It seems Safari 18's fetch() does not include credentials even credentials: include and safari extension has host_permissions for that domain.
Is there anyone has this problem?
I try to request in popup.js like this:
const response = await fetch(
url,
{
method: 'GET',
mode: 'cors',
credentials: 'include',
referrerPolicy: 'no-referrer',
}
);
and it does not include the cookie from host_permissions.
Those code worked in Safari 17 (macOS Sonoma).

iOS 18 WKWebView images are not loading, no errors in older versions.
The example while loading HTML is as follows. A problem occurs when you pull an image from a url. To get a URL image you need a cookie or something. I add them too, but it doesn't work on iOS 18. I get the error "An error occurred trying to load the resource." and a blue question mark on the screen.
webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)

I have an issue with web ads not working in Safari versions earlier than 16.4.
While debugging Safari Web Ads I found out that I don't get postbacks from versions 16.4 or below from Safari, although there are no technical limitations and the documentation says that web ads should work starting from versions 16.1 https://developer.apple.com/documentation/storekit/skadnetwork/skadnetwork_release_notes/skadnetwork_4_release_notes
For ads that appear in an app, the app is built with iOS 16.1 SDK or later. For web ads, the ad appears in Safari 16.1 or later.``
Maybe I missed something and Apple didn't update the documentation, is that normal?
Maybe it's related to this release and there was a technical problem with Apple? https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-16_4-release-notes/#SKAdNetwork
Has anyone encountered the same problem and how did you fix it?
Thanks!
So recently Intune add support for controlling safari web extension enablement using the new ddm configuration added in Macos 15, but unfortunately I can't make it work no matter what I try.
On the destination machine I see the that a user declaration for safari extension has been created, but there is not details on which extension they applied and it seems faulty (See attachment)
I have 2 questions:
Has anyone managed to make it work?
Is there a way to test this declaration like I can do with Mobile config by manually load it to the machine?
Thank you.
My Safari extension has a WKWebView in the main app and an HTML popup window in Safari. For some reason, both are in dark mode on visionOS, even though the device environment is light and Safari tabs are also showing light mode. Why does this happen, and how can I change it?
Hi, there.
I am trying to use ServiceWorker on iPad to retry a request that has a communication error. However, I am having trouble with the process being terminated after 70 seconds.
Occurs at least on iPadOS 17.6.1 and 16.3.
The following is the service worker code to reproduce the problem:
self.addEventListener('fetch', (event) => {
if (event.request.url.includes('test.html')) {
event.respondWith(longRunFetch());
}
});
async function longRunFetch(request) {
await new Promise(resolve => setTimeout(resolve, 75000));
return new Response('Fetch completed');
}
When this code is executed on an iPad and a request is made to test.html, the service worker stops after about 70 seconds. When it stops, it falls back to the network request and the contents of test.html are displayed. The service worker thread appears to be killed and is unavailable until the browser is restarted.
If timeout is set to 65000, 'Fetch completed' is displayed as expected.
Why is the process terminated in 70 seconds?
Is there any way to continue processing beyond 70 seconds?
Hi, I am having issue with WebAssembly not able to load wasm file on Safari web extension.
It is showing CompileError: Refused to create a WebAssembly object because 'unsafe-eval' or 'wasm-unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'wasm-unsafe-eval'".
It was working fine 2 month ago, my original CPS is "script-src 'self' 'unsafe-eval'". But now it is not accepting 'unsafe-eval', I also tried 'wasm-unsafe-eval' did not work.
Is there any changes on Safari browser regarding the CSP for WebAssenbly? Please let me know what CPS value will work.
Here is the example code on how I load the WebAssembly wasm file.
fetch('test_wasm_lib.wasm')
.then(response => {
if (!response.ok) throw new Error('Network response was not ok');
return response.arrayBuffer();
})
.then(bytes => WebAssembly.instantiate(bytes))
.then(results => {
// Use your WebAssembly instance here
console.log('load wasm success')
})
.catch(error => {
console.error('Error loading WASM:', error);
});
We are using manifest version 2, and currently some dynamic ads which come under the #document (documentURL) are not getting fetched and we are not able to block.
is there an alternative for onBeginRequest in iOS Safari? How can we fetch the dynamic URLs otherwise?
Is it possible to enable/disable the enabled flag before the extension is loaded? we want to have a button in our app which controls the availability of the content blocker ruleSet in declarative_net_request in manifest (version 2).
"declarative_net_request": {
"rule_resources": [
{
"id": "ruleset_1",
"enabled": true,
"path": "ruleset_1.json"
}
]
},
We have observed that blocking content using Safari web extension does not fetch few URLS within the #document (documentURLs) because the onBeforeRequest webextension API is currently not available in Safari iOS.
But it works fine using the Content blocking extension.
We have a list of URLs which we want to block from the website. Which extension would you suggest the Content blocking extension or the Safari web extension?
Hi everyone,
I’m working on an iOS app using WKWebView, and I have a specific use case involving cross-origin iframes and form autofill. I’m wondering if it’s possible to programmatically fill input elements, such as credit card numbers, within a cross-origin iframe loaded in a WKWebView.
I understand that due to the Same-Origin Policy, direct DOM manipulation of cross-origin iframes is restricted. However, I’m curious if there are any methods or workarounds that might allow me to achieve this, specifically within the context of WKWebView. Thanks.

Since updating to iOS v17.4.1 our safari extension no longer functions as it used to
We are experiencing issues where our content script is not getting initialized, On devices running iOS 17.4.1, the content script included in our extension does not appear to run. There are no logs from the content script in the console, whereas on other versions and devices, it operates as expected. Our Extension relies con communication between the background and content scripts in order for us to render various popups to our users, based on our logs as of iOS 17.4.1 this communication is not successful, we can see messages being sent from the background script but as mentioned above nothing on the content script side.
This behavior happens majority of the time and on random sites, sometimes opening the same site in a new tab would work but not always. There are also times where we would only receive our popups after opening the safari menu and interacting with our extension via this menu.
Please assist with a way forward

Flutter web view- I am downloading assets from server and using that assets to create html file to load on web view.
I downloaded them to the local document directory on the device. From there I can load the HTML files in a webview using the file:// schema, with the benefit that images, css etc. that are referenced in the HTML are loaded as well.
This works fine in Android (simulator and real device) as well as in an iOS simulator.
But on an iOS device the flutter webview fails to load assets , images & css files with a relative URL from local directory.
This is strange as the iOS simulator should behave the same in that case (as it is not really a hardware related issue).
Help me out from this issue.
