Hi! I'm trying to implement ASWebAuthenticationSession to log in to my app via the web app backend. However, I'm a bit confused about the cookies that this has access to. When I set prefersEphemeralWebBrowserSession=false it does not seem to use the cookies from Safari. Or at least, I'm logged into my web app in Safari, but when I use ASWebAuthenticationSession I still have to log in again. Does it not share session cookies with Safari?
I did notice that if I don't use an ephemeral session, once I log out and try to log back in my app does automatically log me in but that's actually unhelpful in my opinion because now I have no way to clear that session because it only lives in the ASWebAuthenticationSession context. If that's the case I may as well use the ephemeral session then because it seems to have only drawbacks.

Hi Developers,
I am working on a small project and I noticed that my website header looks different in Safari on macOS compared to Windows browsers like Chrome and Edge.
In Safari, the header text and spacing look slightly shifted (screenshot attached).
On Windows browsers, everything looks perfectly aligned.
Here is my live project for reference: https://gratuitycalculatorae.com/
Screenshot from Safari (macOS):
Is this related to Safari-specific CSS rendering?
Should I use -webkit- specific fixes or is there a better cross-browser solution?
Any guidance or best practices would be really helpful. Thanks

Hello,
As previous reports have already shown, there seems to be a few issues on the latest version of Safari, mainly around:
Modals taking up the full viewport
Elements positioned at the bottom of the screen
This also seems to affect the modals on apple.com/iphone.
I've recently done an analysis of what can and can't be done in code to work with the new liquid glass UI and thought I'd share my findings here.
The full write up, along with screenshots and the demos I used are available in this repository:
https://github.com/stevenocchipinti/liquid-glass-spike
A brief summary of the findings:
The conditions for a fullscreen modal overlay element to cover the entire screen with a position: fixed; seems to be:
The background must be semi-transparent
Solid colours, linear-gradients, etc. don't work
The container must be empty
This also means the standard and ::backdrop don't seem to work.
The conditions for a bottom sheet to cover the entire screen, including the area around the Safari toolbar seems to be:
The element must be positioned within 3px from the bottom of the viewport
The height must be within a certain threshold
If I've missed anything, please let me know.
It would be really nice to have some official documentation on these issues to explain to developers how to do this properly.
I'm using the new iOS 26 WebPage/WebView for SwiftUI in a NavigationStack. The initial load works as expected, but when loading items from the back/forward lists, the content jumps beneath the navigation bar:
struct WebPageTestView: View {
var webPage = WebPage()
var body: some View {
NavigationStack {
WebView(webPage)
.toolbar {
Button("Back") {
if let backItem = webPage.backForwardList.backList.last {
webPage.load(backItem)
}
}
Button("Forward") {
if let forwardItem = webPage.backForwardList.forwardList.first {
webPage.load(forwardItem)
}
}
}
}
.task {
webPage.isInspectable = true
webPage.load(URL(string: "https://domchristie.co.uk/"))
}
}
}
I have run this on the iOS 26.0 and 26.1 Simulators and get the same issue.
The demo website does not use any JavaScript.
I was able to replicate this behaviour using a wrapped WKWebView and calling the .ignoresSafeArea(.all) modifier.
iOS 26 introduced a significant step back for PWAs - you now need at least five taps to add a PWA to your home screen.
Android has excellent PWA support - it takes 1 tap to install an app, and the platform support is great, and web apps feel amazing. The gap between the platforms has now increased even further.
My team and I were hoping for better PWA support, but now we are very worried about the direction - it puts us in a difficult situation.
I'm sure many developers face a similar challenge.
What's the current status of PWAs in iOS? Is Apple aiming to improve its support in the near future? Is there a roadmap, tech previews, or betas addressing the issue?

