I work on a team that provides an SDK for another game to handle various tasks like authentication. They are experiencing a case where devices using iOS 17 are failing to authenticate with GameCenter, receiving the message "The requested operation could not be completed because local player has not been authenticated." We imagine this is because they still have some setup to finish regarding GameCenter itself, and we're working with them to take care of that. However, on iOS 18, their app ends up waiting indefinitely for GameCenter authentication messages that it never receives. That's where we're puzzled. We expect them to have the same outcome regardless of OS version. We initiate GameCenter authentication by setting an authenticateHandler after some initial application setup. The handler has code to account for UI, errors, and successful authentication. On iOS 17, it's clear that it's getting called as expected because they receive an indication that the player isn't authenticated. But on iOS 18, it looks like the same handler code on iOS 18 isn't being called at all. Are there differences in how iOS 18 interacts with the authenticationHandler that we somehow aren't accounting for? Or is there potentially something else that we're doing incorrectly that is manifesting only on iOS 18? Here's a simplified version of our login function code (in Obj-C++). There is no OS-specific code, and the job that owns this function does stay in scope until after authentication is complete. void beginLogin() { // Snip: Check if the user is already logged in. // Snip: Prevent multiple concurrent calls to this function. auto authenticateHandler = ^(UIViewController* gcViewController, NSError* error) { if (gcViewController != nil) { // Snip: Display the UI } else if (error != nil) { // Snip: Handle the error. } else { if ([[GKLocalPlayer localPlayer] isAuthenticated]) { // Snip: Handle successful authentication. } else { // Snip: Handle other case. } } }; [[GKLocalPlayer localPlayer] setAuthenticateHandler: authenticateHandler]; }

I've tried out a ParticleEmitter in Reality Composer Pro to produce a burst of particles that don't move (i.e. speed close to zero). When viewing from different angles, it clearly looks like the particles are rendered exactly in the wrong order, that is, front first and back last. In other words, back particles obscure front particles. I would prefer it the correct way around. I've only tried this interactively in Reality Composer Pro, not programmatically, but I assume I would get the same result. My Reality Composer Pro "File" (zipped): https://gert-rieger-edv.de/Posts/Post-1/RealityParticles.zip Screenshot: Click on the ParticleEmitter object, then on its Play button, then select the Particles tab and click on "Burst" a few times to get a few random particles.

I was wondering if there's a method on MacOS to have my application hide a hid device such as a game controller and instead have the receiving game/application see my app's virtual controller? Is this possible via DriverKit or some other form of kernel level coding? On Windows we have a tool known as HidHide that hids a game controller from all other applications. Is it possible to implement such behavior into an app or is that system level?

We are developing a hybrid iOS app where Angular content is rendered inside a WKWebView, hosted by a native Swift application. We use the GameController framework to detect whether an external Bluetooth keyboard is connected to an iPad. The following code is executed when the app enters the foreground and also when requested by the web layer: func keyboardStatusHandler(){ let isKeyboardConnected = GCKeyboard.coalesced != nil if(!isKeyboardConnected){ //sent status to Angular } else { //sent status to Angular } } Crash details We are seeing intermittent crashes on iPad with the following stack trace: Crashed: GCDeviceSession.HID 0 libobjc.A.dylib 0x7db8 objc_retain_x8 + 16 1 libsystem_blocks.dylib 0xfb8 void HelperBase<ExtendedInline>::copyCapture<(HelperBase<ExtendedInline>::BlockCaptureKind)3>(unsigned int) + 48 2 libsystem_blocks.dylib 0xbc4 HelperBase<GenericInline>::copyBlock(Block_layout*, Block_layout*) + 108 3 libsystem_blocks.dylib 0xc94 _call_copy_helpers_excp + 60 4 libsystem_blocks.dylib 0xef8 _Block_copy + 412 5 libdispatch.dylib 0x1a70 _dispatch_Block_copy + 32 6 libdispatch.dylib 0x792c dispatch_async + 56 7 libdispatch.dylib 0x792c dispatch_channel_async + 56 8 GameController 0xea6dc -[GCKeyboardInput _handleKeyboardEvent:] + 324 9 GameController 0x22508 __53-[_GCKeyboardEventHIDAdapter initWithSource:service:]_block_invoke + 376 10 GameController 0x11d30 -[_GCHIDEventSubject publishHIDEvent:] + 268 11 GameController 0xb79cc __40-[_GCHIDEventUIKitClient initWithQueue:]_block_invoke_3 + 44 12 libdispatch.dylib 0x1b584 _dispatch_client_callout + 16 13 libdispatch.dylib 0x12088 _dispatch_async_and_wait_invoke_and_complete_recurse + 272 14 libdispatch.dylib 0x8448 _dispatch_async_and_wait_f + 108 15 GameController 0xb7984 __40-[_GCHIDEventUIKitClient initWithQueue:]_block_invoke_2 + 132 16 GameController 0xb746c __48-[__GCHIDEventUIKitClient _initWithApplication:]_block_invoke + 256 17 UIKitCore 0x11fd394 __61-[UIEventFetcher _setHIDGameControllerEventObserver:onQueue:]_block_invoke_3 + 40 18 libdispatch.dylib 0x1aac _dispatch_call_block_and_release + 32 19 libdispatch.dylib 0x1b584 _dispatch_client_callout + 16 20 libdispatch.dylib 0xa2d0 _dispatch_lane_serial_drain + 740 21 libdispatch.dylib 0xadac _dispatch_lane_invoke + 388 22 libdispatch.dylib 0x151dc _dispatch_root_queue_drain_deferred_wlh + 292 23 libdispatch.dylib 0x14a60 _dispatch_workloop_worker_thread + 540 24 libsystem_pthread.dylib 0xa0c _pthread_wqthread + 292 25 libsystem_pthread.dylib 0xaac start_wqthread + 8 Observed scenarios Crash occurs when the app transitions from background to foreground Crash also occurs when the Angular layer requests keyboard status, triggering the same code path Questions Has anyone encountered crashes related to GCKeyboard.coalesced or GCKeyboardInput like this?

