Simplest webview app in iOS - fail to run

I am trying to make an ios app that simply open a URL. So basically a webview app. I am using XCode 12.4 and that's what I did:

1. Create new project->iOS App --> (see image below)
2. Create a new file: ViewController.swift -->

import WebKit
class WebViewController: UIViewController, WKNavigationDelegate {

    var webView: WKWebView!
    
    override func loadView() {
        webView = WKWebView()
        webView.navigationDelegate = self
        view = webView
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        let url = URL(string: "https://developer.apple.com")!
        webView.load(URLRequest(url: url))
    }
}

4. Build and Run.

The issue is that the app continues to open on "Hello World" and I imagine the reason is that the MyappApp.swift file is calling ContentView instead of ViewController

import SwiftUI

@main
struct myappApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

How can I fix this?

Disclaimer: This is my first iOS app and I know little to nothing about iOS dev.

You are very close... Wrap your WebViewController in a UIViewControllerRepresentable to make it compatible with SwiftUI

import SwiftUI
struct WebView_UI: UIViewControllerRepresentable {
    func makeUIViewController(context: Context) -> some UIViewController {
        let vc = WebViewController()
        return vc
    }
    func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {
        
    }
}

And then reference your new SwiftUI UIViewControllerRepresentable in a SwiftUI struct. For example...

struct myappApp: App {
    var body: some Scene {
        WindowGroup {
            WebView_UI()
        }
    }
}

Or...

struct ContentView: View {
    var body: some View {
        VStack{
            Text("Hello World!").padding()
            WebView_UI()
        }
    }
}
