NavigationSplitView, tvOS, and view focus
Hello, I have a SwiftUI application that uses NavigationSplitView. It's working great on iOS, iPad, and macOS. I decided to give it a try on tvOS. After it builds, it will not allow user interaction on the NavigationSplitView's sidebar. I've tried various view focus modifiers without any success. I'd also expect this to "just work" as default behavior. I have filed FB13447961 on this issue. Here is a distillation of the code that demonstrates the problem. Any ideas? Thank you. enum Category : String, CaseIterable { case first case second case third } enum Detail : String, CaseIterable { case one case two case three } struct DetailView : View { let category : Category? var body: some View { if let category { Text(category.rawValue) List(Detail.allCases, id: \.self) { detail in NavigationLink(value: detail) { Text(detail.rawValue) } } } else { Text("Select Category") } } } struct ContentView: View { // NOTE: If this category is set to something, it will show that category's detail. // The problem is that the NavigationSplitView sidebar does not have, nor does not // seem to be able to get focus. @State var category: Category? @State var path : [Detail] = [] var body: some View { NavigationSplitView { List(Category.allCases, id: \.self, selection: $category) { category in Text(category.rawValue) } } detail: { NavigationStack(path: $path) { DetailView(category: category) .navigationDestination(for: Detail.self) { detail in Text("\(detail.rawValue)") } } } } } #wwdc2023-10162 #wwdc20-10042

Significant scrolling lag when using .focused modifier in large LazyVStack/LazyHStack on tvOS
Summary: When using the new .focused modifier to track focus within a large LazyVStack or LazyHStack, we observe a major frame-rate drop and stuttering on Apple TV (1st and 2nd generation). Steps to Reproduce: Create a LazyVStack (or LazyHStack) displaying a substantial list of data models (e.g., 100+ GroupData items). Attach the .focused(::) modifier to each row, binding to an @FocusState variable of the same model type. Build and run on an Apple TV device or simulator. Scroll through the list using the remote. static func == (lhs: GroupData, rhs: GroupData) -> Bool { lhs.id == rhs.id } var id: String var name: String var subName: String var subGroup: [GroupData] = [] var logo: URL? } struct TestView: View { @FocusState var focusedGroup: GroupData? let groupsArr: [GroupData] var body: some View { ScrollView { LazyVStack { ForEach(groupsArr, id: \.id) { group in Button { } label: { GroupTestView(group: group) } .id(group.id) .focused($focusedGroup, equals: group) } } } } } struct GroupTestView: View { let group: GroupData var body: some View { HStack { KFImage.url(group.logo) .placeholder { Image(systemName: "photo") .opacity(0.2) .imageScale(.large) } .resizable() .scaledToFit() .frame(width: 70) VStack { Text(group.name) Text(group.subName) } } } } Expected Behavior Scrolling remains smooth (60 fps) regardless of list size. Focus updates without introducing visible lag. Observed Behavior Frame rate drops significantly when .focused is applied. Scrolling becomes visibly laggy, especially on older Apple TV hardware. Even when binding an @FocusState<String?> (storing only the id), performance improves slightly but remains suboptimal. Workarounds Tried Switched to @FocusState of type String to track only the ID of each group, this has helped but there is still a big performance decrease. Minimised view-body complexity and removed other modifiers. Verified that excluding .focused entirely restores smooth scrolling. Any guidance or suggestions would be greatly appreciated.

Getting ShinyTV Example to Work
I have downloaded the ShinyTV example to test simplified sign-in on tvOS since it is not working in my own app, and I am having the same issue there. After assigning my team to the sample app, the bundle ID updates with my team id. I copy the bundle ID into a file entitled "apple-app-site-association" with this format: { "webcredentials": { "apps": [ "{MyTeamID}.com.example.apple-samplecode.ShinyTV{MyTeamID}" ] } } I upload the file to my personal site, ensuring that the content type is application/json. I adjust the Associated Domain entitlement to: webcredentials:*.{personal-site.com}?mode=developer using the alternate mode to force it to load from my site, not the CDN. When I run the build on tvOS, and click the Sign In button, it fails with these errors: Failed to start session: Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 "Failed to prepare authorization requests" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"Missing associated web credentials domains\" UserInfo={NSLocalizedDescription=Missing associated web credentials domains}" ), NSLocalizedDescription=Failed to prepare authorization requests} Session failed: Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 "Failed to prepare authorization requests" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"Missing associated web credentials domains\" UserInfo={NSLocalizedDescription=Missing associated web credentials domains}" ), NSLocalizedDescription=Failed to prepare authorization requests} ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"(null)\"" )} Failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "Failed to prepare authorization requests" UserInfo={NSMultipleUnderlyingErrorsKey=( "Error Domain=com.apple.CompanionServices.CPSErrorDomain Code=205 \"Missing associated web credentials domains\" UserInfo={NSLocalizedDescription=Missing associated web credentials domains}" ), NSLocalizedDescription=Failed to prepare authorization requests} What am I missing here?

