Apple Pay on the Web fails with an "AbortError" in production
Apple Pay fails with an "AbortError" when the dialog for the fingerprint sensor opens. How do I find the cause of the "AbortError" which only occurs in the web integration in our production environment? In the sandbox environment, Apple Pay works flawlessly. This concerns a web integration of Apple Pay using the Apple Pay SDK, one version before 1.2.0. The error occurs when I call the show() method on the PaymentRequest object. The Apple Pay dialog opens with the fingerprint icon, but after one second, an exclamation mark appears, and the Apple Pay dialog closes again while throwing the "AbortError". I know that our Apple Pay integration worked for multiple customers in the production environment already. The current problem is that Apple's error message, called "AbortError," provides no indication of the cause. This could be greatly improved. One affected customer, for example, is the one with the Merchant ID … (Is it safe to post a Merchant ID in this forum?) I can reproduce the "AbortError" issue at any time using my iPhone with iOS 16.7.8.

Issue sending web push notification to iOS
Hello all, I'm building a web application in ASP.NET MVC (.NET Framework 4.7.2), from this web app I need to send push notifications to users. For the ones who are logged in with windows/android, everything works as expected, but I can't manage to get it work on the apple side. If I use the same methods to subscribe to push notifications, it shows me the popup that asks the user to enable push notifications, and then I get an endpoint like this: https://web.push.apple.com/QKC1Muic0H7... It doesn't work using this (taking the part after https://web.push.apple.com/), I keep getting "Bad device token" (trying to send the notification via APNS). Then I found out that there is another method to register the device from the frontend, and this one should give me the real device token: window.safari.pushNotification.requestPermission But this one doesn't show me the popup, it gives me "denied" without a reason. I'm trying to a test application which is here https://pwa.vctplanner.it, the web push id is web.it.vctplanner, I created a push package downloadable from POST https://pwa.vctplanner.it/api/v2/PushPackages/web.it.vctplanner, and the code from the frontend is this: function registerSafariPush() { // Controlla se Safari Push Notifications è disponibile if (!('safari' in window) || !('pushNotification' in window.safari)) { console.log("Safari Push Notifications non supportate su questo browser."); return; } // Il tuo Website Push ID registrato su Apple Developer var websitePushId = "web.it.vctplanner"; // Controlla lo stato della permission var permissionData = window.safari.pushNotification.permission(websitePushId); switch (permissionData.permission) { case 'default': // L'utente non ha ancora deciso window.safari.pushNotification.requestPermission( 'https://pwa.vctplanner.it', // URL del server che serve il Push Package websitePushId, {}, // dati opzionali da inviare al server function (permission) { if (permission.permission === 'granted') { console.log("Notifiche push abilitate!"); sendSubscriptionToServer({ endpoint: permission.deviceToken }); } else { console.log("Notifiche push non abilitate dall'utente."); } } ); break; case 'denied': // L'utente ha negato console.log("Notifiche push negate."); break; case 'granted': // L'utente ha già autorizzato console.log("Notifiche push già autorizzate."); sendSubscriptionToServer({ endpoint: permissionData.deviceToken }); break; } } Any suggestions of what I'm missing? Is there a complete guide to how generate the push package? Thank you

Apple Messages strips URL from HTML clipboard
Hi there, I use the Clipboard API to create formatted project links with a "copy link" button. This has been really versatile for end users. When they paste into their email, they get a hyperlinked project name that leads to the project, and when they paste into the URL bar, they just get the project URL. It used to be that pasting into Messages on Mac would yield the same behavior as pasting into the URL bar. But recently, Messages started only pasting the inner text of the HTML clipboard, so no URL, just the project name, which isn’t very useful for a copy link function. Is there any way to ensure that Messages pastes the URL while maintaining my formatting options on other surfaces?

MacOS Tahoe - Traffic is not routed through PAC file
I am using a custom PAC file in network settings and till now with Sonoma & Sequoia OS, it was working perfectly fine and I was able to redirect traffic to my proxy server. After upgrading to MacOS Tahoe, this stopped working completely. What is happening now is no url is opening on my machine with Chrome & Firefox browser, but somehoe Safari is working. After checking, I found that my deployed network extension is intercepting traffic and allowing it to pass. But still, the pac file is not working. Are there any changes done in MacOS Tahoe regarding this PAC file? How can I resolve this issue?

window.location.href = 'tel:0216700310'
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.

