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.

I need to direct text-to-speech generated audio from my app simultaneously to a bluetooth speaker device AND to the internal iPad speaker. The app uses AVSpeechSynthesizer and several third party speech engines. How best to do this? I noticed the outputChannels property on AVSpeechSynthesizer...are there any examples of how to use this?

I have a product for designing particle emitters, which I suspect may be of limited interest to people with limited vision. I'd still like to ensure I'm doing a good job with VoiceOver mode. There's a related, simplified sample online, if you want to look at the code As you can see from the picture below, a large part of the interface mimics Xcode's particle editor, with many value entry controls that combine up/down buttons with a tappable label. Tapping the label goes into edit mode. Apart from changing how labels are stepped through in voiceover in my app, how should I handle these stepper buttons? Is this a good place to use a Custom Rotor?

I have implemented a SwiftUI view containing a grid of TextField elements, where focus moves automatically to the next field upon input. This behavior works well on iOS 16 and 17, maintaining proper focus highlighting when keyboard full access is enabled. However, in iOS 18 and above, the keyboard full access focus behaves differently. It always stays behind the actual focus state, causing a mismatch between the visually highlighted field and the active text input. This leads to usability issues, especially for users navigating with an external keyboard. Below is the SwiftUI code for reference: struct AutoFocusGridTextFieldsView: View { private let fieldCount: Int private let columns: Int @State private var textFields: [String] @FocusState private var focusedField: Int? init(fieldCount: Int = 17, columns: Int = 5) { self.fieldCount = fieldCount self.columns = columns _textFields = State(initialValue: Array(repeating: "", count: fieldCount)) } var body: some View { let rows = (fieldCount / columns) + (fieldCount % columns == 0 ? 0 : 1) VStack(spacing: 10) { ForEach(0..<rows, id: \.self) { row in HStack(spacing: 10) { ForEach(0..<columns, id: \.self) { col in let index = row * columns + col if index < fieldCount { TextField("", text: $textFields[index]) .frame(width: 40, height: 40) .multilineTextAlignment(.center) .textFieldStyle(RoundedBorderTextFieldStyle()) .focused($focusedField, equals: index) .onChange(of: textFields[index]) { newValue in if newValue.count > 1 { textFields[index] = String(newValue.prefix(1)) } if !textFields[index].isEmpty { moveToNextField(from: index) } } } } } } } .padding() .onAppear { focusedField = 0 } } private func moveToNextField(from index: Int) { if index + 1 < fieldCount { focusedField = index + 1 } } } struct AutoFocusGridTextFieldsView_Previews: PreviewProvider { static var previews: some View { AutoFocusGridTextFieldsView(fieldCount: 10, columns: 5) } } Has anyone else encountered this issue with FocusState in iOS 18? I really do believe that this is a bug strictly connected to keyboard navigation since I experienced similar problem also on UIKit equivalent of the view. Any insights or suggestions would be greatly appreciated!

When I am doing a file search, in TextEdit, and on certain webistes the space bar will quit functioning as soon as i start typing. If I hold down the "Option" key it allows the space bar to work as normal. I have checked every setting I can think of and nothing has helped.

At present, in iOS, if using the in-house app, there may be crashes in the new iOS 18.3 and later versions, but it works normally on other phones and the certificate is not problematic. A total of 3 machines were found, and there was no pattern between the machines and the system, with different models and versions. We tested it on a machine that crashes, but the app downloaded from the store doesn't. If the same app is packaged and installed directly in the development tool, it will crash. Is this related to compatibility with the new version of IOS? Is there a solution? Do others also have relevant situations?

Hello, When I listen to title in my app with VoiceOver, it makes a strange sound. This characters make with Korean+number+Alphabet. Is this combination makes some strange sound with voice over? I would like to ask if Apple can fix this issue. Thank you.

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?

Context: We are using UIKit to provide accessibility in our app for our iOS users. Our app majorly contains documents/books that user can read. Issue: The issue is VoiceOver is skipping the lines given to it when there are some leading spaces in it. We have observed this issue in different languages. This is only happening for line granularity, other granularities seems to be working as expected. Implementation: We are using below API's to provide line content to voice over. UIAccessibilityReadingContent - accessibilityPageContent - accessibilityFrameForLineNumber - accessibilityContentForLineNumber We are creating UIAccessibilityElement objects to pass to VoiceOver and each UIAccessibilityElement implements UIAccessibilityReadingContent to provide readable content. We also use below APIs to cross element boundaries for all granular navigations. accessibilityNextTextNavigationElement accessibilityPreviousTextNavigationElement We want to know whether skipping the line when provided with leading spaces is expected or a bug in UIKit.

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?

I’m trying to add the .header accessibility trait to a UISegmentedControl so that VoiceOver recognizes it accordingly. However, setting the trait using the following code doesn’t seem to have any effect: segmentControl.accessibilityTraits = segmentControl.accessibilityTraits.union(.header) Even after applying this, VoiceOver doesn’t announce it as a header. Is there any workaround or recommended approach to achieve this?

