I know how to set up a parental gate to keep a child user away from a web portal for parents or guardians. But is it even OK with Apple (or just in general) to open a browser from inside a kids app? I can think of two ways to do this: Launch a browser with UIApplication.shared.open(). This takes the user (presumably an adult) out of the app. Will Apple object to this? Use an in-app browser with WKWebView. (Wrapped in UIViewRepresentable because I'm using SwiftUI.) Option 2 has some problems with Google SSO, which is a requirement for me. Some details in stackoverflow 2016 and stackoverflow 2019 and gitHub. I can't figure out how to apply the solutions in those posts to the SwiftUI architecture or even the UIViewRepresentable.

So I am trying to control the wkwebview content within my app. When I try the following code> var backButton: some View { Button(action: { webView.goBack() // Add your back button action here }, label: { Image(systemName: "arrow.uturn.backward") .font(.title) }) .navigationBarBackButtonHidden(true) } I get webView out of scope. This is how I have webView implimented struct WebView: UIViewRepresentable { let url: URL let preferences = WKPreferences() let useragent = WKWebViewConfiguration() func makeUIView(context: Context) -> WKWebView { @State var webView = WKWebView() let request = URLRequest(url: url) useragent.applicationNameForUserAgent = "Version/1.2 LavaRock/1.2" useragent.allowsAirPlayForMediaPlayback = true useragent.allowsInlineMediaPlayback = true useragent.allowsPictureInPictureMediaPlayback = true // preferences.isFraudulentWebsiteWarningEnabled = true preferences.isSiteSpecificQuirksModeEnabled = true preferences.isElementFullscreenEnabled = true webView.allowsBackForwardNavigationGestures = true // webView.configuration.allowsPictureInPictureMediaPlayback = true webView.customUserAgent = "Mozilla/5.0 (iPhone; CPU iPhone OS 18_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148 Version/1.2 LavaRock/1.2" webView.load(request) return webView } func updateUIView(_ uiView: WKWebView, context: Context) { // Handle view updates if needed } } How should create the button?

Hi, I'm working on a web project that uses the MediaSession API to interface with the media notification on iOS. The issue that I'm experiencing occurs after pressing the play button in the media session modal where the session seems to NOT fire the event handler callback and also kill the media session itself. It's a strange behaviour considering that the pause callback works fine. audio_source = new Audio(url); navigator.mediasession.metadata = { ... // Metadata here }; navigator.mediasession.setActionHandler('play', (details) => { audio_source.play(); } ); navigator.mediasession.setActionHandler('pause', (details) => { audio_source.pause(); } );

There is a 'WebCore::CachedResource::removeClient(WebCore::CachedResourceClient&)' crash in iOS 18 version. Could you please tell me if there are any changes to the WebView regarding this crash and how to debug it?

Has anyone attempted to render a WKWebView in a background or invisible UIView so that it’s visible immediately upon first presentation, and if so, what technique did you use? Background: We are trying to embed a WKWebView in our UI that renders seamlessly next to native UI. We are going to download a .ZIP file, unzip it locally to disk, and then point the WKWebView to that local file. However, when testing this solution on an iOS simulator (running iOS 17.5), we see a flash of white – specifically there is no content rendered for the first moment or two, followed by content appearing. We have tried attaching the WKWebView to the UIWindow, adding a javascript callback for the onReadyStateChange “loaded” event, and then only proceeding to present our UIViewController containing our WKWebView afterwards, but we still see a moment with no content being rendered at all. If we add a delay using DispatchQueue.asyncAfter of approximately one second (anything less still flashes), our content does seem to be correctly rendered in the background and immediately visible when the UIViewController gets presented. This is a problem that was originally asked nearly 11 years ago (https://stackoverflow.com/questions/15669809/how-to-prevent-initial-white-flash-when-showing-a-uiwebview); and the agreed upon solution there seems to be to set the background to be not opaque, but the issue remains that the content isn’t immediately visible. Google Gemini and ChatGPT have proposed a number of solutions, including hallucinations about headless WKWebView support on iOS, but unfortunately we are unable to achieve a solution without a DispatchQueue delay with a magic number.

