Observed versions: Reproduced on Tahoe / Safari 26 and iOS 26 Safari. Not reproduced on v18 Safari. Not reproduced in Chrome with the same reduced test setup. We are seeing a Safari-only rendering issue affecting an ad creative inside an iframe on both desktop Safari and iOS Safari. What we observe: The issue is reproducible in Safari on OS X and iOS v26. We do not reproduce it in Chrome with the same test setup. We can reproduce it in a minimal test case, outside our site app code. The issue appears tied to the rendered iframe document/layout, not our outer page layout. The problematic rendered structure inside the iframe looks like this: <div class="GoogleActiveViewElement" style="display:inline"> <ins class="dcmads" style="display:inline-block;width:320px;height:50px"> <script src="https://www.googletagservices.com/dcm/dcmads.js"></script> </ins> </div> Here is a simplified, local-reproducible version for testing: <div class="GoogleActiveViewInnerContainer" style="left:0px; top:0px; width:100%; height:100%; position:fixed; pointer-events:none; z-index:-9999;"></div> <div class="GoogleActiveViewElement" style="display:inline"> <ins class="dcmads" style="display:inline-block;width:320px;height:50px"> <script> document.write( '<a target="_blank" href="#"><img ' + 'src="data:image/svg+xml;utf8,' + encodeURIComponent( '<svg xmlns="http://www.w3.org/2000/svg" width="320" height="50">' + '<rect width="320" height="50" fill="#ffd8d8"/>' + '<text x="160" y="30" text-anchor="middle" font-family="Arial" font-size="14" fill="#222">' + 'img placeholder' + '</text>' + '</svg>' ) + '" ' + ' alt="Advertisement" border="0" width="320" height="50" style="display:block" /></a>' ); </script> </ins> </div> In Safari, this produces extra vertical spacing / cutoff above the ad. In the test code you will only notice an added top spacing, but when rendered in a live ad, the bottom gets cut off. A few details that may help: If we manually change the inner ins.dcmads from display:inline-block to display:inline, or adding overflow:hidden, the spacing issue goes away. If the loader script is moved outside the ins during manual experimentation, the issue also goes away. This makes it look like a Safari layout/rendering issue involving an inline wrapper around an inline-block ad container during script-driven rendering. Questions: Is this a known Safari/WebKit layout issue involving inline + inline-block content in iframe documents? Has there been any recent Safari/WebKit change that could affect this rendering path? Is there a preferred reduced repro format for reporting layout issues like this?

Background We are investigating Safari’s Prevent Cross‑Site Tracking feature (part of Intelligent Tracking Prevention / Link Tracking Protection) on iOS and macOS (latest versions). We fully understand and respect Safari’s privacy objectives and are not requesting any whitelisting or relaxation of protections. Our goal is to understand how Safari determines when and where query parameter stripping is applied, so we can design a compliant and predictable implementation. Based on public WebKit and privacy documentation, it is understood that Safari’s tracking prevention behavior may be influenced by: Tracker classification sources such as: DuckDuckGo Tracker Radar https://github.com/duckduckgo/tracker-radar EasyList / EasyPrivacy https://easylist.to/easylist/easyprivacy.txt WebKit privacy architecture and heuristics, including behavior described in: WebKit “Private Browsing 2.0” / Link Tracking Protection documentation https://webkit.org/blog/15697/private-browsing-2-0/ Request for Guidance To help us align fully with Safari’s privacy model, we respectfully request guidance on: How Safari determines, at a domain or subdomain level, when to apply query parameter stripping under Prevent Cross‑Site Tracking. Whether evaluation may be influenced by: Tracker classification sources (e.g., domain reputation or known tracking endpoints) Runtime network behavior (such as cross‑site analytics requests) Subdomain‑specific context or historical behavior Whether Prevent Cross‑Site Tracking is evaluated: Per navigation event Per domain or subdomain Based on cumulative or runtime signals Whether Apple recommends specific design patterns or alternatives for handling essential, non‑tracking URL data in a way that is compatible with Safari’s privacy protections. Our objective is to design a solution that respects Safari’s intent and avoids reliance on fragile or unpredictable URL‑based behavior.

Hi team, may I know how I can access the report for the Safari Smart App Banner here please? We want to know how many people taps to views or install the app from that specific banner. Please advise on this. Thank you.

I want to build a WebKit website, specifically for AI coding. Is there a custom code design or application code for this? I've already implemented a few SEO optimizations on my homepage. Could you please check and reply? seokurdu.com

I'm unclear on the implications of Apple's App Review Guideline 5.2.2: If your app uses, accesses, monetizes access to, or displays content from a third-party service, ensure that you are specifically permitted to do so under the service’s terms of use. Authorization must be provided upon request. If a paid subscription app uses a licensed search API to retrieve and display links to publicly available third-party web content, is the API license generally enough for compliance? Or does Apple expect separate authorization from each underlying website whose content appears in the search results?

Hello All, I have a app which has a WKWebview loading some code from a remote origin - https://my-company.example.com When WKWebview loads remote origin, that page does load some of the sub-resources from in-app localhost server (GCDWebserver), i.e. reach out to a loopback based in-app GCDWebserver, now to provide a secure context I had an existing setup with self signed cert, CORS and everything needed for https on localhost. And the sub-resources used to load fine from https localhost till 26.4 Starting with iOS 26.4 it started breaking with TLSv1_ALERT_UNKNOWN_CA Is there any known guidance for this? Technically as per w3c spec, localhost is considered secure context by default right? and no special things need to be done. But ios/Webkit seem to be different in this regard. Is this a known issue, and is there any mitigation here? I'll try to provide a sample app soon if possible.

There does not appear to be any way to use or create iCloud passkeys with a Safari Web Extension, either using the navigator.credentials API in an extension origin webpage such as the popover, or using the AuthenticationServices framework in the SafariWebExtensionHandler. I've setup an associated domain for my plugin, and I know it works for the host application. But I get errors trying to do so in the web extension target. createCredentialRegistrationRequests results in the following error: Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "Application with identifier <ID> is not associated with domain <RPID> The other problem, assuming the entitlement works correctly for the web extension, is that there is no NSWindow to use as the presentation target from the SafariWebExtensionHandler. Trying to use the navigator.credentials.create JS API (which is the preferred method, frankly, in a web extension) results in the following error: NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission. Chrome has a great solution for this that I believe should be adopted by Safari. If an extension has host permissions for a relying party it wants to claim, or if it has an associated domain entitlement for it, webauthn operations should be allowed.

Safari on iOS 17, when entering characters into text input box after deleting characters, the layout is off. Here's the HTML: <body> <div id="J001" style="display: inline-block;"> <div id="J001__0" style="display: inline-block;"> <input id="J001__0__input" style="display: inline-block; height: 28px; padding:2px; border:1px solid gray;"></div> <div id="J003__0" style="display: inline-block;"> <button id="J003__0__btn" style="display: inline-block; height:34px;">a</button> </div> </div> </body> Enter "A" into text input box. Delete "A" with the backspace(x). Enter "A" into text input box, the button position will be shifted down. iOS 17 の Safari にて、テキスト入力ボックスで文字を削除した後、文字を入力するとレイアウトが崩れます。 テキスト入力ボックスに「A」と入力します。 バックスペース(x)で「A」を削除します。 テキスト入力ボックスに「A」と入力すると、ボタンの位置が下にずれます。

The title says it all, and I've filed FB FB22353950 that includes an Xcode 26.4 Screen Saver test project, QT movie demonstrating the error, and a PDF with complete steps to build and test. I'm asking here just to learn if this sounds familiar. The SS built on 26.4 fails in 26.4, works fine on 26.3.1. I'll supply the test files if there's interest. Thanks.

I would like to script my Mac to close a specific iCloud Tab of my choice that is open on my iPhone. This is for Accessibility reasons. Ideally, I’d prefer to do this without using GUI scripting. AppleScript methods only seem to see tabs in Windows Extensions also do not seem to have visibility of the other types of tabs I've tried many options so far, but all seem to not work and are also far too brittle even if they did. I have a feeling I'm missing something! 1. Toolbar Dropdown In Desktop Safari you can enable a toolbar button “iCloud Tabs” which when clicked shows a list of the tabs currently open on your other devices. If you hover one, an X appears which can be clicked to close the tab. When you next use Safari on the remote device that tab will be closed. If it’s already open and awake then the removal happens around one second later. It’s quick. (But I did try GUI scripting and I can get to the row in the outline in the popup, but I can’t get the cross to appear to click it) 2. Start Page they’re also listed on favorites:// “start page” but there are issues viewing all and no way to search them. There used to be a search field until Safari ~15. 3. Omnibar They’re also shown in omni/address bar, but getting the correct item to appear at all or in a predictable position is fragile. 4. Sidebar Another alternative to the favorites/"start page" layout. Same issues. 5. Modifying Safari Database directly Changes are not mirrored to the cloud. It seems Safari does a cloudd request that I can't do.

We are experiencing an issue after Xcode 26.0 to load local javascript files to WKWebView to render our own design. it used to work well, however after Xcode 26.0, when [self.webView loadFileURL:fileURL allowingReadAccessToURL:accessURL]; it returns [PID=1514] WebProcessProxy::hasAssumedReadAccessToURL(3198190): no access self.webRootPath = [[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:CHAT_VIEW_WEB_ROOT]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSError *error = nil; if (!

Any help much appreciated.

According to our crash analytics, our application crashes while a context menu is opened on a web view. This crash takes place on iOS 26+ only. The messages states that a web view is no longer inside active window hierarchy, however we doesn't modify web view instance's parent anyhow while the context menu is opened. Can you please help with a fix or at least workaround for this issue? What's your opinion for bug localization (application or framework)?

We're developing a service that requires webtransport support in the browser. Currently, the only browser that doesn't provide support is the IOS version of Safari. Our current way forward for client use is to flag iphone and ipad as non compliant and recommend either desktop use or android. Is there any ballpark date as to when WebTransport will be included in IOS Safari (- webkit supports webtransport)?

I'm building a Capacitor iOS app with a plain <video> element playing an MP4 file inline. I want Picture-in-Picture to activate automatically when the user goes home — swipe up from the bottom edge of the screen (on an iPhone with Face ID) or press the Home button (on an iPhone with a Home button). Fullscreen → background works perfectly — iOS automatically enters Picture-in-Picture. But I need this to work from inline playback without requiring the user to enter fullscreen first. Setup <video id="video" playsinline autopictureinpicture controls src="http://podcasts.apple.com/resources/462787156.mp4"> </video> // AppDelegate.swift let audioSession = AVAudioSession.sharedInstance() try? audioSession.setCategory(.playback, mode: .moviePlayback) try? audioSession.setActive(true) UIBackgroundModes: audio in Info.plist allowsPictureInPictureMediaPlayback is true (Apple default) iOS 26.3.1, WKWebView via Capacitor What I've tried 1. autopictureinpicture attribute <video playsinline autopictureinpicture ...> WKWebView doesn't honor this attribute from inline playback. It only works when transitioning from fullscreen. 2. requestPictureInPicture() on visibilitychange document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'hidden' && !video.paused) { video.requestPictureInPicture(); } }); Result: Fails with "not triggered by user activation". The visibilitychange event doesn't count as a user gesture. 3. webkitSetPresentationMode('picture-in-picture') on visibilitychange document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'hidden' && !video.paused) { video.webkitSetPresentationMode('picture-in-picture'); } }); Result: No error thrown. The webkitpresentationmodechanged event fires with value picture-in-picture. But the PIP window never actually appears. The API silently accepts the call but nothing renders. 4. await play() then webkitSetPresentationMode document.addEventListener('visibilitychange', async () => { if (document.visibilityState === 'hidden') { await video.play(); video.webkitSetPresentationMode('picture-in-picture'); } }); Result: play() succeeds (audio resumes in background), but PIP still doesn't open. 5. Auto-resume on system pause + PIP on visibilitychange iOS fires pause before visibilitychange when backgrounding. I tried resuming in the pause handler, then requesting PIP in visibilitychange: video.addEventListener('pause', () => { if (document.visibilityState === 'hidden') { video.play(); // auto-resume } }); document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'hidden' && !video.paused) { video.webkitSetPresentationMode('picture-in-picture'); } }); Result: Audio resumes successfully, but PIP still doesn't open. 6. Native JS eval from applicationDidEnterBackground func applicationDidEnterBackground(_ application: UIApplication) { webView?.evaluateJavaScript( "document.querySelector('video').requestPictureInPicture()" ) } Result: Same failure — no user activation context. Observations The event order on background is: pause → visibility: hidden webkitSetPresentationMode reports success (event fires, no error) but the PIP window never renders requestPictureInPicture() consistently requires user activation, even from native JS eval Audio can be resumed in background via play(), but PIP is a separate gate Fullscreen → background automatically enters Picture-in-Picture, confirming the WKWebView PIP infrastructure is functional Question Is there any way to programmatically enter PIP from inline playback when a WKWebView app goes to background? Or is this intentionally restricted by WebKit to fullscreen-only transitions? Any pointers appreciated. Thanks!

Reporting a consistent system-wide freeze followed by a Kernel Panic when attempting to use the "Add to Home Screen" feature in Safari. This issue has persisted across multiple recent iOS updates and leads to a device bootloop. Technical Details: The UI becomes entirely unresponsive for exactly 180 seconds. Analytics logs indicate a userspace watchdog timeout caused by SpringBoard failing to check in. Panic String: panic(cpu 0 caller 0xffffffff0422ccb9): userspace watchdog timeout: no successful checkins from SpringBoard (0 induced crashes) in 180 seconds Steps to Reproduce: Open Safari and navigate to any URL. Tap the Share icon. Select Add to Home Screen. The device UI freezes immediately. After 3 minutes, the system triggers a reboot. Environment: • Device: 16PM panic-base-2026-03-12-222721.ips.txt • OS Version: 26.4 RC and Beta 3 v1 • Feedback ID: FB22286846 (Full sysdiagnose and panic logs are attached to the original Feedback Assistant report). Questions: Is this a known regression involving the web clip background daemon, or does the 180s timeout suggest a specific database corruption within the Home Screen layout?

Summary When an app is associated with a domain via applinks in the Apple App Site Association (AASA) file, the app's icon is displayed next to passkey entries in the iOS passkey selection UI (e.g., in Safari's sign-in dialog). This occurs even when: The AASA file does not contain a webcredentials section The passkey's relying party ID (rp.id) matches the domain, but the app has no webcredentials association The URL path of the passkey login page does not match any paths specified in the applinks configuration Environment iOS 18.6.2 iPhone 16 Pro Safari / Passkey UI via WebAuthn Steps to Reproduce Create an iOS app and register it in App Store Connect (or distribute via TestFlight) Configure the AASA file on the domain with only applinks — no webcredentials section: json{ "applinks": { "apps": [], "details": [ { "appIDs": ["TEAMID.com.example.myapp"], "components": [ { "/": "/specific-path/*" } ] } ] } } Implement WebAuthn/passkey registration on the same domain with the domain as rp.id Install the app on the device (via TestFlight or App Store) Register a passkey on the website via Safari Navigate to the login page and trigger the passkey selection UI Expected Behavior Since webcredentials is not configured in the AASA file, the passkey selection UI should NOT display the app icon next to the passkey entry. The passkey icon should be the default website favicon or a generic icon. Actual Behavior The app icon (from App Store Connect / TestFlight) is displayed next to the passkey entry in the selection UI, even though: Only applinks is configured (no webcredentials) The current page URL does not match any paths in the applinks configuration Impact In our production environment, we have a single domain serving multiple partner bank apps. The AASA file contains applinks entries for many different apps (20+ partner apps). When a user accesses the passkey login page, the passkey UI may display an app icon from one of these partner apps, which can be confusing for users — especially if the displayed icon belongs to a different partner's app than the one the user intends to use. Questions Is this the intended behavior — that applinks associations influence the passkey UI icon display? Is there a way to prevent applinks associations from affecting the passkey selection UI without removing the applinks entries? Would adding a proper webcredentials section with the correct app ID override the icon source from applinks to webcredentials? Is there a recommended approach for domains that serve multiple apps via applinks but want to control which icon appears in the passkey UI?

Hi, I'm having difficulties fetching many 2 many relationships. I have an Actor entity (which I can query in CloudKit JS) that has 2 relationships: inputComponents and outputComponents, both pointing towards a Component entity. How to query these relationships? Thanks Tom

We are currently supporting an Apple Pay-enabled card program as an issuer/issuer processor and have successfully completed In-App Push Provisioning integration within our iOS application. The in-app flow is fully operational, including issuer-side cryptographic exchange and Mastercard MDES network tokenization. We are now looking to extend this integration to support Apple Pay Web Push Provisioning, allowing cardholders to add eligible cards to Apple Wallet directly from our web application. We would appreciate guidance on: -The process for enrolling in Apple Business Register (if required) -Enabling Web Push Provisioning for an issuer profile Required entitlements or provisioning certificates Any additional onboarding steps specific to issuer-level Web provisioning We understand that Web Push Provisioning requires issuer-level enablement beyond standard Apple Pay on the Web, and we would like clarification on the correct path to activate this capability. Thank you in advance for your guidance.

When setting the language in iOS/macOS to German (or other languages with “,” decimal separator) and number format to “1.234.567,89” in iOS 26.2, 26.3 and 26.4 Beta, Safari inserts the wrong decimal separator in elements. It should use the local German decimal separator comma “,” instead it uses the english/international period “.” Here is a screenshot of iOS 26.2 when visiting a website with just 2 number inputs in Safari: <input type="number"> <input type="number" value="5.6"> It behaves the following way: On the first input, enter a number with decimals like “12,34”, clicking “,” on the onscreen-keyboard, a “.” instead of a “,” is added. The number then is formatted in international/English: “12.34”. The input set programatically shows the right decimal separator for German: "5,6". But deleting the “,” and pressing “,” on the onscreen-keyboard again adds a dot instead of a comma and shows the number in international/english: “5.6”. The same issue also happens on desktop Safari on MacOS 26.2 and newer and iOS apps using webviews, also since iOS 26.2. How to use the correct decimal separator in html number inputs for the user selected language in iOS/macOS on iOS 26.2 and newer versions? Is this maybe a bug? This was working correctly for iOS 26.1 and older:
