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.

Hello,
I am currently developing a game streaming application using ReplayKit and Broadcast Upload Extension. I would like to ask for your assistance regarding capturing snapshots of a WKWebView in the upload extension without adding it to a visible view hierarchy.
From my understanding, calling takeSnapshot(with:) on a WKWebView that is not added to the view hierarchy generally works for simple web pages. However, when it comes to more complex web content — such as animations or WebGL — the snapshot returns a blank or static image. I believe this is because rendering such content requires access to the GPU, which is not fully available when the web view is off-screen.
That said, I’ve observed that certain apps are able to capture live animated web content inside their broadcast upload extensions, even when the main app is terminated. This suggests that the snapshot is not being generated by the main app or from a remote server — especially since the network activity confirms the content is served locally (via localhost or local IP).
Given this, I believe there must be a way to achieve GPU-accelerated rendering for WKWebView directly within the upload extension context, without attaching it to the app's UI. I would greatly appreciate any guidance, APIs, or recommended techniques that could help me achieve this behavior correctly and within system limitations.
Thank you in advance for your support. I look forward to your advice.
Warm regards,
I need to know the https address of a certain page within my app. This is going to be used as a redirect URL. I don't think it is a good idea to use deep links because it has to be an https address. I don't think Universal Links will work because it is not my website that I will be communicating with.
Hi Apple Developer Support,
I’m building a macOS app that acts as a default browser. I can confirm that I can set it correctly through System Settings → Default Web Browser.
The app implements ASWebAuthenticationSessionWebBrowserSessionHandling to intercept Single Sign-On (SSO) flows. To handle requests, it presents SSO pages in a WKWebView embedded in a window that this app creates and owns - this works perfectly for the initial login flow.
However, after I close my WebView window and then launch Safari or Chrome, any subsequent SSO requests open in the newly-launched browser instead of my custom browser, even though it remains selected as the default in System Settings.
I’d appreciate any insight on why the system “hands off” to Safari/Chrome in this scenario, and how I can keep my app consistently intercepting all ASWebAuthenticationSession requests.
Here are the steps that break down the issue:
Launch & confirm that the custom default browser app is the default browser in System Settings → Default Web Browser.
Trigger SSO (e.g., try to log in to Slack).
App’s WKWebView appears, and the SSO UI works end-to-end.
Close the WebView window (I have windowShouldClose callback where I cancel the pending session).
Manually launch Safari or Chrome.
Trigger SSO again. Observed behaviour: the login URL opens in Safari/Chrome.
I am using macOS 15.3.2
Actually this is a duplicate for https://developer.apple.com/forums/thread/106537 but in web-specific forums section.
Is there any video/audio codec best practices, guides, recommendations for app/web developers for best performance (take advantage from HW acceleration), power consumption saving? What are officially supported media containers? What are video encoding profiles, video dimensions, frame rates?
The only official source I have found is https://developer.apple.com/documentation/webkit/delivering-video-content-for-safari?language=objc. But h264 is pretty old. I experimentally found that the VP9 video format is also supported on iOS newer versions. But is this a requirement? Сan i be sure that the video will play on all devices?
My goal is to provide web media content (which will be rendered in my application using WKWebView API) that will be supported by most devices (both iOS and MacOS), takes advantage of such features as hardware decode acceleration and be efficient.
Any hints/info is highly appreciated. Best regards.
I have an attachment anchored to the head motion, and I put a WKWebView as the attachment. When I try to interact with the web view, the app crashes with the following errors:

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.

Hi, I'm using a webview in Swift, where I load an html file locally. Basically I have an angular project built and loaded directly into my app bundle. The webview requires the use of the camera. I request permissions via and javascript, the pop-up appears, I accept the permissions and the app works correctly. Only that after a certain number of seconds, the permissions are requested again. It's as if the webview doesn't cache the accepted permissions.
Is this normal behavior?
On iPhone 16 running iOS 18.0(Xcode 16.2), cookies configured with SameSite=None; Secure fail to apply correctly—iOS forcibly converts the attribute to SameSite=Lax. As a result, cross-site requests from H5 pages within our app cannot carry the required cookies, causing failures.
Can anyone help me on this?
Thanks in advance.
myCode is here
// titleScript = "document.querySelector('#\(rawValue) span')?.textContent"
guard let titleResult = try? await webView.evaluateJavaScript(type.titleScript),
let title = titleResult as? String else { return }

Hi all,
I'm developing an application that uses WKWebView to display a web application which I augment with iOS native utilities such as Speech to Text and IAP. The application also uses Service workers, so we define AppBound Domains in the info.plist file.
Everything works for this, but when we deploy on a device the application will crash and say we need these entitlements
com.apple.developer.web-browser-engine.networking,
com.apple.developer.web-browser-engine.rendering,
com.apple.developer.web-browser-engine.webcontent,
com.apple.runningboard.assertions.webkit
From what I can see, we do need all of them. However Apple suggest submitting a request to be an Altnerative Browser (https://developer.apple.com/support/alternative-browser-engines)
This is not appropriate for the application in my view since one requirement of being an alternative browser is that you don't modify the resources on the web site - we of course do since we inject javascript in order to bridge between iOS and the contents of the webview.
How are people navigating this issue? I assumed it would be common given the use of Tauri etc. to build similar types of applications, but I don't see much about it.
Thank you!
Hi Apple Devs & WebKit Team,
We operate https://outdoorgala.com — a verified, HTTPS-secure Canadian ecommerce site focused on elite outdoor safety gear. We're Indigenous-owned, based in Alberta, and take customer trust and compliance seriously.
However, Safari (iOS + macOS) is falsely flagging our site as “deceptive,” preventing customers from accessing us — even though:
We use GoDaddy Website Builder with no redirections or malware
All product links are clean, HTTPS-secure, and tracked ethically
We recently implemented a fully compliant cookie banner (Accept/Decline logic)
A public security.txt and OpenPGP key has been published: https://outdoorgala.com/security
No phishing, malware, or cloaking behavior exists on the site
We’ve already submitted a review via:
➡️ https://websitereview.apple.com
And filed a bug report via Feedback Assistant (FB17608544)
What else can be done to speed up review or get flagged domains unblocked in Safari? This is hurting our business and blocking consumer access — despite following all Apple guidelines.
Would appreciate any insights or escalation tips.
Thank you!