Is there a recommended or safer way to detect external keyboard connection status on iPad (especially when using WKWebView)?

I am trying to implement a ChacterControllerComponent using the following URL. https://developer.apple.com/documentation/realitykit/charactercontrollercomponent I have written sample code, but PhysicsSimulationEvents.WillSimulate is not executed and nothing happens. import SwiftUI import RealityKit import RealityKitContent struct ImmersiveView: View { let gravity: SIMD3<Float> = [0, -50, 0] let jumpSpeed: Float = 10 enum PlayerInput { case none, jump } @State private var testCharacter: Entity = Entity() @State private var myPlayerInput = PlayerInput.none var body: some View { RealityView { content in // Add the initial RealityKit content if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) testCharacter = immersiveContentEntity.findEntity(named: "Capsule")! testCharacter.components.set(CharacterControllerComponent()) let _ = content.subscribe(to: PhysicsSimulationEvents.WillSimulate.self, on: testCharacter) { event in print("subscribe run") let deltaTime: Float = Float(event.deltaTime) var velocity: SIMD3<Float> = .zero var isOnGround: Bool = false // RealityKit automatically adds `CharacterControllerStateComponent` after moving the character for the first time. if let ccState = testCharacter.components[CharacterControllerStateComponent.self] { velocity = ccState.velocity isOnGround = ccState.isOnGround } if !isOnGround { // Gravity is a force, so you need to accumulate it for each frame. velocity += gravity * deltaTime } else if myPlayerInput == .jump { // Set the character's velocity directly to launch it in the air when the player jumps. velocity.y = jumpSpeed } testCharacter.moveCharacter(by: velocity * deltaTime, deltaTime: deltaTime, relativeTo: nil) { event in print("playerEntity collided with \(event.hitEntity.name)") } } } } } } The scene is loaded from RCP. It is simple, just a capsule on a pedestal. Do I need a separate code to run testCharacter from this state?

After updating iPad/iPhone devices from iOS 18 to iOS 26, PhotogrammetrySession intermittently crashes during photogrammetry processing. The same workflow was stable on iOS 18 with no code changes to the app. Environment: OS versions: Works on OS 18, crashes on OS 26 Device: iPad/iPhone (reproducible across devices) Source images: ~170-200 JPG files at 2160 x 3840 resolution Reproduction: The crash occurs consistently on the second or third sequential run of the photogrammetry session with the same image set. First run typically succeeds. Crash details: Xcode shows an uncaught exception during image processing: terminating due to uncaught exception of type std::bad_alloc: std::bad_alloc VTPixelTransferSession 420f sid 269 (2160.00 x 3840.00) [0.00 0.00 2160 3840] rowbytes( 2160, 2160 ) Color( (null), 0x0, (null), (null), ITU_R_601_4 ) => 24 sid 19 (2160.00 x 3840.00) [0.00 0.00 2160 3840] rowbytes( 6528 ) Color( 0x0, (null), (null), (null) ) This appears to be a memory allocation failure in VTPixelTransferSession during color space conversion. Has anyone else experienced similar crashes with CorePhotogrammetry on iOS 26, or found workarounds?

