We are seeing network errors in Outlook mail on iOS and MacOS safari browsers. As per current investigation, we notice these network error when the user tries to use outlook after leaving it open on Safari for a while. Observations: Issue present in both MacOS and iOS safari. Issue is not present in other webkit browsers like brave and edge on iOS. Issue is reproable on both mini and big owa on safari browser. Issue is not related to post requests being sent in different packets on safari browser. Requests are only blocked for outlook.office/outlook.live domains What does not fix this issue? Reloading the application Clearing cookie, local storage or session storage Unregistering service workers Redirecting to a different page and coming back to outlook domain Re authenticating the users What fixes this issue? Reconnecting to wifi or mobile network Reconnecting vpn Removing safari from background and reopening Flushing the dns in setting

I would like to know if there is a way to disable Smart Punctuation from the webpage rather than requiring the user to do so from the settings. Adding a "inputmode=verbatim" attribute to the input HTML tags for my webpage did that for all the web browsers I tested on Windows, Ubuntu, Android, and MacOS. I tested Chrome and Firefox on all platforms, as well as Edge on Windows and Safari on Mac and iOS. So far the only time it did not disable Smart Punctuation was on Safari on iOS, but it did on MacOS.

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.

When a DNR rule is set for a specific URL and the request receives a server-side redirect (e.g., 302) to a different URL that does not match the urlFilter, the rule still seems to apply to the redirected request. We are using macOS 15.4 and Safari 18.4. For example, consider two sequential calls: call1 and call2. call1 triggers a 302 redirect to call2. A DNR rule is created to add a "Cookie" header to call1 based on its URL. Unexpectedly, the same cookie is also added to call2, even though call2's URL does not match the rule's urlFilter. This results in the Set-Cookie response from call1 being ignored, and call2 receiving the manually set cookie instead—leading to incorrect behavior. This issue doesn't occur in Chrome or Firefox, where the rule is not applied to the redirected request if the URL no longer matches. We are looking for assistance in fixing these issues and having our Safari Extension function the same as it does in Firefox and Chrome.

We’re seeing an issue in our Safari Web Extension where not all cookies from the Set-Cookie response header are accessible. We are using macOS 15.4 and Safari 18.4. In the webRequest.onHeadersReceived callback, the Set-Cookie header returned by Safari only includes some of the cookies set by the server. If multiple Set-Cookie headers are present, we seem to receive only a partial list, some cookies are missing entirely. In Chrome and Firefox, the same callback provides all cookies set by the server without issue. We are looking for assistance in fixing these issues and having our Safari Extension function the same as it does in Firefox and Chrome.

Safari Extension Error: “Non-persistent background content cannot listen to webRequest events.” after macOS 15.4 / Safari 18.4 Update We’re seeing the following error in the Safari Extensions tab after updating to macOS 15.4 and Safari 18.4: “Non-persistent background content cannot listen to webRequest events.” This error did not appear prior to the update, and we haven’t found any official documentation stating that webRequest API is no longer supported in Safari. In our extension (Manifest V3), we are using the webRequest.onHeadersReceived callback to intercept response headers and read updated cookies. While the functionality itself still works as expected. we’re able to access the response headers and this error is now shown in the Extension settings page. We are not seeing this issue in other browsers (Chrome, Firefox) using the same Manifest V3 setup. Is there any plan to deprecate webRequest support in Manifest V3 for Safari? We’d appreciate any clarification or guidance on how to handle this going forward.

I’ve been working on a personal iOS project for fun — essentially a YouTube music player, learning how background media playback works in native iOS apps. After seeing that Musi (a famous music streaming app) can play YouTube audio in the background with the screen off — I got really curious. I’ve been trying to replicate that basic background audio functionality for YouTube embeds using WKWebView. I've spent a crazy amount of time (probably 20 hours) trying to figure this out but have achieved no success. Here’s what I’ve tried so far: -Embedding a YouTube video in a WKWebView -Activating AVAudioSession with .playback and setting .setActive(true) -Adding the UIBackgroundModes key with audio in Info.plist -Adding the NSAppTransportSecurity key to allow arbitrary loads --Testing on a real device (iPhone 14, iOS 18.1 target)-- What happens: Audio plays fine in the foreground. If I exit the app and go to the lock screen quickly enough (less than 3 seconds) after pressing play, I can resume playback briefly from the lock screen — but it doesn’t automatically continue like in Musi and other apps like it. Most of the time, the audio stops when the app is backgrounded. I get this error consistently in the logs: Error acquiring assertion: <Error Domain=RBSServiceErrorDomain Code=1 "(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)" It seems like the app lacks some specific entitlements related to WebKit media playback. I don’t have AppDelegate/SceneDelegate (using SwiftUI), but can add if needed. I’m super curious how music streaming apps using youtube as a source get around this — are they doing something different under the hood? A custom player? A SafariViewController trick? Is there a specific way to configure WKWebView to keep playing in the background, or is this a known limitation? Would really appreciate any insight from folks who’ve explored this before or know how apps like Musi pulled it off. Thanks in advance!