pas_panic_on_out_of_memory_error crash on tvOS 15.4 and 15.4.1

Apple TV 4k 3rd Gen recovery failures
Hello there I have got into a bit of an issue with the Apple TV 4k 3rd Gen with Ethernet . So I installed the iOS 26 beta to try out the new changes I usually do this on Apple TVs but in this case it has a bug where my apple music randomly skipped to the next songs . So after some bit of reading I got to know that the apple TV as a recovery mode which could be accessed by pressing home and pause/play buttons . After getting there I was required to bring an iPhone close to start the recovery process which I did but somehow that process always failed I tried to plug in the Ethernet cable since my apple TV is literally 3-5 inches away from my main router I even tried the recommended option of switching to a 2.4ghz connection but nothing worked . I would think that by apple getting rid of the USB ports on these things they had a reliable method of recovery in case of error because these are computers they are bound to fail at some point . So for now am stuck with a boot looping apple TV without a port and I don't even know how that too came about since the recovery process barely starts and fails. Ps am in Africa where we have no apple stores so we usually deal with our products ourselves

Correct formatting of webcredentials app id
I have been trying to add improved tvOS login using an Associated Domain and web credentials. In some places, I am seeing that the format is &lt;TEAM_ID&gt;.&lt;BUNDLE_ID&gt;, and in other places I am seeing &lt;APP_ID&gt;.&lt;BUNDLE_ID&gt;. I am having trouble getting both to work, but in order to properly troubleshoot, I want to make sure that I am using the correct identifier. Can someone give me a definitive answer? The documentation says app id, but I have seen Apple engineers in this forum say team id, and many other posts around the internet also saying team id.

What kind of feedback is available through tvOS Bluetooth HID?
first post here and this is kinda a long shot. I’m working on a custom keypad project for a young man with some mobility issues that unfortunately prevents gestrue and voice control as UI options. id like to see if I can pull track metadata via a Bluetooth connection into a custom keyboard with a small screen. I know hid doesn’t support this but I was hoping maybe the API for iOS’s blueprint remote app could be leveraged. I haven’t don’t much with Apple previousl. Usually Roku and Crestron implantations but I’m hoping to see if I can accomplish something with Apple, without needing to implement any IP connection.

UIDefines.h breaking tvOS on 26 in Tahoe
We have an app that optionally includes UIKit, and in Xcode 16.3 it builds just fine, but with Xcode 26 it fails because it cannot find UIDefines.h. Error: /Applications/Xcode-beta.app/Contents/Developer/Platforms/AppleTVOS.platform/Developer/SDKs/AppleTVOS26.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKitDefines.h:10:9: fatal error: 'UIUtilities/UIDefines.h' file not found I looked for it, and inside of Xcode 26 there is a new folder(SubFrameworks) inside of the TV Simulator that does not exist in 18 and it only has one thing in that folder and it's UIUtilities.framework. Reference path: /Applications/Xcode-beta.app/Contents/Developer/Platforms/AppleTVSimulator.platform/Developer/SDKs/AppleTVSimulator.sdk/System/Library/SubFrameworks/UIUtilities.framework/ Not sure how to get around this except to put in a bunch of new ifdefines maybe to deal with it, but it is weird that the subframeworks file is part of the issue. Anyone have any ideas besides copying the files over (doesn't work anyway)?

