Hello everyone, I'm working on an app that uses WKWebView. My app uses a custom menu and we disable the default menu by overriding with: WKWebAction.canPerformAction() However, with the new iOS 18.2 release, I am no longer able to override the "Copy Link with Highlight" option that pops up when highlighting a selection as can be seen from the screenshot: Has anyone found a work around/bypass for this? Environment iOS Version: iOS 18.2 Device: iPhone 13 Pro App platform: iOS Xcode version: 16.1 MacOS: 14.5

The extension popups don't seem to support the dark mode media query. The only way the query gets detected is when a color-scheme is added: <meta name="color-scheme"content="light dark">

The crash is specific to iOS 26.2 prior versions working fine. WKScriptMessageHandler delegate func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) Name attribute is accessible but WKScriptMessage body attribute causes crash The object seems to be not accessible(not in memory) self.webkit.configuration.userContentController.add(self, name: "sampleHandler") self.webkit.load(request) func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) { print(message.name) // works print(message.body) // crashes }

I am reporting what appears to be a serious integrity flaw in Safari under iPadOS 26.3 (and lower) that materially undermines the reliability of Screen Time parental controls. This is not merely a UX inconsistency but a functional contradiction within a system explicitly marketed and positioned as secure parental control infrastructure. Device / Environment Device: iPad Air M3 13" (2025) OS: iPadOS 26.3 Safari (system version) Screen Time enabled with active restrictions Child account (10 years old) Background We deliberately chose an Apple device for school use based on the expectation that Apple’s system-level parental control mechanisms — especially Screen Time — are robust, tamper-resistant, and technically consistent. Screen Time is configured with: App limits Downtime Parental controls enabled with limited web content restrictions (school requirements prevent strict blocking) Safari enabled (mandatory for educational use) further parental control restrictions Because aggressive website blocking would interfere with legitimate school activities, monitoring Safari browsing history is a central supervisory mechanism. When Screen Time is active: Clearing the entire browsing history via Safari is correctly blocked. Clearing history via system settings is correctly blocked. The system explicitly communicates that deletion is not permitted due to Screen Time restrictions. This behavior establishes a clear user expectation: Browsing history is protected against manipulation. The Issue Despite the above safeguards, individual browsing history entries can be deleted easily and silently through the address bar suggestion interface. This creates a structural contradiction: Full deletion is blocked. Selective deletion — which is arguably more problematic — remains possible. Steps to Reproduce Enable Screen Time with restrictions that prevent deletion of browsing history (for example on a student device with a child account). Open Safari and visit any website. Confirm it appears in Safari history. Tap the Safari address bar. Type part of the URL or page title. Safari suggests the previously visited page below the address bar. Swipe left on that suggestion. A red “Delete from History” button appears. Tap it. Actual Result The entry disappears immediately: No Screen Time PIN required No authentication request No warning No restriction triggered No parental notification No audit trace visible Deletion occurs silently and irreversibly. Expected Result When Screen Time is configured to prevent browsing history deletion: Individual entries must not be deletable Deletion must require Screen Time authentication Anything else defeats the protective purpose of the restriction. Real-World Impact In practical use, this allows minors to selectively sanitize browsing history while preserving a seemingly intact record. In our case, this method is widely known among classmates and routinely used to conceal visits to gaming or social media platforms during school hours. The technical barrier to exploitation is negligible. This results in: A false sense of security for parents A discrepancy between advertised functionality and actual system behavior A material weakening of parental control integrity When a system explicitly blocks full history deletion but permits silent selective deletion, the protection mechanism becomes functionally inconsistent and unreliable. Given that Screen Time is publicly positioned as a dependable parental control framework, this issue raises concerns not only about implementation quality but also about user trust and reasonable reliance on advertised safeguards. Request Please classify this as a parental control integrity and trust issue. Specifically: Disable individual history deletion while Screen Time restrictions are active OR Require Screen Time passcode authentication for deleting single entries Screen Time is presented as a secure supervisory environment for minors. In its current implementation under iPadOS 26.3 and before, that expectation is technically not met. This issue warrants prioritization.

Is the new Observations API for WebPage not available in Beta 1 as demoed in the WWDC video? I get this error even though Observation is imported.

