Simplest webview app in iOS - fail to run - ios

Question

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:
Create new project->iOS App --> (see image below)
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))
}
}
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()
}
}
}
