Hello ! We are working on a real-time 2-player online game targeting multiple Apple devices. The following issue only occurs on tvOS: When selecting matchmaking to connect with another random player, the native Game Center interface opens and begins the matchmaking process. Almost immediately after clicking "start", the following log appears in the console, and the matchmaking screen remains indefinitely without completing: Timeout while starting matching with request: <GKMatchRequestInternal 0x30d62f690> { defaultNumberOfPlayers : 0 isLateJoin : 0 localPlayerID : U:bea182d69b85f0839e3958742fbc4609 matchType : 0 maxPlayers : 2 minPlayers : 2 playerAttributes : 4294967295 playerGroup : 1 preloadedMatch : 0 recipientPlayerIDs : <__NSArrayM 0x3034ed5c0> {} recipients : <__NSArrayM 0x3034ee280> {} restrictToAutomatch : 0 version : 1 archivedSharePlayInviteeTokensFromProgrammaticInvite, inviteMessage, localizableInviteMessage, messagesBasedRecipients, properties, queueName, recipientProperties, rid, sessionToken : (null) } . Error: (null) However, as shown in the code snippet below, the task does not complete when the log appears. But when we manually cancel the matchmaking process, the "User cancel" log is correctly triggered. var gkMatchRequest = GKMatchRequest.Init(); gkMatchRequest.MinPlayers = 2; gkMatchRequest.MaxPlayers = 2; var matchRequestTask = GKMatchmakerViewController.Request(gkMatchRequest); matchRequestTask.ContinueWith(t => { Debug.LogException(t.Exception); }, TaskContinuationOptions.OnlyOnFaulted); matchRequestTask.ContinueWith(t => { Debug.Log("User cancel"); }, TaskContinuationOptions.OnlyOnCanceled); matchRequestTask.ContinueWith(t => { Debug.Log("Success"); }, TaskContinuationOptions.OnlyOnRanToCompletion); We have tested this on multiple Apple TV and network types (Wi-Fi, 5G, Ethernet), but we consistently encounter this bug along with the same log message. Could you please help us understand or resolve this issue? Thank you.

I have a CoreImage pipeline and one of my steps is to rotate my image about the origin (bottom left corner) and then translate it. I'm not seeing the behaviour I'm expecting, and I think my problem is in how I'm combining these two steps. As an example, I start with an identity transform (lldb) po transform333 ▿ CGAffineTransform - a : 1.0 - b : 0.0 - c : 0.0 - d : 1.0 - tx : 0.0 - ty : 0.0 I then rotate 1.57 radians (approx. 90 degrees, CCW) transform333 = transform333.rotated(by: 1.57) - a : 0.0007963267107332633 - b : 0.9999996829318346 - c : -0.9999996829318346 - d : 0.0007963267107332633 - tx : 0.0 - ty : 0.0 I understand the current contents of the transform. But then I translate by 10, 10: (lldb) po transform333.translatedBy(x: 10, y: 10) - a : 0.0007963267107332633 - b : 0.9999996829318346 - c : -0.9999996829318346 - d : 0.0007963267107332633 - tx : -9.992033562211013 - ty : 10.007960096425679 I was expecting tx and ty to be 10 and 10. I have noticed that when I reverse the order of these operations, the transform contents look correct. So I'll most likely just perform the steps in what feels to me like the incorrect order. Is anyone willing/able to point me to an explanation of why the steps I'm performing are giving me these results? thanks, mike

Hello, I'm writing an EntityAction that animates a material base tint between two different colours. However, the colour that is being actually set differs in RGB values from that requested. For example, trying to set an end target of R0.5, G0.5, B0.5, results in a value of R0.735357, G0.735357, B0.735357. I can also see during the animation cycle that intermediate actual tint values are also incorrect, versus those being set. My understanding is the the values of material base colour are passed as a SIMD4. Therefore I have a couple of helper extensions to convert a UIColor into this format and mix between two colours. Note however, I don't think the issue is with this functions - even if their outputs are wrong, the final value of the base tint doesn't match the value being set. I wondered if this was a colour space issue? import simd import RealityKit import UIKit typealias Float4 = SIMD4<Float> extension Float4 { func mixedWith(_ value: Float4, by mix: Float) -> Float4 { Float4( simd_mix(x, value.x, mix), simd_mix(y, value.y, mix), simd_mix(z, value.z, mix), simd_mix(w, value.w, mix) ) } } extension UIColor { var float4: Float4 { var r: CGFloat = 0.0 var g: CGFloat = 0.0 var b: CGFloat = 0.0 var a: CGFloat = 0.0 getRed(&r, green: &g, blue: &b, alpha: &a) return Float4(Float(r), Float(g), Float(b), Float(a)) } } struct ColourAction: EntityAction { let startColour: SIMD4<Float> let targetColour: SIMD4<Float> var animatedValueType: (any AnimatableData.Type)? { SIMD4<Float>.self } init(startColour: UIColor, targetColour: UIColor) { self.startColour = startColour.float4 self.targetColour = targetColour.float4 } static func registerEntityAction() { ColourAction.subscribe(to: .updated) { event in guard let animationState = event.animationState else { return } let interpolatedColour = event.action.startColour.mixedWith(event.action.targetColour, by: Float(animationState.normalizedTime)) animationState.storeAnimatedValue(interpolatedColour) } } } extension Entity { func updateColour(from currentColour: UIColor, to targetColour: UIColor, duration: Double, endAction: @escaping (Entity) -> Void = { _ in }) { let colourAction = ColourAction(startColour: currentColour, targetColour: targetColour, endedAction: endAction) if let colourAnimation = try? AnimationResource.makeActionAnimation(for: colourAction, duration: duration, bindTarget: .material(0).baseColorTint) { playAnimation(colourAnimation) } } } The EntityAction can only be applied to an entity with a ModelComponent (because of the material), so it can be called like so: guard let modelComponent = entity.components[ModelComponent.self], let material = modelComponent.materials.first as? PhysicallyBasedMaterial else { return } let currentColour = material.baseColor.tint let targetColour = UIColor(_colorLiteralRed: 0.5, green: 0.5, blue: 0.5, alpha: 1.0) entity.updateColour(from:currentColour, to: targetColour, duration: 2)

I want to display the refresh rate on the screen of the iPhone (14 Pro Max), but each app of the App Store's "Floating Clock", "Floating Clock Premium" and "Screen Renewal Rate - RefreshRate Realtime" can only display two of 60Hz and 120Hz, and I wonder if it can display numbers of 1Hz, 10Hz, tens of Hz, or more than 3 levels. Does anyone know how to do it?

I'm trying to apply a CIBumpDistortion Core Image filter to a view that contains a UILabel (my storyLabel). The goal is to create a visual bump/magnifying glass effect over the text. However, despite my attempts, the filter doesn't seem to render at all. The view and the label appear as normal, with no distortion effect. I've tried adjusting the filter parameters and reviewing the view hierarchy, but without success. I also haven't been able to find clear documentation or examples for applying this filter to a UIView's layer. // // TVView.swift // Mistery // // Created by Joje on 31/07/25. // import CoreImage import CoreImage.CIFilterBuiltins import UIKit import AVFoundation final class TVView: UIView { // propriedades animacao texto private var textAnimationTimer: Timer?

Hello, We are experiencing an issue with apparent lag or latency when interacting with objects in Unity using the XR Interaction Toolkit. Even when interactables are configured with the Movement Type set to Instantaneous, objects exhibit a noticeable delay when following hand movement. This issue is particularly apparent when the hand moves at higher speeds. We would like to know: is any additional configuration required, or is there something else we need to do to resolve this? Thank you very much for your assistance.

I haven't been looking at screensavers for a long time because of Apple's lack of will (or resources?) to provide a public version of the private modern SDK used by Apple for a very long time now. I'm now looking at the Screen Saver pane in System Settings (the What-If version of System Preferences in an alternate universe where all screens are in portrait mode). In macOS Sequoia, it seems like 3rd party screensavers are not welcome considering that they are relegated to the "Other" section at the bottom of the list and you have to click Show All to start seeing 3rd party screen savers. I also had a quick look at macOS Tahoe Beta 3 and it looks like that all the real screensavers are gone (3rd party and the ones from Apple: Hello, Message, Flurry, etc.) or at least it requires to be a Nobel Prize to find them (and the Search field is not useful). I tried to install a 3rd party screen saver on macOS Tahoe Beta 3, it doesn't show up in the list. To summarize: No public access to modern APIs AFAIK. UI that is hostile to 3rd party screen savers on macOS Sequoia. Apparently only screensavers that are slideshows or movies curated by Apple in macOS Tahoe b3. Hence the question: Is there any future for screen savers on macOS? Because if there's none, I won't waste my time trying to update some old screen savers.

Hi! I'm having issues retrieving the intrinsics matrix of camera poses for photogrammetry sessions. The camera object always seems to be nil, no matter what dataset I use. From the documentation, I can't see any indication of this issue, is there something I need to do on the code side? Or it's something related to the photo dataset? I'm on MacOS 15.2

I am suspecting that setting GCController.shouldMonitorBackgroundEvents = true does not actually make the game controllers inputs accessible to the app when it is in the background. About this value the official documentation says: A Boolean value that indicates whether the app needs to respond to controller events when it isn’t the frontmost app. Now the behavior is that when the app is in focus the users inputs do get correctly recognized but as soon as the app enters the background no inputs get recognized. The controller does not get reported as disconnecting and still works for example in launchpad. I am sure that about 2 months ago when I first used this it did work as one would expect. I also have seen that an app which lets users execute certain actions using their controller has stoped working recently, adding to my suspicion of the feature being broken. Here is a minimum reproducible example: import SwiftUI import GameController @main struct TestingControllerConnectionApp: App { @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate var body: some Scene { WindowGroup { ContentView() } } } class AppDelegate: NSObject, NSApplicationDelegate { var statusItem: NSStatusItem? var controller: GCController? func applicationDidFinishLaunching(_ notification: Notification) { setupMenuBar() GCController.shouldMonitorBackgroundEvents = true NotificationCenter.default.addObserver( self, selector: #selector(controllerDidConnect), name: .GCControllerDidConnect, object: nil ) NotificationCenter.default.addObserver( self, selector: #selector(controllerDidDisconnect), name: .GCControllerDidDisconnect, object: nil ) } @objc private func setupMenuBar() { let menu = NSMenu() menu.addItem(NSMenuItem(title: "Quit", action: #selector(quitApp), keyEquivalent: "q")) statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength) statusItem?.button?.image = NSImage(resource: .controllerBar) statusItem?.menu = menu } @objc private func quitApp() { NSApp.terminate(nil) } @objc private func controllerDidConnect(_ notification: Notification) { if let controller = notification.object as? GCController { print("Controller connected") self.controller = controller if let gamepad = controller.extendedGamepad { gamepad.buttonA.pressedChangedHandler = { _, _, pressed in print("Button A pressed: \(pressed)") } } } } @objc private func controllerDidDisconnect(_ notification: Notification) { print("Controller disconnected") } } This is created in a completely fresh Xcode project and NSHumanInterfaceDeviceUsageDescription has been added. I am using a PS5 Controller and a Mac running MacOS 15.4.1 which has been restarted and only Xcode and the app have been opened. I have tested this with setting a multitude of different entitlements and capabilities including: NSHumanInterfaceDeviceUsageDescription Supports Controller User Interaction Required background modes -> App communicates with an accessory com.apple.security.device.bluetooth com.apple.security.device.hid com.apple.security.device.usb I have also set this value at different points in the code with no change of effect. Does anybody see if there is any fault in my code or my understanding of the effect of the value 'shouldMonitorBackgroundEvents'? Or is this the functionality actually being broken on Apples part?

Hi, I am trying to detect if all the screen are in fullscreen mode. The current approach is to get all windows' information from CGWindowListCopyWindowInfo and then compare the frame and coordinate with the frame of NSScreen.screens. However, there is a problem, the y position of the window seems to be relative to the screen. As it is not absolute position, I cannot compare it with the coordinate of the screen. Does anyone know if there are other information that I can use? Or is there a way to retrieve the absolute position or screen ID from the GCWIndow object?

I’m trying to play an Apple Immersive video in the .aivu format using VideoPlayerComponent using the official documentation found here: https://developer.apple.com/documentation/RealityKit/VideoPlayerComponent Here is a simplified version of the code I'm running in another application: import SwiftUI import RealityKit import AVFoundation struct ImmersiveView: View { var body: some View { RealityView { content in let player = AVPlayer(url: Bundle.main.url(forResource: "Apple_Immersive_Video_Beach", withExtension: "aivu")!) let videoEntity = Entity() var videoPlayerComponent = VideoPlayerComponent(avPlayer: player) videoPlayerComponent.desiredImmersiveViewingMode = .full videoPlayerComponent.desiredViewingMode = .stereo player.play() videoEntity.components.set(videoPlayerComponent) content.add(videoEntity) } } } Full code is here: https://github.com/tomkrikorian/AIVU-VideoPlayerComponentIssueSample But the video does not play in my project even though the file is correct (It can be played in Apple Immersive Video Utility) and I’m getting this error when the app crashes: App VideoPlayer+Component Caption: onComponentDidUpdate Media Type is invalid Domain=SpatialAudioServicesErrorDomain Code=2020631397 "xpc error" UserInfo={NSLocalizedDescription=xpc error} CA_UISoundClient.cpp:436 Got error -4 attempting to SetIntendedSpatialAudioExperience [0x101257490|InputElement #0|Initialize] Number of channels = 0 in AudioChannelLayout does not match number of channels = 2 in stream format. Video I’m using is the official sample that can be found here but tried several different files shot from my clients and the same error are displayed so the issue is definitely not the files but on the RealityKit side of things: https://developer.apple.com/documentation/immersivemediasupport/authoring-apple-immersive-video Steps to reproduce the issue: - Open AIVUPlayerSample project and run. Look at the logs. All code can be found in ImmersiveView.swift Sample file is included in the project Expected results: If I followed the documentation and samples provided, I should see my video played in full immersive mode inside my ImmersiveSpace. Am i doing something wrong in the code? I'm basically following the documentation here. Feedback ticket: FB19971306