I am trying to record the requests and responses in a WKWebView, but instruments does not seem to record them. Is this to be expected?
The webView is set to inspectable, and I am using the HTTP Traffic instrument.
All the requests the app is doing are recorded, but neither the original request for the webView, nor subsequent traffic is recorded.
When I use Safari to inspect the webView, all I see is the last page (even when I start the inspector before the first request is made).
How can I see these requests?
Dears,
We are facing some issue in ios 18.4.1. Recently some of our end users who updated their ios devices to 18.4.1 have experienced random 403 errors in runtime. as per our analysis, We identified that these errors are associated with "CSRF token mismatch".
After successful login, the user's CSRF token is causing issue and it was changed in runtime, this causes the cookie mismatch, and the users is getting 403 errors, and the user session is getting invalid suddenly.
let me know if anyone facing the same issue in ios 18.4.1 and let me know Is there any workaround for this issue.
Thanks.
Is ServiceWorker supported on WKWebView? As per Mozilla Developer Network(MDN Web) docs[1] its not supported, but our research shows that ServiceWorker becomes available for a domain in WKWebView 1) if the domain is allowlisted in app-bound domains[2] or 2) if app is registered as default browser(this can not be considered for our app as its not a browser).
How to enable ServiceWorker on WKWebView? Is adding domain as app-bound domain the right/only way to enable ServiceWorker on WKWebView? We didn't find any official documentation about this.
Can WebView get ServiceWorker support by default without enabling app bound domains since that is not an option for our app? Our app needs to support more than 10 domains. Powerful APIs such as JavaScript injection, cookie manipulation, event handlers are by default available to all domains/WebView instances even if App doesn't enable app-bound domains. Is it possible to do same for ServiceWorker?
If ServiceWorker can not be supported by default then can Apple provide a feature by which ServiceWorker will be enabled in App for all the domains?
Apple enforces maximum of 10 app-bound domains. Is it possible to remove this limit and provide a way to dynamically add to this list at the time of a request?
[1] https://developer.mozilla.org/en-US/docs/Web/API/ServiceWorker#browser_compatibility
[2] https://webkit.org/blog/10882/app-bound-domains/
In our project, we download H5 resources to the local device and then open the H5 pages through WKWebView(-loadFileURL:allowingReadAccessToURL:). When the H5 pages request server resources, cookies are required.
Before opening the H5 page, we set the required cookies in the WKHTTPCookieStore using the setCookie method. Additionally, we set the allowFileAccessFromFileURLs and allowUniversalAccessFromFileURLs properties for the WebView.
On other mobile phones, the cookies can be carried normally. However, on mobile phones running the iOS 18.0 system, the cookies cannot be carried. Moreover, this problem only emerged after we upgraded Xcode to version 16.2.
We've also tried injecting cookies via JavaScript, but it didn't work(document.cookie = xx=${xx}; path=/; expires=weekday, xx jan xxxx xx:xx:xx GMT; Domain=example.com; Secure; SameSite=None ;).
Can anyone help me on this?
Thanks in advance.
Hello everyone,
In my application, i have implemented authentication using ASWebauthenticationSession. However, when redirecting the user to a WKWebView, no cookies are shared, causing the session to be lost and requiring the user to log in again.
Is there a way to share cookies between the two? If not, what would be the best approach to set up authentication that ensures SSO when switching to a WebView ?
Thank you very much for your help !
Our app is an enterprise app via MDM.
We are experiencing an issue in iPadOS 18.4 when loading an internal HTTPS server via WKWebView in a hybrid iOS app.
Our server uses a self-signed certificate but lacks the digitalSignature usage in its Key Usage extension. (Currently we have no chance to change the server's certificate)
We override webView:didReceiveAuthenticationChallenge:completionHandler: to trust the certificate:
completionHandler(NSURLSessionAuthChallengeUseCredential, credential);
This "completionHandler" works in previous 18.3.2 , but not work in 18.4. May I know is there any changes in 18.4 for the https certification? Why this delegate not work? What we can do to ignore this ssl error and get connection?
Thanks in advance, look forward for your reply.
We are experiencing a compatibility issue with our hybrid app related to the recent update in iPadOS 18.4, specifically concerning HTTPS connections.
What are the key changes introduced in iPadOS 18.4 regarding HTTPS connections? Our app previously managed to bypass the DigitalSignature key usage missing error in the self-signed server certificate within the didReceiveAuthenticationChallenge method, as documented here: https://developer.apple.com/documentation/webkit/wknavigationdelegate/webview(_:didreceive:completionhandler:) . However, since the update to iPadOS 18.4, this method is no longer being called, resulting in direct failure of HTTPS connections.
We are using cordova-ios 7.1.
Thanks in advance for your help.
