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 have a view dynamically overlaid on a UITableView with proper padding (added when certain conditions are met). When VoiceOver focuses on a cell beneath this overlay, the focused element does not scroll into view. I’ve noticed similar behavior in Apple’s first-party Podcasts app. Please find the attached image for reference. How can I resolve this issue and ensure VoiceOver scrolls the focused cell into view?

I’m trying to set the accessibilityActivationPoint directly on a UITableViewCell so that VoiceOver activate on a specific button inside the cell. However, this approach doesn’t seem to work. Instead, when I override the accessibilityActivationPoint property inside the UITableViewCell subclass and return the desired point, it works as expected. Why doesn’t setting accessibilityActivationPoint directly on the cell work, but overriding it inside the cell does? Is there a recommended approach for handling this scenario? The following approach works, override var accessibilityActivationPoint: CGPoint { get { return convert(toggleSwitch.center, to: nil) } set{ super.accessibilityActivationPoint = newValue } } but setting accessibility point directly not works private func configureAccessibility() { isAccessibilityElement = true accessibilityLabel = titleLabel.text accessibilityTraits = .toggleButton accessibilityActivationPoint = self.convert(toggleSwitch.center, to: self) accessibilityValue = toggleSwitch.accessibilityValue }

I have a parent view containing 10 subviews. To control the VoiceOver navigation order, I set only a few elements in accessibilityElements. However, the remaining elements are not being focused or are completely inaccessible. Is this the expected behavior? If I only specify a subset of elements in accessibilityElements, does it exclude the rest? What’s the best way to ensure all elements remain accessible while customising the order?

SwiftUI provides the accessibilityCustomContent(_:_:) modifier to add additional accessibility information for an element. However, I couldn’t find a similar approach in UIKit. Is there a way to achieve this in UIKit?

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?

In VoiceOver, when using Group Navigation style, the cursor first focuses on the semantic group. To navigate inside the group, a two-finger swipe (left or right) can be used. This behavior works for default containers like the Navigation Bar, Tab Bar, and Tool Bar. How can I achieve the same behavior for a custom view? I tried setting accessibilityContainerType = .semanticGroup, but it only works for Mac Catalyst. Is there an equivalent approach for iOS?

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?

I’m currently focused on an element at the bottom of the screen. What is the proper way to quickly navigate to the top element? By default, there’s a four-finger single tap to move to the first element, but should I use the Rotor action instead to focus on the element I need? For example, in the Contacts app while adding a new contact, if I enter a value in a field at the bottom, there’s no quick way to directly save the contact. I have to manually navigate all the way to the top to tap the Done button, which feels a bit inconvenient. Is there a better way to handle this using VoiceOver?

I’ve tried implementing the accessibilityPerformMagicTap() method in a specific UIViewController, its view, and even in AppDelegate, but I am not receiving any callbacks. I directly overrode this method in the mentioned areas, but it never gets triggered when performing a magic tap. How can I properly observe and handle the accessibilityPerformMagicTap() action?

I’m currently exploring VoiceOver accessibility in iOS and looking for the best way to reduce the number of swipes required to navigate a UITableView. I’ve come across a couple of potential solutions but am unsure which is preferred. Solution 1: Grouping Subviews in Each Cell Combine all subviews inside a UITableViewCell into a single accessibility element. Provide a concise and meaningful accessibilityLabel. Use custom actions (UIAccessibilityCustomAction) or accessibilityActivationPoint to handle interactions on specific elements within the cell. Solution 2: Using UIAccessibilityContainerDataTableCell & UIAccessibilityContainerDataTable Implement UIAccessibilityContainerDataTable for structured table navigation. Make each cell conform to UIAccessibilityContainerDataTableCell, defining its row and column positions. However, I’m finding this approach a bit complex, and I need guidance on properly implementing these protocols. Additionally, in my case, VoiceOver is not navigating to Section 2—I’m not sure why. Questions: Which of these approaches is generally preferred for better VoiceOver navigation? How do I properly implement UIAccessibilityContainerDataTable so that all sections and rows are navigable? Any best practices or alternative recommendations? Would really appreciate any insights or guidance!

