Hello Apple App Review Team,
We are using Privy to enable sign in with Farcaster in our app. Privy is a 3rd party authentication SDK, and it currently opens the authentication URL using the system browser.
Unfortunately, this behavior is handled internally by Privy and we do not have access or control to override it in order to present the sign-in flow in-app using SFSafariViewController.
We understand the importance of maintaining a seamless and secure user experience, and we fully support the use of SFSafariViewController or ASWebAuthenticationSession. However, since Privy does not expose an option to change this behavior at the moment, we are limited by their current implementation.
We have reached out to the Privy team requesting a change or improvement that would allow us to use SFSafariViewController instead of the external browser. In the meantime, we would appreciate your guidance on how to proceed, or whether an exception could be granted due to this 3rd party SDK limitation.
Thank you for your understanding and support.

I have a very specific issue that happens only on iOS Simulator version 18.4.
It does NOT happen when I run my app on a real iOS 18.4 device through Testflight.
My app displays a WebView (courtesy of Capacitor, url scheme capacitor://).
Inside that Webview I'm using Firebase JS API (11.2.0) and calling signInWithEmailAndPassword, which works well in all other contexts, i.e. browser, Android webview, iOS webview in all other Simulator versions, and on real devices.
Only when running in Simulator 18.4, I get a failed network request:
cannot parse response
Fetch API cannot load https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?... due to access control checks.
Failed to load resource: cannot parse reponse
error: FirebaseError: (auth/network-request-failed)
Everything is working correctly for both:
Capacitor app webview installed on a real 18.4 device with Testflight
Safari (non-webview) in the 18.4 Simulator
The issue is severe for us, because we are unable to develop our app and test it in the simulator on 18.4 Simulator before pushing it through Testflight internal release.
Request headers on the failed request (no response status or headers available).
Request
Accept: /
Content-Type: application/json
Origin: capacitor://localhost
Sec-Fetch-Dest: empty
Sec-Fetch-Mode: cors
Sec-Fetch-Site: cross-site
User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 18_4 like Mac OS X) - AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148

Steps to Reproduce:
Open the Bing search page in Safari (example URL: https://www.bing.com/search?q=webkit&form=APIPH1&PC=APPL).
Pinch-zoom in or out, then return the page to exactly 100% zoom.
Rotate the device from portrait to landscape orientation.
Observe that the page is incorrectly scaled to a value other than 100%.
Rotate the device back to portrait orientation.
The page remains at the incorrect zoom level.
Expected Result:
After returning the page to 100% zoom, changing orientation should keep the zoom level at exactly 100% in both portrait and landscape modes.
Actual Result:
After returning to 100% zoom, rotating to landscape changes the zoom to a non-100% value, and rotating back to portrait retains the incorrect zoom level.
Hello,
When I view my website (lasaluade) on iphone or ipad the top of my page bodies are cut off (3-4 first lines). However, on PC, Mac or Android everything is OK (see screenshots).
For the record, I built this site with Wordpress and Divi Builder, and I've the same result on Safari and Chrome.
Not being a developer, I don't know where to look (I just think it's iOS-related).
Have you already had this problem? Do you have any ideas?
Thanks for your help!