VoiceOver reads out all visible content on the screen, which is essential for visually challenged users. However, this raises a privacy concern—what if a user accidentally focuses on sensitive information, like a bank account password, and it gets read aloud? How can developers prevent VoiceOver from exposing confidential data while still maintaining accessibility? Are there best practices or recommended approaches to handle such scenarios effectively?

Good day! I have a long-term project ported all the way up from old Think C through many versions of Xcode. Its source files are encoded in "Western (Mac OS Roman)". Some of my error messages have characters outside the straight ASCII character set (i.e. "å"). The editor correctly displays these, but I get plenty of Illegal Character warnings and the messages do not display properly. I imagine there's a way to have seperate files of localized text for internationalized applications, but I am the only end-user of this application, and it used to just plain work in earlier Xcode versions. Furthermore, there must be developers throughout Europe who use such characters in string literals, just typing in their native languages, straight off their keyboards. I was thinking that there must be a Clang setting or something, but have been unable to find it, and an internet search turns up no solution except to cumbersomely escape each individual character. I can't imagine that a French programmer does that every time they want to type "è", "é", or "à"! Any help? (Disclaimer: I'm an English speaker and only use such characters whimsically, but want to keep them for legacy's sake.) Thanks.... p.s. using Xcode 15.3, and under Settings->Text Editing->Editing, "Western (Mac OS Roman)" is already selected as the default text encoding with "Convert existing files on save" checked.

The issue described here in this stack overflow conversation is still an issue today when it comes to the read back of the last 4 digits in the phone numbers for North American numbers as minus. Is there a solution other than overriding the accessibleLabel property?

I am seeing a strange issue where NSObject accessibilityRespondsToUserInteraction returns true on Simulator but false on device. Checking the same object on simulator with Accessibility inspector I see the object traits as image so why would it return true in that case? Are there any other way to check the the item might be accessibilityRespondsToUserInteraction OR Clickable beside that property and traits? (Or is it just another bug)

I have a TextField and entered for example "sg?!". At the TextField I set the modifier speechAlwaysIncludesPunctuation(). But when I activate VoiceOver the content of TextField is reading. The special characters don't read out. How can I fix this?

While editing the search text using the external keyboard (with VoiceOver on), if I try to navigate the to List using the keyboard, the focus jumps back to the search field immediately, preventing selection of list items. It's important to note that the voiceover navigation alone without a keyboard works as expected. It’s as if the List never gains focus—every attempt to move focus lands back on the search field. The code: struct ContentView: View { @State var searchText = "" let items = ["Apple", "Banana", "Cherry", "Date", "Elderberry", "Fig", "Grape"] var filteredItems: [String] { if searchText.isEmpty { return items } else { return items.filter { $0.localizedCaseInsensitiveContains(searchText) } } } var body: some View { if #available(iOS 16.0, *) { NavigationStack { List(filteredItems, id: \.self) { item in Text(item) } .navigationTitle("Fruits") .searchable(text: $searchText) } } else { NavigationView { List(filteredItems, id: \.self) { item in Text(item) } .navigationTitle("Fruits") .searchable(text: $searchText) } } } }

I’m trying to understand the best practice for assigning accessibilityTraits to a UITableViewCell that users can select from a list of options. In Apple’s first-party apps like Settings, I’ve noticed an inconsistent approach—some cells use the Button trait, while others simply announce the label along with the Selected trait when applicable, without any additional role like Button or Adjustable. So my question is: What is the most appropriate accessibility trait to use for a selectable table view cell that updates a selection (like a settings option)? Is using .button the right approach, or should we rely solely on .selected? Is there any user experience guideline from Apple that recommends one over the other? Would love to hear how others handle this for clarity and consistency in VoiceOver behavior.

In SwiftUI, the date picker component is breaking in colour contrast accessibility. Below code has been use to create date picker: struct ContentView: View { @State private var date = Date() @State private var selectedDate: Date = .init() var body: some View { let min = Calendar.current.date(byAdding: .day, value: 14, to: Date()) ?? Date() let max = Calendar.current.date(byAdding: .year, value: 4, to: Date()) ?? Date() DatePicker( "Start Date", selection: $date, in: min ... max, displayedComponents: [.date] ) .datePickerStyle(.graphical) .frame(alignment: .topLeading) .onAppear { selectedDate = Calendar.current.date(byAdding: .day, value: 14, to: Date()) ?? Date() } } } #Preview { ContentView() } attaching the screenshot of failure accessibility.

Hello, I'm currently unable to access App Store Connect. When I try to open https://appstoreconnect.apple.com, I receive the following error message: “appstoreconnect.apple.com is currently unable to handle this request.” I’ve tried the following steps, but the issue persists: Cleared browser cache and cookies Tried different browsers (Safari, Chrome) Attempted from multiple devices and networks Is this a known issue or is there any workaround available? Would appreciate any help or update on the current status. Thank you,