SwiftUI Bug on tvOS 18 – TextField Broken in Modals
Just noticed a bug in tvOS 18+: If you present a modal (.sheet or similar) that contains a TextField, click into the text field to select your text from keyboard, then press the Back button, the TextField becomes unclickable and we are not able to update the textfield again. This behavior didn’t happen in tvOS 17, so it seems to be a regression introduced in tvOS 18.3, tested only on silumator Repro steps: Present a modal with a TextField Focus and click the TextField Press the Back button to dismiss the keyBoard Try clicking the TextField → nothing happens (and textfield is full white) If anyone has a workaround, I’d love to hear it! struct ModalView: View { @State var text: String = "" var body: some View { TextField("", text: $text, prompt: Text("Prompt")) } } struct ContentView: View { @State var isModal: Bool = false var body: some View { NavigationView { ZStack { SwiftUI.Button.init { isModal = true } label: { Text("click") } } }.sheet(isPresented: $isModal) { ModalView() } } }

Is it possible to query the TV's current refresh rate?
I'm working on a media app that would like to be able to tell if the TV connected to tvOS is running at 59.94hz or 60.00hz, so it can optimize a video stream. It looks like the best I can currently do is to check if the user has Match Content Rate enabled, and based on that, when calling displayManager.preferredDisplayCriteria to change video modes, I could guess which rate their TV might be in. It's not very ideal, because not all TVs support both of these rates, and my request for 59.94 might end up as 60 and vice versa. I dug around and can't find any available method in UIScreen to get this info. The odd thing is, the data is right there in currentMode when I look in the debugger, but it seems to be in a private or undocumented class. Is there any way to get at it?

DNSServiceBrowse() callback receives error code -65570
Hi, I am trying to update an old prototype I made for tvOS using DNSServiceBrowse(). The target was tvOS 17. My old build from September 2023 still works fine: It can discover computers on the same local network as the Apple TV (simulator). However, now that I am using Xcode 16, the DNSServiceBrowse() callback (of type DNSServiceBrowseReply) receives the error code: -65570. The call to DNSServiceBrowse() itself returns no error, neither does the following call to DNSServiceProcessResult() — which actually triggers the call of the callback. I found nowhere in the Internet any list of possible error codes received by the callback, so I have no idea what it means. So, my first question is: What does this error code mean? (And is there any list of the possible errors somewehere, with their meaning?) Since it was a prototype, I have no provisioning profile defined for it. Could that be related to the issue? Since I will make a real app out that prototype (targeting tvOS 18), I will have to define a provisioning profile for it. Would a provisioning profile for the app solve the issue? If yes, are there any requirements for that profile that I should take into account to solve the issue? Thank you in advance for any help, Marc

Multiplatform Target: Distill failed on tvOS builds
Building my multiplatform target, works great for iOS, visionOS, MacOS. tvOS builds fine, if I do not include any of the items in the .xcassets file. I have attempted to add a second .xcassets file for just tvOS, but Xcode will not detect the second .xcassets if created manually, and will just "spin" when adding via the add file menu option. If I add tvOS to the target membership for any of the .xcassets items (Xcode applies that target membership for ALL items in the .xcassets) we then we get the distill failed error. The issue will sporadically be solved by removing the visionOS app icon from the .xcassets file and building that way, but it is not a perfect solution, as it does not work every time. If there is a more targeted "membership options" that doesn't apply .xcassets wide, that would probably be the simplest solution.

How to Properly Integrate Google IMA SDK for Pre-roll, Mid-roll, and Post-roll Ads in a tvOS App using TVJS and Swift?
I'm working on a tvOS application that plays video content using TVMLKit/TVJS. I'm trying to integrate Google IMA SDK to show pre-roll, mid-roll, and post-roll ads in my app. Here’s what I’ve done so far: Video playback is handled through JavaScript in application.js. Ads are managed in Swift using Google IMA SDK. I use the evaluateJavaScript bridge to control video playback from Swift. I pause and resume the TVJS player (Player object) using a function like startPlayingVideo(value) from Swift based on the ad lifecycle. Current Flow: When the video is about to start, I call loadAds() from JS. This presents a Swift ViewController that handles IMA ad requests. On adsManagerDidRequestContentPause, I pause the video using JS via the bridge. On adsManagerDidRequestContentResume, I resume the video. The Issue: This setup doesn't behave consistently: Sometimes the ad plays in the background and video started playing as well but can not see the ad. Not able to see the post-roll ads Relevant Code Snippets: application.js function startPlayingVideo(value) { if (playerReference != undefined) { if (value == true) { playerReference.play(); else { playerReference.pause(); } } } function playVideo(videoURL) { setup playerReference, push mediaItem, etc. loadAds(); player.present(); } AppDelegate.swift let loadAds: @convention(block) () -\> Void = { DispatchQueue.main.async { let adManagerVC = ViewController() AppDelegate.tvController?.navigationController.present(adManagerVC, animated: true) } } let updateVideoPlayTime: @convention(block) (Double) -\> Void = { time in CustomContentPlayhead.shared.currentTime = TimeInterval(time) } ViewController.swift func adsManagerDidRequestContentPause(\_ adsManager: IMAAdsManager) { showAdUI() playerViewController.player?.pause() } func adsManagerDidRequestContentResume(\_ adsManager: IMAAdsManager) { hideAdUI() // Expecting JS video to resume via bridge } And yeah my IMSDK Implementation is working fine if I am using it with swift AVPlayer. What I Need Help With: Best practice for coordinating video playback between JS (Player) and Swift (IMAAdsManager). How can I sync the playhead reliably between JS and Swift? Is there a better way to pause/resume TVJS player from Swift during ad lifecycle? How to reliably insert mid-roll ads when the playback is primarily controlled in JS? Any insights, code examples, or recommended architecture improvements would be greatly appreciated!

tvOS App Icon & Top Shelf Image
ISSUE: Warning: None of the input catalogs contained a matching App Icon & Top Shelf Image brand assets collection named "AppIcon" INFORMATION: So I currently have my app published and it works for iOS, and visionOS. (iPhone, iPad, Mac & Apple Vision Pro) There is one target for all OS versions. I have recently updated it to work with tvOS, however upon building I run into the warning listed at the top of this post. I have the following within the project: 'AppIcon.icon' (from the new icon composer for iOS, macOS and watchOS) And within .xcassets: 'AppIcon' (which contains the majority of the icons) 'Brand Assets' Folder (created by right click, tvOS, New tvOS App Icon and Top Shelf Image; which contains these icons in layers and the correct sizes) Brand Assets retains the names created by Xcode, App Icon - App Store, App Icon, Top Shelf Image Wide, Top Shelf Image In "General" in the target, I have AppIcon, still listed as the AppIcon name. Adding a second entry here for just tvOS does not resolve my issue, our could be that I do not what to call it so it can properly find it. QUESTION: What am I missing so that the build process detects these images properly and completes a successful build for tvOS? I am assuming I need to add options to the App Icons and Launch Screens area, but what is the name I place here for tvOS? SCREENSHOTS:

tvOS 26 issue: Please bring back passcode-locked apps — disappearing apps and shared restrictions make Apple TV frustrating for families
I recently updated to tvOS 26 on my Apple TV 4K (1st generation) and was disappointed to find that apps I restrict no longer appear at all. In earlier versions, restricted apps would still be visible and simply prompt for a passcode — this was much more convenient for adults in the household. Now, if I restrict apps for my children, they disappear completely. To use them again, I have to go deep into settings, turn restrictions off, and even recreate the passcode each time, which is frustrating and impractical for daily use. I also tried adding a Kids user account, but most restrictions still apply system-wide. Only the Apple TV app behaves differently between users. This makes switching between parent and child accounts nearly pointless for managing access. Please consider one or both of the following: 1. Bring back the passcode-on-launch behavior for restricted apps (instead of hiding them). 2. Give each user their own isolated settings environment, like how profiles work on iOS/iPadOS or even a fresh Apple TV—this way, restrictions, home screen, and app access could be personalized. Families are a huge part of the Apple TV audience, and these recent changes have made it much harder to use the device in a shared household. Thank you!

tvOS AVQueuePlayer Now Playing Info in Control Center?
I have a music app I'm developing and having a weird issue where I can see now playing info for every other platform than tvOS. As far as I can tell I have correctly configured the MPNowPlayingInfoCenter MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo MPNowPlayingInfoCenter.default().playbackState = .playing Are there any extra requirements to get my app's now-playing info showing in control center on tvOS? Another strange issue that might be related is I can use the apple TV remote to pause audio but not resume playback, so I feel like there's something I'm missing about registering audio playback on tvOS specifically.

