Up until some point relatively recently, I have been able to use Safari's web inspector to connect to the iOS simulator in order to debug our web application in development at http://localhost:8088.
Now, the web inspector still OPENS, but it opens in a broken state. The context is available to select from Safari's "Develop" menu: Develop > "iPhone 16 Pro (Simulator)" > "localhost - login". It appears under the Safari heading if I have navigated to the web app in the browser, or under the Expo heading if I am accessing it through the webview in our React Native wrapper app. When I select it, the web inspector window does appear.
However, once it opens, the Elements pane is empty, the Console pane is empty, expressions entered into the console are not evaluated, there's no content in Sources, Network, Storage, etc.
Important notes:
This broken state happens at http://localhost:8088 as well as http://127.0.0.1:8088, and it seems that the insecure context is the issue.
The web inspector DOES work for HTTPS sites. If I navigate to, e.g., https://example.com in the simulator and connect the web inspector, everything works fine.
The web inspector also works fine in Safari on macOS (OUTSIDE the simulator) when accessing non-HTTPS sites. It's only a problem for non-HTTPS sites when connecting to the simulator.
A coworker has the same problem, so it is not isolated to my machine.
I would enable TLS locally as a workaround, but this web app is very complex, and I know from experience that it is very difficult for various reasons to set it up properly for our project in development, and it will take significant non-trivial work to do so.
So... Why is this happening? Is this expected behavior? Is there a way that I can debug my site on localhost without HTTPS?

It's being a very long time that I discovery that in some web pages, that use function requestAnimationFrame will cause a lot of cpu, but very little in Chrome. I have already submitted this bug nearly two years ago without printout requestAnimationFrame, no one replied. I submitted again and mention requestAnimationFrame recently, hope there will be some response. If anyone interested in this issue and know some tech in javascript please help. You can enter https://www.baidu.com/ and click one of the topic in all the 百度热搜 which have 弹幕滚动(using requestAnimationFrame, and cause a lot of cpu usage) on right.
Hello All,
On our iOS app, we plan to show tutorial (WKWebview) only in case user has safari extension disabled.
How can iOS app know about status of Safari extension.
Thanks,
Anup
I am developing an SSO Extension so that I can have SSO with Keycloak across applications.
OIDC/OAuth2 works very well.
But I am struggling with SAML. It works, but it seems that the form submission is always triggered twice.
I use decisionHandler(.cancel) to stop the form submission and redirect it to the browser. I still get the form submitted both by the extension and by the browser.
At some point I tried to allow the form submission in the Extension so that I get the redirect with the response to the browser. It still triggered another submission.
Does anyone experience this issue?
Ever since the iOS and iPadOS 26.2 beta I can’t open Safari at all. Safari tries to open but crashes and goes back to my home screen. I’ve restored my devices and restarted everything and the same issue occurs. I didn’t have this problem on the beta 26.1 but this whole thing started on 26.2.
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.

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?
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.

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;
}
I have a Safari Extension which replaces default new tab and puts a link on a generated new tab.
This link can be either usual URL link, or a URL Scheme, something like
plecoapi://x-callback-url/df?hw=${char}&sec=dict
In iOS 17 and previosly, this link worked flawlessly.
In iOS 18, including 18.2, this X-Callback-URL link works only once, if I kill Safari process, reopen Safari and tap the link.
Each subsequent tap will just reload the page, link won't work anymore until the next Safari reload.
Usual URL links works every time without a problem.
Hello,
Recently, there is an issue in my service that after typing korean at input element, first click event is not working.
But i knew that other services are also having same problem.
It happens only on Safari.
Could you guys check this issue?
Thank you.
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 have a Safari extension that plays audio via the javascript AudioContext API. It was working fine under iOS 17 and is now broken under iOS 18. It does not play audio at all.
I've tried in both the iOS 18 public beta and the iOS 18.1 developer beta. It is broken in both of them.
I've also created Feedback item FB15170620 which has a url attached to a page I created which demonstrates the issue.
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?
I'm looking for answer or documentation on gatekeeper and launching a MacOS app via a url scheme/custom protocol.
Our application is delivered via a zip file downloaded from the web. We utilize a url scheme. The act of extracting the app from the zip registers the url scheme with the OS.
From previous research/testing we found we had to break the gatekeeper lock (have the user move the app from the downloaded location) to ensure that the url is honored on first launch of the application. To ensure user compliance, we added a check to make sure that the lock has been removed by looking at the quarantine attribute.
This flow is not ideal. I am looking for alternatives and was previously under the impression that if we were to move to a DMG then that would provide the user a better user experience for moving it. However, now that I am getting
around to looking into it, I am seeing some implied statements that this is not the case and that the quarantine bit will just be moved from the DMG to the app.
Questions:
Does a DMG allow the app to be launched via custom protocol without prior launch or movement?
With a notarized app, will the custom protocol work on a subsequent launch, even without prior movement?