Hi, after upgrading MacOS (MB Air M1 Version 26.2 (25C56)) & Safari (Version 26.2 (21623.1.14.11.9)) to latest versions, we are experiencing a new bug occurring with our web extension (Click & Read) on local storage writing and getting this error : Invalid call to browser.storage.local.set(). Disk I/O error. This doesn't happen on other browsers (chromium, Firefox). export const setLocalStorage = async (value: object) => { try { await browser.storage.local.set(value); } catch (error) { console.error("[Click & Read] Error setting local storage", error); } };

Hello, I am developing a Mac application via Mac Catalyst and encountering an issue with WKWebView. Specifically, I'm loading a webpage (e.g., https://translate.google.com) in WKWebView, but when I press the copy button on the page, the content doesn't actually copy to the clipboard. I've attempted modifying the UserAgent without any success. Here is the relevant part of my code: override func viewDidLoad() { super.viewDidLoad() let config = WKWebViewConfiguration() config.preferences = WKPreferences() config.defaultWebpagePreferences.preferredContentMode = .desktop let webView = WKWebView(frame: .zero, configuration: config) webView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(webView) webView.scrollView.showsVerticalScrollIndicator = false webView.backgroundColor = UIColor.white webView.scrollView.backgroundColor = UIColor.white webView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true webView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true webView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true webView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true if let url = URL(string: "https://translate.google.com") { let req = URLRequest(url: url) webView.load(req) } }

From a mail app or similar, when opening a webpage in Safari as an external browser, JavaScript on the webpage stops running if Safari goes into the background. Is there a way to prevent this from happening? Sample code for the counter: Behavior: Upon returning from the background, the counter continues for about 7-8 seconds but does not progress further. For example, if Safari is kept in the background for about 20 seconds and then brought back, the counter stops at around 7-8 seconds and only resumes counting after returning to the foreground. Expectation: The counter should continue running even if Safari goes into the background.

Starting with iOS 26.2, when Safari tabs are set to Bottom or Compact view, some pages are not rendering properly. The error does not occur in Top view. For some pages, scrolling causes rendering to be very slow, causing the user to experience page breaks and missing parts. If the user waits a few seconds, the missing parts of the page will appear, but the issue will reoccur when scrolling further. We have tested this on all available iOS devices and the issue occurs on all iPhones running iOS 26.2. The issue does not occur on iOS 26.1, and we have not experienced it on devices running iOS 18. The issue can be reproduced on the following pages with an iPhone running iOS 26.2: https://fotosakademia.hu/products/course/fotografia-kozephaladoknak-haladoknak https://oktatas.kurzusguru.hu/products/course/az-online-kurzuskeszites-alapjai

I'm a web developer of WebRTC based web app for video and audio calls. After updating to iOS 26.1 beta I noticed, that my app can't use microphone anymore. When I'm calling to getUserMedia with audio set to true, Safari returns error "No AVAudioSessionCaptureDevice device". Other WebRTC demo apps also can't access microphone on this firmware. And maybe it's connected somehow, but safari can't detect connected AirPods Pro 2 as an input device. So, this bug brakes any WebRTC app, that uses microphones.

Hi, We are facing a major issue with our application. We are using FolioReaderkit to read epub files. Currently, it's working on the iOS 18.1 device and simulator, but it's not working on the iOS 18.2 and later version devices. we are facing this error in Folioreaderkit

I am trying to setup web sign in with apple, I have an active apple subscription and have set up all necessary things. I made a service id in apple Identifiers, connected to existing primary id (also has apple sign in enabled). I have my domain set up also correctly but still I cant generate the code due to invalid client. What do I need to do? I have also tried recreating the service ids multiple times with no luck. my init is AppleID.auth.init({ clientId : '[CLIENT_ID]',//used the service id one not app id redirectURI : '[REDIRECT_URI]', usePopup : true }); link to generate codes now is: https://appleid.apple.com/auth/authorize?client_id=com.crmtournest.sigin&redirect_uri=https%3A%2F%2Fwww.tournestcrm.com%2Fauth%2Fcallback&response_type=code%20id_token&state=saciy7rn1km&scope=name%20email&response_mode=web_message&frame_id=03487c22-abb4-48cd-8613-d6bf5836e9eb&m=11&v=1.5.5 Also tried: https://appleid.apple.com/auth/authorize?client_id=com.crmtournest.sigin&redirect_uri=https%3A%2F%2Fwww.tournestcrm.com%2Fauth%2Fcallback&response_type=code%20id_token (not working) I get invalid_client setup on apple below:

I’m experiencing a crash in WKWebView on iOS 26 Developer Beta 5 and Beta 6 with the following exception: CALayer position contains NaN: [nan 65] The crash occurs when the following CSS properties are applied to content displayed in WKWebView: -webkit-user-select: none; -webkit-touch-callout: none; This issue happens consistently whenever these styles are set, leading to the crash inside WKWebView. Is this a known bug in the current iOS 26 betas, or is there a recommended workaround?

