Hi, just generated a HDR10 MVHEVC file, mediainfo is below: Color range : Limited Color primaries : BT.2020 Transfer characteristics : PQ Matrix coefficients : BT.2020 non-constant Codec configuration box : hvcC+lhvC then generate the segment files with below command: mediafilesegmenter --iso-fragmented -t 4 -f av_1 av_new_1.mov then upload the segment files and prog_index.m3u8 to web server. just find that can not play the HLS stream on Safari... the url is http://ip/vod/prog_index.m3u8 just checked that if i remove the tag Transfer characteristics : PQ when generating the MVHEVC file. above same mediafilesegmenter command and upload the files to web server. the new version of HLS stream is can play on Safari... Is there any way to play HLS PQ video on Safari. thanks.

Hello, I use Preview to quickly test functionalities. However I found that the unified logging does not output to Preview console. So I had to do both log.debug and print. Is there a way to enable logging to Preview console?

Hi, just find that I can not play 3D movie stream: MV-HEVC/UHD/Dolby Vision/Dolby Digital/Dolby Atmos(website is https://developer.apple.com/streaming/examples) when I click View 3D example(fMP4), have below issue: my MacOS is 14.4.1 and M2 chip.

Hi everyone, I wanted to ask if anybody knows what the current status is about the declaration of required reasons APIs. Before May 1, when I uploaded a new build to the App Store Connect and added it to a group with external testers, I got a notification by email like the following: ITMS-91053: Missing API declaration - Your app’s code in the [...] file references one or more APIs that require reasons, including the following API categories: NSPrivacyAccessedAPICategoryDiskSpace. While no action is required at this time, starting May 1, 2024, when you upload a new app or app update, you must include a NSPrivacyAccessedAPITypes array in your app’s privacy manifest to provide approved reasons for these APIs used by your app’s code. In an article published by Apple (https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_use_of_required_reason_api) it is even statet that that after May 1, apps that do not comply are not accepted by the App Store Connect. According to my interpretation, even the upload should be rejected. I am currently in the process to add a privacy manifest and add the declarations. For testing purposes, I wanted to add the declarations step by step and see where I still need to fix anything. My problem is, that the warnings by apple are not beeing sent anymore. I have uploaded a new build after May 1 with no privacy manifest and therefore no API declarations, it was accepted by App Store Connect and even passed the review for an external testers group. Does anybody have information about the following questions? Did Apple shift the deadline? How can I trigger the warning emails again so that I know what to fix and see, when my app is compliant? Thanks in advance!

It seems like this may have been an issue for a while based on what I've seen, but I have added a toolbar item to a textfield keyboard and it doesn't show. The only way I can get it to show is by opening the keyboard, typing something, closing the keyboard, and then reopening it. Anyone have a workaround for this? It's like Apple purposely wants to make it difficult to close the keyboard. TextField("Something here...", text: $text, axis: .vertical) .multilineTextAlignment(.leading) .toolbar { ToolbarItemGroup(placement: .keyboard, content: { Button("Close") { } }) }

I have recently started using apple shortcuts to connect to a server to control a remote device. This remote device replies using JSON and depending on the request, it replies with a different status message. I would like to be able to read the reply in the shortcut and change the icon and/or the colour of the shortcut on the home screen depending on the reply. This could be used for locking a door where the reply indicates if the door is locked/unlocked by way of a closed/open padlock or by changing the background colour of the shortcut.

I'm developing an Apple TV OS app using SwiftUI. I'm encountering an issue with the color of the tab item. I want the color of the tab item to turn green when focused; for instance, when the tab item is selected, its background color should be green. Below is my current code, but it's not working. I've tried several other approaches, but none have worked. struct ContentView: View { @State private var selectedTab = 0 var body: some View { ZStack(alignment: .topLeading){ TabView(selection: $selectedTab) { HomeView() .tabItem { AppColors.gradientColor1 Label("Home", image: "home-dash") } .tag(0) ProductsView() .tabItem { Label("Products", image: "open box-search") } .tag(1) SearchView() .tabItem { Label("Search", image: "search") } .tag(2) } .accentColor(Color.green) .background(.black) Image("amazontabbarlogo") } } }

How can a programs be launched at startup if it is not in Launch Options and Launch Daemons/Agents? Spotify, for example.

If my app utilized the RoomPlan api to create a parametric representation of the room, would it open on iPhones that don’t have lidars? I‘m aware the iPhone models that are equipped with lidar are iPhone 12 Pro & Pro Max, iPhone 13 Pro & Pro Max, iPhone 14 Pro & Pro Max, and iPhone 15 Pro & Pro Max.

