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.

Does webkit have a way to display a smart banner for a home screen web app similar to how a smart banner can be displayed for native apps?
I recently noticed (10/23) that Twitter showed a smart banner encouraging Home Screen web app on my Mac running Sonoma.
How is this done?
Chrome's Incognito mode can not open app from universal link on iOS. It's opened a web page instead of launching the app even the app already installed on the iOS device.

Hi, I am developing the Click & Read web add-on for Chromium, Firefox and Safari. We use xcrun safari-web-extension-converter tool to generate the Safari add-on, with up-to-date MacBook MacOS, Xcode et Safari : Sequoia 15.3.2, Safari Version 18.3.1 (20620.2.4.11.6), XCode Version 16.0 (16A242d).
We have updated our addon to Manifest v3, having the Background script as Server Worker
"background": {
"service_worker": "background.js",
"type": "module"
}
self.addEventListener("activate", (event) => {
console.info("Service Worker activated", event);
event.waitUntil(
self.registration.pushManager
.subscribe({
userVisibleOnly: true,
applicationServerKey: urlBase64ToUint8Array(
process.env.VAPID_PUBLIC_KEY
),
})
.then(async (subscription) => {
console.info("[Service Worker] Extension is subscribed to push");
const { subscription: savedSubscription } =
await getLocalStorageKeyData("subscription");
if (savedSubscription)
fetchApi({
url: `${API_SERVER_URL}/subscription/remove/${savedSubscription.keys.auth}`,
}); // Remove previous subscription from server on addon activate
currentBrowser.storage.local.set({
subscription: subscription.toJSON(),
}); // Save subscription in local storage
currentBrowser.runtime.setUninstallURL(
`${API_SERVER_URL}/subscription/remove/${
subscription.toJSON().keys.auth
}`
); // Set uninstall URL to remove notification subscription on addon uninstall
fetchApi({
url: `${API_SERVER_URL}/subscription`,
reqInit: {
body: JSON.stringify(subscription.toJSON()),
method: "POST",
headers: {
"Content-Type": "application/json",
},
},
});
})
.catch((error) => {
console.error("Push subscribe error: ", error);
}) // Subscribe to push notifications
);
});
When trying to subscribe the addon instance to our Push server, we get this error : Push subscribe error: NotAllowedError: User denied push permission
Our NodeJS backend is using the web-push librabry : https://github.com/web-push-libs/web-push) to save subscriptions and make notifications push.
By looking for same errors on forums, the best hint I found is that it could be related to the testing is done on localhost (addon is built from XCode onto Safari, and Push server is running on localhost).
Thanks for your help !
After updating to iOS 18.4, our web application (with service workers) crashes on devices that accessed it prior to the update. This issue also affects hybrid mobile apps using the same web application; reinstalling the app resolves it by refetching and reinstalling service workers. Debugging is challenging because clearing the cache or reinstalling the app fixes the problem, and no useful error logs are available. Has anyone encountered similar crashes related to service workers after an iOS update and have any insights into the cause?
An Administrator account is executing safaridriver --enable but it doesn't apply to other standard user accounts and standard accounts can't enable it directly. Is this expected behavior? How can standard users make use of safaridriver?
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.
Hello Apple App Review Team,
We are using Privy to enable sign in with Farcaster in our app. Privy is a 3rd party authentication SDK, and it currently opens the authentication URL using the system browser.
Unfortunately, this behavior is handled internally by Privy and we do not have access or control to override it in order to present the sign-in flow in-app using SFSafariViewController.
We understand the importance of maintaining a seamless and secure user experience, and we fully support the use of SFSafariViewController or ASWebAuthenticationSession. However, since Privy does not expose an option to change this behavior at the moment, we are limited by their current implementation.
We have reached out to the Privy team requesting a change or improvement that would allow us to use SFSafariViewController instead of the external browser. In the meantime, we would appreciate your guidance on how to proceed, or whether an exception could be granted due to this 3rd party SDK limitation.
Thank you for your understanding and support.
I have multiple web views of the same domain that share the same local storage, as expected.
One of them though, is loading a .webarchive file.
The web archive is of the same domain, and is loaded using the same base URL.
For some reason, in most cases, the local storage is not shared with this web view when loading the web archive, although if I make that same web view load the actual live web page it does share local storage.
I say in most cases, because for some users it works as expected, but for a significant portion of users it isn't sharing local storage.
I think that the main difference between working and not is iOS version. iOS 17 seems to be able to share the local storage but iOS 18 does not. I can't find anything related in the release notes of iOS 18 versions.
There is nothing in the documentation for load(_:mimeType:characterEncodingName:baseURL:), or the header file, that explains anything specific about local storage and webarchive loading.
Does anyone know for sure how local storage is handled when a webarchive is loaded into a web view, and did something change with iOS 18 in regards to this?
Hello all,
I'm trying to retrieve geolocation data on the web, but I'm having trouble with the altitude value, which seems to differ from what I get on Android.
When using navigator.geolocation.getCurrentPosition in Safari, is the altitude value based on mean sea level, or is it ellipsoidal altitude based on the WGS84 ellipsoid?
altitude (WebKit JS): https://developer.apple.com/documentation/webkitjs/coordinates/1631861-altitude
altitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/altitude
ellipsoidalAltitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/ellipsoidalaltitude
If anyone has any insight into this topic I would greatly appreciate it!
Howdy,
WKWebView feature request: allow Fullscreen API without User Gestures
similar to ElectronJS' userGesture: true flag that allows devs to bypass user gesture restriction for Fullscreen API and similar
executeJavaScript(code[, userGesture])
https://www.electronjs.org/docs/latest/api/web-contents#contentsexecutejavascriptcode-usergesture
afaik this is allowed because of a fairly recent update to Chromium that also allows users to give Fullscreen API permissions per domain
https://chromeos.dev/en/posts/using-the-fullscreen-api-without-gestures
Would be greatly useful for a use case in my cross-platform app, so I can avoid rewriting all platforms to use Chromium
Thanks
使用direct distribution进行分发时,safari web extension 在safari setting 中显示没有权限读取、修改或传输任何网页的内容。
但是我在看公证日志显示插件是正常的公证的
这导致safari extension 无法使用。