I've got a web app built with MusicKit that displays a list of songs. I have player controls for play, pause, skip next, skip, previous, toggle shuffle and set repeat mode. All of these work by using music. The play button, when nothing is playing and nothing is in the queue, will enqueue all the tracks and start playing with the below, for example: await music.setQueue({ songs, startPlaying: true }); I've implemented a progress slider based on feedback from the "playbackProgressDidChange" listener. Now, how in the world can I set the volume? This seems like it should be simple, but I am at a complete loss here. The docs say: "The volume of audio playback, which is set directly on the HTMLMediaElement as the HTMLMediaElement.volume property. This value ranges between 0, which would be muting the audio, and 1, which would be the loudest possible." Given that all my controls work off the music instance, I don't understand how I can do that. In this video from WWDC 2022, music web components are touched on briefly. These are also documented very sparsely. The volume docs are here. For the life of me, I can't even get the volume web component to display in the UI. It appears that MusicKit Web is hobbled compared to the native implementation, but surely adjusting volume shouldn't be that hard right? I'd appreciate any insight on how to do this, including how to get web components to work (in a Next JS app). Thanks.

I'm developing an ACME server to issue identity certificates to macOS/iOS devices for MDM attestation, following RFC 8555. Per RFC, the client creates an order, performs authorization, verifies the challenge, and finalizes the order by submitting a CSR to the CA. In my setup, the CA sometimes takes longer to issue the certificate (around 50 seconds). According to RFC 8555, if certificate issuance isn’t complete after the /finalize call, the server should respond with an "order" object with a "processing" status. The client should then send a POST-as-GET request to the order resource (e.g., /order/<order_id>) to check the current state. If the CA still hasn’t issued the certificate, the server should return the order object with the same "processing" status and include a "Retry-After" header, indicating when the client should retry. The client is expected to poll the order resource at this specified interval with POST-as-GET requests. However, it seems the Apple ACME client ignores the "Retry-After" header and instead returns the error: "Profile failed - Order status is processing, not yet valid" immediately upon the first poll response with "processing." Apple ACME client deviating from the RFC documentation. Has anyone found a reliable solution to this issue? Or does Apple supports asynchronous order finalization? Ref -https://datatracker.ietf.org/doc/html/rfc8555#:~:text=A%20request%20to%20finalize%20an%20order%20will%20result%20in%20error,to%20the%20%22certificate%22%20field%20of%20the%20order.%20%20Download%20the%0A%20%20%20%20%20%20certificate. To work around this, I’m holding the /finalize call until the CA issues the certificate. This works when issuance is quick (under 20 seconds), but if it takes more than that , the client times out. Interestingly, the Apple ACME client’s timeout appears shorter than the usual 60-second URLSession default.

Current Apple ACME Profile does not support EAB. Do you have any plan to support it?

I'm building a UIKit app that reads user's Apple Music library and displays it. In MusicKit there is the Artwork structure which I need to use to display artwork images in the app. Since I'm not using SwiftUI I cannot use the ArtworkImage view that is recommended way of displaying those images but the Artwork structure has a method that returns url for the image which can be used to read the image. The way I have it setup is really simple: extension MusicKit.Song { func imageURL(for cgSize: CGSize) -> URL? { return artwork?.url( width: Int(cgSize.width), height: Int(cgSize.height) ) } func localImage(for cgSize: CGSize) -> UIImage? { guard let url = imageURL(for: cgSize), url.scheme == "musicKit", let data = try? Data(contentsOf: url) else { return nil } return .init(data: data) } } Now, everytime I access .artwork property (so a lot of times) the main thread gets blocked and the console output gets bombared with messages like these: 2023-07-26 11:49:47.317195+0200 Plum[998:297199] [Artwork] Failed to create color analysis for artwork: <MPMediaLibraryArtwork: 0x289591590> with error; Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.mediaartworkd.xpc was invalidated: failed at lookup with error 159 - Sandbox restriction."

I am not planning to use it anywhere and if so it should be a computed async property so it doesn't block the caller. I know I can move the call to a background thread and that fixes the issue of blocking main thread but still the loading times for each artwork are terribly slow and that impacts the UX. SwiftUI's ArtworkImage loads the artworks much quicker and without the errors so there must be a better way to do it.
