Hi! I'm working on a web extension for Safari and I need to send messages from the containing application to JavaScript. For this I use the method class func dispatchMessage( withName messageName: String, toExtensionWithIdentifier identifier: String, userInfo: [String : Any]? = nil ) async throws of the SFSafariApplication class. If the site is opened in Safari in normal mode, everything works as expected. However, if the site is "docked", the messages are not transmitted to this "Web App". Is it possible to somehow link the container application to the docked website so that messages from the application are received by this "Web App"? That you.

When we embed some of the youtube videos are unable to load in the Mobile app but at the same time it works in Website. I need to allow it in both places. I have tried both embed and native sdk for youtube in iOS.

We confirmed a problem at Safari on iPadOS 18.2 or after version. For confirmation, we made a HTML document (see below HTML1) what include ‘method="POST" target="_blank"’ and tested the form however server received GET method and there is no parameter, server did not receive “id” parameter. We confirmed that fact in captured packet and log file that on the server. HTML1: We also made another HTML document (see below HTML2) what include submit button, but the server received GET method as above. HTML2: And we also confirmed that it behaves differently depending on the network environment. If the form targets a name that does not exist (ex. target=” A12345”), behaves differently http or https. http: Safari opened new tag, but the server received GET method. Normally, Safari open new tag and the server receive POST method. https: Safari opened new tag, and the server received POST method. It is normally. If the form targets ‘_blank’, the server received GET method on http or https both. We think Safari change the method POST to GET and delete parameters. It is not conformed to the HTML specification if is that true. We confirmed it was not happened at Safari on iPadOS 17.4, and Windows PC (Edge, Chrome). The method what the server received is POST. We find same problem in Apple Support Community (see below URL). https://discussionsjapan.apple.com/thread/255987615 (Described in Japanese) Is it a bug in Safari on iPadOS 18.2 or after version? Do you have plan to fix? Or if fixed the bug, when do you release fixed version.

The order nor -webkit-order properties of a child element of a flex parent dosen't work in Safari 18.3. Works correctly in FireFox and Chrome.

I have a business scenario where I want to guide users to Safari and open a Safari extension. How can I open Safari from my app and navigate to a specific webpage?

Hi Apple Devs & WebKit Team, We operate https://excnum.com — a personal website currently under reconstruction. It's HTTPS-secure, hosted on a clean VPS, and now features a simple placeholder page with no active forms, scripts, or external redirects. However, Safari on both iOS and macOS is flagging it as a “deceptive website”, blocking all access. This warning appears even though: The site uses a valid SSL certificate via Cloudflare There are no redirects, tracking scripts, or dynamic code We serve a static landing page (“under maintenance”) with zero interaction No malware, phishing, or obfuscation exists — verified with multiple tools A review request has already been submitted at: https://websitereview.apple.com We believe the site may have been blacklisted previously under past ownership or prior configurations. It has since been completely restructured and cleared, but the Safari warning persists. This false flag is harming visibility and trust for an otherwise neutral website. Any advice on how to expedite re-evaluation or request a manual delisting from the deceptive site list would be much appreciated. Thank you! — Alex Admin, EXCNUM.COM

If "Not Secure Connection Warnings" is enabled in the Settings > App > Safari, are no HTTP connections allowed? Setting NSAppTransportSecurity does not seem to apply either.

I am using SFSafariViewController to process payments via a Stripe checkout URL. Once the payment is completed, the user is redirected to a success URL. I have also added associated domains for deep linking. Below is my implementation: func presentCheckout(url: String) { showProgressHUD() let checkoutURL = URL(string: url)! safariVC = SFSafariViewController(url: checkoutURL) safariVC.delegate = self self.present(safariVC, animated: true) } // Delegate method implementations func safariViewControllerDidFinish(_ controller: SFSafariViewController) { print("SafariViewController dismissed") // Handle dismissal } func safariViewController(_ controller: SFSafariViewController, initialLoadDidRedirectTo URL: URL) { print(URL.absoluteString) if URL.absoluteString.contains("xsworld/payment/stripe/checkout/success") { controller.dismiss(animated: true) { if URL.absoluteString.contains("/v1/resources/xsworld/payment/stripe/checkout") { NotificationCenter.default.post( name: Notification.Name("StripePaymentStatus"), object: nil, userInfo: ["url": URL] ) } } } else if URL.absoluteString.contains("xsworld/payment/stripe/checkout/cancel") { // Handle failure NotificationCenter.default.post( name: Notification.Name("StripePaymentStatus"), object: nil, userInfo: ["url": URL] ) } } func safariViewController(_ controller: SFSafariViewController, didCompleteInitialLoad didLoadSuccessfully: Bool) { if didLoadSuccessfully { print("Initial page loaded successfully") } else { print("Initial page load failed") } } Issue: The safariViewController(_:initialLoadDidRedirectTo:) method does not always get called after the payment is completed. Sometimes it works as expected, and sometimes it does not trigger at all. What I’ve Tried: Ensuring the associated domains for deep linking are correctly set up. Checking the success and failure URLs. Debugging to see if the redirect happens but is not detected. What I Need Help With: I want to ensure that the redirection always works after the payment process is completed, whether through deep linking or another reliable approach. How can I guarantee that my app correctly detects and handles the redirect every time? Any guidance or best practices would be greatly appreciated.

When the iCloud Passwords Chrome extension is on, there is a 400-500ms lag between clicking on a non-password field and the UI reflecting any changes made by a .on("focus") jQuery listener. When the extension is disabled, there is no lag. See below the performance profiles for the same 4 click events. Extension ON: Extension OFF:

iOS 26 (from beta 1 to beta 2) We have a VPN app that installs a per-app VPN profile with SafariDomains to filter Safari network traffic. This setup works as expected on iOS versions lower than 26.0. See here more details on SafariDomains: https://developer.apple.com/business/documentation/Configuration-Profile-Reference.pdf On iOS 26, all SafariDomains configured to go through the per-app VPN result in the following error: "Safari can’t open the page. The error was: Unknown Error" Additional Details: Only SafariDomains encounter this error. Other managed apps traffic through the per-app VPN works correctly. Steps to Reproduce: Install the VPN app with a per-app VPN profile. Configure SafariDomains with any URL (e.g., example.com). Open Safari and navigate to the configured URL. Example Configuration: We tested with a simple example by adding only one URL to SafariDomains (example.com). Logs from the console were captured at the moment Safari opened and encountered the error. safari_google2.txt Has anyone else encountered this issue on iOS 26? Any insights or solutions would be greatly appreciated. Thank you!

I have a local HTML file used to display mixed content with images and text. Here's the issue: the same file displays everything correctly in Google Chrome, showing both images and text as expected. However, when opened in Safari, only the text is shown—images are missing, which is very strange. Interestingly, if I remove .png from the title attribute of the tag, the images show up properly in Safari. Alternatively, if I comment out the inclusion of html2canvas.min.js, the images also display correctly (although the layout breaks without it). I'm not sure if this is a Safari-specific issue. Can anyone explain what might be causing this problem?

We have a Web Extension that uses firebase for auth. It was working fine until the latest version of Safari 18.3 got released few days ago on January 27, 2025. All of out extension versions stopped working on it; even the ones that are published on App Store. It uses FirebaseJS v9.23.0. Same version of the extension are working fine on other browsers. We use onAuthStateChanged to listen to auth related events; but it is never fired now.

My website ccflood.us is a simple map that uses a CSV file for the data that is displayed on the map. It uses the ESRI JS API. Recently the points on the map began missing the text in the boxes only on Apple devices that have been upgraded to iOS 18. Has anyone also had this happen to their site? If you have upgraded to iOS 18, try this site on your iPhone then look at it on an Android phone or your desktop browser. You should seet the values in the boxes and a "+" at points that have no value. If you've had this happen with your site or have heard of a fix, please reply to this post.

The extension popups don't seem to support the dark mode media query. The only way the query gets detected is when a color-scheme is added: <meta name="color-scheme"content="light dark">

I build websites and my current build has seven videos on the first page built with the html 'video' tag. The page renders on all browsers and Android and on Safari on my mac but on my iPhone safari they appear black and then play correctly when clicked. This has changed since the last update.

I have a UI application built with the Vue framework, using Vuetify for the UI components. There's a div with the class v-application--wrap, which is provided by Vuetify. This class internally includes the following style rule. .v-application--wrap { backface-visibility: hidden; display: flex; flex: 1 1 auto; flex-direction: column; max-width: 100%; min-height: 100vh; position: relative; } The pages were rendering correctly up to version 18.3, but after upgrading to version 18.4, we encountered layout issues related to height. Upon investigation, we discovered that the min-height property was no longer being interpreted or applied correctly. Replacing min-height with height resolved the issue, and the pages began loading as expected. Any insights into why this behavior is occurring would be greatly appreciated.

ios drop file wrong file name I use the following simple JS code to drag file from the browser to the desktop. Works perfect on MacOS. onDragStart(event, ucpView) { let file = new BrowserFile([this.file.fileContent], this.file.displayName, { type: 'application/ucp-scenario' }); const fileURL = URL.createObjectURL(file); event.dataTransfer.setData("DownloadURL", `application/octet-stream:${file.name}:${fileURL}`); event.dataTransfer.setData("text/uri-list", fileURL); } but on iOS it keeps nameing the file Text1.txt Text2.txt ... and ignores the DownloadURL whats the best way to get it workng on both OS?

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 to the server which will be used for verification. How can i do that?

Hello Apple Developer Team, I would love to see iCloud Keychain Autofill and Touch ID support extended to Chromium-based browsers on macOS (such as Ecosia, Brave, or Vivaldi). Currently, Safari allows autofill of passwords using Touch ID, but when using other browsers, I have to manually copy-paste credentials from Keychain Access, which is time-consuming. Would it be possible for Apple to provide an API or framework that allows non-WebKit browsers to integrate iCloud Keychain autofill while keeping security intact? This feature would make macOS more convenient for users who prefer alternative browsers while keeping security standards high. Thanks in advance for considering this! Best regards, Kilian

Hello, We are developing a Safari Web Extension that uses a cookie-based authentication mechanism. The extension makes a request to an endpoint e.g. /login, and this endpoint expects a cookie (e.g., sessionId) to be included with the request. Everything works correctly when running in the default Safari profile. However, when I install and run the same extension in a new, non-default profile, the behaviour changes: The request to /login is still made The cookie sent is not as expected As a result, the response returns null user data I confirmed that logging into the site in the new profile (in a tab) works, but the extension does not appear to share the session/cookie state with the login tab We’ve tried explicitly setting "credentials": "include" in the request but that still didn’t share the cookie in the extension context in the non-default profile. My questions: Is there away to allow cookie-based session sharing between a tab and an extension in non-default profiles in safari? Would switching to a token-based auth mechanism (e.g., Bearer tokens ) be the recommended workaround? I’d appreciate any insights or guidance from those who’ve run into similar issues. 
 Thanks in advance!
