I’m encountering an issue with a Safari extension bundled with our main application (F-Secure). The extension is not appearing consistently in Safari settings on a customer’s iPad running iOS 18.3. Below are the details of the issue: Issue Description The Safari extension is bundled with the main app (F-Secure). After installing the app, the extension should automatically appear in Settings > Safari > Extensions, where the user can enable it. On the customer’s iPad, the extension is missing from the Safari settings. It briefly appeared once but then disappeared again.

WKWebView has a new property "isBlockedByScreenTime" since iOS 26. But I do not yet understand when exactly this property could be used. When I setup content-based restrictions in the ScreenTime settings then WKWebView reports an error 105 via "webView:didFailProvisionalNavigation:" delegate. The isBlockedByScreenTime property still returns false in this case. If ScreenTime has a time-based limit, the App would not run at all. Under which circumstances would the property "isBlockedByScreenTime" return the value true? When exactly and for what can this property be actually used? The "problem" is that I want to find if a web page is blocked and can not be loaded, why this is the case. By simply trial and error I found out that WKWebView returns error codes 104 and 105 for blocked web sites because of content filters and Screen Time restrictions, however these error codes are not documented at all (at least I've not found any documentation or documentation for these error codes and also some other codes like 100, 102, 204 etc), so I'm not really sure if I handle all cases correctly. I hoped that isBlockedByScreenTime would at least tell me one reason for blocked pages. If there are documents which explain these error codes (100 and above), where I can find these?

We are seeing an issue in Safari on iOS 26 where the a automatic unfocus of on select box dismisses the second one. <select name="choice1" onblur="console.log('onblur1');" onfocus="console.log('onfocus1');"> <option value="first">First Value</option> <option value="second" selected>Second Value</option> <option value="third">Third Value</option> </select> <select name="choice2" onblur="console.log('onblur2');" onfocus="console.log('onfocus2')"> <option value="first">First Value</option> <option value="second" selected>Second Value</option> <option value="third">Third Value</option> </select> select something in choice1. quickly tap choice2 before onblur1 is logged. At the timing of onblur1 the selection menu for choice2 is dismissed. Anyone know how to fix this behavior?

Hello all, As you may know, the company ProofPoint is an Apple partner, and is engaged (I think) to reduce misuse of icloud emails. We have two servers solely set up for our web-app, which is a specialised forum for apartment owners. The new servers were established about the same time, with the same provider, with clean new IP addresses - and as mentioned above, are only used for this web-app. During a testing phase a YEAR ago, we became aware that our in-house icloud emails weren't receiving notifications via the app, and further investigations revealed that the cause was that ProofPoint had placed a block on that server's IP. We immediately, via their website form initiated a Support Ticket, which, the site indicated was lodged, BUT we have never received any response to that Ticket, nor have we received any response to four subsequent Tickets we initiated - nothing. In over a year!! Yesterday, we contacted Apple support, but the devices area of support is the main section and they said it wasn't an issue they could assist with. Some relevant matters: SPF: DKIM: DMARC: are, I believe all configured correctly (and Gmail gives a PASS to all of them). The IP is not blacklisted by any list we are aware of. Our other server's IP isn't blocked by ProofPoint. So, literally at wits end, I'm reaching out to the developer subscribers here to see if they have any suggestions for us. We currently are unable to accept any new subscriber that is using an icloud email address, and that's an absurd situation to be in. Surely we don't have to go to the trouble and inconvenience of obtaining a new IP because of this!!! But when we can't get ANY response to the Support Tickets, it's really hard. Thanks

I'm building a macOS Google Chrome extension. I need to be able to send messages from the Chrome extension to the macOS app What's the set up flow? I've heard about native messaging, but I struggle to implement it. I've heard about XPC, but not sure JS can send messages to a macOS XPC service.

