How can i add Authorization header to a wkwebview. I checked https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 which says Authorization header is a reserved http header and shouldn’t be set. I want to set it when requesting a url in wkwebview for authentication purpose?

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.
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">
<style>
html,
body {
margin: 0;
padding: 0;
background-color: #363636;
}
#just-a-bird {
position: fixed;
bottom: -100px;
width: 300px;
height: auto;
background: red;
}
</style>
</head>
<body>
<img id="just-a-bird"

</html>
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!

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.

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.
This is the code suggested by Grok 3 Beta, but I see this error:
Error: First parameter passed to Document Constructor must be an object.
function run(input, parameters) {
var Safari = Application('Safari');
Safari.activate();
// Open the AEMO data dashboard (Grok 3 Beta recomendation opens the web page correctly)
Safari.Document().make();
Safari.windows[0].currentTab.url = 'https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem';
delay(10); // Wait for page to load
// Click the Fuel Mix tab (target the active in the tabs)
Safari.Document(0).doJavaScript("document.querySelector('.tabs .active').click()");
delay(5); // Wait for tab content to load
// Select 48 hrs from the dropdown Safari.Document(0).doJavaScript("document.querySelector('#interval').value = '48H'; document.querySelector('#interval').dispatchEvent(new Event('change'))");
delay(5); // Wait for selection to take effect
// Click the download button Safari.Document(0).doJavaScript("document.querySelector('.visualisation-icon-button').click()");
return input;

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) {}
}
}
}
}

Thanks for your help.
Hello all,
As you may know, the company ProofPoint is an Apple partner, and is engaged (I think) to reduce misuse of icloud emails.
We have two servers solely set up for our web-app, which is a specialised forum for apartment owners.
The new servers were established about the same time, with the same provider, with clean new IP addresses - and as mentioned above, are only used for this web-app.
During a testing phase a YEAR ago, we became aware that our in-house icloud emails weren't receiving notifications via the app, and further investigations revealed that the cause was that ProofPoint had placed a block on that server's IP.
We immediately, via their website form initiated a Support Ticket, which, the site indicated was lodged, BUT we have never received any response to that Ticket, nor have we received any response to four subsequent Tickets we initiated - nothing. In over a year!!
Yesterday, we contacted Apple support, but the devices area of support is the main section and they said it wasn't an issue they could assist with.
Some relevant matters:
SPF: DKIM: DMARC:
are, I believe all configured correctly (and Gmail gives a PASS to all of them).
The IP is not blacklisted by any list we are aware of.
Our other server's IP isn't blocked by ProofPoint.
So, literally at wits end, I'm reaching out to the developer subscribers here to see if they have any suggestions for us.
We currently are unable to accept any new subscriber that is using an icloud email address, and that's an absurd situation to be in.
Surely we don't have to go to the trouble and inconvenience of obtaining a new IP because of this!!! But when we can't get ANY response to the Support Tickets, it's really hard.
Thanks