Good morning fellow developers,
For a while i am struggeling with providing sound to my users on IOS (Safari on Mac is no problem and every other device is not a problem) (we have an existing phone system and made a chat as well), the case is very simple: the notification sound is only for users who are logged in and online for chat.
i have tried multiple things:
Audio play with javascript (start with mute, play when user clicks a button so the sound is familiar, play when user clicks a button and directly pause it and continue when needed)
PWA: the dashboard has been made available as pwa and notifications using google firebase. The popup does show for notifcations to be allowed (and receiving the notifications does work on any other device) But any IOS device cannot register.
The information i find is that notifications were supported with 16.4 or higher but also have been deprecated around IOS 17, auto play is not allowed.
We have an app in development for our product as well were we will have a notification which will handle this, but that is not the solution we can use now.
Long story, short question: is it still somehow possible to push a notification to the user when using the PWA or play a sound in the browser (based on an ajax function). The app/website wont be in the background, so it will always be on the screen.
Languages we use: html/javascript (mostly vanilla)/php
Hello from Leipzig, Germany!
I noticed that when vertically scrolling in Safari 26 on my Mac, the content of the website I am currently working on is visible in the tab and URL bar with a liquid glass effect. I then looked at various other websites. Some websites have an opaque top bar. Some websites have a transparent top bar where content is visible when scrolling. On the Apple website, the top bar is opaque in light mode but transparent in dark mode. Unfortunately, I can't find a way to control this behavior. Has anyone found out more about this?
Our app connects to the headend to get a IDP login URL for each connection session, for example: “https://myvpn.ocwa.com/+CSCOE+/saml/sp/login?ctx=3627097090&acsamlcap=v2” and then open embedded webview to load the page. (Note: the value of ctx is session token which changes every time). Quite often the webview shows blank white screen. After user cancel the connection and re-connect, the 2nd time webview loads the content successfully.
The working case logs shows:
didReceiveAuthenticationChallenge is called
decidePolicyForNavigationAction is called twice
didReceiveAuthenticationChallenge is called
decidePolicyForNavigationResponse is called
didReceiveAuthenticationChallenge is called
But the failure case shows:
Filed to terminate process: Error Domain=com.apple.extensionKit.errorDomain Code=18 "(null)" UserInfo={NSUnderlyingError=0x11461c240 {Error Domain=RBSRequestErrorDomain Code=3 "No such process found" UserInfo={NSLocalizedFailureReason=No such process found}}}
didReceiveAuthenticationChallenge is called
decidePolicyForNavigationAction is called
decidePolicyForNavigationResponse is called
If we stop calling evaluateJavaScript code to get userAgent, the blank page happens less frequently. Below is the code we put in makeUIView():
func makeUIView(context: Context) -> WKWebView
{
if let url = URL(string: self.myUrl)
{
let request = URLRequest(url: url)
webview.evaluateJavaScript("navigator.userAgent")
{
result, error in
if let error = error
{
NSLog("evaluateJavaScript Error: \(error)")
}
else
{
let agent = result as! String + " " + self.myUserAgent
webview.customUserAgent = agent
webview.load(request)
}
}
}
return self.webview
}
Found some posts saying call evaluateJavaScript only after WKWebView has finished loading its content. However, it will block us to send the userAgent info via HTTP request. And I don’t think it is the root cause since the problem still occurs with less frequency.
There is no problem to load same web page on Windows desktop and Android devices. The problem only occurs on iOS and macOS which both use WKWebview APIs.
Is there a bug in WKWebview?
Thanks,
Ying
Hello,
We are setting up Apple Sign In in one of our non production websites but we keep getting a "oauth code says expired or revoked" error. We have created a brand new service ID and key for this but are still getting this error.

I have compiled some Java code to WebAssembly via TeaVM and wrapped it in a PWA. The resulting code runs nicely in Firefox and Chrome but throws an exception in Safari.
CompileError: WebAssembly.Module doesn't parse at byte 1657: invalid extended GC op 24, in function at index 2251
Can anybody tell me what's wrong with that code? I mean it can't be so bad if Firefox and Chrome can parse and run it without problems. I am using the most recent versions of all browsers and the offending code can be found here:
Run the demo via: https://mpmediasoft.de/demos/Emmentaler/Emmentaler-Demo-TeaVM-Wasm/index.html
The offending wasm file is: https://mpmediasoft.de/demos/Emmentaler/Emmentaler-Demo-TeaVM-Wasm/tvw/ModelBridgeTeaVM.wasm
With Safari the demo just shows some empty space instead of a complex polygon. You can see the error in the javascript console of Safari.

現在新しいWebViewを使ってwebページを読み込むiPadプログラムを作成中ですが、読み込んだ後に部分のボタンをタップしても何も起こりません。safariで通常通りページを開いてボタンをタップするときちんと写真ライブラリ・カメラで撮るなどのポップアップが表示されます。下記がコードです。Webページは単純化のためにのみを配置しています。
struct SwiftUIWebView: View {
@State private var webPage = WebPage()
private let url = URL(string: "https://www.****.com/")!
var body: some View {
WebView(webPage)
.onAppear {
// URLを読み込む
webPage.load(URLRequest(url: url))
}
}
}
何か追加のコードが必要なのでしょうか?
Hello all,
I'm trying to retrieve geolocation data on the web, but I'm having trouble with the altitude value, which seems to differ from what I get on Android.
When using navigator.geolocation.getCurrentPosition in Safari, is the altitude value based on mean sea level, or is it ellipsoidal altitude based on the WGS84 ellipsoid?
altitude (WebKit JS): https://developer.apple.com/documentation/webkitjs/coordinates/1631861-altitude
altitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/altitude
ellipsoidalAltitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/ellipsoidalaltitude
If anyone has any insight into this topic I would greatly appreciate it!
How can I make a background image take the entire screen in ios26?
I've tried position fixed, sticky, env() css variables but nothing worked. It does it when in PWA mode, but I would like to do so in the browser too.
We’re currently working on an OTT-based application where we integrate Google Ad Manager to serve video ads. As part of the ad experience, users often see a “Learn More” CTA (Call to Action) on these ads.
As per our current requirement, when a user taps “Learn More” on an ad:
• The link should open in Safari (i.e., an external browser) on iOS devices
• The Safari browser should ideally open in portrait orientation, as the ad content and layout are optimised for portrait mode
However, based on our understanding and technical constraints on iOS, it appears that:
• Orientation control is restricted to the app’s own context.
• Once Safari is launched via UIApplication.shared.open, we no longer have control over how it behaves in terms of orientation.
• iOS system behaviour determines Safari’s orientation based on the device’s physical orientation and Safari’s own internal configuration.
Could you please confirm if there’s any supported way (via SDK, deep link config, or otherwise) to enforce portrait orientation in Safari when opening such external URLs from within an iOS app?
If this is not technically feasible, we would appreciate any best practices or alternatives you can suggest for ensuring a consistent user experience.