I have had zero luck anywhere else and it’s at this point infuriating. February 23rd of this year I submitted a ticket in Feedback regarding how Safari for me has been broken. I can’t load any website at all, I have cleared cache, data, you name it. I have reset the phone after doing so and as I type this today on a brand new iPhone 17 Pro Max it still doesn’t work. Every single app that prompts a Safari window to sign in also doesn’t work and crashes just as Safari the app does. Sometimes I get a message that pops up that says “Webkit encountered an internal error” before it crashes. I can’t provide a screen recording or screen shots because Safari just crashes. I genuinely don’t know what to do or where to go for an answer and i’ve submitted seven updates to my open Feedback ticket since February 23rd 2025, spanning months from that original date and yet no change or help has came from it. I am clueless on how to even begin to go about fixing it and agitated because it’s been so long, so many other apps effected by this, even on a brand new device Safari still does not work for me. Any help at all would be greatly appreciated I used to have a 15 Pro Max but now on the 17 Pro Max and throughout the entire time i’ve been on the developer beta. Maybe that is the issue i’m unsure because now i’m just on iOS 26 so I don’t know if it’s just stuck like this forever. Again any help would be appreciated. I have not went physically to Apple yet to get this solved it‘s been a last resort, considering my options I might have to clear time to go. I’ve been using Chrome ever since this issue.
Hello from Leipzig, Germany!
I noticed that when vertically scrolling in Safari 26 on my Mac, the content of the website I am currently working on is visible in the tab and URL bar with a liquid glass effect. I then looked at various other websites. Some websites have an opaque top bar. Some websites have a transparent top bar where content is visible when scrolling. On the Apple website, the top bar is opaque in light mode but transparent in dark mode. Unfortunately, I can't find a way to control this behavior. Has anyone found out more about this?
When I open the browser in Safari on iOS 26, I want to specify the background color for the header notch (where the time, battery, etc. are displayed) and the footer indicator area.
Specifying the theme color in HTML as shown below did not change anything.
<meta name="theme-color" content="#ff0000">
<meta name="theme-color" media="(prefers-color-scheme: light)" content="#ff0000">
<meta name="theme-color" media="(prefers-color-scheme: dark)" content="#ff0000">
The HTML below specifies the background color as green, but is it necessary to specify the background color directly in the body like this?
Or is there some kind of metadata, like theme color?
<!doctype html>
<html lang="ja">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1" />

When using position: sticky; bottom: 0, the div is expected to stick to the bottom of the viewport when the browser toolbar hides while scrolling. However, it stops at the height where the toolbar was, instead of moving down with the disappearing toolbar.
In the image below, the red-bordered navigation shows the situation where it does not stick to the bottom.

I am using a custom PAC file in network settings and till now with Sonoma & Sequoia OS, it was working perfectly fine and I was able to redirect traffic to my proxy server.
After upgrading to MacOS Tahoe, this stopped working completely. What is happening now is no url is opening on my machine with Chrome & Firefox browser, but somehoe Safari is working. After checking, I found that my deployed network extension is intercepting traffic and allowing it to pass. But still, the pac file is not working.
Are there any changes done in MacOS Tahoe regarding this PAC file? How can I resolve this issue?
Bug Report:
Safari refuses to render content that is position: fixed or position: sticky if it goes below the iOS 26 navigation controls at the bottom of the browser. Since the controls are transparent and floating, this is a problem as fixed content is effectively unable to reach the bottom of the page. Attempting to move it below 100vh causes it to be cut off rather than rendering behind the navigation elements.
Here is some code reproducing the issue:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

Hi,
I am developing an OpenType font with the following cursive feature.
feature curs {
lookup cursivejoinrtl; # RIGHT_TO_LEFT flag set between Hah, Meem, Yeh and final Meem
lookup rehwawcursive; # RIGHT_TO_LEFT flag clear between Waw and Hah
} curs;
Here is the rendering of the word وحميم in TextEdit.
Using HarfBuzz I got the following result.
The same rendering problem occurs when using Safari. It seems that is related to Core Text.
I reported the issue to Feedback Assistant over a year ago but haven't had a response yet. So I'm posting the problem on this forum.
Any support on this matter would be greatly appreciated.

