Web AR stopped working after the IOS 18.4 update for iPad gen9
So I have web Augmented Reality apps hosted on AWS S3. It worked fine for a month, but as soon as the IOS 18.4 update was installed they stopped working. It works on every other device and IOS versions. The URLs for the mentioned AR experiences: digitechonline.in/solsprefimaginewt8/ digitechonline.in/solsprefimaginewt8p2/ digitechonline.in/orocarear/ These AR experiences get stuck on the loading screen and either reload or give an error. Ideally the camera is supposed to open. I have tested it on Safari, Microsoft Edge and Google Chrome browsers. They were created through Unity webgl and hosted on AWS S3 bucket. Please provide a quick solution to this.

Tracking playback events from Apple Podcasts iframe in AEM
Hi everyone, I’m working on a web project developed on Adobe Experience Manager (AEM), where we’ve built a custom component that embeds Apple Podcasts episodes using the official iframe provided via https://embed.podcasts.apple.com. Everything works correctly from a rendering point of view, but we are now exploring ways to track user interactions with the embedded player, specifically events such as: start, play, pause, progress milestones (e.g. 25%, 50%, etc.). This data would be used to send analytics events to Adobe Analytics. So far, we haven’t found any documentation or JavaScript API that would allow us to listen to these events. We'd like to ask: Is there any official way to track playback events from an Apple Podcasts iframe? Any information, clarification, or direction would be really appreciated. Thanks in advance! Thanks, Adriana

Video on Safari iOS - UI/UX of Shadow Content User Agent
Hi, when I display an HTML page with a on Safari iOS, I get a nice UI. Great! At the first look I see a video frame with an arrow-in-a-circle button in the middle. Very nice. I click on the arrow and I get a fullscreen view while the video begins to play. I watch the video then I pause it then I click on the top-left x button. So I go back to my html page and the video is perfectly there as it was before. But, there is an annoying new detail. The video frame is really dark, it still presents all the controls and a "different" arrow button to play it again. In other words that nice video-frame, that nice picture, is not longer visible on the page. That nice page with nice pictures has now an almost-black rectangle. Too bad. Sure I can click on the video (outside the controls) then the controls and the black overlaying frame disappear. I can see that nice picture again. Finally. Well, but the arrow-in-a-circle button to play the video disappeared. Now the user cannot longer understand that's a video to play. It looks just like any other pictures to admire statically. Is any way to get the previous first look of the video? The one clear, with the current frame and the arrow-in-a-circle look?

Detecting tabs change in Safari App Extension when switching windows inside validateToolbarItem.
Hi. I'm a developer of Tab Finder (https://apps.apple.com/us/app/tab-finder/id6741719894) My problem is that every time i switch from my first window to a second window, the tabs in the validateToolbarItem() are INcorrect on a first call, but when I switch back from the second window to my main window, the tabs are CORRECT even on a first call. To demonstrate it, i recorded a video: https://youtu.be/RwskzrSJ8u0 To run the same sample extension from the video, you can get the code from this GitHub repo: https://github.com/kopyl/test-tabs-change Its only purpose is to log URLs of an active page of all tabs. The SafariExtensionHandler's code of the sample app is very simple: import SafariServices func printOpenTabsHost(in window: SFSafariWindow) async { let tabs = await window.allTabs() log("Logging tabs for a new window: \(window.hashValue)") for tab in tabs { let page = await tab.activePage() let properties = await page?.properties() let url = properties?.url log(url?.absoluteString ?? "No URL") } } class SafariExtensionViewController: SFSafariExtensionViewController { static let shared = SafariExtensionViewController() } class SafariExtensionHandler: SFSafariExtensionHandler { override func validateToolbarItem(in window: SFSafariWindow, validationHandler: @escaping ((Bool, String) -> Void)) { Task { await printOpenTabsHost(in: window) } validationHandler(true, "") } override func popoverViewController() -> SFSafariExtensionViewController { return SafariExtensionViewController.shared } } Could you please tell if i'm missing something and how to see the actual tabs inside the overridden validateToolbarItem call of the SafariExtensionHandler (or in any other way, I'm okay with any implementation as long as it works).

Handling POST-based Authentication Flow with ASWebAuthenticationSession and MDM Client Certificate
Hello, I have an authentication flow where my app communicates with a backend protected by F5 client certificate validation. The client certificate is distributed via MDM and is available in the device keychain, but not accessible directly from the app. When using ASWebAuthenticationSession (or SFSafariViewController) Safari can successfully pick up and present the certificate during authentication, so that part works fine. However, the backend’s authenticate endpoint only supports a POST request with an Authorization header, whereas ASWebAuthenticationSession only accepts a GET URL when starting the session. My questions are: How is this type of flow typically implemented in iOS? Should the backend provide a GET-based endpoint that redirects into the POST, or is there a recommended iOS pattern (e.g., an intermediate HTML page that does the POST after certificate validation)? Are there Apple guidelines on handling certificate-based auth with ASWebAuthenticationSession when the API requires POST, especially for In-House distributed apps? Any guidance or best practices would be very helpful.