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.
Environment
• Device: any iPhone running 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];

I have a business scenario where I want to guide users to Safari and open a Safari extension. How can I open Safari from my app and navigate to a specific webpage?

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:
🔗 CodePen Demo
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!
Description
When creating an Apple ID via the web form, if the user’s chosen password contains their own name, the server correctly returns an error (e.g., "Password cannot contain your name") in the PUT request's JSON response. However, this error is not shown on the frontend, leaving users unaware of why the form silently fails or stalls.
Steps to Reproduce
Go to the Apple ID account creation page (https://appleid.apple.com/account).
Enter valid account details where the password includes the user's first or last name (e.g., Johnacb2331!l for a user named John Doe).
Complete all fields, including phone number verification and captcha.
Submit the form and monitor the Network tab in your browser’s DevTools.
Observe that the form appears to hang, loop, or silently fail.
Open the PUT request to /account — the response JSON will contain the relevant validation error (e.g., “Password cannot contain your name”), but the user is not shown this.
Expected Behavior
The password validation error (e.g., containing the user’s name) should be immediately displayed in the UI next to the password field to inform the user and allow for correction.
Actual Behavior
No error is shown in the UI. The form appears to fail silently, leaving the user confused. The actual reason for failure is only visible through browser developer tools in the PUT response payload.
Impact
This can lead to:
User frustration and confusion
Increased support overhead
Poor UX in a critical flow (account creation)
Environment
Browser: chrome 136.0.7103.114
Platform: Web (https://appleid.apple.com)
Date observed: 31/5/25
Suggested Fix
Ensure that password validation messages from backend responses surface in the frontend, especially for common user input issues like including names in passwords.
No screenshots as I can not create a new account

Hi everyone, i'm running into a problem with my personal domain being flagged as 'deceptive website' in safari, and i can't figure out how to fix it
Domain: neon0404.space
This is just my personal domain - i use it for adguard home, vaultwarden, some test stuff, sometimes small web tools for friends or family
Nothing illegal or malicious has ever been hosted there
On july 6, i launched a very simple web utility for a friend
when he opened it on ios safari, he got the red 'deceptive website warning'
I checked this on other different devices - all got the same warning
The next day (july 7) i submitted a review request via websitereview.apple.com, but got no reply
I did some digging and found that safari safe browsing daemon pulls data from google safe browsing, tencent safe browsing, and some apple's internal lists
So, going one-by-one
https://transparencyreport.google.com/safe-browsing/search showed up that domain is flagged for something shady
Signed up in google search console and saw my domain was flagged for 'malware links' (with no related urls listed), so looked like a false positive
I audited everything related to this domain on august 5 - nothing suspicious
Next day i requested a review in Google Search Console, just next day Google confirmed that everything is ok and removed the flag
So, i thought, maybe this was the key and requested another review via websitereview.apple.com (august 7)
No reply, domain still flagged
While i was waiting, i checked domain in Tencent (https://urlsec.qq.com/check.html) - no issues
Other services like VirusTotal, Norton and Sucuri showed up same result - no issues
I attempted to contact regular support (even though it's not their area of responsibility), but just in case
They, as expected, couldn't do anything
At this point it feels like a dead end, so i'm here
Has anyone been through this before?
Is there any other way to escalate the review process with apple?
Really appreciate any advice, as this domain is personal and linked to my username, which i want to use later
I build websites and my current build has seven videos on the first page built with the html 'video' tag. The page renders on all browsers and Android and on Safari on my mac but on my iPhone safari they appear black and then play correctly when clicked. This has changed since the last update.