I have a WKWebView that contains a js text editor, built on top of a content editable div. Currently, inline predictions on Mac break the text editors functionality significantly every time there's a prediction. There's not a way for me to fix this on the js side unless I can know when a prediction is shown.
I've tried disabling inline predictions and writing tools with the web view config, but it doesn't work:
let config = WKWebViewConfiguration()
config.writingToolsBehavior = .none
config.allowsInlinePredictions = false
let webView = WKWebView(frame: .zero, configuration: config)
I've also tried disabling all spellcheck and autocorrect features in the html but that doesn't work either:
<div contenteditable="true" spellcheck="false" autocomplete="off" autocorrect="off" autocapitalize="off"></div>
Is there anything I can do to turn it off? Or, is it possible to know when the WebView is predicting text?
Hello all,
I'm building a web application in ASP.NET MVC (.NET Framework 4.7.2), from this web app I need to send push notifications to users. For the ones who are logged in with windows/android, everything works as expected, but I can't manage to get it work on the apple side.
If I use the same methods to subscribe to push notifications, it shows me the popup that asks the user to enable push notifications, and then I get an endpoint like this:
https://web.push.apple.com/QKC1Muic0H7...
It doesn't work using this (taking the part after https://web.push.apple.com/), I keep getting "Bad device token" (trying to send the notification via APNS).
Then I found out that there is another method to register the device from the frontend, and this one should give me the real device token:
window.safari.pushNotification.requestPermission
But this one doesn't show me the popup, it gives me "denied" without a reason.
I'm trying to a test application which is here https://pwa.vctplanner.it, the web push id is web.it.vctplanner, I created a push package downloadable from POST https://pwa.vctplanner.it/api/v2/PushPackages/web.it.vctplanner, and the code from the frontend is this:
function registerSafariPush() {
// Controlla se Safari Push Notifications è disponibile
if (!('safari' in window) || !('pushNotification' in window.safari)) {
console.log("Safari Push Notifications non supportate su questo browser.");
return;
}
// Il tuo Website Push ID registrato su Apple Developer
var websitePushId = "web.it.vctplanner";
// Controlla lo stato della permission
var permissionData = window.safari.pushNotification.permission(websitePushId);
switch (permissionData.permission) {
case 'default': // L'utente non ha ancora deciso
window.safari.pushNotification.requestPermission(
'https://pwa.vctplanner.it', // URL del server che serve il Push Package
websitePushId,
{}, // dati opzionali da inviare al server
function (permission) {
if (permission.permission === 'granted') {
console.log("Notifiche push abilitate!");
sendSubscriptionToServer({ endpoint: permission.deviceToken });
} else {
console.log("Notifiche push non abilitate dall'utente.");
}
}
);
break;
case 'denied': // L'utente ha negato
console.log("Notifiche push negate.");
break;
case 'granted': // L'utente ha già autorizzato
console.log("Notifiche push già autorizzate.");
sendSubscriptionToServer({ endpoint: permissionData.deviceToken });
break;
}
}
Any suggestions of what I'm missing? Is there a complete guide to how generate the push package?
Thank you

Reproducible in Safari, WKWebView, and UIWebView:
Yes
Actual behavior
In WebView (and identically in Safari):
Before the keyboard is shown, header/footer elements with position: fixed are correctly aligned with the screen viewport. Scrolling up/down works as expected.
After the keyboard appears, the visualViewport position changes.
Bug: When the keyboard is dismissed, visualViewport.offsetTop does not reset to 0. As a result, fixed header/footer elements remain misaligned:
When scrolling down, the position looks correct.
When scrolling up, the header/footer are visibly offset.
Steps to reproduce
Focus an input field → the keyboard appears
Dismiss the keyboard
Observe that visualViewport.offsetTop remains >0 (does not reset to zero)
position: fixed header/footer elements are misplaced relative to the screen
Expected behavior
After the keyboard is dismissed, visualViewport.height should return to match the layout viewport, and visualViewport.offsetTop should reset to 0.
When scrolling upward, fixed elements should remain correctly positioned within the layout viewport.

I've been using Sign In with Apple for Web for the last six months, and it works well enough.
Now, I'm updating the domain of the main application (we got the .com! yeah!)
However, I can't find a way in the configuration UI to update the allowed redirect URLs for the application.
I go to Identifiers -> My App -> Capabilities -> Sign In with Apple -> Edit button.
It just allows me to edit whether this is a primary ID, or grouped ID, plus a callback URL (which I'm not currently using.)
our company created a web safari extension.
before iOS 26 (beta) release we would archive our extension and install to our devices no problem.
since iOS 26 (beta) (we also tried in beta 4 23A5297m) the extension would archive perfectly but when installing the extension would just not run. its found in settings under safari extension, but when enabled the extension and open safari it will show error message "Ext" is no longer available.
to rule out all code issues, we built a new project from scratch with a new bundle id, tried to archive with no problem, but when installed in an iphone 16 with iOS 26 BETA (23A5297m) same error ocurs it installs but when opening safari it will give an error message saying extension is no longer available.
attached in the google drive link is a zip file of the new project, a zip file with a succesfull build of the ipa file with enterprise distribute, a video of the entire proccess and the error that the iphone gives.
also attached a log file from the iphone that includes the install and the crash of the app.
within the logs there is a log saying Error occurred during transaction: The provided identifier "dev.sacal.ext" is invalid.
before ios 26 the exact steps worked perfectly.
