Safari Version 14.0.1 (16610.2.11.51.8)
I am porting a Chrome/Firefox/Edge extension to Safari Web Extension. Mostly, the process was painless, I am, however, seeing quite different behavior in the tab ids generated by Safari compared to Chrome, Firefox, and Edge. My extension has callbacks for each of these browser.webNavigation events:
browser.webNavigation.onBeforeNavigate
browser.webNavigation.onCommitted
browser.webNavigation.onDOMContentLoaded
In each of these I rely on the tab id for various future tab targeting operations. When opening a new tab, the details object passed to each of these callbacks has a non-zero tabId on Chrome, Firefox, and Edge. However, in Safari, the tabId is always zero. To debug, I added one more callback:
browser.webNavigation.onCompleted
At this point Safari finally has a non-zero tabId in the details param. Needless to say this is causing some consternation with achieving the same outcomes as tab tracking on Chrome, Firefox, and Edge. It's like Safari is treating new tabs as "non tabs" until navigation completes. You can even see it when trying to get the tab by tabId=0:
browser.tabs.get(tabId) // tabId=0 here
	.then(tab => {
		// tab is undefined
	});
Seems like this might be a bug. I can't imagine why the behavior is so different from other browsers. Any ideas on how to work around?

Is the new Observations API for WebPage not available in Beta 1 as demoed in the WWDC video? I get this error even though Observation is imported.
hi
Testing on OS26 Public Beta 6.
In Safari, if you enter x homepage and scroll, the tab bar sticks to the bottom and moves.
Make the keyboard appear in the search window
When scrolling down on the Safari homepage again, the issue of not being able to stick to the bottom appears.
Is it because the liquid glass UI was applied this time? and safari bug?
Please let me know if I'm missing anything

Hello - we have a Mac application that uses a browser extension and the web extension JS APIs to communicate with Safari. During user testing we found that the tab title and tab URL properties are empty when obtaining the set of open windows via windows.get() after a Safari restart. We are testing with Safari 18.4 (20621.1.15.11.10). We have made a TestFlight version of our app and extension available to help with testing: https://testflight.apple.com/join/Va8Zdv9d. Screenshot and screen recording are attached to the Feedback ID supplied below.
STEPS TO REPRODUCE
Install Tabby via the TestFlight link
Enable the Tabby for Safari extension in the Safari extensions dialog
Grant permissions for Tabby for Safari to all windows all the time
Within Safari, open two windows each with at least two tabs
Within the Tabby app, ensure you see the windows and tabs listed correctly (tab title displayed for each)
Quit and restart Safari
Expected behavior
Safari re-opens existing windows and Tabby displays title for each tab
Observed
Safari re-opens existing windows but within Tabby all tabs except the current tab are displayed with a title of “Start Page”. Under the hood the tab title and tab URL properties are empty when returned via a windows.get() call after Safari restarts.

Environment
• Device: iOS 26 Developer Beta 5 (23A5308g)
• Xcode: 16.3
Short description
The app crashes the moment the user tries to long-press to select text inside a WKWebView, double-tap an image with Text (magnifier appears)
The exception is CALayer position contains NaN. frame = (nan,0;0,48) chorPoint=(inf, 0) and it is thrown in the UI process.
Build & run any project that hosts a WKWebView. Inject the following CSS via script (this is what we do to suppress the native callout menu):
WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.bounds
configuration:[WKWebViewConfiguration new]];
NSString *js =
@"document.documentElement.style.webkitUserSelect='none';"
"document.documentElement.style.webkitTouchCallout='none';";
[webView evaluateJavaScript:js completionHandler:nil];
[self.view addSubview:webView];

Hi, We are facing a major issue with our application. We are using FolioReaderkit to read epub files. Currently, it's working on the iOS 18.1 device and simulator, but it's not working on the iOS 18.2 and later version devices.
we are facing this error in Folioreaderkit
The passkey authentication dialog appears, and after unlocking with Touch ID, the dialog closes without any notification of success or failure.
This issue occurs with high frequency.
access to the https://passkeys-demo.appspot.com/
register account and create passkey.
logoff
access to the url again
you can see the passkey dialog
unlock device then the dialog disappears
nothing happens
reload the page
proceed 5) to 6)
nothing happens or success webauthn.

