Hello,
I'm not able to get the webauthn attestation statement using the option (attestation.direct) on Safari. The answer I get is a fmt of none and a aaguid of zeros.
The same code works on Chrome and I was able to get a none zero aaguid and a packed fmt attestation.
Can you explain why this does not work on Safari ?
Thank you.

Is this symbol, which Safari uses to the left of the address bar, in the public SF Symbols set? What's it called?
I'm encountering an issue with front camera video recordings via browser (Safari/Chrome) on devices running iOS/iPadOS 18 and above:
On iPad, the recorded video appears upside down.
On iPhone, the recorded video is rotated 90 degrees.
The rear camera functions correctly without orientation issues.
This problem seems specific to browser-based recordings, as the native Camera app records videos with the correct orientation.
Has anyone else experienced this behavior? Is there a known workaround or fix?
The preview while recording is fine, the recorded video is oriented incorrectly.
I'm trying to sync authentication data from my iOS app to a Safari Web Extension using App Groups, but the extension isn't consistently receiving the data.
Setup:
App Group: group.com.airaai.AiraApp (configured in both app and extension)
iOS app writes auth data using UserDefaults(suiteName: "group.com.airaai.AiraApp")
Extension's Swift SafariWebExtensionHandler reads from App Groups in beginRequest()
Extension's JavaScript reads from browser.storage.local
Problem:
Extension popup always shows "logged out" even when:
User is logged into main iOS app
Auth data exists in App Groups (verified via native module logs)
Handler successfully writes test values to extension storage
Current Behavior:
Handler CAN read from App Groups ✅
Handler CAN write test values to extension storage ✅
But auth data doesn't appear in browser.storage.local when popup checks ❌
Popup reads empty keys even though handler logged writing them
Code:
// Handler reads from App Groups
guard let sharedDefaults = UserDefaults(suiteName: "groupName") else { return }
let authData = sharedDefaults.string(forKey: "auth_data")
// Handler writes to extension storage (tried multiple suite names)
let extensionDefaults = UserDefaults(suiteName: Bundle.main.bundleIdentifier ?? "")
extensionDefaults?.set(authData, forKey: "oauth_token")
extensionDefaults?.synchronize()
// Popup reads from storage
browser.storage.local.get(['oauth_token']).then(data => {
console.log(data); // Always empty {}
});
What I've tried:
✅ App Groups properly configured in both targets
✅ Extension has App Groups capability enabled
✅ Multiple UserDefaults suite names (bundle ID, bundle ID + suffix)
✅ Delayed sync attempts in handler
✅ Comprehensive logging
Questions:
What is the correct UserDefaults suite name for Safari extension storage on iOS?
When does beginRequest() get called? Can it be triggered manually?
Is App Groups the right approach, or should I use a different pattern?
Alternatives I've considered:
Deep link/redirect method (app opens Safari with token in URL)
Content script intercepts URL and sends to background script
Is this a supported approach for iOS Safari extensions?
Any guidance or examples would be greatly appreciated!
Hi,
we have PWA for which we´ve built a wrapper using PWA Builder tool and we are experiencing an issue with apple sign in.
When we try to redirect the user to "https://appleid.apple.com/auth/authorize?...params...", a bottom sheet login prompt appears and only once the user signs in using the prompt he is then redirected to the url where he needs to sign in again and then we get the callback. We want to get rid of that bottom sheet prompt.
The code we´ve tried:
` iosButton.addEventListener('click', function () {
window.location.href = "https://appleid.apple.com/auth/authorize?client_id=xxxxx&redirect_uri=xxxxx&response_type=code%20id_token&scope=name%20email&response_mode=form_post";
});`
The alternative code we´ve tried for which it seems that nothing happens, we only see the "Started" alert, we´ve confirmed that there is no other error :
` <script src="https://appleid.cdn-apple.com/appleauth/static/jsapi/appleid/1/en_US/appleid.auth.js"></script>
<script>
(function initAppleSignIn() {
try {
window.AppleID.auth.init({
clientId: "{{ env('APPLE_WEB_CLIENT_ID') }}",
scope: "name email",
redirectURI: window.location.origin +"/auth/apple/callback",
usePopup: true
});
} catch (e) {
console.warn('Apple Sign-In init skipped:', e);
}
})();
function appleButtonClicked() {
alert("Started");
try {
const res = await window.AppleID.auth.signIn();
} catch (err) {
alert("Got error");
}
alert("Got here");
}
</script>
After updating to the new iOS, in Safari, my overlays and backdrops using 100dvh no longer cover the full screen there's now a gap at the bottom.
