Actually this is a duplicate for https://developer.apple.com/forums/thread/106537 but in web-specific forums section.
Is there any video/audio codec best practices, guides, recommendations for app/web developers for best performance (take advantage from HW acceleration), power consumption saving? What are officially supported media containers? What are video encoding profiles, video dimensions, frame rates?
The only official source I have found is https://developer.apple.com/documentation/webkit/delivering-video-content-for-safari?language=objc. But h264 is pretty old. I experimentally found that the VP9 video format is also supported on iOS newer versions. But is this a requirement? Сan i be sure that the video will play on all devices?
My goal is to provide web media content (which will be rendered in my application using WKWebView API) that will be supported by most devices (both iOS and MacOS), takes advantage of such features as hardware decode acceleration and be efficient.
Any hints/info is highly appreciated. Best regards.

A DNR rule with lower priority is being applied before a DNR rule of higher priority on Safari. Specifically, a low-priority DNR block rule that matches a request is being applied before a high-priority DNR redirect rule that matches the same request, preventing the redirect from occurring. The only way to get the high-priority redirect rule to occur is to remove the DNR block rule. This does not occur on other browsers.
I have already submitted a Feedback Assistant report about this bug: FB16535579
How to reproduce:
Create/install a web extension on Safari with the declarativeNetRequest and declarativeNetRequestWithHostAccess permissions
Open the Web Extension Background Content console and add a redirect rule with a high priority number. For example:
await chrome.declarativeNetRequest.updateDynamicRules({addRules: [
{id: 5000, condition: {urlFilter: "||www.google-analytics.com*/ga.js", resourceTypes: ["script"], domainType: "thirdParty"}, priority: 80, action: {type: "redirect", redirect: {url: “http://www.apple.com/”}}}
]})
Add a block rule of lower priority for the same urlFilter:
await chrome.declarativeNetRequest.updateDynamicRules({addRules: [
{id: 5001, condition: {urlFilter: "||www.google-analytics.com^", domainType: "thirdParty"}, priority: 1, action: {type: "block"}}
]})
Visit https://efforg.github.io/privacybadger-test-fixtures/html/ga_surrogate.html
Check the network tab and see that neither a request to Google Analytics nor apple.com appear. This means that the request to Google Analytics was blocked instead of being / before being redirected
Remove the block rule:
await chrome.declarativeNetRequest.updateDynamicRules({removeRuleIds: [5001]})
Reload https://efforg.github.io/privacybadger-test-fixtures/html/ga_surrogate.html.
Check the network tab and confirm that there is a request to apple.com, showing that the redirect rule is only applied if the lower-priority block rule is removed. The priority of the DNR rules should handle this without having to remove a DNR rule.
I have confirmed that the incorrect application of DNR rule priority happens on other top level domains, with other urlFilters, and with other redirect URLs. I confirmed that this is happening while I’ve granted my extension permissions on all websites.

Safari Web Extension for enterprice distribution:
If I press run button on xcode it shows the safari web extension toggle and works perfect
When installed through exported ipa, the web extension toggle dissapears, it doesnt matter how it was installed through mdm, link, or directly ipa from xcode
I just exported an ipa as debugging and it worked when I pushed the ipa
We are experiencing a problem that seems to be caused by a specification changes for Safari.
We would like to discuss how to solve this problem.
Sample JavaScript:
<html>
<head>
<script>
function jumpPage(code) {
document.main.code.value = code;
win1=window.open("","win1","toolbar=no,resizable=yes,menubar=no,scrollbars=yes,status=yes,left=0,top=0");
win1.resizeTo(width=screen.availWidth,height=screen.availHeight);
document.main.action="details";
document.main.target="win1";
document.main.submit();
}
</script>
</head>
<body>
<form name="main" method="post" action="" target="">
<a href="javascript:jumpPage('001')">details</a>
<input type="hidden" name="code" value="">
</body>
</html>
This JavaScript performs the following actions when a link is clicked.
Open a window using window.open in JavaScript
Submit the above opened window by post method to the target in JavaScript.
When this operation is performed, the process in (2) could submit to the
target page with “POST” method before iOS18.1, but
will transition to the page with“GET”method from iOS18.2 onward.
All protocols are http.
This problem does not occur if the URL is specified as an IP address, but it does occur if the host name is specified as.
Please let me know how to use with“POST”method as in iOS 18.2 or earlier.
Best regards,

Hi Team,
I'm using the simple mailto functionality in the demo page and when I tested the same via Safari mailto functionality is not working.
However, the same feature is working as expected via Chrome.
Demo: https://jsfiddle.net/xut0ed4y/
Kindly help.me to resolve this issue.
I am a newby to JavaScript, suggested to me to use to automate the task of opening of a Web page, selecting three internal buttons in sequence to download the underlying chart data.
I have created the App via Automator on macOS, to run the Script, successfully open the Web Page, but cannot find a way to select and click() on the buttons.
Can someone please help me.
Robert.

I am encountering an issue where we are unable to run or launch Safari Driver in our automation tests using macOS. When attempting to run safaridriver -p 8888 from the terminal, we receive the following error message:
ERROR: safaridriver could not launch because it is not configured correctly or you need to authenticate. Re-run safaridriver(1) and pass the '--enable' flag to configure and/or authenticate.
For more information, consult the safaridriver(1) man page.
Despite running sudo safaridriver --enable as an administrator (even as root), the issue persists.
I’ve searched through various online forums and GitHub repositories but couldn’t find a working solution. Some references are:

Dear Apple Developer Support Team,
I am writing regarding critical issues we are facing with Safari web push notifications in our application iLiveMyLife.io, which is severely impacting our ability to maintain reliable communication with our users.
Issue Description:
We are experiencing persistent problems with Safari push notification tokens expiring or becoming invalid without any notification to our server. This creates several critical issues:
Users stop receiving notifications without any indication of failure
Our notification delivery system has no way to detect token expiration
The expiration appears to happen frequently (seemingly almost daily in some cases)
There is no reliable mechanism to re-establish push communication without users manually revisiting the app
Technical Impact:
Our messaging functionality becomes completely unreliable
We must resort to email or SMS as fallback mechanisms, which is not feasible for a real-time communication platform
This makes building any reliable messaging application on Safari practically impossible
The Broader Context:
What makes this situation particularly challenging is that all potential alternative browser APIs that could help address this issue appear to be deliberately disabled or restricted in Safari:
Background Service Workers don't function in the background on iOS Safari
Background Sync API is not supported
WebSockets cannot operate when the app is closed
There's no way to programmatically check the validity of push tokens
The combination of these limitations creates a situation where developers have no viable technical path to build reliable notification systems for PWAs on Safari. This appears to be a systematic restriction rather than individual API limitations.
Requested Information:
Is there a recommended approach to detect Safari push token expiration?
Are there alternative notification mechanisms for PWA applications on Safari that offer more reliability?
Is there documentation on the lifecycle of Safari push tokens that could help us implement proper handling?
Are there plans to improve the Web Push API implementation in Safari to address these reliability issues?
Could you clarify if these limitations are intentional design decisions or technical constraints that might be addressed in future updates?
Business Impact:
This issue fundamentally undermines our platform's core functionality. For a collaborative tool, reliable notifications are essential - users cannot collaborate effectively if they miss updates because their push tokens silently expired. The current state creates confusion among our users, who don't understand why they suddenly stop receiving notifications.
Any guidance or assistance you could provide would be greatly appreciated. We're committed to providing an excellent experience on Safari, but the current push notification limitations make this extremely challenging.
Thank you for your time and consideration.
Best regards,
Ilya
Hi,
I’m trying to detect whether my Safari Web Extension is running in Safari or Safari Technology Preview. Is there a reliable way to do that?
I can get the executable path of the parent process using proc_pidpath(). However, unlike Chrome or Firefox, Safari extensions run under /sbin/launchd as the parent process, not the responsible process (browser’s binary). In this scenario, I need the executable path of the actual browser process, but I haven’t found a way to get it.
Also, Safari doesn’t implement the Web Extension API’s browser.runtime.getBrowserInfo(), unlike Firefox.
I haven’t tested it yet, but I’m considering checking the user agent string, though I’m not sure how reliable that would be.
Use Case
Some users use my Safari extension as a web development tool and want to enable some features exclusively in Safari Technology Preview, while using other features only in standard Safari. If I could detect which browser is in use, I could provide the appropriate functionality for them.
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.
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
I have "http://localhost:8080" showing the index page I've created but php is not handled though an extension is running.
Haven't even tried mySQL yet but since there is no reference to it in https.conf the same problem will exist. Homebrew extension running also.
https.conf:
#PHP was deprecated in macOS 11 and removed from macOS 12
#LoadModule php7_module libexec/apache2/libphp7.so
There are no php.so files on my machine and again no mention of mysql
What should I enter in http.conf to activate these functionalities?
Thanks.

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 am trying to build and run a Safari Web Extension from Xcode and I have enabled "Allow unsigned extensions" in Safari settings. However, I see the below pop up:
And, if click on the "Quit and Open Safari Extensions Preferences..." button, the project stops running on Xcode and nothing happens.
What can be the issue? The extension works and runs fine if I get it from the Mac App Store and this only happens when running from Xcode. I even tried completely uninstalling the mac app store version and still facing the same issue.

We would like to confirm the unsubscribe flow related to recurring payment processing.
When a user unsubscribes, does your system send any notification to us?
If no notification is provided, we will not be able to detect the unsubscribe event and will continue to send recurring payment requests to the gateway periodically. Would this cause any issues?
We would appreciate it if you could share the specific unsubscribe flow with us.
Thank you in advance for your support.

Hello everyone,
We've had our app rejected twice under Guideline 3.2.2 regarding charitable donations, and we're seeking clarification on the correct implementation. We've read the guidelines but want to confirm the technical approach with the community's experience.
The Rejection Reason:
Apple states: "We still noticed that your app includes the ability to collect charitable donations within the app..." They specify that since we are not an approved nonprofit, we must use one of the alternatives, primarily: "provide a link to your website that launches the default browser or SFSafariViewController for users to make a donation."
Our Current (Rejected) Implementation:
User taps a "Help" button in our native app.
A native modal appears inside our app where the user enters their donation amount and email address for the receipt.
The user clicks "Donate," which then opens an SFSafariViewController to our website's payment page (e.g., Stripe, PayPal). The amount and email are passed as URL parameters to pre-fill the form.
Our Questions for the Community:
Is the issue solely the fact that we have a native modal for data entry? We understand we cannot process the payment in-app, but we thought collecting the intent (amount, email) was acceptable before handing off to Safari.
What is the definitive, compliant flow?
Option A: Should the "Help" button do nothing more than open an SFSafariViewController to a generic donations landing page on our website (https://ourwebsite.com/donate), with no data pre-filled? The user must then navigate and enter all information on the website itself.
Option C: The rejection also mentions SMS. Has anyone had success implementing a "Text-to-Donate" link instead of a web flow?
Wording: The button in our app currently says "Donate". Should this be changed to a more passive call to action like "Visit Website to Donate" to make it absolutely clear the transaction is external?
We want to ensure our next submission is successful. Any insight, especially from developers who have successfully navigated this exact rejection, would be immensely helpful.
Thank you.
