Face ID / Touch ID is requested twice when using Passkey Autofill
When using iCloud Keychain passkeys with WebAuthn (mediation: "conditional") in non-Safari browsers (e.g. Chrome or WKWebView-based browsers), Face ID / Touch ID is requested twice during Passkey Autofill. This issue occurs only when the focused input field shows a numeric keypad–style keyboard, such as: Japanese Kana Chinese Zhuyin With a standard QWERTY keyboard, authentication completes with a single user verification. Notably: Safari completes authentication with one Face ID / Touch ID prompt even with numeric keypad keyboards. Other browsers require two prompts. The issue does not occur with other credential managers (Google Password Manager, 1Password), suggesting this is specific to iCloud Keychain. This issue has been confirmed on the following OS versions: iOS 17.6.1 iOS 18.7.2 iOS 26.2 iOS 26.3 beta Impact This behavior results in a confusing and unintuitive login experience for users relying on Passkey Autofill. Steps to Reproduce: Go to Settings → Keyboards → Keyboards, and set “Japanese – Kana” as the primary keyboard. Enable Face ID / Touch ID, and make sure “Use Face ID / Touch ID For” → “Password Autofill” is enabled. Open Chrome and navigate to https://webauthn.io. Enter a username and tap “Register” to create a passkey using iCloud Keychain. Tap the username field again so that the “Japanese – Kana” keyboard appears and the passkey suggestion created in step 4 is shown. Tap the passkey suggestion. Face ID / Touch ID is requested twice. === This issue has already been reported via Feedback Assistant as FB21726047. I am posting here to confirm whether this behavior is working as intended or represents a bug, and to make other developers aware of the current behavior.

Voice Control evaluation questions: "Stop Recording" command failure & Item numbers on non-interactive web elements
Hello everyone, I am currently evaluating my app's accessibility features to accurately display the "Accessibility" information on the App Store. I have encountered two specific issues regarding Voice Control testing and would appreciate any guidance. Voice Command for "Stop Recording" According to the evaluation criteria, if an app supports audio recording or dictation, users must be able to start and stop recording using only their voice. Behavior: I can successfully trigger the recording using the command "Start Recording". However, I cannot find a command to stop it. Commands like "Stop Recording" or "Stop" are not recognized by the system. Question: Is there a specific standard voice command intended for stopping a recording? Item Number Overlays on Non-Interactive Web Elements (WKWebView) I noticed an inconsistency between native views and web content regarding Voice Control item numbering. Behavior: When testing web content within the app (WKWebView) or in Safari, Voice Control displays item number overlays on non-interactive text elements (such as standard or tags). In native views, static labels do not receive item numbers. Question: Is this expected behavior for web content? Since these elements are not interactive, I am unsure if this should be considered a bug (fail) or an acceptable exception for the accessibility evaluation. Has anyone experienced similar issues or know the correct criteria for these cases? Thank you.

`PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable()` returns false in non-Safari browsers on iOS 26.2+
There appears to be a regression or restriction in iOS 26.2 and 26.2.1 regarding the Web Authentication API in third-party browsers (browsers other than Safari). Specifically, the method PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable() returns false when called from within non-Safari browsers (e.g., Chrome, Firefox, Edge) on iOS, even when the device supports biometrics (FaceID/TouchID) and Passkeys are enabled. This prevents third-party browsers from correctly detecting Platform Authenticator availability, leading websites to hide Passkey login options or default to cross-device authentication flows instead of using the local device's biometric authenticator. Environment: OS: iOS 26.2, iOS 26.2.1 Device: iPhone 17 Browsers Tested: Chrome iOS and Firefox iOS Steps to Reproduce: Launch Safari on an iOS device running iOS 26.2+. Navigate to https://www.passkeys-debugger.io/. Observe that "Platform Auth" is highlighted in Green (true), indicating the device is eligible for passkey authentication. Launch a non-Safari browser (e.g., Chrome or Firefox) on the same device. Navigate to https://www.passkeys-debugger.io/. Expected Results: "Platform Auth" should be Green (true), matching the behavior in Safari, as the device possesses a built-in platform authenticator. Actual Results: "Platform Auth" is highlighted in Red (false). Impact: This discrepancy fragments the Passkey user experience on iOS. Users preferring third-party browsers are unable to utilize the seamless on-device biometric authentication that is available in Safari. It forces developers to implement complex fallbacks or results in users believing their device is incompatible with Passkeys.

Browser window with URL not opening via ASWebAuth
Our app uses ASWebAuthenticationSession for login. This launches an incognito (ephemeral) browser window of the system’s default browser with the authentication URL. Recently, on the latest macOS Tahoe, we observe that: The browser application is launched(we could see in the dock) But the authentication window with the URL does not appear No error is returned to the app (silent failure)

WebView Exit fullscreen issue on iPadOS
This demonstrates an issue with SwiftUI's WebView on iPadOS. To repro, testing on iPad Simulator OS 26.2, macOS 26.2, Xcode 26.2. Download and unzip this project: https://drive.google.com/file/d/1z3MobjDf_RvvOtriXtinXvrJ7rGHwZRs/view?usp=share_link Set up Signing and Run the swiftui-webview App target on simulator (I'm using iPad Pro 13-inch (M5 simulator) Tap/click the fullscreen [ ] button in the bottom left corner of the webpage. Tap/click the 'X' button in the top left, to exit fullscreen. Result: The WebView exits fullscreen, but there is no content loaded, just a white background. It's also now not possible to visit other URLs - the WebView appears to be unresponsive and not repaint. This does not appear to affect macOS 26.2, just iPadOS.

SwiftUI WebView: Is action.target == nil a Reliable Way to Handle New Window Requests?
In WKWebView, there is the WKUIDelegate method: func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {} This delegate method provides a callback when a new window (for example, target="_blank") is requested in the web view. However, in native SwiftUI (iOS 26), WebView / WebPage APIs do not provide an equivalent delegate method to handle new window requests. As a workaround, I am using the following method: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy {} In this method, when action.target == nil, I treat it as a new window request. My question: Is relying on action.target == nil in decidePolicy a reliable and future-safe way to detect new window requests in SwiftUI’s WebView, or is there a better or more recommended approach for handling target="_blank" / new window navigation in the SwiftUI WebView APIs? Code: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy { guard let webPage = webPage else { return .cancel } // Handle case where target frame is nil (e.g., target="_blank" or window.open) // This indicates a new window request if action.target == nil { print("Target frame is nil - new window requested") // WORKAROUND: Until iOS 26 WebPage UI protocol is available, we handle new windows here // Try to create a new WebPage through UI plugins if handleCreateWebPage(for: webPage, navigationAction: action) != nil { // Note: The new WebPage has been created and published to the view return .allow } } return .allow }

Build version upload failed
90809: Deprecated API Usage. New apps that use UIWebView are no longer accepted. Instead, use WKWebView for improved security and reliability. Learn more (https://developer.apple.com/documentation/uikit/uiwebview). I did not actively use UIWebView in my app, but this error occurred during the build upload process. This version has an additional integration of the iOS Ayla SDK and Public-9.0.7 SDK compared to the previous version. If there is indeed a call in a third-party SDK, how can I determine where the call exists? Thank you

File Download Support in SwiftUI Native WebView (iOS 26+)
I am using the native SwiftUI WebView and WebPage APIs (iOS 26+) and would like to implement file download functionality using the native SwiftUI WebView. However, I have not been able to find any APIs equivalent to WKDownload. In WKWebView, the WKDownload API can be used to handle downloads. I am looking for a similar API or recommended approach in the native SwiftUI WebView that would allow downloading files. If anyone has guidance or suggestions on how to implement this, I would appreciate your help.

WebView on macOS
Hello everyone, I am currently working on integrating a WebView into my macOS application, intended to allow users to browse tutorial webpages directly within the app. Although I’ve followed an example that appears syntactically correct, the WebView does not render any webpage content. Below is a code snippet for reference: import SwiftUI import WebKit struct HelpWebView: View { @State private var toggle = false @State private var page = WebPage() private var url: URL { toggle ? URL(string: "https://www.webkit.org")! : URL(string: "https://www.swift.org")! } var body: some View { WebView(page) .onAppear { page.load(URLRequest(url: url)) } .onChange(of: toggle) { page.load(URLRequest(url: url)) } .toolbar { Button("Reload", systemImage: "arrow.clockwise") { toggle.toggle() } } } } I would greatly appreciate any insights or suggestions on what might be causing this issue or how to resolve it. Thank you in advance for your help!

VideoMaterial Black Screen on Vision Pro Device (Works in Simulator)
VideoMaterial Black Screen on Vision Pro Device (Works in Simulator) App Overview App Name: Extn Browser Bundle ID: ai.extn.browser Purpose: A visionOS web browser that plays 360°/180° VR videos in an immersive sphere environment Development Environment & SDK Versions Component Version Xcode 26.2 Swift 6.2 visionOS Deployment Target 26.2 Swift Concurrency MainActor isolation enabled App is released in the TestFlight. Frameworks Used SwiftUI - UI framework RealityKit - 3D rendering, MeshResource, ModelEntity, VideoMaterial AVFoundation - AVPlayer, AVAudioSession WebKit - WKWebView for browser functionality Network - NWListener for local proxy server Sphere Video Mechanism The app creates an immersive 360° video experience using the following approach: // 1. Create sphere mesh (10 meter radius for immersive viewing) let mesh = MeshResource.generateSphere(radius: 10.0) // 2. Create initial transparent material var material = UnlitMaterial() material.color = .init(tint: .clear) // 3. Create entity and invert sphere (negative X scale) let sphere = ModelEntity(mesh: mesh, materials: [material]) sphere.scale = SIMD3<Float>(-1, 1, 1) // Inverts normals for inside-out viewing sphere.position = SIMD3<Float>(0, 1.5, 0) // Eye level // 4. Create AVPlayer with video URL let player = AVPlayer(url: videoURL) // 5. Configure audio session for visionOS let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(.playback, mode: .moviePlayback, options: [.mixWithOthers]) try audioSession.setActive(true) // 6. Create VideoMaterial and apply to sphere let videoMaterial = VideoMaterial(avPlayer: player) if var modelComponent = sphere.components[ModelComponent.self] { modelComponent.materials = [videoMaterial] sphere.components.set(modelComponent) } // 7. Start playback player.play() ImmersiveSpace Configuration // browserApp.swift ImmersiveSpace(id: appModel.immersiveSpaceID) { ImmersiveView() .environment(appModel) } .immersionStyle(selection: .constant(.mixed), in: .mixed) Entitlements <!-- browser.entitlements --> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.network.client</key> <true/> <key>com.apple.security.network.server</key> <true/> Info.plist Network Configuration <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> The Issue Behavior in Simulator: Video plays correctly on the inverted sphere surface - 360° video is visible and wraps around the user as expected. Behavior on Physical Vision Pro: The sphere displays a black screen. No video content is visible, though the sphere entity itself is present. Important: Not a DRM/Licensing Issue This issue is NOT related to Digital Rights Management (DRM) or FairPlay. I have tested with: Unlicensed raw MP4 video files (no DRM protection) Self-hosted video content with no copy protection Direct MP4 URLs from CDN without any licensing requirements The same black screen behavior occurs with all unprotected video sources, ruling out DRM as the cause. (Plain H.264 MP4, no DRM) Screen Recording: Working in Simulator The following screen recording demonstrates playing a 360° YouTube video in the immersive sphere on the visionOS Simulator: https://cdn.commenda.kr/screen-001.mov This confirms that the VideoMaterial and sphere rendering work correctly in the simulator, but the same setup shows a black screen on the physical Vision Pro device. Observations AVPlayer status reports .readyToPlay - The video appears to load successfully VideoMaterial is created without errors - No exceptions thrown Sphere entity renders - The geometry is visible (black surface) Audio session is configured - No errors during audio session setup Network requests succeed - The video URL is accessible from the device Same result with local/unprotected content - DRM is not a factor Console Logs (Device) The logging shows: Sphere created and added to scene AVPlayer created with correct URL VideoMaterial created and applied Player status transitions to .readyToPlay player.play() called successfully Rate shows 1.0 (playing) Despite all success indicators, the rendered output is black. Questions for Apple Are there known differences in VideoMaterial behavior between the visionOS Simulator and physical Vision Pro hardware? Does VideoMaterial(avPlayer:) require specific video codec/format requirements that differ on device? (The test video is a standard H.264 MP4) Is there a required Metal capability or GPU feature for VideoMaterial that may not be available in certain contexts on device? Does the immersion style (.mixed) affect VideoMaterial rendering on hardware? Are there additional entitlements required for video texture rendering in RealityKit on physical hardware? Attempted Solutions Configured AVAudioSession with .playback category Added delay before player.play() to ensure material is applied Verified sphere scale inversion (-1, 1, 1) Tested multiple video URLs (including raw, unlicensed MP4 files) Confirmed network connectivity on device Ruled out DRM/FairPlay issues by testing unprotected content Environment Details Device: Apple Vision Pro visionOS Version: 26.2 Xcode Version: 26.2 macOS Version: Darwin 25.2.0

Passkey authentication issues on iPhone when launching login pages via Home Screen shortcuts
Summary: We are facing a serious issue on iPhone where multiple passkey authentication problems occur when accessing passkey-enabled login pages via shortcuts placed on the iPhone Home Screen. These issues may also occur when opening the same pages directly in a standard browser window. However, launching the login pages from a Home Screen shortcut appears to increase the likelihood of encountering these issues. Affected Services (examples, not exhaustive): Amazon GitHub Adobe Observed Issues: Issue 1: A passkey authentication dialog/popup shows two times without any user operation: What happens due to this issue: Login does not complete after the first passkey authentication. A second passkey authentication UI automatically appears. Completing or canceling the second authentication allows the login to proceed. Issue 2: Login remains stuck until the user manually invokes passkey again What happens due to this issue: The login page does not advance after the first authentication. The user must tap the ID/username field again to manually trigger the passkey UI. Completing the second authentication enables login. Issue 3: Automatic second authentication occurs, but login still fails What happens due to this issue: A second automatic authentication UI appears. Login still does not complete. Tapping the ID field no longer opens the passkey UI; instead, the password auto-fill panel appears. Passkey login becomes impossible. Observed reproduction steps (not guaranteed but most consistently observed): On iPhone, navigate to a passkey-enabled login page (e.g., Amazon, GitHub, Adobe) using a browser. Create a shortcut from the browser's share menu and place it on the Home Screen. Launch the login page from the Home Screen shortcut. Tap the ID/username field to invoke the passkey prompt. Complete passkey authentication. → One of the issues described above occurs. Environment: Device: iPhone SE OS: iOS 18.6.2

Folder-level image access permissions for browser-only web apps in iOS Safari
We are developing a mobile-first, browser-only web application that requires users to upload 20–200 images stored inside a single folder (for example, a merchant product directory). On iOS Safari: window.showDirectoryPicker() is not supported. is not supported. File System Access API is not available. Users must manually multi-select images from the Photos picker. This creates significant friction for bulk upload workflows. We are NOT requesting unrestricted file system access. We are asking whether a privacy-preserving, user-granted folder-scoped permission model is being considered for web applications. For example: User explicitly selects a folder. The web app receives scoped access only to that selected folder. Access is session-bound and revocable. No background or global storage access is required. Questions: Is folder-level access for web apps being considered for iOS Safari? Does installing a PWA provide any enhanced file access capability? Are there recommended best practices for handling bulk image uploads in browser-only iOS applications? Is there any roadmap alignment with the File System Access API standard? Our goal is to remain browser-only and maintain strict user privacy while improving usability for high-volume image workflows. Any clarification on intended platform direction would be appreciated.

Can WKWebView automatically adjust its width and height based on the loaded content?
Hi Team, We're trying to load an Image Ad inside WKWebView and we're wondering if we can adjust its width and height based on the loaded content. Currently, we're using evaluateJavaScript("document.body.scrollHeight") query to fetch the height of the content but often times we get incorrect value from it. We looked at the WKWebView documentation but couldn't find anything related to our use case. Could someone from the team guide us through the next step? Thanks

Issue with loadFileURL in WKWebView on iOS 26.4 Beta
Before iOS 26.3, the WKWebView method open func loadFileURL(_ URL: URL, allowingReadAccessTo readAccessURL: URL) -> WKNavigation? worked fine when both parameters were passed the same path (e.g., h5path/index.html), allowing access to and loading of other files like CSS and JS within the h5path directory. However, in iOS 26.4 Beta, this results in an error, and the second parameter must point to a parent directory. Is this a bug?

In the iOS 26.4 beta version of WKWebView, it is impossible to establish an IP type WebSocket connection!
In iOS 26.4 beta, I noticed that when loading pages using WKWebView and using WebSocket to establish IP type addresses, the connection duration was several seconds and sometimes even failed to connect (normally, the connection duration should be in milliseconds). However, when establishing WebSocket connections using domain names, the connections were normal. Additionally, I discovered a special scenario: When directly establishing WebSocket connections using IP type addresses, it remained in the "connect" state. At the same time, based on Wireshark packet capture, it was found that no TCP connection was sent at this time. However, if two connections with the same address were established simultaneously, those two connections could successfully connect. This bug has seriously affected the use of my application service. Is there a chance that this version will solve the problem?

Which iOS release includes the fix for rdar://163597990 / WebKit Bug
Hi, We're experiencing a WKWebView issue where the screen intermittently turns pure magenta (#FF00FF) in our production iOS app. After investigation, we traced this to WebKit's internal WKCompositingView.mm where [UIColor magentaColor] is used as a pending state indicator when coverView.hidden == NO. This matches rdar://163597990 / WebKit Bug 303157 ("Magenta flash when loading page"), which was fixed in commit 303720@main on 2025-12-01 via PR #54499. My question is simple: which iOS/Safari release includes this fix? We're on iOS 26.3 and still seeing the issue. We need to know: Is the fix already in iOS 26.3? (If so, there may be another unfixed code path) If not, which upcoming iOS version will include it? Our environment iOS 26.3, iPhone 15 Pro Max WKWebView with complex web content App codebase contains zero magenta color usage — this is purely from WebKit Related rdar://163597990 Bug 303157 — RESOLVED FIXED Bug 230531 — "Pages render as magenta after being in background" PR #54499 — Merged to main 2025-12-01 Any information about the release timeline would be very helpful. Thanks!

Face ID / Touch ID is requested twice when using Passkey Autofill
When using iCloud Keychain passkeys with WebAuthn (mediation: "conditional") in non-Safari browsers (e.g. Chrome or WKWebView-based browsers), Face ID / Touch ID is requested twice during Passkey Autofill. This issue occurs only when the focused input field shows a numeric keypad–style keyboard, such as: Japanese Kana Chinese Zhuyin With a standard QWERTY keyboard, authentication completes with a single user verification. Notably: Safari completes authentication with one Face ID / Touch ID prompt even with numeric keypad keyboards. Other browsers require two prompts. The issue does not occur with other credential managers (Google Password Manager, 1Password), suggesting this is specific to iCloud Keychain. This issue has been confirmed on the following OS versions: iOS 17.6.1 iOS 18.7.2 iOS 26.2 iOS 26.3 beta Impact This behavior results in a confusing and unintuitive login experience for users relying on Passkey Autofill. Steps to Reproduce: Go to Settings → Keyboards → Keyboards, and set “Japanese – Kana” as the primary keyboard. Enable Face ID / Touch ID, and make sure “Use Face ID / Touch ID For” → “Password Autofill” is enabled. Open Chrome and navigate to https://webauthn.io. Enter a username and tap “Register” to create a passkey using iCloud Keychain. Tap the username field again so that the “Japanese – Kana” keyboard appears and the passkey suggestion created in step 4 is shown. Tap the passkey suggestion. Face ID / Touch ID is requested twice. === This issue has already been reported via Feedback Assistant as FB21726047. I am posting here to confirm whether this behavior is working as intended or represents a bug, and to make other developers aware of the current behavior.

Voice Control evaluation questions: "Stop Recording" command failure & Item numbers on non-interactive web elements
Hello everyone, I am currently evaluating my app's accessibility features to accurately display the "Accessibility" information on the App Store. I have encountered two specific issues regarding Voice Control testing and would appreciate any guidance. Voice Command for "Stop Recording" According to the evaluation criteria, if an app supports audio recording or dictation, users must be able to start and stop recording using only their voice. Behavior: I can successfully trigger the recording using the command "Start Recording". However, I cannot find a command to stop it. Commands like "Stop Recording" or "Stop" are not recognized by the system. Question: Is there a specific standard voice command intended for stopping a recording? Item Number Overlays on Non-Interactive Web Elements (WKWebView) I noticed an inconsistency between native views and web content regarding Voice Control item numbering. Behavior: When testing web content within the app (WKWebView) or in Safari, Voice Control displays item number overlays on non-interactive text elements (such as standard or tags). In native views, static labels do not receive item numbers. Question: Is this expected behavior for web content? Since these elements are not interactive, I am unsure if this should be considered a bug (fail) or an acceptable exception for the accessibility evaluation. Has anyone experienced similar issues or know the correct criteria for these cases? Thank you.

`PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable()` returns false in non-Safari browsers on iOS 26.2+
There appears to be a regression or restriction in iOS 26.2 and 26.2.1 regarding the Web Authentication API in third-party browsers (browsers other than Safari). Specifically, the method PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable() returns false when called from within non-Safari browsers (e.g., Chrome, Firefox, Edge) on iOS, even when the device supports biometrics (FaceID/TouchID) and Passkeys are enabled. This prevents third-party browsers from correctly detecting Platform Authenticator availability, leading websites to hide Passkey login options or default to cross-device authentication flows instead of using the local device's biometric authenticator. Environment: OS: iOS 26.2, iOS 26.2.1 Device: iPhone 17 Browsers Tested: Chrome iOS and Firefox iOS Steps to Reproduce: Launch Safari on an iOS device running iOS 26.2+. Navigate to https://www.passkeys-debugger.io/. Observe that "Platform Auth" is highlighted in Green (true), indicating the device is eligible for passkey authentication. Launch a non-Safari browser (e.g., Chrome or Firefox) on the same device. Navigate to https://www.passkeys-debugger.io/. Expected Results: "Platform Auth" should be Green (true), matching the behavior in Safari, as the device possesses a built-in platform authenticator. Actual Results: "Platform Auth" is highlighted in Red (false). Impact: This discrepancy fragments the Passkey user experience on iOS. Users preferring third-party browsers are unable to utilize the seamless on-device biometric authentication that is available in Safari. It forces developers to implement complex fallbacks or results in users believing their device is incompatible with Passkeys.

Browser window with URL not opening via ASWebAuth
Our app uses ASWebAuthenticationSession for login. This launches an incognito (ephemeral) browser window of the system’s default browser with the authentication URL. Recently, on the latest macOS Tahoe, we observe that: The browser application is launched(we could see in the dock) But the authentication window with the URL does not appear No error is returned to the app (silent failure)

WebView Exit fullscreen issue on iPadOS
This demonstrates an issue with SwiftUI's WebView on iPadOS. To repro, testing on iPad Simulator OS 26.2, macOS 26.2, Xcode 26.2. Download and unzip this project: https://drive.google.com/file/d/1z3MobjDf_RvvOtriXtinXvrJ7rGHwZRs/view?usp=share_link Set up Signing and Run the swiftui-webview App target on simulator (I'm using iPad Pro 13-inch (M5 simulator) Tap/click the fullscreen [ ] button in the bottom left corner of the webpage. Tap/click the 'X' button in the top left, to exit fullscreen. Result: The WebView exits fullscreen, but there is no content loaded, just a white background. It's also now not possible to visit other URLs - the WebView appears to be unresponsive and not repaint. This does not appear to affect macOS 26.2, just iPadOS.

SwiftUI WebView: Is action.target == nil a Reliable Way to Handle New Window Requests?
In WKWebView, there is the WKUIDelegate method: func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {} This delegate method provides a callback when a new window (for example, target="_blank") is requested in the web view. However, in native SwiftUI (iOS 26), WebView / WebPage APIs do not provide an equivalent delegate method to handle new window requests. As a workaround, I am using the following method: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy {} In this method, when action.target == nil, I treat it as a new window request. My question: Is relying on action.target == nil in decidePolicy a reliable and future-safe way to detect new window requests in SwiftUI’s WebView, or is there a better or more recommended approach for handling target="_blank" / new window navigation in the SwiftUI WebView APIs? Code: public func decidePolicy(for action: WebPage.NavigationAction, preferences: inout WebPage.NavigationPreferences) async -> WKNavigationActionPolicy { guard let webPage = webPage else { return .cancel } // Handle case where target frame is nil (e.g., target="_blank" or window.open) // This indicates a new window request if action.target == nil { print("Target frame is nil - new window requested") // WORKAROUND: Until iOS 26 WebPage UI protocol is available, we handle new windows here // Try to create a new WebPage through UI plugins if handleCreateWebPage(for: webPage, navigationAction: action) != nil { // Note: The new WebPage has been created and published to the view return .allow } } return .allow }

WKWebView + Bluetooth Keyboard: Ctrl+Home / Ctrl+End causes app crash after input blur (iPadOS 18.4.1 / 18.6.2)
1. Summary In a hybrid iOS app using WKWebView (Angular + Capacitor), after programmatically blurring an element and connecting a Bluetooth keyboard, pressing Ctrl+Home or Ctrl+End causes the app to crash. The crash stack shows the issue occurs inside UIKit keyboard handling (UITextInteractionSelectableInputDelegate _moveToStartOfLine), indicating a system-level bug. 2. Steps to Reproduce Open the hybrid app containing a WKWebView. Blur the input (programmatically). Connect a Bluetooth keyboard. Press Ctrl + Home or Ctrl + End. Expected result: No crash. The command should be ignored if no text input is active. Actual result: App crashes immediately. 3.

Build version upload failed
90809: Deprecated API Usage. New apps that use UIWebView are no longer accepted. Instead, use WKWebView for improved security and reliability. Learn more (https://developer.apple.com/documentation/uikit/uiwebview). I did not actively use UIWebView in my app, but this error occurred during the build upload process. This version has an additional integration of the iOS Ayla SDK and Public-9.0.7 SDK compared to the previous version. If there is indeed a call in a third-party SDK, how can I determine where the call exists? Thank you

File Download Support in SwiftUI Native WebView (iOS 26+)
I am using the native SwiftUI WebView and WebPage APIs (iOS 26+) and would like to implement file download functionality using the native SwiftUI WebView. However, I have not been able to find any APIs equivalent to WKDownload. In WKWebView, the WKDownload API can be used to handle downloads. I am looking for a similar API or recommended approach in the native SwiftUI WebView that would allow downloading files. If anyone has guidance or suggestions on how to implement this, I would appreciate your help.

WebView on macOS
Hello everyone, I am currently working on integrating a WebView into my macOS application, intended to allow users to browse tutorial webpages directly within the app. Although I’ve followed an example that appears syntactically correct, the WebView does not render any webpage content. Below is a code snippet for reference: import SwiftUI import WebKit struct HelpWebView: View { @State private var toggle = false @State private var page = WebPage() private var url: URL { toggle ? URL(string: "https://www.webkit.org")! : URL(string: "https://www.swift.org")! } var body: some View { WebView(page) .onAppear { page.load(URLRequest(url: url)) } .onChange(of: toggle) { page.load(URLRequest(url: url)) } .toolbar { Button("Reload", systemImage: "arrow.clockwise") { toggle.toggle() } } } } I would greatly appreciate any insights or suggestions on what might be causing this issue or how to resolve it. Thank you in advance for your help!

VideoMaterial Black Screen on Vision Pro Device (Works in Simulator)
VideoMaterial Black Screen on Vision Pro Device (Works in Simulator) App Overview App Name: Extn Browser Bundle ID: ai.extn.browser Purpose: A visionOS web browser that plays 360°/180° VR videos in an immersive sphere environment Development Environment & SDK Versions Component Version Xcode 26.2 Swift 6.2 visionOS Deployment Target 26.2 Swift Concurrency MainActor isolation enabled App is released in the TestFlight. Frameworks Used SwiftUI - UI framework RealityKit - 3D rendering, MeshResource, ModelEntity, VideoMaterial AVFoundation - AVPlayer, AVAudioSession WebKit - WKWebView for browser functionality Network - NWListener for local proxy server Sphere Video Mechanism The app creates an immersive 360° video experience using the following approach: // 1. Create sphere mesh (10 meter radius for immersive viewing) let mesh = MeshResource.generateSphere(radius: 10.0) // 2. Create initial transparent material var material = UnlitMaterial() material.color = .init(tint: .clear) // 3. Create entity and invert sphere (negative X scale) let sphere = ModelEntity(mesh: mesh, materials: [material]) sphere.scale = SIMD3<Float>(-1, 1, 1) // Inverts normals for inside-out viewing sphere.position = SIMD3<Float>(0, 1.5, 0) // Eye level // 4. Create AVPlayer with video URL let player = AVPlayer(url: videoURL) // 5. Configure audio session for visionOS let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(.playback, mode: .moviePlayback, options: [.mixWithOthers]) try audioSession.setActive(true) // 6. Create VideoMaterial and apply to sphere let videoMaterial = VideoMaterial(avPlayer: player) if var modelComponent = sphere.components[ModelComponent.self] { modelComponent.materials = [videoMaterial] sphere.components.set(modelComponent) } // 7. Start playback player.play() ImmersiveSpace Configuration // browserApp.swift ImmersiveSpace(id: appModel.immersiveSpaceID) { ImmersiveView() .environment(appModel) } .immersionStyle(selection: .constant(.mixed), in: .mixed) Entitlements <!-- browser.entitlements --> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.network.client</key> <true/> <key>com.apple.security.network.server</key> <true/> Info.plist Network Configuration <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> The Issue Behavior in Simulator: Video plays correctly on the inverted sphere surface - 360° video is visible and wraps around the user as expected. Behavior on Physical Vision Pro: The sphere displays a black screen. No video content is visible, though the sphere entity itself is present. Important: Not a DRM/Licensing Issue This issue is NOT related to Digital Rights Management (DRM) or FairPlay. I have tested with: Unlicensed raw MP4 video files (no DRM protection) Self-hosted video content with no copy protection Direct MP4 URLs from CDN without any licensing requirements The same black screen behavior occurs with all unprotected video sources, ruling out DRM as the cause. (Plain H.264 MP4, no DRM) Screen Recording: Working in Simulator The following screen recording demonstrates playing a 360° YouTube video in the immersive sphere on the visionOS Simulator: https://cdn.commenda.kr/screen-001.mov This confirms that the VideoMaterial and sphere rendering work correctly in the simulator, but the same setup shows a black screen on the physical Vision Pro device. Observations AVPlayer status reports .readyToPlay - The video appears to load successfully VideoMaterial is created without errors - No exceptions thrown Sphere entity renders - The geometry is visible (black surface) Audio session is configured - No errors during audio session setup Network requests succeed - The video URL is accessible from the device Same result with local/unprotected content - DRM is not a factor Console Logs (Device) The logging shows: Sphere created and added to scene AVPlayer created with correct URL VideoMaterial created and applied Player status transitions to .readyToPlay player.play() called successfully Rate shows 1.0 (playing) Despite all success indicators, the rendered output is black. Questions for Apple Are there known differences in VideoMaterial behavior between the visionOS Simulator and physical Vision Pro hardware? Does VideoMaterial(avPlayer:) require specific video codec/format requirements that differ on device? (The test video is a standard H.264 MP4) Is there a required Metal capability or GPU feature for VideoMaterial that may not be available in certain contexts on device? Does the immersion style (.mixed) affect VideoMaterial rendering on hardware? Are there additional entitlements required for video texture rendering in RealityKit on physical hardware? Attempted Solutions Configured AVAudioSession with .playback category Added delay before player.play() to ensure material is applied Verified sphere scale inversion (-1, 1, 1) Tested multiple video URLs (including raw, unlicensed MP4 files) Confirmed network connectivity on device Ruled out DRM/FairPlay issues by testing unprotected content Environment Details Device: Apple Vision Pro visionOS Version: 26.2 Xcode Version: 26.2 macOS Version: Darwin 25.2.0

Passkey authentication issues on iPhone when launching login pages via Home Screen shortcuts
Summary: We are facing a serious issue on iPhone where multiple passkey authentication problems occur when accessing passkey-enabled login pages via shortcuts placed on the iPhone Home Screen. These issues may also occur when opening the same pages directly in a standard browser window. However, launching the login pages from a Home Screen shortcut appears to increase the likelihood of encountering these issues. Affected Services (examples, not exhaustive): Amazon GitHub Adobe Observed Issues: Issue 1: A passkey authentication dialog/popup shows two times without any user operation: What happens due to this issue: Login does not complete after the first passkey authentication. A second passkey authentication UI automatically appears. Completing or canceling the second authentication allows the login to proceed. Issue 2: Login remains stuck until the user manually invokes passkey again What happens due to this issue: The login page does not advance after the first authentication. The user must tap the ID/username field again to manually trigger the passkey UI. Completing the second authentication enables login. Issue 3: Automatic second authentication occurs, but login still fails What happens due to this issue: A second automatic authentication UI appears. Login still does not complete. Tapping the ID field no longer opens the passkey UI; instead, the password auto-fill panel appears. Passkey login becomes impossible. Observed reproduction steps (not guaranteed but most consistently observed): On iPhone, navigate to a passkey-enabled login page (e.g., Amazon, GitHub, Adobe) using a browser. Create a shortcut from the browser's share menu and place it on the Home Screen. Launch the login page from the Home Screen shortcut. Tap the ID/username field to invoke the passkey prompt. Complete passkey authentication. → One of the issues described above occurs. Environment: Device: iPhone SE OS: iOS 18.6.2

Folder-level image access permissions for browser-only web apps in iOS Safari
We are developing a mobile-first, browser-only web application that requires users to upload 20–200 images stored inside a single folder (for example, a merchant product directory). On iOS Safari: window.showDirectoryPicker() is not supported. is not supported. File System Access API is not available. Users must manually multi-select images from the Photos picker. This creates significant friction for bulk upload workflows. We are NOT requesting unrestricted file system access. We are asking whether a privacy-preserving, user-granted folder-scoped permission model is being considered for web applications. For example: User explicitly selects a folder. The web app receives scoped access only to that selected folder. Access is session-bound and revocable. No background or global storage access is required. Questions: Is folder-level access for web apps being considered for iOS Safari? Does installing a PWA provide any enhanced file access capability? Are there recommended best practices for handling bulk image uploads in browser-only iOS applications? Is there any roadmap alignment with the File System Access API standard? Our goal is to remain browser-only and maintain strict user privacy while improving usability for high-volume image workflows. Any clarification on intended platform direction would be appreciated.

Can WKWebView automatically adjust its width and height based on the loaded content?
Hi Team, We're trying to load an Image Ad inside WKWebView and we're wondering if we can adjust its width and height based on the loaded content. Currently, we're using evaluateJavaScript("document.body.scrollHeight") query to fetch the height of the content but often times we get incorrect value from it. We looked at the WKWebView documentation but couldn't find anything related to our use case. Could someone from the team guide us through the next step? Thanks

Issue with loadFileURL in WKWebView on iOS 26.4 Beta
Before iOS 26.3, the WKWebView method open func loadFileURL(_ URL: URL, allowingReadAccessTo readAccessURL: URL) -> WKNavigation? worked fine when both parameters were passed the same path (e.g., h5path/index.html), allowing access to and loading of other files like CSS and JS within the h5path directory. However, in iOS 26.4 Beta, this results in an error, and the second parameter must point to a parent directory. Is this a bug?

In the iOS 26.4 beta version of WKWebView, it is impossible to establish an IP type WebSocket connection!
In iOS 26.4 beta, I noticed that when loading pages using WKWebView and using WebSocket to establish IP type addresses, the connection duration was several seconds and sometimes even failed to connect (normally, the connection duration should be in milliseconds). However, when establishing WebSocket connections using domain names, the connections were normal. Additionally, I discovered a special scenario: When directly establishing WebSocket connections using IP type addresses, it remained in the "connect" state. At the same time, based on Wireshark packet capture, it was found that no TCP connection was sent at this time. However, if two connections with the same address were established simultaneously, those two connections could successfully connect. This bug has seriously affected the use of my application service. Is there a chance that this version will solve the problem?

Which iOS release includes the fix for rdar://163597990 / WebKit Bug
Hi, We're experiencing a WKWebView issue where the screen intermittently turns pure magenta (#FF00FF) in our production iOS app. After investigation, we traced this to WebKit's internal WKCompositingView.mm where [UIColor magentaColor] is used as a pending state indicator when coverView.hidden == NO. This matches rdar://163597990 / WebKit Bug 303157 ("Magenta flash when loading page"), which was fixed in commit 303720@main on 2025-12-01 via PR #54499. My question is simple: which iOS/Safari release includes this fix? We're on iOS 26.3 and still seeing the issue. We need to know: Is the fix already in iOS 26.3? (If so, there may be another unfixed code path) If not, which upcoming iOS version will include it? Our environment iOS 26.3, iPhone 15 Pro Max WKWebView with complex web content App codebase contains zero magenta color usage — this is purely from WebKit Related rdar://163597990 Bug 303157 — RESOLVED FIXED Bug 230531 — "Pages render as magenta after being in background" PR #54499 — Merged to main 2025-12-01 Any information about the release timeline would be very helpful. Thanks!