Wireless audio calibration with AirPlay speakers
Hey, I have AirPlay speakers that I want to use as permanent speakers on my Apple TV. It is possible since tvOS 26. I want to delete the delay from the connection to the speakers and tried out the wireless audio calibration, but then the TV speakers go on and it only works there, not on the speakers. Does anyone have a solution?

Will 3rd party speakers support eARC/ARC on tvOS 26?
tvOS 26 rolls out the feature to set every AirPlay speaker as permanent in the settings. Is there a possibility to setup eARC like with the HomePods for other devices connected to a TV or will this stay a HomePod only feature?

pas_panic_on_out_of_memory_error crash on tvOS 15.4 and 15.4.1
Hi there, I'm experiencing several crashes on JavaScriptCore pas_panic_on_out_of_memory_error, only on devices with tvOS 15.4 and 15.4.1.

Apple TV 4k 3rd Gen recovery failures
Hello there I have got into a bit of an issue with the Apple TV 4k 3rd Gen with Ethernet . So I installed the iOS 26 beta to try out the new changes I usually do this on Apple TVs but in this case it has a bug where my apple music randomly skipped to the next songs . So after some bit of reading I got to know that the apple TV as a recovery mode which could be accessed by pressing home and pause/play buttons . After getting there I was required to bring an iPhone close to start the recovery process which I did but somehow that process always failed I tried to plug in the Ethernet cable since my apple TV is literally 3-5 inches away from my main router I even tried the recommended option of switching to a 2.4ghz connection but nothing worked . I would think that by apple getting rid of the USB ports on these things they had a reliable method of recovery in case of error because these are computers they are bound to fail at some point . So for now am stuck with a boot looping apple TV without a port and I don't even know how that too came about since the recovery process barely starts and fails. Ps am in Africa where we have no apple stores so we usually deal with our products ourselves

Correct formatting of webcredentials app id
I have been trying to add improved tvOS login using an Associated Domain and web credentials. In some places, I am seeing that the format is &lt;TEAM_ID&gt;.&lt;BUNDLE_ID&gt;, and in other places I am seeing &lt;APP_ID&gt;.&lt;BUNDLE_ID&gt;. I am having trouble getting both to work, but in order to properly troubleshoot, I want to make sure that I am using the correct identifier. Can someone give me a definitive answer? The documentation says app id, but I have seen Apple engineers in this forum say team id, and many other posts around the internet also saying team id.

What kind of feedback is available through tvOS Bluetooth HID?
first post here and this is kinda a long shot. I’m working on a custom keypad project for a young man with some mobility issues that unfortunately prevents gestrue and voice control as UI options. id like to see if I can pull track metadata via a Bluetooth connection into a custom keyboard with a small screen. I know hid doesn’t support this but I was hoping maybe the API for iOS’s blueprint remote app could be leveraged. I haven’t don’t much with Apple previousl. Usually Roku and Crestron implantations but I’m hoping to see if I can accomplish something with Apple, without needing to implement any IP connection.

UIDefines.h breaking tvOS on 26 in Tahoe
We have an app that optionally includes UIKit, and in Xcode 16.3 it builds just fine, but with Xcode 26 it fails because it cannot find UIDefines.h. Error: /Applications/Xcode-beta.app/Contents/Developer/Platforms/AppleTVOS.platform/Developer/SDKs/AppleTVOS26.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKitDefines.h:10:9: fatal error: 'UIUtilities/UIDefines.h' file not found I looked for it, and inside of Xcode 26 there is a new folder(SubFrameworks) inside of the TV Simulator that does not exist in 18 and it only has one thing in that folder and it's UIUtilities.framework. Reference path: /Applications/Xcode-beta.app/Contents/Developer/Platforms/AppleTVSimulator.platform/Developer/SDKs/AppleTVSimulator.sdk/System/Library/SubFrameworks/UIUtilities.framework/ Not sure how to get around this except to put in a bunch of new ifdefines maybe to deal with it, but it is weird that the subframeworks file is part of the issue. Anyone have any ideas besides copying the files over (doesn't work anyway)?

