We are testing our safari web extension (https://apps.apple.com/us/app/whatfix-for-jnj-centris/id6723895659) on an iPad 7th Gen (iPadOS v - 17.4.1) I am sharing a video link where you can see the widget (named Self Help) appears on the application. However after a couple of refreshes, it vanishes. This widget is powered by the extension. We tried connecting the iPad to Mac and opened the webinspector. The extension content script sends a message to the service worker and it is expected to send back a response which it is not doing We believe it is related to an issue that has been highlighted multiple times in the developer forum - https://developer.apple.com/forums/thread/758346 We have tried using several workaorunds as suggested by peer developers in the thread but we are unable to revive the service worker once it is killed. We would like to understand from you, how to recover from this issue. Is there any workaround that we can apply to make sure that extension works fine? It would be immensely helpful if we can get on a call to explain the issue further Video Link: https://www.icloud.com/iclouddrive/0a7NR7BzDQHHU8zCHERuySBMw#RPReplay%5FFinal1740034010

I am trying to cache fonts natively in a hybrid app, so that CSS hosted in an https website loaded in WKWebView through loadRequest can reference them like this for a performance boost: @font-face { font-family: 'MyFont'; src: url('my-assets://Gordita-bold-subset.woff') format('woff'); font-weight: normal; font-style: normal; } The problem happens when I register a WKURLSchemeHandler for my-assets. The handler never gets called and the Safari Web Insepctor shows this: [blocked] The page at https://www.x.com/ requested insecure content from my-assets://Gordita-bold-subset.woff. This content was blocked and must be served over HTTPS. Interestingly enough, if we try to serve content with <img src="my-assets://test.png" this restriction does not apply. Are there any workarounds other than using the private API WKProcessPool._registerURLSchemeAsSecure?

Hi guys, I'm trying to use sign in with apple in javascript, I followed the guider in the website, and almost find everything I can find in Google, but nothing help, here is my situation: I create a new App: com.yuhan.test.app I create a new service ID: com.yuhan.test.service configure a domain and return url domain: tts.perterpon.com returnURL: https://tts.perterpon.com/login create a new key for Sign In with Apple. my html code is here, it's easy, but it always told me invalid_client, I think I have done anything I need to do, can somebody help me? Thank you so much. you can test my online web site: https://tts.perterpon.com/login.html ` const buttonElementNew = document.getElementById('appleid-signin'); buttonElementNew.addEventListener('click', async () => { try { const data = await AppleID.auth.signIn() console.log('Try/Catch Data', data.authorization.id_token); const formData = new FormData(); formData.append("token", data.authorization.id_token); await fetch("", { method: "POST", body: formData, }); // Handle successful response. } catch (error) { // Handle error. } }); </script>

Hi, I have tried to research how safari clean up the cookie when it reaches maximum limit (4kb) on internet but cannot find a good answer. Anyone can help me to give an answer for this question? Thanks in advance

In a project to create a web extension for Safari, using scripting.registerContentScript() API to inject a bunch of scripts into web pages, I needed to manage a dynamic whitelist (i.e., web pages where the scripts should not be injected). Fortunately, scripting.registerContentScripts() gives you the option of defining a list of web pages to be considered as a whitelist, using the excludeMatches parameter in the directive, to represent an array of pages where the script should not be injected. Here just a sample of what I mean: const matches = ['*://*/*']; const excludeMatches = ['*://*.example.com/*']; const directive = { id: 'injected-jstest', js: ['injectedscript.js'], matches: matches, excludeMatches: excludeMatches, persistAcrossSessions: false, runAt: 'document_start' }; await browser.scripting.registerContentScripts([directive]) .catch(reason => { console.log("[SW] >>> inject script error:",reason); }); Of course, the whitelist (the excludeMatches array) is not static, but varies over time according to the needs of the moment. Everything works perfectly in Chromium browsers (Chrome, Edge, ...) and Firefox, but fails miserably in Safari. In fact, Safari seems to completely ignore the excludeMatches parameter and injects the script even where it should not. Has anyone had the same problem and solved it somehow? NOTE : To test the correctness and capabilities of the API in each browser, I created a simple repository on Github with the extension code for Chromium, Firefox and Safari (XCode project).

