WKWebView has a new property "isBlockedByScreenTime" since iOS 26. But I do not yet understand when exactly this property could be used.
When I setup content-based restrictions in the ScreenTime settings then WKWebView reports an error 105 via "webView:didFailProvisionalNavigation:" delegate. The isBlockedByScreenTime property still returns false in this case.
If ScreenTime has a time-based limit, the App would not run at all.
Under which circumstances would the property "isBlockedByScreenTime" return the value true? When exactly and for what can this property be actually used?
The "problem" is that I want to find if a web page is blocked and can not be loaded, why this is the case. By simply trial and error I found out that WKWebView returns error codes 104 and 105 for blocked web sites because of content filters and Screen Time restrictions, however these error codes are not documented at all (at least I've not found any documentation or documentation for these error codes and also some other codes like 100, 102, 204 etc), so I'm not really sure if I handle all cases correctly.
I hoped that isBlockedByScreenTime would at least tell me one reason for blocked pages.
If there are documents which explain these error codes (100 and above), where I can find these?

在 iOS 平台使用 WKWebView 通过file://协议加载本地 HTML 文件时,存储在localStorage中的数据会在 App 后台切换、进程重启后偶尔丢失;但相同代码在安卓 / 鸿蒙平台无此问题。
现在的文档
仅明确了「默认数据存储(defaultDataStore)可将网站数据持久化到磁盘,非持久化存储(nonPersistent)仅存内存」的基础规则;
未提及「file://协议内容即使使用默认持久化存储,也会被归为临时内存存储」这一关键场景限制;
仅在WKURLSchemeHandler关联说明中隐含「自定义 URL 协议可处理 WebKit 原生不支持的 URL 方案」,但未直接关联file://的存储问题。
我找不到如何处理这个问题的官方文档,仅仅有其他的博客说需要增加http/https加载就没有这个问题。
请提供给我官方文档或者官方回复 关于出现这种file:/加载html出现问题的处理办法
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
This is my first post, so please forgive me if it is to the wrong area.
I've been using Tahoe for a few days and, overall, it's very stable. But the one thing that has bothered me to no end is Safari's new behavior with respect to its header (Address bar, Favorite bookmarks bar, tab bar) background color. The web content of the active tab seems to affect everything - and oftentimes makes things completely unreadable - at least in "Dark" mode. For instance, if a web page uses a white background, the Favorites bookmark labels are the same color as the bookmark background, so reading the labels is simply impossible. At other times, they're just very difficult to read.
Similarly, it is almost always impossible to tell which tab is the active one - my only workaround is to try 100% brightness....or to just guess.
When Apple previously experimented with letting content bleed through to the top, there was a setting for stopping it - but I don't see such a setting anymore. Do you you know of any way to stop this effect?
"The Referer header allows a server to identify referring pages that people are visiting from or where requested resources are being used. "
This header is never forwarded to server when the user is browsing the website in a WebView. This is properly maintained by other browsers but not in-app.
How do I include it?

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.
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
How to allocate the width of each column when customizing the rendering of HTML tables on iOS with limited screen width

The new WebView implementation in *OS 26 versions is a very valuable addition to the SwiftUI toolset. I was experimenting with it and was wondering how to implement a Pull To Refresh. While this was easily achievable with the "old" WKWebView I was not able to find an API to implement, for example, a page reload when the user uses a pull to refresh gesture.
I tried to attach to a .refreshable(_:) modifier to the WebView but without success.
Is there an official API for that or should maybe .refreshable(_:) already work and it's just a bug or is it simply not yet supported?
Here is a minimal example I was trying but didn't succeed:
struct ContentView: View {
@State private var page = WebPage()
var body: some View {
NavigationStack {
WebView(page)
.refreshable {
page.reload()
}
}
}
}
Any help is much appreciated. Thank you!
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:

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?
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 have a content blocker that generally works correctly, but I need to block an element that has certain text in it.
For example, <span id="theId">Some text</span> is easy enough to block because I can locate the id and block that, but what if there is no id, or the id is completely random? What if it's just <span>Some text</span>? How do I block that?
Let's say this is my only content blocker rule:
[
{
"action": {
"type": "css-display-none",
"selector": ":has-text(/Some text/i)"
},
"trigger": {
"url-filter": ".*"
}
}
]
No errors are seen when the rule is loaded, so it's syntactically correct, it just doesn't block the HTML. I gather this is because :has-text() works on attributes, not contents, so it works on alt, href, aria-label etc. but not on the contents of the element itself.
How do I block Some text in my example above? Thanks!
I reported this bug one year ago in https://developer.apple.com/forums/thread/746406, but as it is not been fixed yet, I'm going to try by opening this new incident report.
iOS is not working for the Unicode Variation Selector-15 (U+FE0E) for all the characters.
Can you please apply that variation selector to all your Unicode characters?
I) Steps to reproduce the issue:
navigate in safari to the page https://eurovot.com/vs.htm
II) Expected result:
as the 1st column of characters have the Variation Selector-15 (U+FE0E) applied, and the 2nd column have the Variation Selector-16 (U+FE0F) applied, the first column should always display text characters (in orange) and the second column emoji characters.
III) Error result:
some characters are working fine in the 1st column and displayed as text (in orange colour), but some other aren't displayed as text, they wrongly displayed as emojis instead.

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.
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?
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?

We have a JavaScript api that queries our Secure Browser to get the network information – signal strength, network name, plugged in/wifi. Everything worked fine through the Tahoe betas, still does. Now we are getting on the network name and this is breaking our UI. Was this an intentional change or a bug? The other two properties still appear to be working. And it works in all lower MacOS versions.
We are currently obtaining it through AppleScript
try
set ssid to do shell script "system_profiler SPAirPortDataType | awk '/Current Network Information:/ {getline; sub(/^ +/, ""); sub(/:$/, ""); print}'"
if ssid is equal to "" then
return "Not connected to any Wi-Fi network."
else
return ssid
end if
on error errMsg
return "Error: " & errMsg
end try

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.

We’re encountering an issue when trying to add non-standard headers to outgoing requests using Declarative Net Request (DNR) rules in our Safari Web Extension.
Tested on macOS 15.4 with Safari 18.4.
Specifically, when attempting to add a custom header such as "X-Custom-Header" using a DNR rule, the header does not appear in the request. We are able to add standard headers like "Authorization" and "Cookie" to the request successfully using the same method.
This behavior suggests that Safari may be filtering or blocking non-standard headers when set via DNR rules, unlike other browsers.
In Chrome and Firefox, the same rule adds the "X-Custom-Header" header without any issue.
We are looking for assistance in fixing these issues and having our Safari Extension function the same as it does in Firefox and Chrome.