SwiftUI Bug on tvOS 18 – TextField Broken in Modals
Just noticed a bug in tvOS 18+: If you present a modal (.sheet or similar) that contains a TextField, click into the text field to select your text from keyboard, then press the Back button, the TextField becomes unclickable and we are not able to update the textfield again. This behavior didn’t happen in tvOS 17, so it seems to be a regression introduced in tvOS 18.3, tested only on silumator Repro steps: Present a modal with a TextField Focus and click the TextField Press the Back button to dismiss the keyBoard Try clicking the TextField → nothing happens (and textfield is full white) If anyone has a workaround, I’d love to hear it! struct ModalView: View { @State var text: String = "" var body: some View { TextField("", text: $text, prompt: Text("Prompt")) } } struct ContentView: View { @State var isModal: Bool = false var body: some View { NavigationView { ZStack { SwiftUI.Button.init { isModal = true } label: { Text("click") } } }.sheet(isPresented: $isModal) { ModalView() } } }

Is it possible to query the TV's current refresh rate?
I'm working on a media app that would like to be able to tell if the TV connected to tvOS is running at 59.94hz or 60.00hz, so it can optimize a video stream. It looks like the best I can currently do is to check if the user has Match Content Rate enabled, and based on that, when calling displayManager.preferredDisplayCriteria to change video modes, I could guess which rate their TV might be in. It's not very ideal, because not all TVs support both of these rates, and my request for 59.94 might end up as 60 and vice versa. I dug around and can't find any available method in UIScreen to get this info. The odd thing is, the data is right there in currentMode when I look in the debugger, but it seems to be in a private or undocumented class. Is there any way to get at it?

DNSServiceBrowse() callback receives error code -65570
Hi, I am trying to update an old prototype I made for tvOS using DNSServiceBrowse(). The target was tvOS 17. My old build from September 2023 still works fine: It can discover computers on the same local network as the Apple TV (simulator). However, now that I am using Xcode 16, the DNSServiceBrowse() callback (of type DNSServiceBrowseReply) receives the error code: -65570. The call to DNSServiceBrowse() itself returns no error, neither does the following call to DNSServiceProcessResult() — which actually triggers the call of the callback. I found nowhere in the Internet any list of possible error codes received by the callback, so I have no idea what it means. So, my first question is: What does this error code mean? (And is there any list of the possible errors somewehere, with their meaning?) Since it was a prototype, I have no provisioning profile defined for it. Could that be related to the issue? Since I will make a real app out that prototype (targeting tvOS 18), I will have to define a provisioning profile for it. Would a provisioning profile for the app solve the issue? If yes, are there any requirements for that profile that I should take into account to solve the issue? Thank you in advance for any help, Marc

Multiplatform Target: Distill failed on tvOS builds
Building my multiplatform target, works great for iOS, visionOS, MacOS. tvOS builds fine, if I do not include any of the items in the .xcassets file. I have attempted to add a second .xcassets file for just tvOS, but Xcode will not detect the second .xcassets if created manually, and will just "spin" when adding via the add file menu option. If I add tvOS to the target membership for any of the .xcassets items (Xcode applies that target membership for ALL items in the .xcassets) we then we get the distill failed error. The issue will sporadically be solved by removing the visionOS app icon from the .xcassets file and building that way, but it is not a perfect solution, as it does not work every time. If there is a more targeted "membership options" that doesn't apply .xcassets wide, that would probably be the simplest solution.

tvOS 26 removes ability to restrict apps with passcode
Please make sure this feature gets placed back. Parents need a way to provide the ability for kids to watch and not watch at their discretion. The new system doesn’t allow this to happen. Are there any workarounds?

