I am trying to make CloudKit Web service work by following the Apple Documentation at https://developer.apple.com/library/archive/documentation/DataManagement/Conceptual/CloudKitWebServicesReference/SettingUpWebServices.html I am able to get the redirect URL from curl --location 'https://api.apple-cloudkit.com/database/1/iCloud.Wasiq.Migraine/development/private/users/current?ckAPIToken=b440efde65bb8c1f45464598470f4cc73977f2c10d6c40587588ec9f1c1c56f0' Now, with the redirect URL, if I login with Apple ID, I am expecting ckWebAuthToken Documentations says If you did not specify a custom URL when creating the API token, register an event listener with the window object to be notified when the user signs in. window.addEventListener('message', function(e) { console.log(e.data.ckWebAuthToken);}) Here's a complete SwiftUI working project to reproduce the issue import SwiftUI import UIKit import WebKit struct ContentView: View { @State private var loadWeb = false @State private var url = "" var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundColor(.accentColor) Text("Hello, world!") .onTapGesture { var request = URLRequest(url: URL(string: "https://api.apple-cloudkit.com/database/1/iCloud.Wasiq.Migraine/development/private/users/current?ckAPIToken=b440efde65bb8c1f45464598470f4cc73977f2c10d6c40587588ec9f1c1c56f0")!,timeoutInterval: Double.infinity) request.httpMethod = "GET" let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data else { print(String(describing: error)) return } do { let res = try JSONDecoder().decode(Root.self, from: data) print("Getting URL") self.url = res.redirectURL self.loadWeb = true print(res.redirectURL) } catch let error { print(error) } } task.resume() } if(!loadWeb){ Spacer() } else{ WebView(url: $url) } } .padding() } } struct Root: Codable { let redirectURL: String} struct WebView: UIViewRepresentable { @Binding var url: String func makeCoordinator() -> WebView.Coordinator { Coordinator(self) } func makeUIView(context: Context) -> WKWebView { let config = WKWebViewConfiguration() let source = "window.addEventListener('message', function(e){ window.webkit.messageHandlers.logging.postMessage(e.data); })" let script = WKUserScript(source: source, injectionTime: .atDocumentStart, forMainFrameOnly: false) config.userContentController.addUserScript(script) config.userContentController.add(context.coordinator, name: "logging") let view = WKWebView(frame: UIScreen.main.bounds, configuration: config) view.navigationDelegate = context.coordinator view.load(URLRequest(url: URL(string: url)!)) return view } func updateUIView(_ uiView: WKWebView, context: Context) { // you can access environment via context.environment here // Note that this method will be called A LOT } class Coordinator: NSObject, WKNavigationDelegate, WKScriptMessageHandler { func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) { print("message: \(message.body)") // and whatever other actions you want to take } let parent: WebView init(_ parent: WebView) { self.parent = parent } }} When I tap on "Hello, World", the WebView gets loaded and asks the user to Sign in with Apple ID. After logging in, I do not see the ckWebAuthToken getting printed Instead I see the following output message: SOAuthorizationDidStart message: { authorization = { "grant_code" = "ce619474218c0485182af8cf019684d2e.0.sruq.i5r0nMCZIKVEBma6p6FE5Q"; "id_token" = ""; state = "auth-sznjvrn0-6svd-pw2c-lwfy-47rd7n64"; }; event = AppSSOTakeoverDidComplete; user = { };} message: { event = WidgetBridgeComplete; state = "auth-sznjvrn0-6svd-pw2c-lwfy-47rd7n64";}
