Since the transition to iOS 18.4, we have been having an issue where when loading an m3u8 file specified in the src attribute of a video tag in WKWebView, the ts file is loaded repeatedly.
Are there any good ideas for this?
Also, if there have been any changes to the specifications of WKWebView, we would appreciate it if you could let us know.

I'm creating an iPad app using Xcode 26 Beta 6. I have the following simple code and web page, but when I tap the file selection button, nothing appears. Do I need to add any additional code?
code
struct SwiftUIWebView: View {
@State private var webPage = WebPage()
private let url = URL(string: "https://www.xxxx.com/")!
var body: some View {
WebView(webPage)
.onAppear {
webPage.load(URLRequest(url: url))
}
}
}

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.
Steps to Reproduce
1. Create a native UIViewController with a WKWebView, loading test-1.html (contains position:fixed header that displays correctly).
2. Push another UIViewController also with a WKWebView, this time loading test-2.html.
3. In test-2.html, tap into the to summon the on-screen keyboard.
4. Without calling blur(), perform an interactive swipe-back gesture to go back to the first view controller.
5. Observe that the fixed header in test-1.html is now offset downward by approximately the height of the keyboard and does not return to its original position.

Our UI-less share extension (com.apple.services) appears in Safari and Chrome. We raise a popup "Open in (app)..." via the Action.js script document.location.href = urlScheme://... in Safari.
However, in Chrome, while our extension executes, parses the URL item attachment from Chrome, it never triggers that popup or opens our app.
How can a UI-less share extension open our app from Chrome?
Is the accepted practice, despite guidelines, turning the com.apple.ui-services view controller invisible and auto-openURLing? Several apps on the store appear to do this, immediately popping their app without any confirmation dialog or UI in both Safari and Chrome. https://stackoverflow.com/a/79369242
Hi!
My SwiftUI app is a rather complex browser app. Starting with iOS 18, the app crashes due to repeted reloads of the WkWebView. I’ve tracked the issue as far as I can, but I still haven’t found the root cause.
My app is structured like this:
MainView holds a cuple of subviews. It also holds a @StateObject called viewModel that holds a lot of @Published vars. The viewModel is passed as a enivormentObject.
Example from ViewModel:
@MainActor class ViewModel: NSObject, ObservableObject {
@Published public var isLoading: Bool = false
@Published public var loadProgress: Double? = 0
public func setIsLoading(_ value: Bool) async {
self.isLoading = value
}
public func setLoadProgress(_ value: Double?) async {
self.loadProgress = value
}
}
WebView is a subview of MainView, which holds a navigation bar, and a UIViewRepresentable, which is a WkWebView.
The WkWebView pushes some states to the ViewModel as the underlying values of the WkWebView changes, i.e. estimaedProgress, and isLoading. This is done via KVO and works like this:
estimatedProgressObservation = self.parent.webView.observe(\.estimatedProgress) { webView, progress in
Task {
await parent.viewModel.setLoadProgress(webView.estimatedProgress)
}
}
isLoadingObservation = self.parent.webView.observe(\.isLoading) { webView, value in
Task {
await parent.viewModel.setIsLoading(webView.isLoading)
}
}
By using a timer in WkWebViews Coordinator, i trigger a load after a configurable amount of time :
func loadUrl(url: URL) {
DispatchQueue.main.async {
console.info("Load URL: ...", sensitive: "Load URL: \(url.absoluteString)")
let policy: NSURLRequest.CachePolicy
if self.parent.settings.noCache {
policy = .reloadIgnoringLocalAndRemoteCacheData
} else {
policy = .useProtocolCachePolicy
}
let request = URLRequest(url: url, cachePolicy: policy)
self.parent.webView.load(request)
}
}
Running the app with the automatic reload enabled freezes the app after a couple of hours. It also seems to freeze Safari on the device. The device needs to be rebooted.
If I inspect the device's running processes, hundreds of ”com.apple.webkit. web content " processes are running.
Removing await parent.viewModel.setLoadProgress(webView.estimatedProgress) and await parent.viewModel.setIsLoading(webView.isLoading) fixes the issue, but it is necessary for other app functions. Therefore, is suspect that the viewModel somehow causes the bug.
The issue arises after a couple of loads 5-10. The debugger shows a message when the processes start to pile up. I suspect its related.
Failed to terminate process: Error Domain=com.apple.extensionKit.errorDomain Code=18 "(null)" UserInfo={NSUnderlyingError=0x12d0e7f60 {Error Domain=RBSServiceErrorDomain Code=1 "Client not entitled" UserInfo={RBSEntitlement=com.apple.runningboard.terminateprocess, NSLocalizedFailureReason=Client not entitled, RBSPermanent=true}}}
How can I find out what causes the suspected memory leak? Instruments gives me nothing of value. The memory leak wasn't present in iOS 17. Is this a bug in iOS 18, or was something intentionally changed?
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!

I have an endpoint that generates a .ics file. From my mobile app, I open the browser (Safari) and retrieve the .ics file. In Safari, the events are displayed as expected, and I can use the "Add All" button to add them to the calendar. After clicking "Add All," I can select the desired calendar, and the events are successfully added (see screenshots 1 and 2 below).
Here’s the initial .ics file response:

Later, I updated the .ics file with new event details:

I updated everything according to the iCalendar documentation:
UID remained unchanged
SEQUENCE has been updated
DTSTAMP has been updated
LAST-MODIFIED has been updated
However it seems like that Safari can't handle updates on events.
In the preview we can see the changes, but when I click on "Add All" button, nothing happens.
The same behavior is working with other calendars like Outlook (web view) or Google Calendar.
My Questions:
Is there a property missing from my .ics file that is necessary for iOS Safari to handle updates?
Is Safari not designed to handle event updates in this way?
Should I consider moving to a subscription-based solution to manage updates more reliably?
Any insights or suggestions would be greatly appreciated!
Hi folks!! Anyone here experienced issues with video not showing up in webview?
I have a simple index.html with a video tag but its doesn't load why?
While implementing Apple Maps into our web application, I have a scenario where I want to be able to drag and move some of my custom annotations around. While that is working, when "picking up" the annotation before dragging it, there is an animation which I believe is to represent the human interaction of picking up a pin from a map, I would like to cancel that animation and thought that would be possible by calling preventDefault() in the emitted long-press event, which the documentation states that annotations should emit if they are draggable. The thing is that I don't get this event to emit when long pressing an annotation. So I believe that I have found a bug.
It's in this paragraph in the documentation https://developer.apple.com/documentation/mapkitjs/handling-map-events#Respond-to-map-interaction-events
A long press occurs on the map outside an annotation. A long press may be the beginning of a panning or pinching gesture on the map. You can prevent the gesture from starting by calling the preventDefault() method of the event. Annotations need to be draggable to dispatch long-press events.
In anybody else experiencing this or do you see any clear fix for this? Maybe there is another way to cancel that "picking up the annotation for dragging" animation. I have seemed to try anything else.
Hello,
I am developing a website which starts a web worker using the js code:
const zarrWorker = new Worker('./zarr_file.js', { type: 'module' });.
The script 'zarr_file.js' is served from the same origin with Cross-Origin-Embedder-Policy: require-corp and Cross-Origin-Opener-Policy: same-origin and it is importing external modules through the import statement (e.g. import * as zarr from "https://cdn.jsdelivr.net/npm/zarrita/+esm";).
All the external modules are blocked by Safari with the error Worker load was blocked by Cross-Origin-Embedder-Policy, although I can see (by running curl on them) that they correctly set cross-origin-resource-policy: cross-origin`.
The same website works fine in Chrome and Firefox.
Is it a bug or is Safari implementing stricter policies? In the latter case what would be the solution?

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];

Hi there, we have found a problem, after switching audio tracks multi times when play the HLS, there will be a few seconds of no sound playing after audio track switching, Is there a solution to this problem?
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.
In the Safari browser on mobile devices, the tags in an HTML element are styled with the system's default styles. I want the text inside the tags to be displayed without line breaks. However, in reality, the text wraps according to its length. May I ask if there are any methods to achieve this?
(ps: CSS-related properties such as white-space: nowrap do not work.)
How did you test apple-app-site-association in non-production environments that are usually not public?