How to Properly Integrate Google IMA SDK for Pre-roll, Mid-roll, and Post-roll Ads in a tvOS App using TVJS and Swift?
I'm working on a tvOS application that plays video content using TVMLKit/TVJS. I'm trying to integrate Google IMA SDK to show pre-roll, mid-roll, and post-roll ads in my app. Here’s what I’ve done so far: Video playback is handled through JavaScript in application.js. Ads are managed in Swift using Google IMA SDK. I use the evaluateJavaScript bridge to control video playback from Swift. I pause and resume the TVJS player (Player object) using a function like startPlayingVideo(value) from Swift based on the ad lifecycle. Current Flow: When the video is about to start, I call loadAds() from JS. This presents a Swift ViewController that handles IMA ad requests. On adsManagerDidRequestContentPause, I pause the video using JS via the bridge. On adsManagerDidRequestContentResume, I resume the video. The Issue: This setup doesn't behave consistently: Sometimes the ad plays in the background and video started playing as well but can not see the ad. Not able to see the post-roll ads Relevant Code Snippets: application.js function startPlayingVideo(value) { if (playerReference != undefined) { if (value == true) { playerReference.play(); else { playerReference.pause(); } } } function playVideo(videoURL) { setup playerReference, push mediaItem, etc. loadAds(); player.present(); } AppDelegate.swift let loadAds: @convention(block) () -\> Void = { DispatchQueue.main.async { let adManagerVC = ViewController() AppDelegate.tvController?.navigationController.present(adManagerVC, animated: true) } } let updateVideoPlayTime: @convention(block) (Double) -\> Void = { time in CustomContentPlayhead.shared.currentTime = TimeInterval(time) } ViewController.swift func adsManagerDidRequestContentPause(\_ adsManager: IMAAdsManager) { showAdUI() playerViewController.player?.pause() } func adsManagerDidRequestContentResume(\_ adsManager: IMAAdsManager) { hideAdUI() // Expecting JS video to resume via bridge } And yeah my IMSDK Implementation is working fine if I am using it with swift AVPlayer. What I Need Help With: Best practice for coordinating video playback between JS (Player) and Swift (IMAAdsManager). How can I sync the playhead reliably between JS and Swift? Is there a better way to pause/resume TVJS player from Swift during ad lifecycle? How to reliably insert mid-roll ads when the playback is primarily controlled in JS? Any insights, code examples, or recommended architecture improvements would be greatly appreciated!

tvOS App Icon & Top Shelf Image
ISSUE: Warning: None of the input catalogs contained a matching App Icon & Top Shelf Image brand assets collection named "AppIcon" INFORMATION: So I currently have my app published and it works for iOS, and visionOS. (iPhone, iPad, Mac & Apple Vision Pro) There is one target for all OS versions. I have recently updated it to work with tvOS, however upon building I run into the warning listed at the top of this post. I have the following within the project: 'AppIcon.icon' (from the new icon composer for iOS, macOS and watchOS) And within .xcassets: 'AppIcon' (which contains the majority of the icons) 'Brand Assets' Folder (created by right click, tvOS, New tvOS App Icon and Top Shelf Image; which contains these icons in layers and the correct sizes) Brand Assets retains the names created by Xcode, App Icon - App Store, App Icon, Top Shelf Image Wide, Top Shelf Image In "General" in the target, I have AppIcon, still listed as the AppIcon name. Adding a second entry here for just tvOS does not resolve my issue, our could be that I do not what to call it so it can properly find it. QUESTION: What am I missing so that the build process detects these images properly and completes a successful build for tvOS? I am assuming I need to add options to the App Icons and Launch Screens area, but what is the name I place here for tvOS? SCREENSHOTS:

tvOS 26 issue: Please bring back passcode-locked apps — disappearing apps and shared restrictions make Apple TV frustrating for families
I recently updated to tvOS 26 on my Apple TV 4K (1st generation) and was disappointed to find that apps I restrict no longer appear at all. In earlier versions, restricted apps would still be visible and simply prompt for a passcode — this was much more convenient for adults in the household. Now, if I restrict apps for my children, they disappear completely. To use them again, I have to go deep into settings, turn restrictions off, and even recreate the passcode each time, which is frustrating and impractical for daily use. I also tried adding a Kids user account, but most restrictions still apply system-wide. Only the Apple TV app behaves differently between users. This makes switching between parent and child accounts nearly pointless for managing access. Please consider one or both of the following: 1. Bring back the passcode-on-launch behavior for restricted apps (instead of hiding them). 2. Give each user their own isolated settings environment, like how profiles work on iOS/iPadOS or even a fresh Apple TV—this way, restrictions, home screen, and app access could be personalized. Families are a huge part of the Apple TV audience, and these recent changes have made it much harder to use the device in a shared household. Thank you!

tvOS AVQueuePlayer Now Playing Info in Control Center?
I have a music app I'm developing and having a weird issue where I can see now playing info for every other platform than tvOS. As far as I can tell I have correctly configured the MPNowPlayingInfoCenter MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo MPNowPlayingInfoCenter.default().playbackState = .playing Are there any extra requirements to get my app's now-playing info showing in control center on tvOS? Another strange issue that might be related is I can use the apple TV remote to pause audio but not resume playback, so I feel like there's something I'm missing about registering audio playback on tvOS specifically.