When importing FBX animations (generated by Cinema 4d or Blender) the models come in very far way and cannot resize or zoomed in. I have tried every setting from both programs to no avail. Is there a secret to providing the right export options? When importing without animations/and rigging the model imports fine and correct size. But once motion is included, something is awry. I also tried changing base units in Converter, but did not work. I have attache my model heirarchy in C4D as well as the imported result. It appears the animation is imported, as I can see it move, but can barely see it :)

I have a scene built up in RealityComposerPro, in which I've added a ParticleEmitter with isEmitting set to False and 'Loop' set to True. In my app, when I toggle isEmitting to True there can be a delay of a few seconds before the ParticleEmitter starts. However, if I programatically add the emitter in code at that point, it starts immediately. To be clear, I'm seeing this on the VisionOS simulator - I don't have access to a device at this time. Am I misunderstanding how to control the ParticleEmitter when I need precise control on when it starts.

Hello, we are working on a iOS game project, as progress, the project grows larger and larger. Because we are using other game dependencies and libraries, here larger and larger refers to the whole project, and our source files integrated and compiled by Xcode are not many. Now, it seems we hit a bottleneck, when I add new files or functions to the previous files to implement a new feature, Xcode compile stucks(stops), it's Indexing | Initializing datastore forever, cannot produce a final build. macOS 15.1, Xcode 16.2 Can you provide any solutions to solve this problem?

I am working on a custom resolve tile shader for a client. I see a big difference in performance depending on where we write to: 1- the resolve texture of the color attachment 2- a rw tile shader texture set via [renderEncoder setTileTexture: myResolvedTexture] Option 2 is more than twice as slow than option 1. Our compute shader writes to 4 UAVs so just using the resolve texture entry is not possible. Why such a difference as there is no more data being written? Can option 2 be as fast as option 1? I can demonstrate the issue in a modified version of the Multisample code sample.

There is a sample project from Apple here. It has a scene of a city at night and you can move in it. It basically has 2 parts: application code written in what looks like Objective-C (I am more familiar with C++), which inherits from things like NSObject, MTKView, NSViewController and so on - it processes input and all app-related and window-related stuff. rendering code that also looks like Objective-C. Btw both parts are mostly in .mm files (Obj-C++ AFAIK). The application part directly uses only one class from the rendering part - AAPLRenderer. I want to move the rendering part to C++ using metal-cpp. For that I need to link metal-cpp to the project. I did it successfully with blank projects several times before using this tutorial. But with this sample project Xcode can't find Foundation/Foundation.hpp (and other metal-cpp headers). The error says this: Did not find header 'Foundation.hpp' in framework 'Foundation' (loaded from '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.0.sdk/System/Library/Frameworks') Pls help

In swipe-driven games, a first downward swipe starting near the home indicator can trigger Reachability, even when using preferredScreenEdgesDeferringSystemGestures = .bottom and prefersHomeIndicatorAutoHidden = true. This causes the app to slide down to half screen and breaks gameplay. Please consider an API to temporarily defer Reachability while a custom gesture is active (similar to existing system gesture deferral), without disabling accessibility globally. Environment: Devices: iPhones with Home Indicator (Face ID) Why this matters: Bottom-origin swipes are core in many games (flick shots, slingshot, physics toss, bottom sheets). Current workarounds degrade UX and discoverability, and players still accidentally trigger Reachability. Feedback Assistant Post

I am making a framework in C++ using metal-cpp, basically a small game engine. I am also consequently using metal-cpp-extensions provided in LearnMetalCPP to make applications work. For one of my classes, I needed to add AppKit.hpp inside a public header file, so I moved it and its associate headers(NSApplication.hpp, NSMenu.hpp, etc.) from Project headers to Public in Build Phases' Headers, however, it started giving me the error "cast of C pointer type 'void *' to Objective-C pointer type 'Class' requires a bridged cast" at several points in the AppKit headers. They don't appear when AppKit and its associates are in the Project headers, or when they are in the Private headers and no headers import it. I imagined that disabling Objective-C ARC and Using __bridge casts outside of ARC in Build Settings would solve it, but it didn't budge. I imagined it wouldn't involve actively changing the headers would be the answer, but even if I try to put __bridge before the problematic casts, it didn't recognize __bridge. How do I solve this? And why is it only happening in Public and not Project headers?