In a Safari Web Extension using Manifest V3, how can a content script access an HTML file that is bundled with the extension (e.g., to inject it as an iframe)? Safari's CSP seem to prevent the use of browser.runtime.getURL() in the MAIN world — is there a recommended way to load such resources securely?

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: 🔗 CodePen Demo 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!

Apple must comply with the requirements of the Level Index, the global digital credit gateway, and suspend gift cards and similar services until formal arrangements are made with service providers.

Hey there. I recently completed an Apple Pay (on the web) integration and it has been working fine, for the most part. I had one customer contact us saying that it didn't work on his devices though. I checked it out, and while it does normally work (and we've had over a thousand transactions use it) there does seem to be some scenarios where it fails and I'm not sure why. I was able to replicate his issue (or at least an issue) by using BrowserStack. When I click the button which should initiate the payment, everything works in the JS code until it gets to the applePaySession.begin() function call. Once it hits that, it just stops. No errors are generated and no notice is given that anything is wrong until you try to do it a second time. Then an error about a payment session already being active on the page is thrown. I'm not really sure how to troubleshoot this since I know it works on my old iPad Air 2, my current M4 Macbook, multiple other devices, and also works when scanning the QR code for use on an iPhone. There is some very specific thing with some very specific versions of Safari that seem to be tripping it up. If it helps, the version of Safari on the BrowserStack device is 18.1, but the version on my Macbook is 18.1.1. The version the customer who is having the issue is on is 18.2 according to him. The customer also says they have used ApplePay on other websites with no issues. I checked one of them and they appear to be using a PayPal integration, where as I am using the ApplePay SDK straight from Apple. There are quite a few variables at play here, and I'm just trying to narrow down what I should be looking at. If one person is reporting the issue, there are probably others with it as well.

Animated AVIFs don't work properly on Safari, with inconsistent behavior across iPhone models. On iPhone 14 Pro (A16, iOS 18.3.1), playback works fine, but on iPhone 15 (A16, iOS 18.3.1), it shows as a still image. iPhone 16 Pro (A18, iOS 18.4 beta) plays correctly, and M1 Pro MacBook handles it well too. Oddly, Xcode simulator (M1 Pro) only plays a specific file on iPhone 14 Pro. Is this tied to AV1 decoding differences (hardware vs. software) or a WebKit rendering issue? Any insights or documentation would help! Note: The tested images are commercial files, so I can’t attach them here, but I’m happy to share those upon request.

Hi everyone, We're facing a challenge with Apple's WKWebView and its WKAppBoundDomains limit. Our web app is hosted across multiple dedicated domains to ensure security and isolation for our customers. Additionally, we rely on a service worker to provide offline functionality within our app. To enable the service worker in our WebView app, we must specify the domains within the app-bound domains list. The issue we're encountering is the 10-domain limit, which is restrictive since our app needs to support access to more than 10 domains. Has anyone found a workaround for this limitation? Or does Apple provide any exceptions to this rule if a strong case is presented? We’d greatly appreciate any insights or experiences you can share. Thanks in advance!

My app sends users notifications of important messages in the app. How can I make sure the user receives them?

We are Java application developers and we have a question regarding camera access via WebRTC on iPadOS. Specifically, on iPadOS 17.1, we are encountering an issue when trying to access the camera via the WKWebView API in the Chrome browser, where an error occurs and the camera capture fails. Our investigation suggests that device access through the navigator.mediaDevices property via the WKWebView API may not work in Chrome. However, it works as expected in the Safari browser, leading us to wonder if this is a Chrome-specific limitation, or if it's due to an iPadOS setting or specification. At this point, we are unsure if this issue is related to the WKWebView and WebRTC specifications on iPadOS 17.1, or if there are specific limitations in Chrome. We would appreciate any insights or solutions regarding camera access in iPadOS 17.1 with WKWebView and WebRTC, especially in relation to Chrome.

