ios – ModalPresentationStyle fullscreen of UINavigationController does not work

I’ve two ViewControllers in my utility. One is definitely current on the Storyboard, and it has one button to open one other ViewController. The second ViewController is definitely a WKWebView that I wish to open on the button click on. Once I click on the button the WebView simply slides on prime of the primary ViewController however I would like it to open in Full display screen mode. So earlier than navigating I did attempt to set modalPresentationStyle to full display screen but it surely does not appear to work in any respect.

That is how I attempt to navigate to the WebViewViewController:

@IBAction func wkWebView(_ sender: Any) {
    if let url = URL(string: urlTextField.textual content ?? "https://www.google.com") {
        if (!urlTextField.isHidden) {
            urlTextField.endEditing(true)
        }
        let vc = WebViewViewController(url: url)
        let navVC = UINavigationController(rootViewController: vc)
        vc.modalPresentationStyle = .fullScreen;
        current(navVC, animated:true)
        }
}

That is the WebViewViewController code (I haven’t got it on my Storyboard, so I haven’t got any segue between the 2 ViewControllers ):

import UIKit
import WebKit

class WebViewViewController: UIViewController {

    personal let webView: WKWebView = {
        let preferences = WKWebpagePreferences()
        preferences.allowsContentJavaScript  = true;
        let configurtions = WKWebViewConfiguration();
        configurtions.defaultWebpagePreferences = preferences;
        configurtions.allowsInlineMediaPlayback = true;
        configurtions.requiresUserActionForMediaPlayback = false
        let webView = WKWebView(body: .zero, configuration: configurtions)
        webView.scrollView.contentInsetAdjustmentBehavior = .by no means
        return webView;
    }()
    
    personal let url: URL;
    
    init(url: URL) {
        self.url = url
        tremendous.init(nibName: nil, bundle: nil);
    }
    
    required init?(coder: NSCoder) {
        fatalError()
    }
    
    override func viewDidLoad() {
        tremendous.viewDidLoad()
        view.backgroundColor = .systemBackground
        view.addSubview(webView);
        webView.load(URLRequest(url: url));
    }

    override func viewDidLayoutSubviews() {
        tremendous.viewDidLayoutSubviews()
        webView.body = view.bounds
    }
}

How can I make the Webview ViewController to open in a fullscreen?