I am encountering an intermittent issue with WKWebView in my iOS app. The problem occurs infrequently, but when it does, the WKWebView consistently displays a white screen and remains in this state until the app is forcefully terminated and relaunched. To provide more context, here are the key characteristics of the issue: The white screen problem occurs sporadically and is not easily reproducible. The WKWebView remains unresponsive despite attempts to interact with it. Reloading the webpage or navigating to a different URL does not resolve the white screen issue. The problem persists until the app is terminated and relaunched. This issue is specific to the WKWebView; other components of the app function correctly. The WKWebView renders normally, and the main document synchronously loads resources both offline and online without any issues. The bridge and JavaScript execution also work as expected. However, when interacting with the WKWebView, it becomes unresponsive to user clicks, and the web inspector fails to respond. Additionally, asynchronous network requests also do not receive any response. The problem occurs exclusively on HTTPS pages, whereas HTTP pages load without any issues. Other components, such as workers, function correctly. addUserScript injection during WKWebView creation is effective, and evaluateJavaScript during the page loading process works as expected. However, when the document becomes unresponsive, executing evaluateJavaScript only triggers the callback after the WKWebView is destroyed. I have discovered a reliable method to reproduce the white screen issue in WKWebView. This method involves the following steps and conditions: Create a WKWebView instance. Load an HTML page using the loadRequest method（https url request）. Before the WKWebView is attached to the UI (not yet visible to the user), call the evaluateJavaScript function. This issue has occurred in almost all iOS versions, including the latest iOS 17.x version.

The passkey authentication dialog appears, and after unlocking with Touch ID, the dialog closes without any notification of success or failure. This issue occurs with high frequency. access to the https://passkeys-demo.appspot.com/ register account and create passkey. logoff access to the url again you can see the passkey dialog unlock device then the dialog disappears nothing happens reload the page proceed 5) to 6) nothing happens or success webauthn.

Hi Apple engineers! We are making an iOS browser and are planing to deliver a feature that allows enterprise customers to use a MAM key to set a PAC file for proxy. It's designed to support unmanaged device so the MDM based solutions like 'Global HTTP Proxy MDM payload' or 'Per-App VPN' simply don't work. After doing some research we found that with WKWebView, the only framework allowed on iOS for web browsing, there's no API for programmatically setting proxy. The closes API is the WKURLSchemeHandler, but it's for data management not network request interception, in other word it can not be used to handle HTTP/HTTPS request well. When we go from the web-view level to the app level, it seems there's no API to let an app set proxy for itself at an app-level, the closest API is Per-App VPN but as mentioned above, Per-App VPN is only available for managed device so we can't use that as well. Eventually we go to the system level, and try to use Network Extension, but there's still obstacles. It seems Network Extension doesn't directly provide a way to write system proxy. In order to archive that, we may have to use Packet Tunnel Provider in destination IP mode and create a local VPN server to loop back the network traffic and do the proxy stuff in that server. In other word, the custom VPN protocol is 'forward directly without encryption'. This approach looks viable as we see some of the network analysis tools use this approach, but still I'd like to ask is this against App Store Review Guidelines? If the above approach with Network Extension is not against App Store Review Guidelines, I have a further question that, what is the NEProxySettings of NETunnelNetworkSettings for? Is it the proxy which proxies the VPN traffic (in order to hide source IP from VPN provider) or it is the proxy to use after network traffic goes into the virtual private network? If none of the above is considered recommended, what is the recommended way to programmatically set proxy on WKWebView on an unmanaged device (regardless of where the proxy runs, web-view/app/system)?

I'm working on a web browser App that's distributed via the App Store. This app renders web pages using WKWebView. Our users are requesting a way for us to allow them to play videos in Picture in Picture. After some investigation, we noticed that in order to allow PiP videos in our browser in the sandboxed environment, we need to add the com.apple.PIPAgent entitlement under the com.apple.security.temporary-exception.mach-lookup.global-name option. We tried to submit our app with this entitlement, but unfortunately, we were rejected: Guideline 2.4.50) - Performance We've determined that one or more temporary entitlement exceptions requested for this app are not appropriate and will not be granted: com.apple.security.temporary-exception.mach-lookup.global-name com.apple.P|PAgent We would like to have access to this entitlement so we can offer PiP to our users. We already created a radar about this as well: FB13814428 Additionally, we have another radar (FB13557716) regarding allowing the usage of a private flag _allowsPictureInPictureMediaPlayback, which would also be required to enable us to use PiP. Is there any way in which we can currently enable PiP? Would opening a TSI help here?