Getting started with PHP ..
I am new to PHP. I have developed my own web site with a lot of javascript in simple HTML files. I want to do some extensions with PHP but I can't make a simple web page function. I am sure something simple is wrong. Help! Here is the test web page I made: hello.html <html>  <head>   <title>Hello World</title>  </head>  <body>   <?php echo 'Hello World!'; ?>  </body> </html> Pointing Safari at hello.html gives me a new tab with the correct title, but no "Hello World" in the page itself. Here is the output of php --version: WARNING: PHP is not recommended PHP is included in macOS for compatibility with legacy software. Future versions of macOS will not include PHP.

Issue with Copy Functionality in WKWebView Using Mac Catalyst
Hello, I am developing a Mac application via Mac Catalyst and encountering an issue with WKWebView. Specifically, I'm loading a webpage (e.g., https://translate.google.com) in WKWebView, but when I press the copy button on the page, the content doesn't actually copy to the clipboard. I've attempted modifying the UserAgent without any success. Here is the relevant part of my code: override func viewDidLoad() { super.viewDidLoad() let config = WKWebViewConfiguration() config.preferences = WKPreferences() config.defaultWebpagePreferences.preferredContentMode = .desktop let webView = WKWebView(frame: .zero, configuration: config) webView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(webView) webView.scrollView.showsVerticalScrollIndicator = false webView.backgroundColor = UIColor.white webView.scrollView.backgroundColor = UIColor.white webView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true webView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true webView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true webView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true if let url = URL(string: "https://translate.google.com") { let req = URLRequest(url: url) webView.load(req) } }

Password input remains visible after dismissing “Use Strong Password?” dialog
When the “Use Strong Password?” dialog appears and I select “Not Now” to manually enter my own password, the password I type is displayed in plain text instead of being masked. Since the input field is of type="password", the entered characters should be hidden as is standard for password inputs. Is there a way to prevent this behavior and ensure that the password is properly hidden even after dismissing the strong password suggestion dialog?

[iOS 26 Beta] event.target.value is always empty — only from specific script domains
Hey everyone, After installing iOS 26 beta, I started noticing unexpected behavior in our input event handlers. Specifically, when users type into an field, event.target.value is always an empty string — but only when the JS file is loaded from a specific domain (e.g., t1.daumcdn.net). The exact same code works perfectly when hosted on other domains like t2.daumcdn.net or search1.daumcdn.net. 👉 I created a demo here: 🔗 https://codepen.io/bzasklcu-the-sans/pen/rNXogxL The scripts loaded from each domain are 100% identical (apart from the top-level selector). Before iOS 26 beta, this worked fine. I suspect this is related to ITP or some new cross-origin behavior in Safari, but I’d love to know if anyone else is running into this — or if someone knows a workaround. Thanks!

How to inspect WKWebExtension with a extension service worker
iOS 18.4 introduces the new WKWebExtension API to support extensions in WKWebView. However, for extensions that have migrated to Manifest V3 and use an extension service worker as the background script, it's currently not possible to inspect them through Safari. This is only thing I can see, I don't know how to inspect the details of the "background.js" I'm wondering—has this changed? Is it now possible to inspect extension service workers?

Guidance Needed: Safari ITP's Link Tracking Protection Impacts Legitimate App Functionality
Area: WebKit (Safari) Description: I am reporting an issue where our application's core functionality is being broken by Safari's Intelligent Tracking Prevention (ITP). ITP's "Link Tracking Protection" feature automatically strips specific query parameters from URLs. We understand this is an intentional privacy feature. However, our application requires these query parameters to carry essential, non-tracking data, such as authentication tokens or specific app-state information to function correctly. When a user navigates to our site, Safari strips these parameters, this means our client-side application never receives the necessary data, which breaks core features and leads to a failed user experience. This is a significant issue for our application as it prevents users from accessing their content. We are seeking guidance on how to resolve this. Questions for Apple: Is there a recommended way to identify and flag essential, non-tracking query parameters so that Safari's ITP does not strip them? Our parameters are critical for app functionality, not for third-party tracking. What is the recommended best practice for building web applications that rely on URL parameters while adhering to ITP's privacy-first model? We want to ensure our application is compatible with modern browser privacy features without compromising functionality. Could you provide a detailed explanation of what criteria ITP uses to decide which parameters to strip? Understanding the underlying logic would help us restructure our URLs to avoid this issue. Device Information: Operating System: iOS and macOS Safari Version: Latest stable versions on both platforms Device Models: All relevant models and device types
