I'd like to know the install state of my iOS safari extension in the associated swift app. Is there any way to get this? As we have seen it is available for macOS here, is there anyway to know iOS Safari extension is enabled or not?
Thanks

Is this symbol, which Safari uses to the left of the address bar, in the public SF Symbols set? What's it called?
Hello,
In iOS 26 beta, we are seeing an unexpected behavior when using SwiftUI WebView (or a custom WKWebView via UIViewRepresentable).
When an alert is presented above the WebView, the WebView immediately reloads to its initial page. The alert itself also disappears instantly, making it impossible for the user to interact with it.
This issue occurs both with the new SwiftUI WebView / WebPage API and with a wrapped WKWebView. The problem was not present in previous iOS versions (iOS 17/18).
Steps to reproduce:
Create a SwiftUI view with a WebView (pointing to any URL).
Add a toolbar button that toggles a SwiftUI alert.
Run the app on iOS 26 beta.
Tap the button to trigger the alert.
Expected behavior:
The WebView should remain as-is, and the alert should stay visible until the user dismisses it.
Actual behavior:
As soon as the alert appears, the WebView reloads and resets to the initial page. The alert disappears immediately.
Minimal Example:
struct ContentView: View {
@State private var showAlert = false
var body: some View {
NavigationStack {
WebView(URL(string: "https://apple.com")!)
.toolbar {
ToolbarItem(placement: .topBarTrailing) {
Button("Close") {
showAlert = true
}
}
}
.alert("Confirm close?", isPresented: $showAlert) {
Button("Cancel", role: .cancel) {}
Button("Close", role: .destructive) {}
}
}
}
}
I'm using Xcode Version 26.0 beta 7
Thanks for your help.
I am new to PHP. I have developed my own web site with a lot of javascript in simple HTML files. I want to do some extensions with PHP but I can't make a simple web page function. I am sure something simple is wrong. Help!
Here is the test web page I made: hello.html
<html>
<head>
<title>Hello World</title>
</head>
<body>
<?php echo 'Hello World!'; ?>
</body>
</html>
Pointing Safari at hello.html gives me a new tab with the correct title, but no "Hello World" in the page itself.
Here is the output of php --version:

Hello,
I am experiencing an issue when trying to open the browser on my Apple Watch SE 2 running the latest version, watchOS 11.6. When I attempt to visit any website, the browser opens and displays the URL at the top as if it is loading, but the screen remains black and no content is displayed.
The internet connection is available, and all other apps on the watch work normally. This issue occurs only with the browser.
I would appreciate any guidance or solution to resolve this problem.
Thank you for your assistance.
Whenever I make a safari view controller on XCode26 Beta 5, there appears to be a blurry white overlay overtop the controller. This worked fine in XCode26 Beta 2, with no code differences.
Anyone have any suggestions?
Our iOS app uses React Native Webview (based on top of WKWebView) to display content. This webview stays in memory throughtout the app's lifecycle. We are observing a high number of webview content process terminations - around 15% of our sessions. (https://developer.apple.com/documentation/webkit/wknavigationdelegate/webviewwebcontentprocessdidterminate(_:))
What could be the reasons for it? Is there a way to know for sure?
Is the 15% of sessions number something that other apps also experience, or should this be lower?
Thanks!

