Inquiry about WebRTC camera access when using Chrome browser and WKWebView API on iPadOS
We are Java application developers and we have a question regarding camera access via WebRTC on iPadOS. Specifically, on iPadOS 17.1, we are encountering an issue when trying to access the camera via the WKWebView API in the Chrome browser, where an error occurs and the camera capture fails. Our investigation suggests that device access through the navigator.mediaDevices property via the WKWebView API may not work in Chrome. However, it works as expected in the Safari browser, leading us to wonder if this is a Chrome-specific limitation, or if it's due to an iPadOS setting or specification. At this point, we are unsure if this issue is related to the WKWebView and WebRTC specifications on iPadOS 17.1, or if there are specific limitations in Chrome. We would appreciate any insights or solutions regarding camera access in iPadOS 17.1 with WKWebView and WebRTC, especially in relation to Chrome.

Conditions and Specifications When Seamless App Launch via Universal Links Fails
**Description: ** We have implemented a process to launch a native app from a browser (Safari) via universal links. However, under certain conditions, the app does not launch seamlessly, and an error page is displayed in the browser. In such cases, a button to open the app appears at the top of the error page, and pressing this button successfully opens the app. The error page is a blank white page with only the following error message displayed: "NoSuchKeyThe specified key does not exist." We want to confirm the detailed specifications and conditions of the behavior where seamless transition via universal links fails. If there are means to suppress or control the occurrence of this issue, please let us know. Configuration: OS: iOS 18.1 Device: iPad 9th generation, 10th generation **Reproduction Steps: ** When attempting to launch the app via a universal link, a pop-up appears asking "Do you want to allow this page to open ?" If 'Cancel' is pressed in this pop-up, the issue occurs the next time the app is launched via a universal link. However, we have also confirmed that this issue can occur due to operations other than this one, and we have not been able to pinpoint the conditions under which it occurs. Therefore, we would like to confirm the detailed specifications and conditions leading to the occurrence of this 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.

PerApp VPN Broken on iOS 18.2 if Huge Safari Domains Configure?
When configuring a Per-App VPN payload with 250+ Safari domains under a managed app, the VPN does not trigger for the other managed apps(like chrome etc). However, the same VPN successfully starts and works when used with Safari. Reducing the number of Safari domains in the VPN payload resolves the issue, allowing the VPN to trigger for the managed app as expected. Has anyone else faced this issue, and what's the workaround for it?

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?

WKWebview termination due to memory. Adjustable threshold for termination?
Hi, Our company has an application uses the WKWebview to host a lot of content. The content is web based and hosts a lot of charts and metrics. Because of the high content, we've seen the memory of the WebContent hit above 1.25 GB. When that happens, it'll eventually terminate and we have our recovery code to reload the same page Seems like the limit is hidden / internal. Some Apple devs also noted something might be hard coded to be limited as well. Yes, we have our optimizations but we still need to keep our queries, use react, cache, etc... It's just a heavy web application. Request: Can you help us raise that limit? Are there some limitations in Webkit for such a need to terminate? As some devices have much higher RAM than before, we were hoping to be able to dynamically adjust the limit for the wkwebview before it resets. We contacted our internal contacts but they said to post here.

Apple Pay sometimes doesn't work (device specific)
Hey there. I recently completed an Apple Pay (on the web) integration and it has been working fine, for the most part. I had one customer contact us saying that it didn't work on his devices though. I checked it out, and while it does normally work (and we've had over a thousand transactions use it) there does seem to be some scenarios where it fails and I'm not sure why. I was able to replicate his issue (or at least an issue) by using BrowserStack. When I click the button which should initiate the payment, everything works in the JS code until it gets to the applePaySession.begin() function call. Once it hits that, it just stops. No errors are generated and no notice is given that anything is wrong until you try to do it a second time. Then an error about a payment session already being active on the page is thrown. I'm not really sure how to troubleshoot this since I know it works on my old iPad Air 2, my current M4 Macbook, multiple other devices, and also works when scanning the QR code for use on an iPhone. There is some very specific thing with some very specific versions of Safari that seem to be tripping it up. If it helps, the version of Safari on the BrowserStack device is 18.1, but the version on my Macbook is 18.1.1. The version the customer who is having the issue is on is 18.2 according to him. The customer also says they have used ApplePay on other websites with no issues. I checked one of them and they appear to be using a PayPal integration, where as I am using the ApplePay SDK straight from Apple. There are quite a few variables at play here, and I'm just trying to narrow down what I should be looking at. If one person is reporting the issue, there are probably others with it as well.