Hello, In iOS 26 beta, we are seeing an unexpected behavior when using SwiftUI WebView (or a custom WKWebView via UIViewRepresentable). When an alert is presented above the WebView, the WebView immediately reloads to its initial page. The alert itself also disappears instantly, making it impossible for the user to interact with it. This issue occurs both with the new SwiftUI WebView / WebPage API and with a wrapped WKWebView. The problem was not present in previous iOS versions (iOS 17/18). Steps to reproduce: Create a SwiftUI view with a WebView (pointing to any URL). Add a toolbar button that toggles a SwiftUI alert. Run the app on iOS 26 beta. Tap the button to trigger the alert. Expected behavior: The WebView should remain as-is, and the alert should stay visible until the user dismisses it. Actual behavior: As soon as the alert appears, the WebView reloads and resets to the initial page. The alert disappears immediately. Minimal Example: struct ContentView: View { @State private var showAlert = false var body: some View { NavigationStack { WebView(URL(string: "https://apple.com")!) .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Close") { showAlert = true } } } .alert("Confirm close?", isPresented: $showAlert) { Button("Cancel", role: .cancel) {} Button("Close", role: .destructive) {} } } } } I'm using Xcode Version 26.0 beta 7 Thanks for your help.

How can i add Authorization header to a wkwebview. I checked https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 which says Authorization header is a reserved http header and shouldn’t be set. I want to set it when requesting a url in wkwebview for authentication purpose?

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?

"The Referer header allows a server to identify referring pages that people are visiting from or where requested resources are being used. " This header is never forwarded to server when the user is browsing the website in a WebView. This is properly maintained by other browsers but not in-app. How do I include it?

Hello, I am experiencing an issue when trying to open the browser on my Apple Watch SE 2 running the latest version, watchOS 11.6. When I attempt to visit any website, the browser opens and displays the URL at the top as if it is loading, but the screen remains black and no content is displayed. The internet connection is available, and all other apps on the watch work normally. This issue occurs only with the browser. I would appreciate any guidance or solution to resolve this problem. Thank you for your assistance.

Hello, We’ve been using the CesiumJS WebGL library for several years, both on our website and within embedded WebViews in our iOS application. Since upgrading to iOS versions 18.2 and 18.3, we’ve started receiving numerous user complaints regarding application crashes on various iPad and iPhone models when loading CesiumJS. The crashes occur as soon as the 3D view initializes, and the error consistently reported is: "WebGL context lost" This issue appears to be a WebGL-related crash potentially triggered by GPU memory handling or allocation limits. However, we are not detecting any abnormal memory consumption prior to the crash, and the same setup works perfect on older iOS versions and on all Android devices and versions. Steps to Reproduce: Open: https://www.flightradar24.com/30.47,-94.84/8 Click on any aircraft icon on the map. In the aircraft details panel at the bottom, click on the “3D view” tab. On iOS 18.2 or 18.3, the page will crash shortly after initializing CesiumJS WebGL. Affected Devices: This issue is occurring across a wide range of devices, including: iPad 9th Generation iPad Pro (11-inch, 2nd Gen) iPhone SE (2020 and 2022) iPhone 11, 11 Pro iPhone XR iPhone Mini All of the above are running iOS 18.2 or 18.3. The problem does not occur on Android or previous iOS versions. Request: Has anyone else encountered similar issues with WebGL context loss after upgrading to iOS 18.2 or 18.3? Are there any known changes in memory limits or WebGL behavior in these recent iOS updates? We’d appreciate any insight or suggestions on workarounds or potential fixes. Thank you!