Problem
As the title says, Safari lost all my tabs once I updated to macOS 15.4. I do of course have "Safari opens with: All windows from last session" set. This has been my default for many years.
Past Mitigation
In the past I had a script that I could use to backup ~/Library/Safari that would save all my bookmarks and tabs. Unfortunately they made this method of backup non-function sometime around when tab groups were introduced.
Suggestion
Fortunately my tab groups are still intact. But this sort of problem doesn't give me a lot of confidence. I haven't had something like this happen in a while, but when it does happen, it's quite frustrating. Apple really needs to recognize that this sort of thing can and will happen and they should make it easier for users to manually save/restore their tabs.
Problem with forums
To add insult to injury, as I was typing this message in the forum, I decided to select "Edit Bookmarks"... which proceeded to replace the current window with my bookmarks, thereby losing my post! It did this without warning of page content changes (which I get from most other websites).
I felt somewhat relieved that the forum had recognized a previous draft and offered for me to continue. However, when I selected it, it brought me back to an old post... that was actually posted!
smh
//Is my post method correct because google and claude are telling me I must use content type for the json and use .setvalue. I thought that my process was correct because I encode the data to turn into json and then make the request
func createTask(_ task: Task) async throws -> Task {
if let url = URL(string: "(baseURL)/todos"){
var request = URLRequest(url: url)
request.httpMethod = "POST"
let encoder = JSONEncoder()
do{
let data = try encoder.encode(task)
request.httpBody = data
let (data, response) = try await URLSession.shared.data(for: request)
return task
//we want to make encoder and then turn the data into json and put it in body
}
catch{
throw JSONErrors.encodingFailed
}
}
else{
throw URLError(.badURL)
}
}
I'm converting a Chrome Extension to a Safari Web Extension, I found it's not easy to get favicon of current tab/url natively.
The tab object in Safari doesn't have favIconUrl.
{
	"id": 121,
	"index": 6,
	"active": true,
	"width": 1324,
	"audible": false,
	"url": "https://github.com/",
	"mutedInfo": {
		"muted": false
	},
	"windowId": 2,
	"title": "GitHub",
	"incognito": false,
	"pinned": false,
	"height": 935,
	"highlighted": true,
	"status": "complete"
}
		
2. I didn't find Safari has similar thing like chrome://favicon
3. I found Safari's favicon caches in ~/Library/Safari/Favicon Cache/favicons but have no idea how to use them in Safari Web Extension.
Hi there,
I have a popular open source app called Foqos. What I'm finding in iOS 26 (might even effect older versions) is that when using the webcontent api within Managed settings as the following:
store.webContent.blockedByFilter = .specific(domains)
It doesn't work on Safari, but does work on third party applications like chrome, firefox, etc.
But when using the all and exception enum like the following
store.webContent.blockedByFilter = .all(except: domains)
This does work on Safari
This is pretty inconsistent behavior of the API and should be fixed to match the documentation. Documentation does not mention anything about Safari limitations
Again source code is open: https://github.com/awaseem/foqos
You can run the app yourself and find the same issues. Is anyone else experiencing this?
Since Safari requires a macOS app as a container for Web Extensions, is there a way to establish native messaging directly from SafariWebExtensionHandler using stdin/stdout? Or does Safari enforce a different communication mechanism?
I’d like to keep the same approach as other browsers.
Any guidance on making this work would be appreciated!
Our current iOS application utilizes WKWebView to display a web application. We've observed intermittent deletion of non-expired 1st-party persistent cookies within this web application, leading to session drops.
Here are our environment details and specific questions:
Environment:
App Build: Built with Xcode 16.2.
WebView Class: WKWebView.
Cookie Type: 1st-Party Persistent Cookie (Explicit expiration set, not a session cookie).
Domain Configuration: The content server and the cookie-issuing server are the same (same IP address, same eTLD+1). The Cookie is set via the Set-Cookie HTTP Header on the server side.
Questions:
Automatic Deletion Policy: Are there any scenarios (e.g., related to iOS system behavior, Safari policies, or Intelligent Tracking Prevention (ITP)) where iOS or Safari might automatically delete non-expired 1st-party persistent cookies used by WKWebView?
Deletion Conditions: If the answer to Q1 is Yes, under what specific conditions (e.g., memory pressure, inactivity, storage limits, specific ITP criteria) does this cookie deletion occur, and does the behavior differ significantly across various iOS versions?
OS Update Impact: Are there any known specifications or documented cases where an iOS version update itself triggers the mass deletion of existing cookies stored in the WKWebsiteDataStore?
Mitigation Strategy: If this automatic deletion is a known behavior, what mitigation strategies are officially recommended to ensure the persistence of essential 1st-party authentication cookies (e.g., manual synchronization with WKHTTPCookieStore or Keychain/UserDefaults)?
Official Documentation: If the answer to Q1 is Yes, please provide URLs to any official Apple documentation or technical notes that detail the specifications or behavior of 1st-party persistent cookie deletion within WKWebView.

Hello,
I'm using Safari 18.2 on Sonoma 14.6.1.
I was using the Developer Tools to do a Local Request Override in the Source tab for a CSS file that had a changing query string. I thought I had a good regular expression to catch all variants, but apparently it was too generic and possibly wrong, and made both Source and Network tabs no longer work in my Safari.
The regular expression I entered for the Local Request Override was: //build/style.css(?.*)?$
Now my dev tools is broken to the extent that the Source and Network tabs no longer work. The slide-out panel on Source that shows Breakpoints, LocalOverrides, etc no longer shows. The toggle for it does, but does nothing now. UI in general looks a little wack on both tabs.
So, since I can't turn off the Local Request Override, I've been trying to locate where Safari may have stored it to manually delete it. Not having a lot of luck on that front.
It seems to me that Safari was unable to escape my regular expression correctly and it then causes additional issue. Just a guess though.
Any advice or help in getting Safari Source & Network working again / manual removal of the LocalOverride would be greatly appreciated. I'm fluent in OSX and Linux, but grep was not much help surfacing anything that worked.
Thanks in Advance, possibly a Safari bug as well.
Even default Safari Web Extension project is not displayed on iOS 18.4 simulator ("No extensions installed"), so it's not possible to test extensions in simulator, only on real device.
In iOS 26.4 beta, I noticed that when loading pages using WKWebView and using WebSocket to establish IP type addresses, the connection duration was several seconds and sometimes even failed to connect (normally, the connection duration should be in milliseconds). However, when establishing WebSocket connections using domain names, the connections were normal.
Additionally, I discovered a special scenario:
When directly establishing WebSocket connections using IP type addresses, it remained in the "connect" state. At the same time, based on Wireshark packet capture, it was found that no TCP connection was sent at this time. However, if two connections with the same address were established simultaneously, those two connections could successfully connect.
This bug has seriously affected the use of my application service. Is there a chance that this version will solve the problem?
When using iOS 26.2 (23C55) Safari, the following can occur.
The current tab (A) opens a new tab (B) via window.open(url, target, windowFeatures).
The user clicks the "back" button to close tab B, and returns to tab A.
Tab A attempts to open tab B again at a later point, using the same "target" as before, and fails (no window object is returned by window.open).
This bug only occurs when the target is the same as the previously closed tab (which was closed via the back button). If a new target is specified, the new tab opens as expected.
This bug is also limited to the back button. If the user manually closes tab B, then it can be re-opened by tab A using window.open using the same target as before.
When using passkeys stored in iCloud Keychain (Passwords app) via Passkey Autofill in browsers other than Safari, the userVerification parameter is ignored and user verification (UV) is not performed.
As a result, relying party servers that require userVerification = required fail validation because the UV flag is not set, causing passkey authentication to fail.
This issue occurs when the following setting is disabled:
Settings → Face ID & Passcode → Use Face ID For → Password AutoFill
The issue is reproducible only with the following combination:
Non-Safari browsers (e.g. Chrome)
Passkeys stored in iCloud Keychain (Passwords app)
Passkey Autofill
The issue does not occur in the following cases:
Safari with passkeys stored in any credential manager
Non-Safari browsers using credential managers other than iCloud Keychain
Steps to Reproduce:
Go to Settings → General → Autofill & Passwords, and enable the Passwords app under “Autofill From”.
Go to Settings → Face ID & Passcode → Use Face ID For, and disable “Password AutoFill”.
Open Chrome and navigate to https://webauthn.io
Enter a username and tap “Register” to create a passkey using the Passwords app (iCloud Keychain).
On webauthn.io, go to Advanced Settings → Authentication Settings, and set “User Verification” to “Required”.
Reload the page, tap the input field, and perform Passkey Autofill.
User Verification is not triggered, and “Authentication failed” is displayed on webauthn.io.

This issue has already been reported via Feedback Assistant as FB21756948.
I am posting here to confirm whether this behavior is working as intended or represents a bug, and to make other developers aware of the current behavior.
iOS Safari 18.4/18.5 with IIS Windows Authentication with negotiate hangs after entering credentials
I don't think the issue is specific iOS 18.
We have a web application that runs with IIS Authentication of Windows and Anonymous. Initially the app opens and the user clicks a button and triggers the "401 Challenge" via ASP.NET. The browser presents the Active Directory login, user enters credentials, clicks Sign In, and the browser hangs (may actually be negotiating something). After a few minutes the user is logged into the application.
We have done a number of google searches/AI to try to determine what to change and there is no clear solution. Is there anything else to try?
This problem is not seen in Chrome on iOS or on a Windows machine. Strangely it is also not seen using BrowserStack with one of their "real" devices.
We have other apps that run with just Windows Authorization and this problem is not observed.