iOS 18.2 Can't open X-Callback-URL from Safari Extension
I have a Safari Extension which replaces default new tab and puts a link on a generated new tab. This link can be either usual URL link, or a URL Scheme, something like plecoapi://x-callback-url/df?hw=${char}&sec=dict In iOS 17 and previosly, this link worked flawlessly. In iOS 18, including 18.2, this X-Callback-URL link works only once, if I kill Safari process, reopen Safari and tap the link. Each subsequent tap will just reload the page, link won't work anymore until the next Safari reload. Usual URL links works every time without a problem.

Content blocker not removing content
I have a content blocker that generally works correctly, but I need to block an element that has certain text in it. For example, <span id="theId">Some text</span> is easy enough to block because I can locate the id and block that, but what if there is no id, or the id is completely random? What if it's just <span>Some text</span>? How do I block that? Let's say this is my only content blocker rule: [ { "action": { "type": "css-display-none", "selector": ":has-text(/Some text/i)" }, "trigger": { "url-filter": ".*" } } ] No errors are seen when the rule is loaded, so it's syntactically correct, it just doesn't block the HTML. I gather this is because :has-text() works on attributes, not contents, so it works on alt, href, aria-label etc. but not on the contents of the element itself. How do I block Some text in my example above? Thanks!

Issue with iOS Safari Handling Updates in .ics Files
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: BEGIN:VCALENDAR VERSION:2.0 CALSCALE:GREGORIAN PRODID:NAME BEGIN:VEVENT DTSTAMP:20250101T195917Z DTSTART:20250102T131600 DTEND:20250102T142500 SUMMARY:My Event 1 UID:unique-uid1 LAST-MODIFIED:20250101T155715Z DESCRIPTION:Description SEQUENCE:1 END:VEVENT BEGIN:VEVENT DTSTAMP:20250101T195917Z DTSTART:20250103T131600 DTEND:20250103T135600 SUMMARY:My Event 2 UID:unique-uid2 LAST-MODIFIED:20250101T155715Z DESCRIPTION:Description SEQUENCE:1 END:VEVENT END:VCALENDAR Later, I updated the .ics file with new event details: BEGIN:VCALENDAR VERSION:2.0 CALSCALE:GREGORIAN PRODID:NAME BEGIN:VEVENT DTSTAMP:20250102T195917Z DTSTART:20250104T131600 DTEND:20250104T142500 SUMMARY:My Event 1 Update UID:unique-uid1 LAST-MODIFIED:20250104T155715Z DESCRIPTION:Description SEQUENCE:2 END:VEVENT BEGIN:VEVENT DTSTAMP:20250102T195917Z DTSTART:20250105T131600 DTEND:20250105T142500 SUMMARY:My Event 2 Update UID:unique-uid2 LAST-MODIFIED:20250102T155715Z DESCRIPTION:Description SEQUENCE:2 END:VEVENT END:VCALENDAR 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!

Passwords autofill doesn't work for WKWebView in certain (but widespread) cases
When WKWebView loads a site that has username and password on different pages, standard "Passwords" button above keyboard does nothing. Reproducible on both physical device and simulator. At the same time, Safari works fine in this case. Any chance to fix this behavior in the upcoming iOS updates? Here's video demonstrating the issue: and a sample code to reproduce it (nothing specific, just bare WKWebView with default configuration): class ViewController: UIViewController { private let webView = WKWebView(frame: .zero) override func viewDidLoad() { super.viewDidLoad() view.addSubview(webView) } override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() webView.frame = view.bounds } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) webView.load(URLRequest( url: URL(string: "https://accounts.google.com/")! )) } }