Switching to 100vh fixes it, but that causes scrolling issues on older Safari versions since 100vh includes extra height.
Has anyone else experienced this? What's the recommended fix that works across iOS versions?
Create shortcut to open chrome with url and put it on the desktop.
Tap the shortcut.
Tap the username text field.
When launching Safari from an iOS shortcut on an iOS device with a valid passkey registered, the passkey suggestion does not appear; instead, the password suggestion appears sometimes.

Hi,
I am developing an OpenType font with the following cursive feature.
feature curs {
lookup cursivejoinrtl; # RIGHT_TO_LEFT flag set between Hah, Meem, Yeh and final Meem
lookup rehwawcursive; # RIGHT_TO_LEFT flag clear between Waw and Hah
} curs;
Here is the rendering of the word وحميم in TextEdit.
Using HarfBuzz I got the following result.
The same rendering problem occurs when using Safari. It seems that is related to Core Text.
I reported the issue to Feedback Assistant over a year ago but haven't had a response yet. So I'm posting the problem on this forum.
Any support on this matter would be greatly appreciated.
Based on the "Build immersive web experiences with WebXR"-Video for visionOS there is no way to disable the consent prompts for entering an immersive experience or consent hand-tracking. For the microphone it's possible to "greenlight" specific websites for mic input, which works great.
I'd welcome it, if it were possible to add specific websites in the settings, in which those consent dialogs aren't shown each time.
In my opinion, the user interaction through a button that launches the experience would be sufficient to not disorient.
Hello
We've encountered an issue with WKWebView in the latest iOS 26 beta. When loading a PDF URL, the background of the PDF viewer now displays as a dark gray instead of the expected white.
Device: iOS 26 Simulator/Device
Component: WKWebView
Issue: The background color of the loaded PDF is gray.
Expected Behavior: The background should be white, as it has been in all previous iOS versions.
Link for Testing: https://help.apple.com/pdf/security/en_US/apple-platform-security-guide.pdf
We confirmed that the same PDF and code render with a white background on iOS 26 and earlier.
Questions:
Is this an intentional change in iOS 26's WKWebView?
If so, is there a new property or configuration setting available to control the background color of the PDF viewer within WKWebView? We would like to have the ability to set it back to white.
Any insights, workarounds, or information on this matter would be greatly appreciated.
Thank you.
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
I’m developing a Safari App Extension and I want to debug the background.js script.
However, I can’t find any tool or option to do this.
When I run the extension from Xcode using the ProjectName Extension (macOS) scheme, I expect to see a “ProjectName” item under the Develop → Web Extension Background Content menu.
But there’s nothing there.
Has anyone encountered the same issue? How did you fix it?
Environment:
Manifest Version: V3
Safari: 26.0.1 (21622.1.22.11.15)
Xcode: 26.0.1 (17A400)
In WKWebView, there is the WKUIDelegate method:
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {}
This delegate method provides a callback when a new window (for example, target="_blank") is requested in the web view.
However, in native SwiftUI (iOS 26), WebView / WebPage APIs do not provide an equivalent delegate method to handle new window requests.
As a workaround, I am using the following method:
public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy {}
In this method, when action.target == nil, I treat it as a new window request.
My question:
Is relying on action.target == nil in decidePolicy a reliable and future-safe way to detect new window requests in SwiftUI’s WebView, or is there a better or more recommended approach for handling target="_blank" / new window navigation in the SwiftUI WebView APIs?
Code:
public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy {
guard let webPage = webPage else { return .cancel }
// Handle case where target frame is nil (e.g., target="_blank" or window.open)
// This indicates a new window request
if action.target == nil {
print("Target frame is nil - new window requested")
// WORKAROUND: Until iOS 26 WebPage UI protocol is available, we handle new windows here
// Try to create a new WebPage through UI plugins
if handleCreateWebPage(for: webPage, navigationAction: action) != nil {
// Note: The new WebPage has been created and published to the view
return .allow
}
}
return .allow
}
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.
