How to Display a Web Application with Basic Authentication in WKWebView using SwiftUI (iOS)

This article shows how to display a web application with basic authentication in WKWebView using SwiftUI.

Source Code

This source code was made with reference to "WKWebView with Basic auth" and "Using WebKit Delegates".

ContentView.swift

import SwiftUI

struct ContentView: View {
    var body: some View {
        WebViewTest()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

WebViewTest.swift

import SwiftUI
import WebKit

struct WebViewTest: UIViewRepresentable {
    func updateUIView(_ uiView: WKWebView, context: Context) {
        //
    }

    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }

    var url: String = "https://hogehoge.hoge"

    func makeUIView(context: Context) -> WKWebView {
        let view = WKWebView()
        view.navigationDelegate = context.coordinator
        view.load(URLRequest(url:URL(string: url)!))
        return view
    }

    class Coordinator: NSObject, WKNavigationDelegate {
            let parent: WebViewTest

            init(_ parent: WebViewTest) {
                self.parent = parent
            }

        func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge,
                         completionHandler: @escaping(URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
                let credential = URLCredential(user: "The user name to Basic Auth.",
                                               password: "The password to Basic Auth.",
                                               persistence: .forSession)
                completionHandler(.useCredential, credential)
            }
        }
}

struct WebViewTest_Previews: PreviewProvider {
    static var previews: some View {
        WebViewTest()
    }
}

The Result

I cannot show you the contents of the web application. But I guess that you can check that all contents (text and images) are loaded.