navigator.permissions.query -> permissionStatus.onchange is Supposed to listen to the event of a change in permissions in the browser settings. This works for all browsers, but in Safari for iOS and MacOS this seems to be broken in the currently recent versions 17.x Example: navigator.permissions.query({ name: 'notifications' }).then((permissionStatus) => { permissions = permissionStatus.state; // this value gets set correctly permissionStatus.onchange = () => { // This will not get executed when permissions have been changed // within the safari settings app, or iOS Settings for PWA or Safari }; }); Can someone from Apple's Webkit Team please comment on this? Thank you. T.

When you have a blank Safari new tab open, the browser.tabs.query API inaccurately includes those tabs in results that include a url or title in the query options. To reproduce, open several tabs, and a blank new tab. Open the background page devtools, and execute the following command: browser.tabs.query({url: 'https://github.com/'}, console.log) In addition to any potentially valid results (if you have github.com open, for example), there will also be an entry for the blank tab, which has an empty, non-matching URL. Tab { active: true, audible: false, height: 1095, highlighted: true, id: 6, incognito: false, index: 3, isArticle: false, isInReaderMode: false, mutedInfo: {muted: false}, pendingUrl: "", pinned: false, status: "complete", title: "", url: "", width: 1792, windowId: 1 } I hope that this bug can be addressed, as it causes some unexpected behavior.

Hi, we have really weird issue with one of our website embedded into iOS app using WKWebView. The website has CSRF mechanism implemented and is using some AJAX calls when user interact with it and in response some cookies are returned. Then the JS code wants to access these cookies to set proper value for next request header. Unfortunately when using document.cookie JS command these cookies are not there. However they are sent within another requests and I can see them from Safari Developer Inspector connected to my device or iOS Simulator. Another interesting thing is that the same website and solution works fine on Safari browser and with SFSafariViewController displayed inside our app. We've tried using various things for WKWebView configuration like nonPersistent data store, but without success. Does anyone have any idea how to deal with such issue and why it doesn't work with WKWebView?

We're developing an application using location feature in WKWebView. When accessing a URL that uses location information from WebView, a dialog box saying " Would Like To Use Your Current Location - Don't Allow or OK". If "Dont allow" is selected multiple times, the dialog will disappear and the location setting for that URL will be fixed as "Don't Allow". In Safari, I can change that location settings for each URL, But Application's WebView does not have such settings UI. How do I clear or change the setting so that location information is no longer available? It seems that reinstalling the application will clear the WebView location settings.

I'm working on a web browser App that's distributed via the App Store. This app renders web pages using WKWebView. Our users are requesting a way for us to allow them to play videos in Picture in Picture. After some investigation, we noticed that in order to allow PiP videos in our browser in the sandboxed environment, we need to add the com.apple.PIPAgent entitlement under the com.apple.security.temporary-exception.mach-lookup.global-name option. We tried to submit our app with this entitlement, but unfortunately, we were rejected: Guideline 2.4.50) - Performance We've determined that one or more temporary entitlement exceptions requested for this app are not appropriate and will not be granted: com.apple.security.temporary-exception.mach-lookup.global-name com.apple.P|PAgent We would like to have access to this entitlement so we can offer PiP to our users. We already created a radar about this as well: FB13814428 Additionally, we have another radar (FB13557716) regarding allowing the usage of a private flag _allowsPictureInPictureMediaPlayback, which would also be required to enable us to use PiP. Is there any way in which we can currently enable PiP? Would opening a TSI help here?