Problem As the title says, Safari lost all my tabs once I updated to macOS 15.4. I do of course have "Safari opens with: All windows from last session" set. This has been my default for many years. Past Mitigation In the past I had a script that I could use to backup ~/Library/Safari that would save all my bookmarks and tabs. Unfortunately they made this method of backup non-function sometime around when tab groups were introduced. Suggestion Fortunately my tab groups are still intact. But this sort of problem doesn't give me a lot of confidence. I haven't had something like this happen in a while, but when it does happen, it's quite frustrating. Apple really needs to recognize that this sort of thing can and will happen and they should make it easier for users to manually save/restore their tabs. Problem with forums To add insult to injury, as I was typing this message in the forum, I decided to select "Edit Bookmarks"... which proceeded to replace the current window with my bookmarks, thereby losing my post! It did this without warning of page content changes (which I get from most other websites). I felt somewhat relieved that the forum had recognized a previous draft and offered for me to continue. However, when I selected it, it brought me back to an old post... that was actually posted! smh

Hello, Recently, there is an issue in my service that after typing korean at input element, first click event is not working. But i knew that other services are also having same problem. It happens only on Safari. Could you guys check this issue? Thank you.

I recently updated my iPhone 12 to iOS 26. It seems there is a bug rendering Safari unable to "add to home screen" any website. Clicking the button displays a blank modal with Add button greyed out.

I'm developing an application that needs smooth framerates within a wkwebview that interacts with native code. However, requestAnimationFrame by default is still throttled to 60hz even if all my target devices (the iPad Pro for example) have supported 120hz for a long time already. I noticed that the latest Safari in 18.3 beta supports unlocked framerates, but that's only under Safari feature flags. To my knowledge, these flags do not apply to WKWebView. Is there a way to enable unlocked framerate in WKWebView via requestAnimationFrame? (Calling JS at a faster rate from the native code side will not work, almost definitely, since WKWebView will still render at its own rate.) This is an experimental application for internal use and I'm okay if there are temporary beta solutions available.

Our service includes the Apple web login feature to support "Sign in with Apple" on iOS 12. However, at some point, an error started occurring on the Apple login page in iOS 12, preventing users from proceeding further. Upon checking the Web Inspector console, we found the following error: Failed to load resource: the server responded with a status of 503 (Service Temporarily Unavailable) Please help us resolve this issue so that users can continue using "Sign in with Apple" on iOS 12.

Up until some point relatively recently, I have been able to use Safari's web inspector to connect to the iOS simulator in order to debug our web application in development at http://localhost:8088. Now, the web inspector still OPENS, but it opens in a broken state. The context is available to select from Safari's "Develop" menu: Develop > "iPhone 16 Pro (Simulator)" > "localhost - login". It appears under the Safari heading if I have navigated to the web app in the browser, or under the Expo heading if I am accessing it through the webview in our React Native wrapper app. When I select it, the web inspector window does appear. However, once it opens, the Elements pane is empty, the Console pane is empty, expressions entered into the console are not evaluated, there's no content in Sources, Network, Storage, etc. Important notes: This broken state happens at http://localhost:8088 as well as http://127.0.0.1:8088, and it seems that the insecure context is the issue. The web inspector DOES work for HTTPS sites. If I navigate to, e.g., https://example.com in the simulator and connect the web inspector, everything works fine. The web inspector also works fine in Safari on macOS (OUTSIDE the simulator) when accessing non-HTTPS sites. It's only a problem for non-HTTPS sites when connecting to the simulator. A coworker has the same problem, so it is not isolated to my machine. I would enable TLS locally as a workaround, but this web app is very complex, and I know from experience that it is very difficult for various reasons to set it up properly for our project in development, and it will take significant non-trivial work to do so. So... Why is this happening? Is this expected behavior? Is there a way that I can debug my site on localhost without HTTPS?

I am developing an SSO Extension so that I can have SSO with Keycloak across applications. OIDC/OAuth2 works very well. But I am struggling with SAML. It works, but it seems that the form submission is always triggered twice. I use decisionHandler(.cancel) to stop the form submission and redirect it to the browser. I still get the form submitted both by the extension and by the browser. At some point I tried to allow the form submission in the Extension so that I get the redirect with the response to the browser. It still triggered another submission. Does anyone experience this issue?

//Is my post method correct because google and claude are telling me I must use content type for the json and use .setvalue.