Can someone please help me: I do not have the brain space (85yo) to figure out an Apple Script or Java Script app to do this simple task.
I have spent a few hours each day, over several days, and have made zero progress on such an apparently simple task.
I wish to create an Automator App for the macOS Safari browser that will schedule (via a Calendar Event) the download of the 48hr data behind the hourly Fuel Mix Plot Data from the AEMO Web Site, every Monday, Wednesday, Friday and Sunday.
Here is the link to the AEMO web site:
AEMO, Energy Systems, Electricity, National Electricity Market (NEM), Data (NEM),Data Dashboard
https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem
The 48 hour hourly Fuel Mix data is found by selecting the "Fuel Mix" button (which by default will display the NEM Current Trend).
The 48 hour trend is displayed by tapping on the small "Current" pulldown menu, and selecting "48 hrs".
The 48hr Data is down loaded by selecting the small circular button just to the right of the pulldown menu.
a) AEMO Web Site: https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem
b) Main Menu, and underlying html,
c) Fuel Mix menu, Pulldown list, DownLoad button, and underlying html,
I am familiar with C++ and have built Xcode Apps, and used Excel Macros extensively in the past.
Thank you.
Robert.
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.
I develop a tab manager extension: https://apps.apple.com/ua/app/tab-finder-for-safari/id6741719894
It's written purely in Swift. All Safari interactions are done solely inside a SFSafariExtensionHandler .
But now i'm considering adding some features from Google Chrome's Extension API like window switching.
Is it possible to add a background.js worker to my existing Safari App Extension to have access to the beginRequest method override inside SFSafariExtensionHandler?
Without converting my extension from Safari App Extension to Safari Web Extenion?
I have a simple Safari extension which contains only Javascript and no native code.
Currently I have the placeholder SafariWebExtensionHandler.swift that Xcode created when I added the extension. It's not doing anything useful, but simply deleting it doesn't seem to work.
Can I have an extension that includes no native code?
When the “Use Strong Password?” dialog appears and I select “Not Now” to manually enter my own password, the password I type is displayed in plain text instead of being masked. Since the input field is of type="password", the entered characters should be hidden as is standard for password inputs.
Is there a way to prevent this behavior and ensure that the password is properly hidden even after dismissing the strong password suggestion dialog?

Hi, this is my first post in the community, so please correct me if i am posting this somewhat in a wrong manner.
Im using my Apple M1 Pro(14inch, 2021) and installed the os 26 yesterday.
Today, I was using Safari, and all of sudden it gets frozen, then the following window popped up.
Is this something expected? i.e. my usage is somewhat unusual or is there any report around potential memory leak in Safari? appreciate any suggestions, as Safari is my main browser and currently on hold due to this issue. Thanks
Hi everyone,
We work on a macOS plugin which then gets loaded into another application. I'm trying to load a webpage in that application through our plugin using a WKWebView & I set my class as the navigationDelegate for the same. I do not receive any callbacks for the WKNavigationDelegate methods. I have debugged & made sure that the navigationDelegate is actually set to my class. Here is a sample code of what I'm doing :
[[NSApplication sharedApplication] runModalForWindow:self.mWindowController.window];
- (void)windowDidLoad
{
[super windowDidLoad];
[self.window makeKeyAndOrderFront:self];
[self.window orderFrontRegardless];
if (self.mLoadingView == nil)
{
self.mLoadingView = [[LoadingView alloc] initWithFrame:[[self.window contentView] frame]];
}
[[self.window contentView] addSubview:self.mLoadingView];
[self.mLoadingView showLoadingView];
[self.window setLevel:NSMainMenuWindowLevel];
[self loadWebPage];
}
-(void)loadWebPage
{
[self.mWKWebView setUIDelegate:self];
[self.mWKWebView setNavigationDelegate:self];
[self.mWKWebView stopLoading];
NSURL *lURL = [self samplePageURL];
WKNavigation *lNavigation = [self.mWKWebView loadRequest:[NSURLRequest requestWithURL:lURL]];
}
- (void)webView:(WKWebView *)pWKWebView
didFinishNavigation:(WKNavigation *)pNavigation
{
[self removeLoadingview];
[self.mWKWebView evaluateJavaScript:@"document.body.setAttribute('oncontextmenu', 'event.preventDefault();');" completionHandler:nil];
}
I do not get any calls in the webView:didFinishNavigation: & I also tried other methods like webView:didStartProvisionalNavigation, webView:didFailProvisionalNavigation:withError: etc but did not receive any call in those either. Instead of runModalForWindow: if I use showWindow: on the mWindowController the webpage somehow loads but I still don't get any callbacks & so the loadingview subview is also present. The WKWebView is placed in a storyboard, and I have an IBOutlet connected to it in my class.
Has anyone faced a similar issue or can point me to something I might be missing? All help is appreciated. Thanks in advance.
Is this symbol, which Safari uses to the left of the address bar, in the public SF Symbols set? What's it called?
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.
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?