Hey, I've been struggling with this for some days now. I am trying to write to a sparse texture in a compute shader. I'm performing the following steps: Set up a sparse heap and create a texture from it Map the whole area of the sparse texture using updateTextureMapping(..) Overwrite every value with the value "4" in a compute shader Blit the texture to a shared buffer Assert that the values in the buffer are "4". I have a minimal example (which is still pretty long unfortunately). It works perfectly when removing the line heapDesc.type = .sparse. What am I missing? I could not find any information that writes to sparse textures are unsupported.

Hey I'm using the CIDepthBlurEffect Core Image Filter in my app. It seems to work ok but I get these errors in the console when calling the class. CoreImage Metal library does not contain function for name: sparserendering_xhlrb_scan CoreImage Metal library does not contain function for name: sparserendering_xhlrb_diffuse CoreImage Metal library does not contain function for name: sparserendering_xhlrb_copy_back CoreImage Metal library does not contain function for name: plain_or_sRGB_copy Am I missing some sort of import to gain these Metal functions? I am using my own custom shaders but I assume you'd be able to use them along side the built in ones.

We have a macOS app (not yet released, but in use by ourselves), that provides scoreboards for streaming sport events. Today it is expected, that there are nice animations for goals, etc. We are streaming using NDI, which requires a CVPixelBuffer for each frame. We currently create these animations using CABasicAnimation, CAAnimation and CAKeyframeAnimation. In addition we use ScreenCaptureKit to generate the frames. This works fine with 25/30 fps, as long as the window where our animations are performed in is visible. But this is not what it should be. We have a smaller window as main app window and control display performing the animations in reduced size, while the streaming animations need to be in HD format and later maybe in 4K. When using an offscreen window, the animations are not calculated. We get 1 frame per second or so. So we actually have to connect an external display to the MacBook and open the large windows there. Ugly solution. Do we use a completely wrong approach? Or is there a way to tell the macOS to perform the animations although it is an offscreen window? If it cannot work that way, what is an alternative?

Hello, MacOS 26 Betas are limiting games (noticeably, games that use java) to the native display of the MacBook Pro (120hz). Even connecting an external display this is not changing. I have submitted a bug report, but I have not had any responses to it yet. I am looking to see if anyone may have an answer or fix to this issue. Thanks!

I'm using RealityView in my iOS game mxied with SwiftUI. For the following 2 example usages, the simulator will only render the first RealityView, and the second one is either super laggy or show a black model. Running on the real device is all good, just simualtor has this issue. Have a TabView and each tab has a RealityView. Have a root view and detail view connected via a push navigation, both root and detail have a RealityView. In the Simulator, the second RealityView is going to be very choppy and basically unusable, but on a real iPhone everything looks great. Is this a known simulator issue or I did something bad?

Problem Summary After upgrading to iOS 26.1 and 26.2, I'm experiencing a particle positioning bug in RealityKit where ParticleEmitterComponent particles render at an incorrect offset relative to their parent entity. This behavior does not occur on iOS 18.6.2 or earlier versions, suggesting a regression introduced in the newer OS builds. Environment Details Operating System: iOS 26.1 & iOS 26.2 Framework: RealityKit Xcode Version: 16.2 (16C5032a) Expected vs. Actual Behavior Expected: Particles should render at the position of the entity to which the ParticleEmitterComponent is attached, matching the behavior on iOS 18.6.2 and earlier. Actual: Particles appear away from their parent entity, creating a visual misalignment that breaks the intended AR experience. Steps to Reproduce Create or open an AR application with RealityKit that uses particle components Attach a ParticleEmitterComponent to an entity via a custom system Run the application on iOS 26.1 or iOS 26.2 Observe that particles render at an offset position away from the entity Minimal Code Example Here's the setup from my test case: Custom Component & System: struct SparkleComponent4: Component {} class SparkleSystem4: System { static let query = EntityQuery(where: .has(SparkleComponent4.self)) required init(scene: Scene) {} func update(context: SceneUpdateContext) { for entity in context.scene.performQuery(Self.query) { // Only add once if entity.components.has(ParticleEmitterComponent.self) { continue } var newEmitter = ParticleEmitterComponent() newEmitter.mainEmitter.color = .constant(.single(.red)) entity.components.set(newEmitter) } } } AR Setup: let material = SimpleMaterial(color: .gray, roughness: 0.15, isMetallic: true) let model = Entity() model.components.set(ModelComponent(mesh: boxMesh, materials: [material])) model.components.set(SparkleComponent4()) model.position = [0, 0.05, 0] model.name = "MyCube" let anchor = AnchorEntity(.plane(.horizontal, classification: .any, minimumBounds: [0.2, 0.2])) anchor.addChild(model) arView.scene.addAnchor(anchor) Questions for the Community Has anyone else encountered this particle positioning issue after updating to iOS 26.1/26.2? Are there known workarounds or configuration changes to ParticleEmitterComponent that restore correct positioning? Is this a confirmed bug, or could there be a change in coordinate system handling or transform inheritance that I'm missing? Additional Information I've already submitted this issue via Feedback Assistant(FB21346746)