I built a web application using the Apple Pay on the Web Interactive Demo with the Payment Request API, but encountered a few issues:
The initiated web Apple Pay interface shows a spinning circle at the bottom and cannot proceed with payment(Bottom display:正在处理). What could be causing this?
How to set up sandbox testing for payments?
How to asynchronously and synchronously retrieve payment results (backend code to fetch payment results)? The demo only shows frontend code using await response.complete("success"); for retrieving payment results

In my chat web app I have button to upload images. On iOS in Safari I can see action sheet with "Media library", "Caption image or video", "Open files". Can I prevent opening this action sheet and directly open media library using HTML or JavaScript?
Hi everyone,
We're building a web application using Next.js that captures around 40 images across different routes as part of a guided user flow.
At the beginning of the process, we explicitly request camera permission using navigator.mediaDevices.getUserMedia(...), and the user grants it successfully.
However, as users proceed through the flow (navigating between routes), Safari on iOS intermittently re-prompts for camera access—despite the initial permission already being granted and the origin (domain) remaining unchanged.
This repeated prompting interrupts the user experience significantly.
What we’ve tried:
Ensuring camera access is requested only once and reused where possible.
Using persistent media stream across routes (where feasible).
Testing across different iOS versions to confirm consistency.
Questions:
Is there a known workaround or best practice to persist camera access across route transitions in a SPA/PWA context on iOS?
Are there any Safari-specific behaviors or restrictions related to WebRTC / getUserMedia we should be aware of?
Would embedding the camera view in an iframe or maintaining a persistent component help avoid re-prompting?
Any guidance or shared experience would be greatly appreciated.
Thanks in advance!

When a DNR rule is set for a specific URL and the request receives a server-side redirect (e.g., 302) to a different URL that does not match the urlFilter, the rule still seems to apply to the redirected request. We are using macOS 15.4 and Safari 18.4.
For example, consider two sequential calls: call1 and call2.
call1 triggers a 302 redirect to call2.
A DNR rule is created to add a "Cookie" header to call1 based on its URL.
Unexpectedly, the same cookie is also added to call2, even though call2's URL does not match the rule's urlFilter.
This results in the Set-Cookie response from call1 being ignored, and call2 receiving the manually set cookie instead—leading to incorrect behavior.
This issue doesn't occur in Chrome or Firefox, where the rule is not applied to the redirected request if the URL no longer matches.
We are looking for assistance in fixing these issues and having our Safari Extension function the same as it does in Firefox and Chrome.
Hello,
can't find a better Forum and after all this is Apple Support here?
Seems starting with iOS 26.2 RC2 our Newsletter is no longer rendered 'responsive' so with unuseable small font.
Anybody any suggestion? Or maybe @apple fix the bug?
Where would I even start to debug this? I don't have any iphone at hand so i only got screenshots from users.
Our where can i contact the actual apple support?

Hello there,
For a video like this <video src="blob:safari-web-extension://***" autoplay="" loop="" style="position: absolute; top: 0px; left: 0px; width: 100%; height: 100%; object-fit: cover; z-index: -1;"></video>, no matter if its local or remote, blob or mp4 files, is constantly being reloaded (refetched? revalidated?) if the loop tag is added. I can confirm there is actual constant traffic from the server based on my server logs. I am running iOS/macOS 26.