Issue Summary: I have encountered an issue where JavaScript does not execute in a WebView when another UIViewController is presented modally with modalPresentationStyle.fullScreen. This problem only occurs on physical devices running iOS 17.5.1. The issue is not present on iOS 17.5 simulators or devices running iOS 17.4.1 or earlier. Reproduction Steps: Create a ViewController with a WebView. Load a web page (e.g., https://apple.com) in the WebView. Present another ViewController modally with modalPresentationStyle.fullScreen. Verify that JavaScript execution in the initial WebView stops working. Test Code: import UIKit import WebKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Set up the WebView let configuration = WKWebViewConfiguration() let webView = WKWebView(frame: view.frame, configuration: configuration) view.addSubview(webView) webView.frame = view.frame if #available(iOS 16.4, *) { webView.isInspectable = true } else { // Fallback on earlier versions } webView.load(URLRequest(url: URL(string: "https://apple.com")!)) } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) let navigationController = UINavigationController(rootViewController: TargetViewController()) navigationController.modalPresentationStyle = .fullScreen present(navigationController, animated: true) } } class TargetViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Set up the WebView let webView = WKWebView(frame: view.frame, configuration: WKWebViewConfiguration()) view.addSubview(webView) webView.frame = view.frame if #available(iOS 16.4, *) { webView.isInspectable = true } else { // Fallback on earlier versions } webView.load(URLRequest(url: URL(string: "https://apple.com")!)) } } Observations: The JavaScript within the WebView stops executing only on physical devices running iOS 17.5.1. This issue does not occur on the iOS 17.5 simulator. Devices running iOS 17.4.1 or earlier do not experience this issue. Request for Assistance: Could you please provide any insights or potential workarounds for this issue? Additionally, if this is a known bug, any information on upcoming fixes would be highly appreciated. Thank you.

I created a Xcode project to test the DNR updateDynamicRules API performances on Safari (MacOS). https://github.com/radiolondra/TestUpdateDynamicRules Following the instructions in the README file, it's possible to test the extension on Chromium and Firefox browsers (on Windows). The project uses 2 json files containing static rules, enabled by default in the manifest file. These static rules are automatically installed in the browser when the extension is installed. Using the extension popup it is possible to add/remove just one very simple dynamic rule in the browser, a rule that acts on a predefined test domain (https://iana.org). What we want to measure is the time it takes for each browser to add/remove that one dynamic rule. The results for Safari are unacceptable to say the least: Safari: from 6000 to 8000 MILLISECONDS (6/8 seconds!) <<<<<<<<< Chrome: from 5 to 6 MILLISECONDS Firefox: from 5 to 7 MILLISECONDS Notice the time needed by Safari... It would be a good idea to take a look at this monstrosity. Thanks.

My Safari Web Extension uses a service worker and an IndexedDB database (IDB). For what hidden reason or perverse logic when deleting the Safari history all service workers are brutally shutted down and the database emptied of all its contents? And I heard about local storage too... It happens all the time in Safari macOS and iOS. Safari is the only browser in the world that takes the liberty of deleting what it shouldn't. Good Job indeed.

