CallKit連携でError 4099が頻発し、NEAppPushDelegateの通知が取得できず着信画面が表示されない問題について
iOSアプリでNEAppPushSessionを使い、NEAppPushDelegateの通知を受けてCallKitの着信画面を表示する実装をしていますが、以下の問題に直面しています。 8/13 ログにて下記のエラーが頻発しました。 通知の受け取りテストを約120回してその間ずっとこのエラーが出ていました。 エラー 2025-08-14 11:27:06.793073 +0900 nesessionmanager NESMAppPushSession[SimplePushDefaultConfiguration:7B7218F3-94B5-4AE5-9B9E-94E176694D02] failed to report incoming call to CallKit, error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.callkit.networkextension.messagecontrollerhost was invalidated from this process." UserInfo={NSDebugDescription=The connection to service named com.apple.callkit.networkextension.messagecontrollerhost was invalidated from this process.} このエラーログが頻発した後、callkitの通知画面が表示されなくなりました。 ですがどうやら通知の監視は開始しているようです。 15時間後の8/14 時間をあけたからか、再度通知が来るようになりました。 ですが再度通知の受け取りテストを行った時に同じエラーログが出ました。 再度通知テストを約120回程行ったら、このエラーログが頻発した後、callkitの通知画面が表示されなくなりました。 ですがどうやら今回も通知の監視は開始しているようです。 15時間後の8/15 今日は15時間かけても通知を取得できませんでした。 ですが同じく通知の監視は開始していそうです。 iPhoneの再起動、Xcodeのクリーンアップ、アンインストールして再インストールなどしても通知は来ないままでした。 また、不思議なことに通知が来ない事象が起きた端末以外でも同じように通知を取得することができません。 他の通知は受け取ることができますが独自の通知であるNEAppPushManagerだけ通知を取得することができません。 質問です。 再度通知を出すためには何をすれば良いでしょうか。 この事象は4099エラーを出しすぎたことにより発生する障害なのでしょうか。 4099エラーを出ている原因は何でしょうか。

Download Voices screen
System settings => Accessibility => System Voice => the little (i) beside the pulldown => Voices => THIS SCREEN will allow you to download Premium Voices Is there a way to trigger this screen programmatically. Or at least a link to get my users there without having to dig thru that swamp of screens?

Apple greets Global Accessibility Awareness Day with severe accessibility violations on macOS
I'm reposting here my FB17602742, submitted yesterday: The strong wording of this message comes from years of Apple ignoring the needs of users who can't tolerate UI animations and convulsions. At this point, it's clear that Apple is either intentionally harming users like me or simply doesn't care about meeting even the most basic accessibility standards on macOS. Yes, many UI animations and convulsions can, fortunately, be disabled - but not through straightforward UI controls. Instead, users are forced to look for obscure Terminal commands found scattered across the Internet. The "Reduce motion" checkbox in System Settings is simply a fake control that doesn't do anything - instead of actually disabling all UI animations and convulsions. What's worse, two of the most offensive UI animations cannot be disabled at all. Apple has consistently dismissed requests to let users disable the following UI animations: Scroll bar rollover highlight effect (introduced on macOS 10.7.3). Every time the cursor passes over a scroll bar, it gets highlighted. This draws the user's attention to random scroll bars for no reason - just because the cursor happened to pass over them. It results in HUNDREDS of unnecessary, annoying events of distraction daily!
 Expand/collapse animation of NSOutlineView (e.g., when opening/closing folders in the list view in the Finder, or any other app using outline views). This animation is extremely distracting, irritating, and time-wasting. Global Accessibility Awareness Day is approaching. Dear Apple, Please adhere to the most basic accessibility standards. Stop the needless suffering of countless users like me. Let us disable the two aforementioned UI convulsions. Thank you for your attention to the issue.

False 3.1.1 Rejection: Real-World Dues Payments App
Hello everyone, Our community dues payment app only facilitates real-world maintenance-dues payments directly to property managers’ bank accounts. However, during testing it was likely flagged by the AI-driven review system for a metadata criterion and rejected under Guideline 3.1.1 (“Paid digital content must use IAP”). Meanwhile, hundreds of similar apps remain live on the App Store using the exact same model: The app is completely free No digital content or subscriptions are sold Dues payments are made via bank transfer or credit card directly to the manager Has anyone else encountered this? How did you overcome the metadata check in the AI-driven review process? Thanks!

External Keyboard DatePicker Issues
I am currently trying to get my app ready for full external keyboard support, while testing I found an issue with the native DatePicker. Whenever I enter the DatePicker with an external keyboard it only jumps to the time picker and I am not able to move away from it. Arrow keys don't work, tab and control + tab only move me to the toolbar and back. This is how they look like private var datePicker: some View { DatePicker( "", selection: date, in: minDate..., displayedComponents: [.date] ) .fixedSize() .accessibilityIdentifier("\(datePickerLabel).DatePicker") } private var timePicker: some View { DatePicker( "", selection: date, in: minDate..., displayedComponents: [.hourAndMinute] ) .fixedSize() .accessibilityIdentifier("\(datePickerLabel).TimePicker") } private var datePickerLabelView: some View { Text(datePickerLabel.localizedString) .accessibilityIdentifier(datePickerLabel) } And we implement it like this in the view: HStack { datePickerLabelView Spacer() datePicker timePicker } Does anyone know how to fix this behavior? Is it our fault or is it the system? The issue comes up both in iOS 18 and 26.

Using WebSocket for BCI Click Input in VisionOS - FocusState vs. System-Level Limitations
Hi everyone, My team and I are developing an accessibility-focused VisionOS app (MindTap) as part of a university project, aiming to support individuals with Locked-In Syndrome using Brain-Computer Interface (BCI) signals to trigger interactions (e.g., tapping) within the Apple Vision Pro environment. Problem 1: Simulating Eye Tracking in Simulator We are testing onHover with Send pointer to the device under I/O > Input in the simulator, and while it mostly works (a bit laggy), we found that onHover won't function on the actual Vision Pro hardware. From what I understand, we should be using FocusState for proper gaze interaction, but testing this requires the physical device. Is there any workaround or official Apple-recommended way to simulate Focus-based gaze detection without a real Vision Pro? Problem 2: WebSocket-triggered "Click" doesn't work outside the app We successfully use WebSocket to send a custom signal (a "1" from the brain signal device) to trigger an action inside our app. However, when the user opens a third-party app like Apple News, the WebSocket-triggered "click" no longer works. We suspect this is due to sandbox restrictions or lack of system-level permissions. Is it possible in anyway to: Trigger interaction events outside the app using custom input (like BCI via Websocket)? Access system-wide click/tap simulation APIs from within VisionOS apps Integrate this with accessibility services (like Voice Control or AssistiveTouch) We'd appreciate any official guidance or tips from others building similar accessibility apps with alternative input methods in VisionOS. Thanks in advance for any insight you can provide!

Thai input glitch after Command + Delete in macOS beta
Issue: When using the shortcut Command + Delete to clear a line of text, the next character I type in Thai unexpectedly appears as an English character, even though the input source is still set to Thai. After that, subsequent characters return to Thai as expected. Details: Affected apps: Notes, Messages, and some other native apps Not affected: Browser text fields (Safari, Chrome, etc.) Does not occur when using Option + Delete or just Delete macOS [insert beta version + build number] Mac model: [insert model] Input sources: Thai – Kedmanee, English – U.S. Steps to reproduce: Open Notes (or Messages). Switch to Thai input. Type a few Thai words. Press Command + Delete. Type again — the first character shows up in English. Expected: First character should remain in Thai, consistent with the active input source. Actual: First character shows as English, then input switches back to Thai.

Apple Developer Program Purchase Not Saving Progress
I’m trying to enroll in the Apple Developer Program as an individual. I’ve gone through the steps on the website and started the purchase process. However, after a couple of days when I return to the site, it doesn’t remember my progress — I have to start the enrollment from scratch every time. Is this expected behavior? Am I missing a step to save my progress or complete the enrollment properly? Any help or guidance would be appreciated. Thank you!

TabItems in swiftUI do not scale
I have a TabView with a sample tabItem as follows: .tabItem { Label ("Import", systemImage:"doc.on.doc") .accessibilityLabel("Import Text") } But accessibility settings for large display size on does not seem to work, nor do dynamic font sizes: .tabItem { Label ("Import", systemImage:"doc.on.doc") .font(.largeTitle) .accessibilityLabel("Import Text") } The tabItems appear as a fixed size. The tab contents scale well, so this does not look pleasant at all. Is this a known bug in SwiftUI?

VoiceOver Headings Accessibility Rotor with SwiftUI on iOS
Hi, On iOS, I'd like to mark views that are inside a LazyVStack as headers for VoiceOver (make them appear in the headings rotor). In a VStack, you just have add .accessibilityAddTraits(.isHeader) to your header view. However, if your view is in a LazyVStack, that won't work if the view is not visible. As its name implies, LazyVStack is lazy so that makes sense. There is very little information online about system rotors, but it seems you are supposed to use .accessibilityRotor() with the headings system rotor (.accessibilityRotor(.headings)) outside of the LazyVStack. Something like the following. .accessibilityRotor(.headings) { ForEach(entries) { entry in // entry.id must be the same as the id of the SwiftUI view it is about AccessibilityRotorEntry(entry.name, id: entry.id) } } It kinds of work, but only kind of. When using .accessibilityAddTraits(.isHeader) in a VStack, the view is in the headings rotor as soon as you change screen. However, when using .accessibilityRotor(.headings), the headers (headings?) are not in the headings rotor at the time the screen appears. You have to move the accessibility focus inside the screen before your headers show up. I'm a beginner in regards to VoiceOver, so I don't know how a blind user used to VoiceOver would perceive this, but it feels to me that having to move the focus before the headers are in the headings rotor would mean some users would miss them. So my question is: is there a way to have headers inside a LazyVStack (and are not necessarily visible at first) to be in the headings rotor as soon as the screen appears? (be it using .accessibilityRotor(.headings) or anything else) The "SwiftUI Accessibility: Beyond the basics" talk from WWDC 2021 mentions custom rotors, not system rotors, but that should be close enough. It mentions that for accessibilityRotor to work properly it has to be applied on an accessibility container, so just in case I tried to move my .accessibilityRotor(.headings) to multiple places, with and without the accessibilityElement(children: .contain) modifier, but that did not seem to change the behavior (and I could not understand why accessibilityRotor could not automatically make the view it is applied on an accessibility container if needed). Also, a related question: when using .accessibilityRotor(.headings) on a screen, is it fine to mix uses of .accessibilityRotor(.headings) and .accessibilityRotor(.headings)? In a screen with multiple type of contents (something like ScrollView { VStack { MyHeader(); LazyVStack { /* some content */ }; LazyVStack { /* something else */ } } }), having to declare all headers in one place would make code reusability harder. Thanks

Defining boundaries of inline dialogs for VO users
Hello, I had submitted a question to clarify which components have accessibility APIs that trigger haptics for VoiceOver users https://developer.apple.com/forums/thread/773182. The question stems from perhaps a more direct question about specific components: do tablists and disclosures natively intend to include haptics or screen reader hint or other state or properties to indicate to screen reader users where the component begins or ends? In some web experiences there are screen reader hint text stating "end of..." or "entering" as a way to define the boundaries of these inline dialogs. I had asked about haptics in the prior thread because I do not recall natively implemented version of this except in some haptic cues but have not experienced them consistently so I am not sure if that is an intended native Swift implementation or perhaps something custom.

Camera Crashes
Hi everybody, I'm trying to build a QR-Code Scanner and Generator App for IOS. Whenever I try to implement the camera the app crashes with this comment: This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data. I tried to reduce the app to the minimum of nothing but camera with the same result. Any ideas? Tank you and best Regards Horst Schippers

A Summary of the WWDC25 Group Lab - Accessibility
A Summary of the WWDC25 Group Lab - Accessibility At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for Accessibility. Accessibility Nutrition Labels are a really big step forward for the experience people have on the App Store to find apps that will work for them. How should developers get started with Accessibility Nutrition Labels? A good starting point is to review the Accessibility Nutrition Label evaluation criteria on App Store Connect Help. It's a concise document, roughly 10 pages, and you can approach it section by section after the introduction. Even with prior experience using accessibility features like VoiceOver, the criteria offer valuable insights that might not be immediately apparent. For those newer to accessibility, a good entry point might be one of the visual feature labels, such as Dark Interface, which is a popular and frequently used feature. Which accessibility features can I indicate support for in Accessibility Nutrition Labels? The accessibility features covered include support for assistive technologies like VoiceOver and Voice Control, media enhancements such as captions and audio descriptions, and display accommodations. These display accommodations cover options like larger text, dark interface, differentiating without color alone, sufficient contrast, and reduced motion. With the new Accessibility Nutrition Labels, will app store reviewers validate what we select? The Accessibility Nutrition Label can be edited at any time without requiring a new app submission. However, if an app inaccurately claims feature support, App Review may contact the developer and request an update to the label or the app. Are there any updates to tools for analyzing the accessibility of our apps? Although there aren't new updates this year, continued support for Accessibility Audits is available through Xcode's built-in Accessibility Inspector. XCTest also supports accessibility audits, enabling developers to test app accessibility with every build. These audits analyze aspects like contrast, dynamic type, text clipping, element labels, and more within each view. For a deeper dive, the "Perform accessibility audits for your app" session from WWDC 2023 is a valuable resource. What are accessibility features you wish more people integrated? Accessibility features encompassing user input labels optimized for voice control, keyboard navigation and shortcuts, and dynamic type support could be more used to benefit users. What were some of the biggest accessibility challenges your team encountered while developing Liquid Glass? Apple is known for its innovation and strives to deliver a high-quality experience for everyone. Accessibility is considered a core component of visual design from the outset. For example, the Liquid Glass design inherently supports reduced transparency and increased contrast. As design continues to evolve, user feedback submitted through Feedback Assistant is invaluable. How does Liquid Glass respond to contrast? Especially for text and low contrast environments. Content legibility is a crucial aspect of the Liquid Glass design. It inherently supports accessibility features like reduced transparency and increased contrast. Your feedback during the beta period and beyond is essential to ensuring Liquid Glass provides a great experience within your apps. What are some Apple apps that stand out for their accessibility? Apps like Keynote in the iWork suite offer groundbreaking VoiceOver features to enhance creative productivity for all users. Assistive Access makes core apps such as Messages, Photos, Camera, Phone, and Music more accessible. Podcasts provides transcripts to broaden its reach, and frameworks like SwiftUI ensure that apps built with the latest UI frameworks have excellent built-in accessibility.

VoiceOver is not respecting lang in HTML option
I have an HTML select that has Spanish text in the options. When VoiceOver reads the selected option (unopened), it switches to Spanish as expected. However, when you open the select box and browse through the options, it uses the English voice to read the Spanish text. I have tried adding lang on to the select tag and the option tag but neither helps https://codepen.io/grahamfowles/pen/VYYRxMK

Programmatically Modifying Per Application or System Wide Color Filters using Cocoa/Swift in MacOS?
I'm looking into how to programmatically control color filters in the Accessibility settings under "System Settings" -> "Accessibility" -> "Color Filters"--in particular the "Intensity" and "Filter type" settings. As far as I have gathered, changing this setting can only be accomplished using the CoreGraphics APIs or Accessibility APIs (I've poked around GitHub, Stack Overflow, and queried some LLMs), but there doesn't seem to be a clear cut example for doing this using public facing APIs, without ripping off source code from another project wholesale or using private APIs. My goal is to overlay a color filter at either a per-application or system level to help with accessibility. If there's a way to overlay this capability on an application-by-application basis as a third-party developer, that would be the most ideal scenario. For example, modifying the look and feel/UX for Launchpad, Photos, etc, as a third-party developer without accessing the source code of the application that I'm modifying the look/feel for (with appropriate user consent of course).

Attaching procedural audio to an ARKit SCNNode
I’m developing an ARKit application where I aim to attach procedurally generated audio to detected planes in the environment. While using a static audio file with SCNAudioSource and SCNAudioPlayer works as expected, integrating procedural audio via AVAudioSourceNode does not produce any sound, nor does it generate any error messages: Stack Overflow Post Working Implementation with Static Audio File: let audioPlayer = SCNAudioPlayer(source: audioSource) node.addAudioPlayer(audioPlayer) Attempted Implementation with Procedural Audio: // Audio generation code } let audioPlayer = SCNAudioPlayer(avAudioNode: audioNode) node.addAudioPlayer(audioPlayer) In this setup, the AVAudioSourceNode successfully generates audio when connected directly to an AVAudioEngine. However, when used with SCNAudioPlayer and attached to an SCNNode, it fails to produce sound. What doesn’t work is creating some procedural audio with an AVAudioNode, as documented here: Apple docs Additionally, I explored the WWDC18 AR game project, SwiftShot, which utilizes SCNAudioPlayer(avAudioNode:). After updating it for the latest Xcode, the graphics function correctly, but the audio does not play. I also noted that the Apple documentation mentions an audioPlayerWithAVAudioNode: method, stating: Using this initializer is typically not necessary. Instead, call the audioPlayerWithAVAudioNode: method, which returns a cached audio player object if one for the specified AVAudioNode object has already been created and is available for use. However, this method does not appear to be available in Swift. Any insights or guidance on this matter would be greatly appreciated.

Avoid trackpad gesture conflict between dragging and accessibility zooming when using three fingers
Double-tap three fingers and drag to change zoom” should suppress “Three Finger to Drag”. Currently these gestures are triggered simultaneously, for no real reasons. I saw different behaviors for different environments, but none is desired. Current and desired behavior: This seems an issue so I filed a feedback.