Safari Does Not Include topOrigin in WebAuthn clientDataJSON Despite crossOrigin: true
Hello, I’m working on a cross-origin WebAuthn implementation where a parent page embeds an iframe from a different origin to perform authentication. According to the WebAuthn Level 3 spec (Section 7.1.1), when crossOrigin is true, the clientDataJSON may include topOrigin—but Safari does not seem to populate this field. Observed Behavior: Chrome/Firefox: Include topOrigin in clientDataJSON when crossOrigin: true. Safari (macOS/iOS): Omits topOrigin even though crossOrigin is correctly set to true. Example clientDataJSON from Safari: { "type": "webauthn.get", "challenge": "...", "origin": "https://iframe-origin.example.com", "crossOrigin": true // Missing `topOrigin` (expected: parent origin) } Questions: Is this an intentional omission in Safari for privacy/security reasons? Are there specific requirements (e.g., HTTP headers, permissions policies) needed for Safari to expose topOrigin? Is there a known workaround to reliably obtain the top-level origin in cross-origin WebAuthn flows? System Info: Version 18.4 (20621.1.15.11.10) OS: Sequoia Version 18.4 (20621.1.15.11.10) Reproduction Steps: Parent page (https://parent.example.com) embeds an iframe (https://webauthn-rp.example.com). The iframe calls navigator.credentials.get() with a WebAuthn challenge. Safari returns clientDataJSON with crossOrigin: true but no topOrigin. Code Snippet (iframe): const credential = await navigator.credentials.get({ publicKey: { challenge: new Uint8Array(/* ... */), rpId: 'webauthn-rp.example.com', allowCredentials: [], hints: [], userVerification: "preferred", } }); console.log(JSON.parse(atob(credential.response.clientDataJSON))); Has anyone encountered this? Any insights would be greatly appreciated!

Manage Safari 26 top bar transparency (Mac)
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?

Issue with Safari and webserver with unencrypted HTTP traffic
We seem to be having an issue with a webservice here which is used within our network and IOS Safari. For the service to work , we need to access it with an unencrypted HTTP API call, which acts as a trigger. The server does not respond to HTTPS requests. (the HTTP API call does not contain any data that is privacy sensitive or that can be abused) Since recently the service does not seem to work anymore properly, but this only happens with Safari and IOS. With all other browsers the service is still working normally, only with Safarai it fails. No matter what I do in the settings of the phone, the Safar browser seems to stop immediately after the HTTP request. What is going on here ?? The issue seems to occur only when you don't have an iCloud+ account. With an iCloud+ account I get the same issue when you switch Apple Private Relay on, but that make sense. When I have Apple Private Relay switched off, there is no issue.

Unwarranted Autofill prompt for non authenticator grid boxes
On Mac, If the user registers the Password and the Software Authenticator app for a website like PayPal then uses the Safari browser to login the Apple system is creating confusion. The system prompts to use the authenticator autofill for any grid like SMS OTP or even for the Email OTP. That creates confusion for the user as the SMS OTPs or other OTPs cannot be validated by auto filling the Authenticator TOTP. That fails the validation resulting in bad user experience. The system should not prompt the Autofill from the Authenticator app unless the grid box shown on the page was for the Authenticator app.

XMLHttpRequest cannot load https://demo2.artios.cz/app37g/v105/php/endpoint.php due to access control checks
Hi, we are experiencing a strange issue with our Web App. Our web app runs entirely on the same domain , and we are making several AJAX requests to the same server. The Error occurs only on Iphones, the app works completely fine on androids and computers. Most of the requests work fine, but suddenly, one specific request always fails with the following error: XMLHttpRequest cannot load https://demo2.artios.cz/app37g/v105/php/endpoint.php due to access control checks What we have checked so far: ✅ CORS headers seem correct. Also we operate entirely on the same domain, client and server. ✅ The same request works fine in computer and android devices. ✅ The issue occurs only on iPhone (tested on Chrome and Safari). ✅ Some requests to the same endpoint pass, but suddenly, this specific request always fails. ✅ There is no OPTIONS preflight request logged in the network tab, but we use only simple requests. ✅ We are making a POST request with multipart/form-data. What is Your advice, or where I can find more info about this error? We do not think the CORS is the problem. We have tried to inspect with WebInspector but with no relevant answers. Thank You very much!

Please Help: WKwebview not allowing background audio playback
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!

Disable Smart Punctuation from Webpage
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.

TLS re-negotiation fails with ios18.4
I'm running apache with following configuration. /cc require TLS client certificate / not require TLS client certificate Starting with ios 18.4, accessing /cc after / fails with following error: AH02261: Re-negotiation handshake failed, referer: https://www.example.com/... SSL Library Error: error:1417C0C7:SSL routines:tls_process_client_certificate:peer did not return a certificate -- No CAs known to server for verification? It seems like ios 18.4 does not support TLS re-negotiation. (It worked with ios 18.3 and before) Is this an expected behavior or a bug?

