I’ve been working on a personal iOS project for fun — essentially a YouTube music player, learning how background media playback works in native iOS apps.
After seeing that Musi (a famous music streaming app) can play YouTube audio in the background with the screen off — I got really curious. I’ve been trying to replicate that basic background audio functionality for YouTube embeds using WKWebView. I've spent a crazy amount of time (probably 20 hours) trying to figure this out but have achieved no success.
Here’s what I’ve tried so far:
-Embedding a YouTube video in a WKWebView
-Activating AVAudioSession with .playback and setting .setActive(true)
-Adding the UIBackgroundModes key with audio in Info.plist
-Adding the NSAppTransportSecurity key to allow arbitrary loads
--Testing on a real device (iPhone 14, iOS 18.1 target)--
What happens:
Audio plays fine in the foreground.
If I exit the app and go to the lock screen quickly enough (less than 3 seconds) after pressing play, I can resume playback briefly from the lock screen — but it doesn’t automatically continue like in Musi and other apps like it.
Most of the time, the audio stops when the app is backgrounded.
I get this error consistently in the logs:
Error acquiring assertion: <Error Domain=RBSServiceErrorDomain Code=1 "(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)"
It seems like the app lacks some specific entitlements related to WebKit media playback. I don’t have AppDelegate/SceneDelegate (using SwiftUI), but can add if needed.
I’m super curious how music streaming apps using youtube as a source get around this — are they doing something different under the hood? A custom player? A SafariViewController trick? Is there a specific way to configure WKWebView to keep playing in the background, or is this a known limitation?
Would really appreciate any insight from folks who’ve explored this before or know how apps like Musi pulled it off.
Thanks in advance!
An Administrator account is executing safaridriver --enable but it doesn't apply to other standard user accounts and standard accounts can't enable it directly. Is this expected behavior? How can standard users make use of safaridriver?
I have a website that has been built in Wordpress and hosted on wordpress engine. In testing now and on the i phone with safari browser it keeps crashing after short time 2/3 minutes, content does not display properly pages go blank etc. Has anyone experienced this /have a solution? Thanks
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?
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.
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?
Hi Apple Devs & WebKit Team,
We operate https://excnum.com — a personal website currently under reconstruction. It's HTTPS-secure, hosted on a clean VPS, and now features a simple placeholder page with no active forms, scripts, or external redirects.
However, Safari on both iOS and macOS is flagging it as a “deceptive website”, blocking all access. This warning appears even though:
The site uses a valid SSL certificate via Cloudflare
There are no redirects, tracking scripts, or dynamic code
We serve a static landing page (“under maintenance”) with zero interaction
No malware, phishing, or obfuscation exists — verified with multiple tools
A review request has already been submitted at: https://websitereview.apple.com
We believe the site may have been blacklisted previously under past ownership or prior configurations. It has since been completely restructured and cleared, but the Safari warning persists.
This false flag is harming visibility and trust for an otherwise neutral website.
Any advice on how to expedite re-evaluation or request a manual delisting from the deceptive site list would be much appreciated.
Thank you!

iOS 26 introduced a significant step back for PWAs - you now need at least five taps to add a PWA to your home screen.
Android has excellent PWA support - it takes 1 tap to install an app, and the platform support is great, and web apps feel amazing. The gap between the platforms has now increased even further.
My team and I were hoping for better PWA support, but now we are very worried about the direction - it puts us in a difficult situation.
I'm sure many developers face a similar challenge.
What's the current status of PWAs in iOS? Is Apple aiming to improve its support in the near future? Is there a roadmap, tech previews, or betas addressing the issue?

I would like to know if there is a way to disable Smart Punctuation from the webpage rather than requiring the user to do so from the settings. Adding a "inputmode=verbatim" attribute to the input HTML tags for my webpage did that for all the web browsers I tested on Windows, Ubuntu, Android, and MacOS. I tested Chrome and Firefox on all platforms, as well as Edge on Windows and Safari on Mac and iOS. So far the only time it did not disable Smart Punctuation was on Safari on iOS, but it did on MacOS.
I've been using Sign In with Apple for Web for the last six months, and it works well enough.
Now, I'm updating the domain of the main application (we got the .com! yeah!)
However, I can't find a way in the configuration UI to update the allowed redirect URLs for the application.
I go to Identifiers -> My App -> Capabilities -> Sign In with Apple -> Edit button.
It just allows me to edit whether this is a primary ID, or grouped ID, plus a callback URL (which I'm not currently using.)
Dear Apple Developer Support,
We are currently developing a system that requires the ability to edit Japanese vertical text within the Safari browser on iPhone. During our investigation, we encountered an issue that matches the following WebKit bug:
283620 – Caret Positioning Issues in Vertical Writing Mode
We understand that this issue is being addressed in the following pull request:
https://github.com/WebKit/WebKit/pull/39939
However, it appears that a complete fix has not yet been implemented.
Given this situation, we would like to confirm the following:
Is there any known workaround for this issue in iOS 17.5 or iOS 18.5 (the latest versions as of now)?
If a workaround exists, could you please provide details?
If not, could you share the expected timeline for a full resolution of this issue?
Although this appears to be an open-source WebKit issue, we are reaching out to Apple because WebKit is tightly integrated with iOS and Safari, and ultimately delivered as part of the iPhone experience.
Thank you very much for your support.
Best regards,
Takao Kurabayashi