I am running Appium tests on an iOS 18 simulator, and I am encountering an intermittent issue where the device screen gets locked unexpectedly during the tests. The Appium logs show no errors or unusual activity, and all commands appear to be executed successfully. However, upon reviewing the device logs, I see entries related to the lock event, but the exact cause remains unclear. SpringBoard: (SpringBoard) [com.apple.SpringBoard:Common] lockUIFromSource:Boot options:{ SBUILockOptionsLockAutomaticallyKey: 1, SBUILockOptionsForceLockKey: 1, SBUILockOptionsUseScreenOffModeKey: 0 } SpringBoard: (SpringBoard) [com.apple.SpringBoard:Common] -[SBTelephonyManager inCall] 0 SpringBoard: (SpringBoard) [com.apple.SpringBoard:Common] LockUI from source: Now locking Has anyone experienced similar behavior with Appium on iOS 18, or could there be a setting or configuration in the simulator that is causing this issue?

We are encountering a download issue in Safari 18.2 on macOS Sequoia 15.2 where file downloads initiated by our AngularJS application (such as Excel exports) are silently blocked. There are no errors in the browser console, and the download does not occur. Interestingly, after testing on Safari 18.3 with Sequoia 15.3, the downloads worked as expected. However, the problem reappeared on Safari 18.4 with Sequoia 15.4. We suspect that recent changes in Safari’s security or download handling may be preventing downloads triggered via asynchronous JavaScript (e.g., AJAX calls) that are not initiated directly by user interaction. We would appreciate any insights, suggestions, or possible workarounds from the community. Looking forward to your guidance on this matter.

Since the transition to iOS 18.4, we have been having an issue where when loading an m3u8 file specified in the src attribute of a video tag in WKWebView, the ts file is loaded repeatedly. Are there any good ideas for this? Also, if there have been any changes to the specifications of WKWebView, we would appreciate it if you could let us know.

Hello, I'm trying to create a webbrowser but currently when signed into apple music webplayer I get the following message when I attempt to play on any versions of my webbrowser: Not available on the web You can listen to this in the Apple Music app. Is there a way to setup DRM (assuming this is the issue) with apple to allow my webbrowser to play this content? I believe Apple TV is also affected. Thank you ahead of time.

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!

Hello! I have a few questions about integrating an OAuth2 API into my Swift application. I am using this API to access user data from the website (users will authenticate themselves within the app). I have seen other apps use this API in the way that I am describing it so I know that it is possible. However, I am not sure how to implement it. Are there any recommended ways to use an OAuth2 API in my application? The API that I am using does not specifically say that it supports PKCE. However, I have heard from some sources that it does. If it does not support PKCE, how do I still create a secure app infrastructure that will pass App Store Review? At a more basic level, what is the difference between OAuth2 and PKCE? What should I use in my app? Are there any resources to learn a little bit more about these protocols so that I understand them better? Thanks!

I'm not loving the huge Favorites icons in Safari on MacOS 26, is there a way to reduce the size of them so that we can see more favorites on the list without scrolling down?

Hello there, For a video like this <video src="blob:safari-web-extension://***" autoplay="" loop="" style="position: absolute; top: 0px; left: 0px; width: 100%; height: 100%; object-fit: cover; z-index: -1;"></video>, no matter if its local or remote, blob or mp4 files, is constantly being reloaded (refetched? revalidated?) if the loop tag is added. I can confirm there is actual constant traffic from the server based on my server logs. I am running iOS/macOS 26.

How can I make a background image take the entire screen in ios26? I've tried position fixed, sticky, env() css variables but nothing worked. It does it when in PWA mode, but I would like to do so in the browser too.

I'm trying to download mods for Stardew Valley, before the beta it worked but now it doesn't. Is there anyone who can help to fix this? Used Firefox and Safari as well as Safari on my ipad.

We are working on an internal enterprise iOS application which we need to host a pretty complex web page inside. We have been reading regarding the WKWebView and how it performs inside of iOS shell, but there is no real data on what are the limitation of the WKWebView in terms of memory for the hosted Web Page. Let's say we could measure our iOS app before the WKWebView is launched and after it is launched. We see that the memory consumption of the web page loaded into WKWebView is X mb. How would we know that iOS would allow an app with such webpage loaded into WKWebView and won't terminate the app which the web page is loaded. Is there any documentation regarding on what is the maximum allowed memory for the web page which is hosted inside of WKWebView? And another question, for the Enterprise Developer Program are there any ways to increase the limit of the memory a specific iOS app is allowed to consume before it is terminated from iOS device due to low memory warning from iOS?

Hello, We received a rejection on one of our IOS applications because we were doing Microsoft MSAL login through the user's browser. The representative recommended that we use Webview to do in-app logins. However when we tried to handle the custom app uri redirection (looking like myapp://auth/), Webview does not seem to send the user back to the application. Does anyone have a fix for this? Thanks!

After reading several posts I see that I need to add the "com.apple.developer.web-browser.public-key-credential" capability to my macOS app in order to get it to work. So my noob question is where do I request this capability? Can I as a developer request it or does the Account owner need to request it? Once approved, how do I add it to my app's capabilities? Thanks for your patience