CSS not displaying when using WKURLSchemeHandler on iOS 17+ with Xcode 15.3+
I’m encountering an issue with CSS not displaying when using WKURLSchemeHandler to load local HTML files. When I package the app using Xcode 15.3 or above, the CSS styles do not display on iOS 17 or higher. However, on iOS 16.7.1, the CSS displays correctly. • If I use Xcode 15.2 to package the app, the CSS loads and displays correctly on all iOS versions. I am using WKURLSchemeHandler to intercept and load the local HTML files. Is there any known issue or workaround for this? You can now post this in the “Safari & Web” section of the Apple Developer forums for further assistance! // // CustomURLSchemeHandler.m // HTMLTest // // Created by lvxue on 2024/9/23. // // CustomURLSchemeHandler.m #import "CustomURLSchemeHandler.h" @implementation CustomURLSchemeHandler - (void)webView:(WKWebView *)webView startURLSchemeTask:(id<WKURLSchemeTask>)urlSchemeTask { NSURL *url = urlSchemeTask.request.URL; //NSString *filePath; NSString *filePath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"LoaclHtml.bundle/A4"]; if ([url.lastPathComponent hasSuffix:@".css"]) { filePath = [[NSBundle mainBundle] pathForResource:@"style" ofType:@"css" inDirectory:@"LoaclHtml.bundle/A4/css"]; } else if ([url.lastPathComponent hasSuffix:@".js"]) { filePath = [[NSBundle mainBundle] pathForResource:@"yourJSFileName" ofType:@"js" inDirectory:@"LoaclHtml.bundle/A4/js"]; } NSData *htmlData = [NSData dataWithContentsOfFile:filePath]; NSString *mimeType = [self mimeTypeForPath:filePath]; NSURLResponse *response = [[NSURLResponse alloc] initWithURL:url MIMEType:mimeType expectedContentLength:htmlData.length textEncodingName:@"utf-8"]; [urlSchemeTask didReceiveResponse:response]; [urlSchemeTask didReceiveData:htmlData]; [urlSchemeTask didFinish]; } - (void)webView:(WKWebView *)webView stopURLSchemeTask:(id<WKURLSchemeTask>)urlSchemeTask { } - (NSString *)mimeTypeForPath:(NSString *)path { NSString *fileExtension = [path pathExtension]; if ([fileExtension isEqualToString:@"html"]) { return @"text/html"; } else if ([fileExtension isEqualToString:@"css"]) { return @"text/css"; } else if ([fileExtension isEqualToString:@"js"]) { return @"application/javascript"; } else if ([fileExtension isEqualToString:@"png"]) { return @"image/png"; } else if ([fileExtension isEqualToString:@"jpg"] || [fileExtension isEqualToString:@"jpeg"]) { return @"image/jpeg"; } else if ([fileExtension isEqualToString:@"gif"]) { return @"image/gif"; } return @"application/octet-stream"; } @end code-block

Is Apple aiming to improve PWA support in iOS?
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?

Issue with SFSafariViewController Not Always Detecting Redirect After Stripe Payment
I am using SFSafariViewController to process payments via a Stripe checkout URL. Once the payment is completed, the user is redirected to a success URL. I have also added associated domains for deep linking. Below is my implementation: func presentCheckout(url: String) { showProgressHUD() let checkoutURL = URL(string: url)! safariVC = SFSafariViewController(url: checkoutURL) safariVC.delegate = self self.present(safariVC, animated: true) } // Delegate method implementations func safariViewControllerDidFinish(_ controller: SFSafariViewController) { print("SafariViewController dismissed") // Handle dismissal } func safariViewController(_ controller: SFSafariViewController, initialLoadDidRedirectTo URL: URL) { print(URL.absoluteString) if URL.absoluteString.contains("xsworld/payment/stripe/checkout/success") { controller.dismiss(animated: true) { if URL.absoluteString.contains("/v1/resources/xsworld/payment/stripe/checkout") { NotificationCenter.default.post( name: Notification.Name("StripePaymentStatus"), object: nil, userInfo: ["url": URL] ) } } } else if URL.absoluteString.contains("xsworld/payment/stripe/checkout/cancel") { // Handle failure NotificationCenter.default.post( name: Notification.Name("StripePaymentStatus"), object: nil, userInfo: ["url": URL] ) } } func safariViewController(_ controller: SFSafariViewController, didCompleteInitialLoad didLoadSuccessfully: Bool) { if didLoadSuccessfully { print("Initial page loaded successfully") } else { print("Initial page load failed") } } Issue: The safariViewController(_:initialLoadDidRedirectTo:) method does not always get called after the payment is completed. Sometimes it works as expected, and sometimes it does not trigger at all. What I’ve Tried: Ensuring the associated domains for deep linking are correctly set up. Checking the success and failure URLs. Debugging to see if the redirect happens but is not detected. What I Need Help With: I want to ensure that the redirection always works after the payment process is completed, whether through deep linking or another reliable approach. How can I guarantee that my app correctly detects and handles the redirect every time? Any guidance or best practices would be greatly appreciated.

