Starting Safari 18, Declarative Net Request redirections are no longer working (it used to be working on Safari 17). It seems to be related to the regex validation that is not working as expected. Here is an example of our DNR rule: { priority: 1, action: { type: 'redirect', redirect: { regexSubstitution: `${scheme}//${extensionHost}/index.html\\1#/\\2`, }, }, condition: { // app.dashlane.com, *.app.dashlane.com regexFilter: '^https?://w*\\.?app\\.dashlane\\.com(\\??[^/#]*)[^#]*#?/?(.*)$', resourceTypes: [ 'main_frame' ], }, } Is it a known issue ? Also, it seems to be related to this existing issue: https://forums.developer.apple.com/forums/thread/763505

Safari samesite none cookie added after login but we are facing the issue in post method. While doing the post method cookie not getting into request header.And always sending the new cookie in the response header. Safari not sending the cookie into request header with samesite none. Kindly help me out.

The specification states that the timestamp property is a DOMHighResTimeStamp which always represents a value in milliseconds. However, in my testing (on iOS as I don't have a mac) the timestamp is given as seconds. This could break compatibility if an app/library is not tested in Safari. Worse is that the deviation seems to be undocumented as every compatibility chart states full compatibility and defines the property as milliseconds. Any workaround would also be up to one frame incorrect. So a stutter can affect input accuracy. I know this might seem small but it could mean that an app or game is unplayable in Safari if it relies on this for input.

When a video in Safari is played in fullscreen mode and the user pauses it, an overlay (such as a play button or other controls) appears. This affects the user experience, as we want to avoid showing the overlay during fullscreen viewing after the video is paused. Expected Behavior: The overlay should not appear after the video is paused in fullscreen mode. Steps to Reproduce: Open a webpage https://slides-dev.pitchavatar.com/rtxuf in Safari. Start playing the video. Enter fullscreen mode. Pause the video. The overlay appears after the video is paused. Screenshot: Additional Information: Safari version: Safari 18.0.1 (20619.1.26.31.7) Environment: macOS Sequoia 15.0.1 (24A348) We would like to know if there is there any way to prevent the overlay from appearing in Safari when the video is paused in fullscreen mode.

Hi Folks, do you know what happend with the "shape detection API" feature flag on Safari 18.X (IOs 18.X)?... in previous versions (17.X) i enabled the "shape detection API" feature flag and was able to detect codes like mentioned here... https://developer.mozilla.org/en-US/docs/Web/API/Barcode_Detection_API#browser_compatibility I built a PWA (Service Worker) with Angular 18 and facing this issue immediately after updating to IOS 18.0 (I enabled/disabled the flag, restartet the device several times... no success at all) Do you have an Idea what changed or how i can enable that feature again? Thx a lot in advance.. Cheers Martin

I was able to setup a release test for an iOS app for distribution using a web server. It works perfectly fine for all the devices I registered for the deployment profile. However every time I try to distribute a Unity based Vision Pro application using the same process for building the package and set up for distribution it does not work. Safari only shows a message telling me: "Cannot connect to ." When trying to install the iOS app from the same server it shows the message "Do you want to install ?" and installation completes correctly. My iOS is a simple hello world app generated by Xcode. My Unity app is an AR app targeting com.apple.platform.xros. According to documentation there should not be any difference in deployment profiles/signing for iOS apps vs. visionOS apps. What am I doing wrong? Any hint is appreciated how to continue.

Hello everyone, I’m working on adding a Safari extension as an application extension to an iOS app created using Capacitor (generated from a React app). My goal is to bundle the Safari extension within the Capacitor app, allowing it to serve as a companion app for the extension. However, I’ve run into issues where the extension does not show up in Safari's extension settings when I run the app on a device or simulator. Here's an overview of what I’ve done so far: I initially used Capacitor’s command line tools to generate the iOS app from my React project. This app runs fine on its own. To add the Safari extension, I’m not developing a platform-specific extension from scratch; instead, I used the Xcode command line to convert a Chrome extension to a Safari iOS extension. The converted extension functions correctly if paired with the default Swift app that comes with the conversion. Right now, I effectively have two products: The base Capacitor app (without the extension), which I want as my main app. The standalone Safari extension bundled with the Swift app (from the conversion process). My question is: How can I merge these two products so that the Capacitor app becomes the companion app for the Safari extension, allowing the extension to show up in Safari's settings? Are there specific configurations I should adjust in Xcode or within the manifest files to make this work seamlessly? Any guidance or best practices from others who have integrated Safari extensions into non-Xcode-based projects would be much appreciated! Thank you!

Hello! I have a question about changes in default behavior of Safari related to cookie setting. We had an issue - our Single Sign On login was not working, because of lost cookie on some step of the flow. Only changes in Safari cross-website tracking settings helped to fix the issue So the question is - are there any official documentation about changes in cookie setting policy in Safari on iOS 18?

On my M3 MacBook Pro 14'' laptop, when using Safari responsive design mode I cannot see any simulators when choosing "Open With Simulator". I am on the latest Sequoia 15.1 and Xcode version is 16.1. However when I successfully run a simulator from Xcode (Developer Tools -> Simulator) I can see the simulator running in the "Open With Simulator" dropdown but I cannot click it to run it with my safari desktop. I can never link my desktop safari app to a simulator. I feel I have read almost every how to blog but have no more options left to get this working. I've tried reinstalling Xcode and the iOS 18.1 environment on it, updating safari and anything else that might be out of date but still with no luck after much restarting programs and my machine. Is there another way to try and run a simulator from Safari?

I've observed a discrepancy in cookie consent options between iOS 18.0 and 18.1 on some websites, such as www2.hm.com. On iOS 18.0, I see "Accept All Cookies" and "Only Required Cookies" options, whereas on iOS 18.1, the options change to "Accept All Cookies" and "Cookie Settings." I would like to understand if this behavior is related to differences in how websites detect the operating system version (iOS 18.0 vs. 18.1) or browser changes within the iOS update. Has anyone else experienced similar variations in cookie consent banners, and could this be tied to differences in the user agent or website A/B testing for different OS versions? Any insights or technical clarifications would be appreciated!

Howdy! On Safari, when using the column-count CSS property to split text into multiple columns, I've noticed that when applying a text-shadow, there is an unexpected whitespace created above all subsequent columns. I've put together a codepen demonstrating the issue and its reproducibility on Safari (using latest as of this posting: Version 17.6 (19618.3.11.11.5)) Codepen: https://codepen.io/cubepresser/pen/ExqvzjL Expected behavior: Actual: I tested this on the latest versions of Chrome, Firefox and Edge. This bug does not occur. Expected behavior is that there should not be an extra line added to the beginning of the second column, third column, etc. Here's some code if that codepen link doesn't work: HTML: <p id="example">0000000000111111111122222222223333333333</p> CSS: #example { font-family: monospace; max-width: 20ch; column-count: 2; column-gap: 0; word-break: break-all; line-break: anywhere; text-shadow: 0 0 4px black; }

Hi all. So, I built the platform SSO extension on a demo server I created and everything ran smoothly. I get the tokens at the end of the process. Now, I want to use the tokens when I trigger my SSO extension in my domain from Safari. I trigger my domain, get into the beginAuthorization method, get the request.loginManager?.ssoTokens and then want to return them to Safari by calling the request.complete method. But, no matter what complete method I call (complete(httpResponse: HTTPURLResponse, httpBody: Data?) or complete(httpAuthorizationHeaders: [String : String]) where I insert the Bearer token into the Authorization header, it will not drill down to Safari or my server. The headers I try to send back are not moving from the extension to Safari. Some knows why its happening? Thank you for any help or suggestion.

