WebKit Loading problem

I'm tired of opening up safari to open developer.apple.com so I'm trying to embed the website into an app, but sth is definitely wrong. It's been loading for ten mins and is still white. here's the code

import SwiftUI
import WebKit
import UIKit

struct WebViewPage : UIViewRepresentable {
    func makeUIView(context: Context) -> WKWebView  {
        return WKWebView()
    }
    func updateUIView(_ uiView: WKWebView, context: Context) {
        let req = URLRequest(url: URL(string:"developer.apple.com")!)
        uiView.load(req)
    }
}

#if DEBUG
struct WebViewPage_Previews : PreviewProvider {
    static var previews: some View {
        WebViewPage()
    }
}
#endif

app delegate:

import SwiftUI

@main
struct Developer_WebpageApp: App {
    var body: some Scene {
        WindowGroup {
            WebViewPage()
        }
    }
}