Hello,
As previous reports have already shown, there seems to be a few issues on the latest version of Safari, mainly around:
Modals taking up the full viewport
Elements positioned at the bottom of the screen
This also seems to affect the modals on apple.com/iphone.
I've recently done an analysis of what can and can't be done in code to work with the new liquid glass UI and thought I'd share my findings here.
The full write up, along with screenshots and the demos I used are available in this repository:
https://github.com/stevenocchipinti/liquid-glass-spike
A brief summary of the findings:
The conditions for a fullscreen modal overlay element to cover the entire screen with a position: fixed; seems to be:
The background must be semi-transparent
Solid colours, linear-gradients, etc. don't work
The container must be empty
This also means the standard and ::backdrop don't seem to work.
The conditions for a bottom sheet to cover the entire screen, including the area around the Safari toolbar seems to be:
The element must be positioned within 3px from the bottom of the viewport
The height must be within a certain threshold
If I've missed anything, please let me know.
It would be really nice to have some official documentation on these issues to explain to developers how to do this properly.
window.location.href = 'tel:0216700310'; I ran the code in an IOS environment. The number was displayed when the call button on the device appeared. However, other IOS devices besides some devices came out as a number starting with +82, and I received feedback that the call was not connected properly. I wonder what could be caused by only some devices. And I would also like to ask what can be done to allow the numbers on the code to be displayed and called as they are.

Hello everyone,
We've had our app rejected twice under Guideline 3.2.2 regarding charitable donations, and we're seeking clarification on the correct implementation. We've read the guidelines but want to confirm the technical approach with the community's experience.
The Rejection Reason:
Apple states: "We still noticed that your app includes the ability to collect charitable donations within the app..." They specify that since we are not an approved nonprofit, we must use one of the alternatives, primarily: "provide a link to your website that launches the default browser or SFSafariViewController for users to make a donation."
Our Current (Rejected) Implementation:
User taps a "Help" button in our native app.
A native modal appears inside our app where the user enters their donation amount and email address for the receipt.
The user clicks "Donate," which then opens an SFSafariViewController to our website's payment page (e.g., Stripe, PayPal). The amount and email are passed as URL parameters to pre-fill the form.
Our Questions for the Community:
Is the issue solely the fact that we have a native modal for data entry? We understand we cannot process the payment in-app, but we thought collecting the intent (amount, email) was acceptable before handing off to Safari.
What is the definitive, compliant flow?
Option A: Should the "Help" button do nothing more than open an SFSafariViewController to a generic donations landing page on our website (https://ourwebsite.com/donate), with no data pre-filled? The user must then navigate and enter all information on the website itself.
Option C: The rejection also mentions SMS. Has anyone had success implementing a "Text-to-Donate" link instead of a web flow?
Wording: The button in our app currently says "Donate". Should this be changed to a more passive call to action like "Visit Website to Donate" to make it absolutely clear the transaction is external?
We want to ensure our next submission is successful. Any insight, especially from developers who have successfully navigated this exact rejection, would be immensely helpful.
Thank you.

Hello,
I have an authentication flow where my app communicates with a backend protected by F5 client certificate validation. The client certificate is distributed via MDM and is available in the device keychain, but not accessible directly from the app.
When using ASWebAuthenticationSession (or SFSafariViewController) Safari can successfully pick up and present the certificate during authentication, so that part works fine.
However, the backend’s authenticate endpoint only supports a POST request with an Authorization header, whereas ASWebAuthenticationSession only accepts a GET URL when starting the session.
My questions are:
How is this type of flow typically implemented in iOS?
Should the backend provide a GET-based endpoint that redirects into the POST, or is there a recommended iOS pattern (e.g., an intermediate HTML page that does the POST after certificate validation)?
Are there Apple guidelines on handling certificate-based auth with ASWebAuthenticationSession when the API requires POST, especially for In-House distributed apps?
Any guidance or best practices would be very helpful.

We are encountering a download issue in Safari 18.2 on macOS Sequoia 15.2 where file downloads initiated by our AngularJS application (such as Excel exports) are silently blocked.
There are no errors in the browser console, and the download does not occur.
Interestingly, after testing on Safari 18.3 with Sequoia 15.3, the downloads worked as expected.
However, the problem reappeared on Safari 18.4 with Sequoia 15.4.
We suspect that recent changes in Safari’s security or download handling may be preventing downloads triggered via asynchronous JavaScript (e.g., AJAX calls) that are not initiated directly by user interaction.
We would appreciate any insights, suggestions, or possible workarounds from the community. Looking forward to your guidance on this matter.
Environment
• 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];

If we use webView.loadFileURL(indexURL, allowingReadAccessTo: readAccessURL) on an iPad it loads the data and navigation works.
But if we place two hands on top of the screen and move a bit, all click events are not working anymore.
It works again if we call loadFileURL again.
We filled a bug report:
