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.

Focus issues with ScrollView iOS18
When using an app via external keyboard, FocusState and .focused used to work just fine until iOS17. Vertical-axis textfields were also accessible without any issues. But after iOS18 update, adding focused modifier removes elements out of focus order of external keyboard. 1 such example is -when a button using focused modifier and @FocusSate is inside a ScrollView and if this view is getting opened via NavigationLink, that button is not accessible via Bluetooth (external) keyboard. TextEditor / Vertical-axis TextFields also seem to be impacted in external-keyboard-focus-order when added inside ScrollView. Is this a known iOS18 issue with ScrollView / any tip to get this fixed ? Sample code that can reproduce this issue: struct ContentView: View { @State private var showBottomSheet: Bool = false @State private var goToNextView: Bool = false @FocusState private var focused: Bool @AccessibilityFocusState private var voFocused: Bool var body: some View { NavigationView { VStack { Text("Hello, world!") // This button works fine in Bluetooth keyboard in all versions Button("Trigger a bottomsheet") { showBottomSheet = true } .focused($focused) .accessibilityFocused($voFocused) Button("Goto another view") { goToNextView = true } NavigationLink( destination: View2(), isActive: $goToNextView ) { EmptyView() } .accessibility(hidden: true) } .sheet(isPresented: $showBottomSheet, onDismiss: { focused = true voFocused = true }, content: { VStack() { Text("Hello World ! I'm in a bottomsheet") Button("Close me") { showBottomSheet = false } } }) .padding() } } } #Preview { ContentView() } struct View2: View { @FocusState private var focused: Bool @AccessibilityFocusState private var voFocused: Bool @State private var showBottomSheet: Bool = false var body: some View { ScrollView { VStack { Text("check") // In iOS18, this button doesn't get focused in Bluetooth / external keyboard // This issue occurs when these 3 combine in iOS 18 - a button using FocusState inside a view that has a ScrollView & it is opened via NavigationLink Button("Trigger a bottomsheet") { showBottomSheet = true } .focused($focused) .accessibilityFocused($voFocused) Button("Test button") { } } .sheet(isPresented: $showBottomSheet, onDismiss: { focused = true voFocused = true }, content: { VStack() { Text("Hello World ! I'm in a bottomsheet") Button("Close me") { showBottomSheet = false } } }) .padding() } } }

Custom Keyboard Extension Not Showing in Settings for Activation
Hi everyone, I’m developing a React Native iOS app that includes a custom keyboard extension for sending stickers across apps. The project builds successfully, and the main app installs fine on my test device. However, I’m not seeing the keyboard extension appear under Settings → General → Keyboard → Keyboards → Add New Keyboard, which means I can’t activate it or grant access. At this point, I’m not even sure if the extension is actually being installed on the device along with the main app. Here’s what I’ve done so far. I created a Keyboard Extension target in Xcode, set the correct bundle identifiers and provisioning profiles, and enabled “Requests Open Access” in the extension’s Info.plist. I built and installed the app on a physical device rather than the simulator to ensure proper testing. My main questions are: how can I confirm that the extension is being installed on the device, and if it isn’t, what might prevent it from installing even though the build completes successfully? Any insights, troubleshooting steps, or guidance would be greatly appreciated.

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。

Accessibility Traits for Children of a Tab Bar
Hi! I'm working on an application where I'd like VoiceOver to give each element of a tab bar the "Tab" trait. I'm testing this using the Accessibility Inspector. Essentially, I'd like to replicate the behavior of how Safari identifies each of its tabs as a "Tab" (I've attached a photo below). How exactly is this accomplished? I've tried using the .isTabBar trait to designate the child objects as "Tabs", but this doesn't seem to be working and I've struggled to find documentation about this. For additional context, these child items are Buttons, and I would like to have the .isButton trait essentially replaced by something like an .isTab trait. Not sure if this is actually possible or not, but curious how the Accessibility Inspector recognizes this in Safari.

CFPrefsPlistSource Read Error with App Group Preferences
I am encountering the following issue while working with app group preferences in my Safari web extension: Couldn't read values in CFPrefsPlistSource<0x3034e7f80> (Domain: [MyAppGroup], User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd. I am trying to read/write shared preferences using UserDefaults with an App Group but keep running into this error. Any guidance on how to resolve this would be greatly appreciated! Has anyone encountered this before? How can I properly configure my app group preferences to avoid this issue?

App in Unlisted Language
I am building a language learning app for a Unlisted Primary Language. Any suggestions or heads ups? My plan is to select english and go with it. Its unfortunate that I have to list a language learning app incorrectly and a tag for that language probably does not exist across the apple system.

Accessibility & Inclusion
We are developing Apple AI for foreign markets and adapting it for iPhone models 17 and above. When the system language and Siri language are not the same—for example, if the system is in English and Siri is in Chinese—it can cause a situation where Apple AI cannot be used. So, may I ask if there are any other reasons that could cause Apple AI to be unavailable within the app, even if it has been enabled?

ApplePay Merchant Session - Could not create SSL/TLS secure channel issue
As part of apple pay implementation we are trying to create a merchant session by trying to connect to apple endpoint https://apple-pay-gateway-cert.apple.com/paymentservices/startSession. While trying to do so we are facing an error “An error occurred while sending the request. The request was aborted: Could not create SSL/TLS secure channel.” . I call the validation url by passing to a C# .Net Framework 4.8 Web API. The API setups an HttpClient with the Merchant Identity Validation Certificate found in my apple account and calls the validation url passing in the required Json Validation Object. When I call PostAsync() I get an exception with the above error message Code is working successfully on my local machine but facing this issue while deployed on Dev / Model environment for testing. We have used Azure app service for deployment and TLS version 1.2 already present here. We have used the Merchant Identity certificate that was issued and have also checked with networking and infrastructure team to make its not an issue from our side. Does anyone have any other idea what could be causing this error. Thank you, Supriya

Handling VoiceOver Focus When Screen Changes (Push, Present, and SplitViewController)
I have some doubts about how VoiceOver handles focus when the screen updates. When a new UIViewController is pushed onto a UINavigationController or presented modally, how does VoiceOver decide which element to focus on? Is there a way to control or customize this behavior? In a UISplitViewController, when an item is selected in the primary view controller, the focus should shift to the relevant content in the secondary view controller. How can we ensure that VoiceOver correctly moves focus to the right element in the secondary panel?

Make Accessibility Focus move to UIPickerView when tapping on UITextField (Full Keyboard Access)
I have a UITextField in my application for entering a state. If I tap on it, a UIPickerView pops up and let's the user select a state (but they can still type too). The issue relates to Full Keyboard Access. If we select the UITextField using an external keyboard, the UIPickerView appears, but in order to get to it the user has to tab through the whole view controller to get to the UIPickerView at the end. What would be nice is to a) move focus directly to the UIPickerView (have it highlighted in blue and scrollable right away with keyboard) or b) make the UIPickerView the next view that's accessible when tabbing over or using the arrow keys. I've tried using: UIAccessibility notifications (both .screenChanged and .layoutChanged, with and without a delay). This ended up only announcing the view, but didn't help with full keyboard access. Making the UIPickerView a first responder when it appears. Attempting to change the accessibilityElements order (but with so many views and views within views, this isn't really a viable option either). Pressing tab + -> (tab and right arrow button) will quickly take the user to the end of the chain of accessibility elements, in other words, to the UIPickerView. But there has to be a cleaner way of just automatically setting the focus to the UIPickerView or making it the next element by pressing the arrow key.

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.

iOS: How to maintain good app icon contrast in grayscale mode?
I’m developing an iOS app, and I’ve noticed that when the user enables Accessibility → Display & Text Size → Color Filters → Grayscale, my app icon loses a lot of visual contrast. The original colored version looks fine, but in grayscale it appears “flat” and harder to distinguish, unlike a pure black-and-white design. What I want to achieve: Ensure the app icon remains visually clear and high-contrast even when iOS renders it in grayscale. Ideally, provide an alternate “high-contrast” app icon version when grayscale mode is enabled. What I’ve tried: Increased color contrast in the original icon design. Added outlines and stronger shapes. Tested with grayscale filters in design tools. Researched Asset Catalog and alternate icons, but found no documented API to detect or respond to grayscale mode. Questions: Is there any API in iOS that allows detecting when the system is in grayscale mode so that I can programmatically switch to an alternate app icon? If not, are there Apple-recommended best practices for designing app icons that still look clear in grayscale? Are there any accessibility guidelines specifically addressing icon design for grayscale or color-blind modes? Additional info: iOS version tested: iOS 17.5 Development in Swift + SwiftUI, using Asset Catalog for icons. I am aware that iOS supports alternate icons via setAlternateIconName, but I haven’t found a trigger for grayscale mode.

iPhone screen layers
I need to understand the different layers that are there in the iPhone X and later OLED screens as I am designing a hardware attachment. They seem to be projecting letters and images from a different layer than the subpixel layer. Is this proprietary information, or is there a resource that explores them?
