViewController  {

    override func viewDidLoad() {
        super.viewDidLoad()
        //WONT WORK read only you need to override it in this VC or in SFSafVC using extension - see bottom of this code
        //self.prefersStatusBarHidden = true

    }

    override func viewDidAppear(_ animated: Bool){
        let urlString = "https://......"
        //if a log screen - i think SFSafariViewController can handle this
        //let urlString = "https://<domain>login?redirect=https:<homescreen>"


        if let url: URL = URL(string: urlString) {
            let safariViewController = SFSafariViewController(url: url)
            present(safariViewController, animated: true) {

                var frame = safariViewController.view.frame
                //if status bar not hidden
                l//et OffsetY: CGFloat  = 64
                //if status bar hidden
                let OffsetY: CGFloat  = 44

                frame.origin = CGPoint(x: frame.origin.x, y: frame.origin.y - OffsetY)
                frame.size = CGSize(width: frame.width, height: frame.height + OffsetY)
                safariViewController.view.frame = frame


            }
        }else{
            //url error
        }



    }
    //this is for this vc - but for SFSafariVC you need override using extension
    override var prefersStatusBarHidden: Bool{
        get{
            return true
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

extension SFSafariViewController{
     override open var prefersStatusBarHidden: Bool{
        get{
            return true
        }
    }
}