Hello, following problems described here: https://developer.apple.com/forums/thread/765272 Last version of Safari apparently corrected previous bugs, however we encountered another problem. Right now Safari uses autocomplete feature of some kind (Siri suggested websites/Top hit) which triggers blocking while writing the name of the website. Probably somehow loads website in the background. Problem is, that this behavior is impossible to debug, because this autocomplete doesn't work, while the browser console is open. We are using content script for blocking. Please advise. Thanks very much

Subject: Help Needed with App Clip Implementation Hi Team, I need some assistance with implementing App Clip behavior in safari and also experimenting using TestFlight app. Default App Clip URL: https://appclip.apple.com/id?p=com.jey.ppclient-prod.appclip Website for App Clip Integration: https://appclip-sand.vercel.app/customer Current Behavior: Default App Clip URL: When I embed the default App Clip URL in an HTML tag like below: Launch App Clip it does launch the App Clip. but it says the appclip not supported in your region I've already added this configuration under Local Experience in App Store Connect. Website Integration: I’ve registered the site using the Advanced App Clip Experience. The apple-app-site-association file is in place. When I visit the site, the App Clip does launch as expected. What I Need Help With: I want to launch the App Clip from a custom button click, using either: The default App Clip URL, or The website URL (e.g., https://appclip-sand.vercel.app/customer) with additional query parameters like userId or sessionId. Is there a supported way to achieve this—perhaps through JavaScript or a specific tag setup that works with either Local or Advanced Experience? Your guidance would be greatly appreciated. Thanks, Jey

Hello. In Safari there are no eorking nee skins or walpapers!

Hi Team, We are trying to upload a file or an image using the component WKWebView. How we can do it? Should we need to use another approach? Do you have any suggestion or any demo project? Thanks in advance!

I have an app which has at least two extensions: A Content Blocker extension with a request handler that returns an appropriate NSExtensionItem as part of beginRequest. A different file URL is returned depending upon if the content blocking is on or off by a user setting A Safari Web Extension that includes a toolbar button and popover that enables users to enable or disable the ad blocking of the content blocker extension All three targets (App, Content Blocker appex and Web Extension appex) use an App Group default to read and set the on or off status of the content blocking. When the user changes the content blocking status, the app group default is updated and SFContentBlockerManager.reloadContentBlocker(...) is called. The Content Blocker extension reads the default and then returns the appropriate file URL. The issue is, I have noticed that whenever SFContentBlockerManager.reloadContentBlocker(...) is called from the app, Safari always applies the correct rules from the returned file URL. However sometimes when SFContentBlockerManager.reloadContentBlocker(...) is called from the Safari Web Extension using native messaging, Safari does NOT apply the correct rules from the returned file URL. Using logging I have confirmed that the Content Blocker extension always returns the appropriate file URL irrespective if called as a result of the app or the web extension. Despite this, Safari does not seem to always apply the returned file URL rules when it is called from the Safari Web Extension appex. In these cases, quitting Safari and relaunching it seems to make it apply the rules correctly (obviously this is applying it due to its launch state, not due to the Web extension appex asking it to do so at that point). All targets have access to the App Group location where the active content blocking file URL belongs and the inactive content blocking file URL is within the Safari content blocker target as a resource. I don't think this is a memory status issue as I cannot see the Content Blocker extension being killed when it returns complex rules --- the fact it always works when called via the app also seems to rule this possibility out. This brings up a number of questions: Is calling SFContentBlockerManager.reloadContentBlocker(...) from a different appex, of the same app target and app group supported? (it seems to work sometimes and did work in previous versions of the app). Is there an issue that the Content Blocker extension sometimes returns a file URL that perhaps the calling Web Extension appex may not have access to (even though Safari should via the Content Blocker extension)? Any other ideas of why this may not be working correctly? Has anyone else experienced this? It seems to happen on both iOS and macOS Safari using the same codebase.