Hi Apple engineers!
We are making an iOS browser and are planing to deliver a feature that allows enterprise customers to use a MAM key to set a PAC file for proxy. It's designed to support unmanaged device so the MDM based solutions like 'Global HTTP Proxy MDM payload' or 'Per-App VPN' simply don't work.
After doing some research we found that with WKWebView, the only framework allowed on iOS for web browsing, there's no API for programmatically setting proxy. The closes API is the WKURLSchemeHandler, but it's for data management not network request interception, in other word it can not be used to handle HTTP/HTTPS request well.
When we go from the web-view level to the app level, it seems there's no API to let an app set proxy for itself at an app-level, the closest API is Per-App VPN but as mentioned above, Per-App VPN is only available for managed device so we can't use that as well.
Eventually we go to the system level, and try to use Network Extension, but there's still obstacles. It seems Network Extension doesn't directly provide a way to write system proxy. In order to archive that, we may have to use Packet Tunnel Provider in destination IP mode and create a local VPN server to loop back the network traffic and do the proxy stuff in that server. In other word, the custom VPN protocol is 'forward directly without encryption'. This approach looks viable as we see some of the network analysis tools use this approach, but still I'd like to ask is this against App Store Review Guidelines?
If the above approach with Network Extension is not against App Store Review Guidelines, I have a further question that, what is the NEProxySettings of NETunnelNetworkSettings for? Is it the proxy which proxies the VPN traffic (in order to hide source IP from VPN provider) or it is the proxy to use after network traffic goes into the virtual private network?
If none of the above is considered recommended, what is the recommended way to programmatically set proxy on WKWebView on an unmanaged device (regardless of where the proxy runs, web-view/app/system)?
From a mail app or similar, when opening a webpage in Safari as an external browser, JavaScript on the webpage stops running if Safari goes into the background. Is there a way to prevent this from happening?
Sample code for the counter:
Behavior: Upon returning from the background, the counter continues for about 7-8 seconds but does not progress further.
For example, if Safari is kept in the background for about 20 seconds and then brought back, the counter stops at around 7-8 seconds and only resumes counting after returning to the foreground.
Expectation: The counter should continue running even if Safari goes into the background.
The crash is specific to iOS 26.2 WKScriptMessageHandler delegate func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage)
Name attribute is accessible but WKScriptMessage body attribute causes crash
The object seems to be not accessible
I'm a web developer of WebRTC based web app for video and audio calls. After updating to iOS 26.1 beta I noticed, that my app can't use microphone anymore.
When I'm calling to getUserMedia with audio set to true, Safari returns error "No AVAudioSessionCaptureDevice device".
Other WebRTC demo apps also can't access microphone on this firmware.
And maybe it's connected somehow, but safari can't detect connected AirPods Pro 2 as an input device.
So, this bug brakes any WebRTC app, that uses microphones.
I am reporting what appears to be a serious integrity flaw in Safari under iPadOS 26.3 (and lower) that materially undermines the reliability of Screen Time parental controls.
This is not merely a UX inconsistency but a functional contradiction within a system explicitly marketed and positioned as secure parental control infrastructure.
Device / Environment
Device: iPad Air M3 13" (2025)
OS: iPadOS 26.3
Safari (system version)
Screen Time enabled with active restrictions
Child account (10 years old)
Background
We deliberately chose an Apple device for school use based on the expectation that Apple’s system-level parental control mechanisms — especially Screen Time — are robust, tamper-resistant, and technically consistent.
Screen Time is configured with:
App limits
Downtime
Parental controls enabled with limited web content restrictions (school requirements prevent strict blocking)
Safari enabled (mandatory for educational use)
further parental control restrictions
Because aggressive website blocking would interfere with legitimate school activities, monitoring Safari browsing history is a central supervisory mechanism.
When Screen Time is active:
Clearing the entire browsing history via Safari is correctly blocked.
Clearing history via system settings is correctly blocked.
The system explicitly communicates that deletion is not permitted due to Screen Time restrictions.
This behavior establishes a clear user expectation:
Browsing history is protected against manipulation.
The Issue
Despite the above safeguards, individual browsing history entries can be deleted easily and silently through the address bar suggestion interface.
This creates a structural contradiction:
Full deletion is blocked.
Selective deletion — which is arguably more problematic — remains possible.
Steps to Reproduce
Enable Screen Time with restrictions that prevent deletion of browsing history (for example on a student device with a child account).
Open Safari and visit any website.
Confirm it appears in Safari history.
Tap the Safari address bar.
Type part of the URL or page title.
Safari suggests the previously visited page below the address bar.
Swipe left on that suggestion.
A red “Delete from History” button appears.
Tap it.
Actual Result
The entry disappears immediately:
No Screen Time PIN required
No authentication request
No warning
No restriction triggered
No parental notification
No audit trace visible
Deletion occurs silently and irreversibly.
Expected Result
When Screen Time is configured to prevent browsing history deletion:
Individual entries must not be deletable
Deletion must require Screen Time authentication
Anything else defeats the protective purpose of the restriction.
Real-World Impact
In practical use, this allows minors to selectively sanitize browsing history while preserving a seemingly intact record.
In our case, this method is widely known among classmates and routinely used to conceal visits to gaming or social media platforms during school hours.
The technical barrier to exploitation is negligible.
This results in:
A false sense of security for parents
A discrepancy between advertised functionality and actual system behavior
A material weakening of parental control integrity
When a system explicitly blocks full history deletion but permits silent selective deletion, the protection mechanism becomes functionally inconsistent and unreliable.
Given that Screen Time is publicly positioned as a dependable parental control framework, this issue raises concerns not only about implementation quality but also about user trust and reasonable reliance on advertised safeguards.
Request
Please classify this as a parental control integrity and trust issue.
Specifically:
Disable individual history deletion while Screen Time restrictions are active
OR
Require Screen Time passcode authentication for deleting single entries
Screen Time is presented as a secure supervisory environment for minors.
In its current implementation under iPadOS 26.3 and before, that expectation is technically not met.
This issue warrants prioritization.
I’m experiencing a crash in WKWebView on iOS 26 Developer Beta 5 and Beta 6 with the following exception:
CALayer position contains NaN: [nan 65]
The crash occurs when the following CSS properties are applied to content displayed in WKWebView:
-webkit-user-select: none;
-webkit-touch-callout: none;
This issue happens consistently whenever these styles are set, leading to the crash inside WKWebView.
Is this a known bug in the current iOS 26 betas, or is there a recommended workaround?
Trying to implement my own forward/back buttons for the new SwiftUI WebView and reading the documentation I’m totally lost.
What’s the recommended way of implementing forward/back behavior with this component?
Starting with iOS 26.2, when Safari tabs are set to Bottom or Compact view, some pages are not rendering properly. The error does not occur in Top view.
For some pages, scrolling causes rendering to be very slow, causing the user to experience page breaks and missing parts. If the user waits a few seconds, the missing parts of the page will appear, but the issue will reoccur when scrolling further. We have tested this on all available iOS devices and the issue occurs on all iPhones running iOS 26.2. The issue does not occur on iOS 26.1, and we have not experienced it on devices running iOS 18.
The issue can be reproduced on the following pages with an iPhone running iOS 26.2:

https://oktatas.kurzusguru.hu/products/course/az-online-kurzuskeszites-alapjai
iPadOS 26, dark mode
Open Safari
Search for anything or open a website that has white background
Kill Safari
Open Safari again
I still can reproduce it with Safari on iPadOS 26.0.1
This issue also happens to my app when opening a HTML/JS on WKWebView with white background while using dark mode. I did send a feedback ticket when using iPadOS 26 beta but havent seen any reply. This is my first time sending a feedback so I dont know if Apple would reply or not.
I am trying to setup web sign in with apple, I have an active apple subscription and have set up all necessary things. I made a service id in apple Identifiers, connected to existing primary id (also has apple sign in enabled). I have my domain set up also correctly but still I cant generate the code due to invalid client. What do I need to do?
I have also tried recreating the service ids multiple times with no luck.
my init is
AppleID.auth.init({
clientId : '[CLIENT_ID]',//used the service id one not app id
redirectURI : '[REDIRECT_URI]',
usePopup : true
});

I'm working on a web browser App that's distributed via the App Store. This app renders web pages using WKWebView.
Our users are requesting a way for us to allow them to play videos in Picture in Picture. After some investigation, we noticed that in order to allow PiP videos in our browser in the sandboxed environment, we need to add the com.apple.PIPAgent entitlement under the com.apple.security.temporary-exception.mach-lookup.global-name option.
We tried to submit our app with this entitlement, but unfortunately, we were rejected:
Guideline 2.4.50) - Performance
We've determined that one or more temporary entitlement exceptions requested for this app are not appropriate and will not be granted:
com.apple.security.temporary-exception.mach-lookup.global-name
com.apple.P|PAgent
We would like to have access to this entitlement so we can offer PiP to our users.
We already created a radar about this as well: FB13814428
Additionally, we have another radar (FB13557716) regarding allowing the usage of a private flag _allowsPictureInPictureMediaPlayback, which would also be required to enable us to use PiP.
Is there any way in which we can currently enable PiP? Would opening a TSI help here?

Since iOS 18.1 launched as a beta, we've been getting reports from end users on iPhone 15 Pro and iPhone 15 Pro Max specifically. They're reporting that our WebView is unable to load our local HTML content. I'm curious if anyone else has had their app or users run into this issue?
So far I've tried installing the most recent XCode Beta 16B5014f and installed an 18.1 emulator, but our app worked fine. It's also working fine on all my real devices, but we don't have a 15 Pro to test on. I'm curious if this is related to the processor on these devices and how they are intended to support Apple's new AI coming in 18.1.