I was following the Swiftui tutorial at section 6 (https://developer.apple.com/tutorials/swiftui/creating-and-combining-views) to use a circle image to create an overlapping effect on the map. Turns out that when using a GeometryReader, the bottom padding was not working at all: VStack{ MapView().frame(height:300) CircleImage() .offset(y: -130) .padding(.bottom, -130) VStack(alignment:.leading){ Text( "Turtle Rock" ) .font( .title ) HStack { Text( "Joshua Tree National Park" ) .font( .subheadline ) Spacer() Text( "California" ) .font( .subheadline ) } }.padding(/*@START_MENU_TOKEN@*/10/*@END_MENU_TOKEN@*/) } This is the code for the CicleImage view: GeometryReader(content: { geometry in let _ = print( geometry.size.width ) AsyncImage( url: URL( string: "https://cms.rationalcdn.com/v3/assets/blteecf9626d9a38b03/bltf5486c52361f2012/6144fafd39dff133fc23de9f/img-ios.png" ) ) .frame(width: geometry.size.width) .clipShape( Circle() ).overlay{ Circle().stroke( .white, lineWidth: 4 ) }.shadow( radius: 7 ) })

Is it possible to create a material that behaves the same as AR ground plane, but in a NON-AR setup? Any help appreciated.

My Macbook Air mid-2013 model running MacOS Big Sur 11.7.10 has its system preference broken. The padlock to make changes doesn't do anything when clicked and so does every other tab or setting. Now, I can get into panels like Sound or Accessibilities, but everything that I SHOULD be able to do within them just... doesn't work. Nothing happens when I click on them. It's like they're just images.

Hi all, I need some help debugging some code I wrote. Just as a preface, I'm an extremely new VR/AR developer and also very new to using ARKit + RealityKit. So please bear with me :) I'm just trying to make a simple program that will track an image and place an entity on it. The image is tracked correctly, but the moment the program recognizes the image and tries to place an entity on it, the program crashes. Here’s my code: VIEWMODEL CODE: Observable class ImageTrackingModel { var session = ARKitSession() // ARSession used to manage AR content var imageAnchors = [UUID: Bool]() // Tracks whether specific anchors have been processed var entityMap = [UUID: ModelEntity]() // Maps anchors to their corresponding ModelEntity var rootEntity = Entity() // Root entity to which all other entities are added let imageInfo = ImageTrackingProvider( referenceImages: ReferenceImage.loadReferenceImages(inGroupNamed: "referancePaper") ) init() { setupImageTracking() } func setupImageTracking() { if ImageTrackingProvider.isSupported { Task { try await session.run([imageInfo]) for await update in imageInfo.anchorUpdates { updateImage(update.anchor) } } } } func updateImage(_ anchor: ImageAnchor) { let entity = ModelEntity(mesh: .generateSphere(radius: 0.05)) // THIS IS WHERE THE CODE CRASHES if imageAnchors[anchor.id] == nil { rootEntity.addChild(entity) imageAnchors[anchor.id] = true print("Added new entity for anchor \(anchor.id)") } if anchor.isTracked { entity.transform = Transform(matrix: anchor.originFromAnchorTransform) print("Updated transform for anchor \(anchor.id)") } } } APP: @main struct MyApp: App { @State var session = ARKitSession() @State var immersionState: ImmersionStyle = .mixed private var viewModel = ImageTrackingModel() var body: some Scene { WindowGroup { ModeSelectView() } ImmersiveSpace(id: "appSpace") { ModeSelectView() } .immersionStyle(selection: $immersionState, in: .mixed) } } Content View: RealityView { content in Task { viewModel.setupImageTracking() } } //Im serioulsy so clueless on how to use this view

Hello, I'll be objective: when I compile any APP in my XCode and transfer the APP to my iPhone, including the test APP "Hello world!", whether via network or USB cable, when I open the APP it simply doesn't work and the iPhone crashes. Only that. My XCode is 15.3, iPhone 14 Pro Max, IOS 17.5, macOS latest version.

I am using @AppStorage in a model object (see code below that works as expected). class ModelObject { static let shared = ModelObject() @AppStorage("enhanced") var scriptPickers: Bool = true var defaultDependentValue: String { scriptPickers ? "Enhanced" : "NOT enhanced" } } struct ContentView: View { @AppStorage("enhanced") var scriptPickers: Bool = true var body: some View { VStack { Toggle(isOn: $scriptPickers, label: { Text("userDefault val") }) Text("value: \(ModelObject.shared.defaultDependentValue)") } } } Now I want to test my model object in a way that will allow me to use a mock instance of UserDefaults, but am having trouble with the syntax. I tried adding a userDefaults var, and referring to the var in the @AppStorage class ModelObject { static let shared = ModelObject() let userDefaults: UserDefaults init(userDefaults: UserDefaults = .standard) { self.userDefaults = userDefaults } @AppStorage("enhanced", store: userDefaults) var scriptPickers: Bool = true var defaultDependentValue: String { scriptPickers ? "Enhanced" : "NOT enhanced" } } However I can't find a way to avoid the syntax error this generates: Cannot use instance member 'userDefaults' within property initializer; property initializers run before 'self' is available Any guidance on how I might be able to: continue using @AppStorage be able to test my class in a way that doesn't force me to use UserDefaults.standard thanks, in advance, Mike

Help me! Thanks!

Can I use Apple's sound recognition in my augmented reality app to trigger content ? Or is there another source I can use?

Posting this on behalf of my colleague, who has a project in mind that requires a huge amount of RAM. Is it true that modern Mac Pro's can only have up to 192GB of RAM which is about 8 times less than 5 years old intel based Mac Pros?
