SwiftUI tvOS Accessibility VoiceOver - prevent reading all items in ScrollView over and over
Hi, I'm trying to fix tvOS view for VoiceOver accessibility feature: TabView { // 5 tabs Text(title) Button(play) ScrollView { // Live LazyHStack { 200 items } } ScrollView { // Continue watching LazyHStack { 500 items } } } When the view shows up VoiceOver reads: "Home tab 1 of 5, Item 2" - not sure why it reads Item 2 of the first cell in scroll view, maybe beacause it just got loaded by LazyHStack. VocieOver should only read "Home tab 1 of 5" When moving focus to scroll view it reads: "Live, Item 1" and after slight delay "Item 1, Item 2, Item 3, Item 4" When moving focus to second item it reads: "Item 2" and after slight delay "Item 1, Item 2, Item 3, Item 4" When moving focus to third item it reads: "Item 3" and after slight delay "Item 1, Item 2, Item 3, Item 4" It should be just reading what is focused, idealy just "Live, Item 1, 1 of 200" then after moving focus on item 2 "Item 2, 2 of 200" this time without the word "Live" because we are on the same scroll view (the same horizontal list) Currently the app is unusable, we have visually impaired testers and this rotor reading everything on the screen is totaly confusing, because users don't know where they are and what is actually focused. This is a video streaming app and we are streaming all the time, even on home page in background, binge plays one item after another, usually there is never ending Live stream playing, user can switch TV channel, but we continue to play. Voice over should only read what's focused after user interaction. Original Apple TV app does not do that, so it cannot be caused by some verbose accessibility settings. It reads correctly only focused item in scrolling lists. How do I disable reading content that is not focused? I tried: .accessibilityLabel(isFocused ? title : "") .accessibilityHidden(!isFocused) .accessibilityHidden(true) - tried on various levels in view hierarchy .accessiblityElement(children: .ignore) - even focused item is not read back by voice over .accessiblityElement(children: .ignore) - even focused item is not read back by voice over .accessiblityElement(children: .contain) - tried on various levels in view hierarchy .accessiblityElement(children: .combine) - tried on various levels in view hierarchy .accessibilityAddTraits(.isHeader) - tried on various levels in view hierarchy .accessibilityRemoveTraits(.isHeader) - tried on various levels in view hierarchy // the last 2 was basically an attempt to hack it .accessibilityRotor("", ranges []) - another hack that I tried on ScrollView, LazyHStack, also on top level view. 50+ other attempts at configuring accessibility tags attached to views. I have seen all the accessibility videos, tried all sample code projects, I haven't found a solution anywhere, internet search didn't find anything, AI didn't help as it can only provide code that someone else wrote before. Any idea how to fix this? Thanks.

XPC listener initialized in System Extesnion invalidates incoming connection under certain conditions
I found a problem where a process tries to connect to System Extension and connection is invalidated. XPC listener has to be disposed and initialized again. This happens when System Extension executes tasks in following order: NSXPCListener initialized NSXPCListener.resume() NSProvider.startSystemExtensionMode() Result: Connection is invalidated and not only that the client has to retry connection, nut also System Extension must reinitialize listener (execute step 1 and 2). However if I call NSProvider.startSystemExtensionMode() NSXPCListener initialized NSXPCListener.resume() It works as expected and even if the connection is invalidated/interrupted, client process can always reconnect and no other action is necessary in System Extension (no need to reinitialize XPC listener), In Apple docs about NSProvider.startSystemExtensionMode() it says that this method starts handling request, but in another online article written by Scott Knight I found that startSystemExtensionMode() also starts listener server. Is that right? PLease could you add this info into the docs if it is so? https://knight.sc/reverse%20engineering/2019/08/24/system-extension-internals.html I would like to use following logic: Call NSProvider.startSystemExtensionMode() only under certain circumstances - I have received some configuration that I need to process and do some setup. If I don't receive it, there is no reason to call startSystemExtensionMode() yet, I don't need to handle handleNewFlow() yet. Connect XPC client to System Extension under certain conditions. Ideally communicate with client even though System Extension is not handling network requests yet, that is without receiving handleNewFlow(). Basically I consider XPC and System Extension handling network requests as separate things. Is that correct, are they separate and independent? Does XPC communication really depend on calling startSystemExtensionMode()? Another potential issue: Is it possible that XPC listener fails to validate connection when client tries to connect before System Extension manages to complete init and park the main thread in CFRunLoop? Note: These querstions arose mostly from handling upgrades of System Extension (extension is already running, network filter is created and is connected and new version of the app upgrades System Exension). Thanks.

tvOS 26 - AVPlayer.preventsDisplaySleepDuringVideoPlayback not working
Hi guys, after updating to tvOS 26 it is not possible to disable screensaver using AVPlayer.preventsDisplaySleepDuringVideoPlayback. We are streaming TV programs continuously and when player is in full creen we disable screensaver by setting preventsDisplaySleepDuringVideoPlayback = true When leaving player screen and navigating to Home or EPG where player continues to play in the background we set preventsDisplaySleepDuringVideoPlayback = false to enable screen saver in which case after set time screensaver activates. Disabling screensaver appears to be working only when starting the app for the first time, but when making the first transition out of the player and calling preventsDisplaySleepDuringVideoPlayback = false for the first time, then any subsequent change of preventsDisplaySleepDuringVideoPlayback to true has no effect. Result is that player is playing in full screen, but after set period (e.g. 2 minutes) screen saver activates, which is very bad user experience making TV app unusable. I tried using Xcode 26 and targetting tvOS 17 and higher. I installed Xcode 16.4 and rebuilt the app, but I see the same problem with screensaver. Xcode 16.4 and tvOS 17 target worked before. It appears to be related to tvOS 26 not to SDK itself. Is there perhaps a new API to disable screensaver? Is preventsDisplaySleepDuringVideoPlayback obsolete or could it be intention to disallow developers disabling screensaver? Do we need to notify all users to set screensaver time to higher value or Never if they want to watch TV for all day without touching remote? Not sure if it is a bug in tvOS 26 or purposely changed behavior. Does anybody know? Thanks.