I've been developing a Safari web extension for MacOS and iOS, and I'm running into a very strange issue.
I ported over my Chrome extension to Safari, and for several days as I was iterating on the extension (change code, build, run, test in Safari), everything worked perfectly fine.
Once I was finished with the extension, I followed the instructions on how to prepare to submit the Safari web extension (and it's containing MacOS and iOS apps) to the App Store for review.
For the MacOS app and Safari web extension on Mac, I changed my target from "My Mac" (which I'd been using for testing), to "Any Mac". I then went to the "Product" menu in Xcode and selected "Archive"
That's when things started to go wrong.
The next time I went to Safari, my web extension could no longer find critical files to run the extension (such as background.js, popup.html, etc.) This was despite there being no code changes before or after me creating a build archive.
When I restarted Safari, the extension no longer appeared in the list of extensions within preferences. No matter what I do (clean build folder and re-run, restart Safari, restart Xcode, restart computer), nothing will get my extension to show up in Safari again.
Note that this does not happen with the Safari web extension in the iOS simulator. It only happens on Mac.
I was confident that my extension was working, so I submitted my extension to the Mac App Store for review. It was approved, and a few users have downloaded it and it works totally fine.
To further try to figure out what's going on, I created a new sample Xcode project. From the new project screen, I chose the "Safari web extension" under "Multiplatform".
Without making any code changes, I build and run that project, and the default MacOS app and Safari web extension from the template. I then immediately create an archive (with no code changes). Once I try to run the project for my Mac again, the extension no longer works.
So I have verified that this problem does not have to do with my extension's code, but I cannot for the life of me figure out what is wrong. I have examined every possible build setting, but given that I ran a default project template, made no changes, and it still had this problem, I'm not sure what else could be wrong.
TLDR: I’m searching for a possibility to allow the usage of passkeys and hardware keys for any website in a wkwebview
INFO: The browser is macOS ONLY
Hi, I couldn’t really find documentation or forums posts on how to implement Webauthn for signin or hardware security keys for a second factor. Or rather where those events are triggered to be handled. In Safari you have that popover, that lets you either authenticate through Passwords or with a security key.
When I visit webauthn.io for testing and click either register or authenticate I get
Told not to present authorization sheet: Error Domain=com.apple.AuthenticationServicesCore.AuthorizationError Code=1 "(null)"
ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)"
If I add
func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping @MainActor (URLSession.AuthChallengeDisposition, URLCredential?) -> Void)
and
func webView(_ webView: WKWebView, authenticationChallenge challenge: URLAuthenticationChallenge, shouldAllowDeprecatedTLS decisionHandler: @escaping @MainActor (Bool) -> Void)
it doesn’t seem to change anything.
I found something about the ASWebAuthenticationSessionWebBrowserSupported entitlement, but by my understanding this is used so a browser can get opened upon some other app calling a ASWebAuthenticationSession.
Has anyone some guidance for me? I feel like webauthn and yubikey support are important security measures for our users.

Our service includes the Apple web login feature to support "Sign in with Apple" on iOS 12.
However, at some point, an error started occurring on the Apple login page in iOS 12, preventing users from proceeding further.
Upon checking the Web Inspector console, we found the following error:
Failed to load resource: the server responded with a status of 503 (Service Temporarily Unavailable)
Please help us resolve this issue so that users can continue using "Sign in with Apple" on iOS 12.
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?
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!