Hi,
I have an app that uses WKWebView and it's crashing on iOS 26 Simulator in places I've never had problems before. In this case it's crashing when calling WKWebView.callAsyncJavaScript, but in my other project WKWebView is crashing with some sort of EXC_BAD_ACCESS other than callAsyncJavaScript.
Am I missing something?
Thanks,

Since Xcode 26 our tests are crashing due to the Main Thread not being able to deallocate WKNavigationResponse.
Following an example:
import Foundation
import WebKit
final class WKNavigationResponeMock: WKNavigationResponse {
private let urlResponse: URLResponse
override var response: URLResponse { urlResponse }
init(urlResponse: URLResponse) {
self.urlResponse = urlResponse
super.init()
}
convenience init(httpUrlResponse: HTTPURLResponse) {
self.init(urlResponse: httpUrlResponse)
}
convenience init?(url: URL, statusCode: Int) {
guard let httpURLResponse = HTTPURLResponse(url: url, statusCode: statusCode, httpVersion: nil, headerFields: nil) else {
return nil
}
self.init(httpUrlResponse: httpURLResponse)
}
}
import WebKit
import XCTest
final class ExampleTests: XCTestCase {
@MainActor func testAllocAndDeallocWKNavigationResponse() {
let expectedURL = URL(string: "https://galaxus.ch/")!
let expectedStatusCode = 404
let instance = WKNavigationResponeMock()
// here it should dealloc/deinit `instance` automatically
}
Here the call stack:
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread
0 CoreFoundation 0x101f3dd54 CFRetain.cold.1 + 16
1 CoreFoundation 0x101e14860 CFRetain + 104

YouTube now requires a Referer to be sent to be able to embed Youtube videos, otherwise the videos won't work. But WKWebView doesn't send a Referer when using a custom scheme, so Youtube videos stopped working in that case.
This affects Ionic apps, both using Cordova or Capacitor. There's an open issue for Cordova and another one for Capacitor. In these apps, the app is served using a custom scheme like capacitor://localhost or ionic://localhost.
I tried modifying the Ionic WebView source code to force adding a referrer to the URL loaded using WKWebView's loadRequest:
[request addValue:@"https://my.test.app" forHTTPHeaderField:@"Referer"];
[_engineWebView loadRequest:request]
But the Referer is still not sent in the Requests, I guess because the app is using a custom scheme (e.g. capacitor://localhost). However, if I modify this code to force loading an "online URL" (using https) instead of capacitor://localhost, then the my.test.app Referer is sent to the requests.
Is there any way to make WKWebView send a Referer when using a custom scheme?
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?
We’re seeing an issue in our Safari Web Extension where not all cookies from the Set-Cookie response header are accessible. We are using macOS 15.4 and Safari 18.4.
In the webRequest.onHeadersReceived callback, the Set-Cookie header returned by Safari only includes some of the cookies set by the server. If multiple Set-Cookie headers are present, we seem to receive only a partial list, some cookies are missing entirely.
In Chrome and Firefox, the same callback provides all cookies set by the server without 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.
We have a SAML-based SSO App Extension that uses WKWebView to load the SAML login request. This implementation has been working correctly on iOS versions prior to 26. However, starting with iOS 26, the extension consistently crashes when calling WKWebView.load(_:).
The crash occurs inside WebKit, specifically in:
/Library/Caches/com.apple.xbs/Sources/WebKit/Source/WebKit/UIProcess/WebsiteData/WebsiteDataStore.cpp
at
WebKit::WebPageProxy::loadRequest(...)
No app-level exception is thrown, and the extension terminates with:
Thread 10: EXC_BREAKPOINT (code=1, subcode=0x1a31dbe00)
It appears that WKWebView initialization or WebsiteDataStore creation is now restricted in extension contexts on iOS 26, but this change is not documented in the SDK release notes. Could you please confirm if this is an intentional sandbox restriction in iOS 26 or a regression in WebKit?
Steps to reproduce:
Implement an App Extension using ASAuthorizationProviderExtensionAuthorizationRequest.
Create a WKWebView instance in the extension.
Attempt to load a SAML login request (POST request with headers).
Observe immediate crash on iOS 26 (works fine on earlier versions).
Expected behavior:
WKWebView should load the request or fail gracefully as in prior releases, without crashing the extension process.
Request:
Please clarify if WKWebView usage inside extensions is officially unsupported as of iOS 26, and if so, recommend an alternative approach for handling SSO flows.