Throttling on navigator.geolocation.getCurrentPosition on Safari
I'm using navigator.geolocation.getCurrentPosition to retrieve the users coordinates in a PWA built with Nextjs. getCurrentPosition is called by clicking on a button. If getCurrentPosition is called afterwards, the cached value is returned. On Safari, If I refresh the page, or logout, login and call getCurrentPosition again, the getCurrentPosition error callback is called with an error code 2 - POSITION_UNAVAILABLE. After around five minutes, getCurrentPosition can be called again. Is there some kind of throttling restriction on Safari navigator.geolocation.getCurrentPosition?

Can I use allowFileAccessFromFileURLs to access local html file in my Project and not get appStorereview
We are currently implementing the payment flow, and for handling payment details — including card entry and validation — we are utilizing a WKWebView. The webview securely loads the payment provider’s page, ensuring sensitive information such as card numbers are entered and validated directly within the web context. I’d like to clarify that this change has not yet been released to Production. As part of a feature enhancement to our existing payment flow, we are transitioning to a new payment vendor, SnapPay. While trying to load the SnapPay URL embedded within an iFrame in our iOS app, I observed the following error in the Xcode console. While this error may be generic, I wanted to highlight it: 825a18 - [pageProxyID=7, webPageID=8, PID=67346] WebPageProxy::didFailLoadForFrame: frameID=24, isMainFrame=0, domain=NSURLErrorDomain, code=-999 Upon investigating, we compared the headers from our existing payment URL and SnapPay's URL, and found that SnapPay includes the following Content-Security-Policy (CSP) header: Content-Security-Policy: frame-ancestors ... "Content-Security-Policy" value="default-src 'self'; script-src 'self' https://hcaptcha.com https://.hcaptcha.com https://code.jquery.com https://www.gstatic.com https://code.jquery.com/jquery-3.3.1.min.js https://test.lightbox.cardx.com/v1/lightbox.min.js https://www.ssa.gov/accessibility/andi/ https://c.evidon.com 'unsafe-inline' 'unsafe-eval'; style-src 'self' https://hcaptcha.com https://.hcaptcha.com https://fonts.googleapis.com/css https://stage.snappayglobal.com/Resource/ https://www.ssa.gov/accessibility/andi/andi.css 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' *.googleapis.com *.gstatic.com ; connect-src 'self' https://demo1.cditechnology.com https:; form-action https://hcaptcha.com https: 'self' *.ipg-online.com secure.bluepay.com https://test.api.lightbox.cardx.com https://3ds-acs.test.modirum.com/ https://demo1.cditechnology.com/; frame-ancestors https://snappaydirect-perf.fiserv.com 'self' file: https: http; frame-src .snappayglobal.com 'self' https://hcaptcha.com https://.hcaptcha.com https: https://www.google.com .ipg-online.com secure.bluepay.com https://.cardconnect.com https://test.api.lightbox.cardx.com/ https://test.lightbox.cardx.com https://paywithcardx.com/payment/auth.cgi securepayments.cardpointe.com *.cardpointe.com https://3ds-acs.test.modirum.com/ https://www.yokohamatire.com http://uat1-txt.ad.portal.texas.gov https://uat1-txt.ad.portal.texas.gov " After multiple working sessions with the SnapPay team, we were able to confirm that when they disable CSP or remove the frame-ancestors directive, the iFrame loads successfully within our app. However, SnapPay cannot change on their CSP. To enable the iFrame to load in the iOS app, we added the following line of code: webView.configuration.preferences.setValue(true, forKey: "allowFileAccessFromFileURLs"). This resolved the issue with loading the iFrame. Note: the file being loaded is a local .html file,. Before submitting this update to the App Store, I’d like to confirm whether this usage of allowFileAccessFromFileURLs is acceptable for App Store review. I wanted to confirm that with this change is there a security concern for WKWebview?