I'm developing two native apps and one is a authentication app and other one is business app. In the main flow if buisness application is on the foreground and did nothing for at least 10 minutes it will automatically time out and redirect to the autentication app for token refresh. In this flow universal link redirect to the authetication app without opening Safari. But if i execute the below flow buissness app redirect to the Safari. Buisness App In Foregorund → Displaying a OS screen while app is in Foreground(Like Push Notification Center) → On this satate leave device for 10 minutes → Buisness app will automatically timeout and rediret to Safari(In safari 「NoSuchKey The specified key does not exist.」message is displaying but authentication app Universal link Start button is showing) → After click the Universal Link start button in Safari Authentication App open. I use the below code to start the Universal Link: if let url = URL(string: path) { UIApplication.shared.open(url) } So i would like to know is there a special reason that when Displaying a OS screen while app is in Foreground(Like Push Notification Center) affect the normal flow of Universal redirection to another app?

Hello, I can't figure out how to set the name of a Content Blocker in the Safari extensions list. So far, the Content Blocker name in this list is the Contaning application name. I tried to set the bundle name in Info.plist and tried to locate Info.plist, without success... Since I also bundle a Safari ("chrome") extension, I have two extensions in the list, and it would be fine to display a specific name for each to make it clear for the user.

I'm developing an application that utilizes WKWebView to display a webpage. My goal is to improve the performance and loading speed of this webpage by intercepting specific API calls and providing pre-stored JSON responses directly from within the app, ensuring the webpage renders instantaneously. The challenge I am encountering is the inability to intercept HTTPS URL schemes directly from WKWebView. Any insights or solutions from the community on how to effectively manage and overwrite these particular network requests would be greatly appreciated.

When user opens a new tab and loads a website, the declarativeNetRequest.getMatchedRules() returns nil and on reloading in the same tab it returns the URLs blocked. Is this an expected behaviour?

Hello. I’m trying to use Core Location Service on any application in Mac (Safari, Maps, Weather, Chrome with Core Location configuration, or just trigger the API with a standalone app) and it seems that all of them constantly fail to provide the geolocation of my device because of the same error (kCLErrorLocationUnknown). I'm using MacBook Pro (M3 Max) with Sonoma 14.7. I’m sure the apps have access in the settings and everything is in order except the Core Location response. I’ve tested the issue on multiple MacBooks and it reproduced 100% of the times on all of them. Did anyone encounter a similar issue?

Hi, I’m seeking information about the HLS protocol version supported in Safari on macOS. The official documentation only provides details about iOS support. Is there an official document that addresses this? Best regards

Hi. I've noticed on both iOS 17 and iPadOS 16 that when an user opens a website in a WKWebview (e.g from Gmail), then requests it to be opened in the external Safari app (through the "compass" icon), their localStorage data is not transferred to the Safari tab. This behaviour breaks web experiences that rely on data being locally stored, e.g auth tokens or user identification data. It effectively stops users from being able to use some websites outside of an in-app context. I am aware of Webkit's tracking prevention mechanisms such as https://webkit.org/tracking-prevention/#partitioned-third-party-localstorage, but I don't think this should apply to this case. Here the user is navigating between two Safari tabs (one internal and one external) on the same domain, exact same URL, by pressing a native Safari webview icon. There is no third-party cross-domain tracking happening. Is this a bug or intended behaviour?

I have noticed that tabs.onRemoved works differently in Safari 18 comparing to other browsers and Safari 17. Open a tab e.g. apple.com Take note of the active tab id using this code: browser.tabs.query({currentWindow: true, active: true}, (x) => console.log(x[0].id)) Add a listener on onRemoved: browser.tabs.onRemoved.addListener(console.log) on the active tab, navigate to e.g. https://developer.mozilla.org Take note of the active tab id again (using the same tabs.query). Expect: there should be no console.log of onRemoved. the active tab id stays the same. Actual: there is a console.log of onRemoved. the active tab id is changed. Please help. If this is a bug introduced in Safari 18, it would break a lot of JS Web extensions.
