I'm developing an application that makes use of a WebView. When resuming the app I occasionally run into an issue where the application just shows as a blank page. In the Console.app I see a stack trace, however the details are hidden (see below).
The stack trace is thrown from JavaScriptCore.

Hello, ive been dealing with this glitch all year that hasnt happened last year. When I watch a video on public safari and then it exit the video it immediately takes me to the private tab but when I go on the private tab to watch videos and exit out it takes me back to the website just like normal. Its a pretty annoying bug and I watch all my videos in the private tab because of it

This is a really strange issue on iOS Safari. Under certain conditions a basic input element will not be focusable or show the on screen keyboard. I can reproduce the issue with a very simple HTML file by dynamically adding an anchor element with an href during a touch event. If you add a different element or an anchor without an href, there is no issue. Similarly, if you apply the same listener to a click event there is no issue.
Reproducible in iOS Simulator 17.2 and 18.1
This HTML/JS showcases the problem:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>InputIssue</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<div id="parent">
<input type="text" name="test" />
<div id="child"></div>
</div>
<script>
document.addEventListener("touchstart", () => {
const child = document.getElementById("child");
if (!child) return;
while (child.firstChild) {
child.removeChild(child.firstChild);
}
const link = document.createElement("a");
link.href = "https://test.com";
link.textContent = "test";
child.appendChild(link);
});
</script>
</body>

Hey team, I've integrated custom WkWebsiteDatastore to manage profiling for different sessions.
upon testing the WkWebsiteDataStore as its mentioned to be persistent But
The storage can be accessed via identifier, But the session data in storage is absent, such as cookies caches all are cleared when app is relaunched
is it the default behavior to be expected or there is some property missing causing the session data to be removed from storage.

Hi! I'm trying to implement ASWebAuthenticationSession to log in to my app via the web app backend. However, I'm a bit confused about the cookies that this has access to. When I set prefersEphemeralWebBrowserSession=false it does not seem to use the cookies from Safari. Or at least, I'm logged into my web app in Safari, but when I use ASWebAuthenticationSession I still have to log in again. Does it not share session cookies with Safari?
I did notice that if I don't use an ephemeral session, once I log out and try to log back in my app does automatically log me in but that's actually unhelpful in my opinion because now I have no way to clear that session because it only lives in the ASWebAuthenticationSession context. If that's the case I may as well use the ephemeral session then because it seems to have only drawbacks.
We have a Safari extension that's been up on the App Store for about 18 months with no apparent issues. This week, however, while working on an update, we uninstalled the production version on our test machines and installed a developer version. When we had some issues, we tried to go back to the production version downloaded from the App Store, but we get an pop saying "Unable to download App." In the log, the most obviously relevant error is 'Operation not permitted'.
This occurs on several machines and different logins on those machines in both norma and safe modes. However, on another machine that never had one installed, we could still install the app from the app store, so I suspect there is something left behind that needs to be removed, but I don't know what.
FWIW, I see the download directory getting created under /Applications, but it is promptly removed when the failure popup appears.
Any suggestions?
I have a Safari Web Extension that successfully receives a message from a webpage and returns a response.
I now want to add a user interface to the Safari Web Extension. How do I do this?
I have modified the default template code as follow to add an NSAlert for testing. The modal runs, but no alert ever appears, and the code remains stuck at runModal.
What is the correct way to add a UI to a webextension?
- (void)beginRequestWithExtensionContext:(NSExtensionContext *)context {
id message = [context.inputItems.firstObject userInfo][SFExtensionMessageKey];
NSLog(@"Received message from browser.runtime.sendNativeMessage: %@", message);
NSAlert* alert = [[NSAlert alloc]init];
[alert setMessageText:message[@"request"]];
[alert setInformativeText:@"Hello"];
[alert runModal];
NSExtensionItem *response = [[NSExtensionItem alloc] init];
response.userInfo = @{ SFExtensionMessageKey: @{ @"id": message[@"id"], @"uuid": message[@"uuid"], @"contentType": message[@"contentType"], @"response": message[@"request"] } };
[context completeRequestReturningItems:@[ response ] completionHandler:nil];
}
@end
What happens if Safari is uninstalled or disabled on iOS?
Will SFafariviewcontroller still work?
Kind regards
After reading several posts I see that I need to add the "com.apple.developer.web-browser.public-key-credential" capability to my macOS app in order to get it to work.
So my noob question is where do I request this capability? Can I as a developer request it or does the Account owner need to request it?
Once approved, how do I add it to my app's capabilities?
Thanks for your patience
I have a local HTML file used to display mixed content with images and text. Here's the issue: the same file displays everything correctly in Google Chrome, showing both images and text as expected. However, when opened in Safari, only the text is shown—images are missing, which is very strange.
Interestingly, if I remove .png from the title attribute of the tag, the images show up properly in Safari. Alternatively, if I comment out the inclusion of html2canvas.min.js, the images also display correctly (although the layout breaks without it).
I'm not sure if this is a Safari-specific issue. Can anyone explain what might be causing this problem?

We're embedding the Power BI reports into our portal by using JS library. While testing them, we found that mobile layout of the reports don't work as we expect on iOS devices (tested in Chrome and Safari). There are two principals issues: 1) the site is automatically refreshed when the users filter the data (we reduced them to lower expression) and 2) the site also crashes after a while using the dashboard by applying different filters.
Hi,
I’m working with the SFExtensionProfileKey in my Safari Web Extension. As I understand it, this key is to get the UUID of the profile currently in use. However, it seems to be missing (no key in userInfo) when the default profile is active. Also, I haven’t found any API to get a profile’s human-readable name or list all available profiles.
Could someone clarify:
If the value of SFExtensionProfileKey is absent, can I safely assume the default profile is in use?
Is there a supported way to get a profile’s display name?
Does Safari expose an API for getting all profiles?
Thanks in advance for your insights!

• 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 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.

This is the code suggested by Grok 3 Beta, but I see this error:

Hello,
I am developing a website which starts a web worker using the js code:
const zarrWorker = new Worker('./zarr_file.js', { type: 'module' });.
The script 'zarr_file.js' is served from the same origin with Cross-Origin-Embedder-Policy: require-corp and Cross-Origin-Opener-Policy: same-origin and it is importing external modules through the import statement (e.g. import * as zarr from "https://cdn.jsdelivr.net/npm/zarrita/+esm";).
All the external modules are blocked by Safari with the error Worker load was blocked by Cross-Origin-Embedder-Policy, although I can see (by running curl on them) that they correctly set cross-origin-resource-policy: cross-origin`.
The same website works fine in Chrome and Firefox.
Is it a bug or is Safari implementing stricter policies? In the latter case what would be the solution?
I have a UI application built with the Vue framework, using Vuetify for the UI components. There's a div with the class v-application--wrap, which is provided by Vuetify. This class internally includes the following style rule.
.v-application--wrap {
backface-visibility: hidden;
display: flex;
flex: 1 1 auto;
flex-direction: column;
max-width: 100%;
min-height: 100vh;
position: relative;
}
The pages were rendering correctly up to version 18.3, but after upgrading to version 18.4, we encountered layout issues related to height. Upon investigation, we discovered that the min-height property was no longer being interpreted or applied correctly. Replacing min-height with height resolved the issue, and the pages began loading as expected.
Any insights into why this behavior is occurring would be greatly appreciated.