Preamble: I am creating an iOS build of a Ren'Py game. My coding experience with Swift/ObjC is nearly nonexistent and I've primarily followed tutorials up to this point. Ren'Py uses an underlying framework to create an Xcode project. I do not have control over how this framework does things, but I can add files before actually compiling inside Xcode. I MUST use the pyobjus library to do so based on my current understanding, abilities, and frameworks. The included IAPHelper class processes in-app purchasing and it works great! The following function indicates, however, that there is a rootViewController that I need to attach to. - (void) showDialog { if (alert != nil) { return; } alert = [UIAlertController alertControllerWithTitle:self.dialogTitle message:nil preferredStyle:UIAlertControllerStyleAlert ]; UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleLarge]; // Adjust the indicator so it is up a few pixels from the bottom of the alert indicator.center = CGPointMake(alert.view.bounds.size.width / 2, alert.view.bounds.size.height - 50); [indicator startAnimating]; [alert.view addSubview: indicator]; #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wdeprecated" [UIApplication.sharedApplication.keyWindow.rootViewController presentViewController:alert animated:YES completion:nil]; #pragma clang diagnostic pop } Problem: I am TRYING to implement an in-app browser for Patreon authentication purposes. The files I have put together are as follows: BrowserViewController.h // BrowserViewController.h #import <UIKit/UIKit.h> #import <WebKit/WebKit.h> @interface BrowserViewController : UIViewController - (void)loadURL:(NSString *)urlString; @end BrowserViewController.m // BrowserViewController.m #import "BrowserViewController.h" @interface BrowserViewController () @property (nonatomic, strong) WKWebView *webView; @end @implementation BrowserViewController - (void)viewDidLoad { [super viewDidLoad]; self.webView = [[WKWebView alloc] initWithFrame:self.view.frame]; [self.view addSubview:self.webView]; NSLog(@"viewDidLoad"); } - (void)loadURL:(NSString *)urlString { NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:request]; NSLog(@"loadURL"); } @end OAuth2Strategy.py init python in auth: from urllib.parse import urlencode, urlparse, parse_qs from urllib.request import urlopen, Request import ssl import certifi from store import webserver, OpenURL import json class OAuth2Strategy(): def __init__(self, authorization_url, token_url, client_id, client_secret, callback_url, scope): self.authorization_url = authorization_url self.token_url = token_url self.client_id = client_id self.client_secret = client_secret self.callback_url = callback_url self.scope = scope self.on_success_callback = None self.on_fail_callback = None def run(self, on_success_callback = None, on_fail_callback = None): self.on_success_callback = on_success_callback self.on_fail_callback = on_fail_callback webserver.start(self) if renpy.renpy.ios: from pyobjus import autoclass, objc_str # Import the Objective-C class BrowserViewController = autoclass('BrowserViewController') # Create an instance of the BrowserViewController browser = BrowserViewController.alloc().init() # Load a URL url = self.make_authorize_url() browser.loadURL_(objc_str(url)) elif renpy.renpy.android: pass else: renpy.run(OpenURL(self.make_authorize_url())) def make_authorize_url(self): return self.authorization_url + "?client_id={client_id}&scope={scope}&redirect_uri={redirect_uri}&response_type=code".format( client_id=self.client_id, scope=self.scope, redirect_uri=self.redirect_uri, ) @property def redirect_uri(self): return "http://127.0.0.1:" + str(webserver.PORT) + self.callback_url def handle_auth(self, request): parsed_path = urlparse(request.path) query = parse_qs(parsed_path.query) code = query.get("code") if not code: request.send_response(400) request.send_header('Content-type', 'text/html') request.end_headers() request.wfile.write(b'Failed to authenticate.

When I run my app and click the button that SHOULD spawn the browser, nothing happens. I can see that my URL is getting pushed to the function in the log along with Warning: -[BETextInput attributedMarkedText] is unimplemented and Failed to request allowed query parameters from WebPrivacy. though my admittedly light research indicates this isn't an issue. I have a feeling I'm not attaching my webView to the right hierarchy but I'm not sure exactly what I'm doing wrong.

Hello, I'm Trying to learn swift and looking for resources to learn swift UI and try to create a basic web browser app for ios and mac. (using webkit). Does anyone have any type of tips and tricks to perform this? Thank you ahead of time.

I'm experiencing an issue with WKWebView and localStorage. I've set up a standard WKWebView with the configuration: configuration.websiteDataStore = WKWebsiteDataStore.default() Everything works fine in the emulator (iOS 16.x, 17.0), but on my iPhone 13 running iOS 17.4, I encounter a problem. When I set a localStorage value on my local HTML page, navigate to another URL within the webview, and then return to the original page, the localStorage is cleared. This behavior is new and wasn't happening before. Has anyone else encountered this or have any suggestions on how to fix it? The localstorage should be persistent as it always has been.