Problem Description I'm encountering an issue with SCNTechnique where the clearColor setting is being ignored when multiple passes share the same depth buffer. The clear color always appears as the scene background, regardless of what value I set. The minimal project for reproducing the issue: https://www.dropbox.com/scl/fi/30mx06xunh75wgl3t4sbd/SCNTechniqueCustomSymbols.zip?rlkey=yuehjtk7xh2pmdbetv2r8t2lx&st=b9uobpkp&dl=0 Problem Details In my SCNTechnique configuration, I have two passes that need to share the same depth buffer for proper occlusion handling: "passes": [ "box1_pass": [ "draw": "DRAW_SCENE", "includeCategoryMask": 1, "colorStates": [ "clear": true, "clearColor": "0 0 0 0" // Expecting transparent black ], "depthStates": [ "clear": true, "enableWrite": true ], "outputs": [ "depth": "box1_depth", "color": "box1_color" ], ], "box2_pass": [ "draw": "DRAW_SCENE", "includeCategoryMask": 2, "colorStates": [ "clear": true, "clearColor": "0 0 0 0" // Also expecting transparent black ], "depthStates": [ "clear": false, "enableWrite": false ], "outputs": [ "depth": "box1_depth", // Sharing the same depth buffer "color": "box2_color", ], ], "final_quad": [ "draw": "DRAW_QUAD", "metalVertexShader": "myVertexShader", "metalFragmentShader": "myFragmentShader", "inputs": [ "box1_color": "box1_color", "box2_color": "box2_color", ], "outputs": [ "color": "COLOR" ] ] ] And the metal shader used to display box1_color and box2_color with splitting: fragment half4 myFragmentShader(VertexOut in [[stage_in]], texture2d<half, access::sample> box1_color [[texture(0)]], texture2d<half, access::sample> box2_color [[texture(1)]]) { half4 color1 = box1_color.sample(s, in.texcoord); half4 color2 = box2_color.sample(s, in.texcoord); if (in.texcoord.x < 0.5) { return color1; } return color2; }; Expected Behavior Both passes should clear their color targets to transparent black (0, 0, 0, 0) The depth buffer should be shared between passes for proper occlusion Actual Behavior Both box1_color and box2_color targets contain the scene background instead of being cleared to transparent (see attached image) This happens even when I explicitly set clearColor: "0 0 0 0" for both passes Setting scene.background.contents = UIColor.clear makes the clearColor work as expected, but I need to keep the scene background for other purposes What I've Tried Setting different clearColor values - all are ignored when sharing depth buffer Using DRAW_NODE instead of DRAW_SCENE - didn't solve the issue Creating a separate pass to capture the background - the background still appears in the other passes Various combinations of clear flags and render orders Environment iOS/macOS, running with "My Mac (Designed for iPad)" Xcode 16.2 Question Is this a known limitation of SceneKit when passes share a depth buffer? Is there a workaround to achieve truly transparent clear colors while maintaining a shared depth buffer for occlusion testing? The core issue seems to be that SceneKit automatically renders the scene background in every DRAW_SCENE pass when a shared depth buffer is detected, overriding any clearColor settings. Any insights or workarounds would be greatly appreciated. Thank you!

Hi all im having a variety of issues with gamekit matchmaking. On the simulator the matchmaking ui pops up and I can click Quick Match, then immediately "Failed to find Players" this is the same with a real Apple ID and a sandbox account. If I use real devices the app at least discovers a match, but then the match none of the delegate methods for the match ever get called and the logs are filled with socket not connected and various errors. My questions are: Should match making via quick match work in the simulator, I have seen tutorial videos etc of this working, but I can't seem to get it to work. How do people debug issues with GameCenter / Gamekit to find out why its not able to connect? Many thanks in advance

How can one match the walls and floor of a given CapturedRoom ? The transform.eulerAngles of a floor z & y are always 0 ! And the polygons seems to have a different orientation than the walls. So how to figure out the rotation and match the one from the walls ?

Hi, I’m testing Unity’s Spaceship HDRP demo on iPhone 17 Pro Max and iPad Pro M4 (iOS 26.1). Everything renders correctly, and my custom MetalFX Spatial plugin initializes successfully — it briefly reports active scaling (e.g. 1434×660 → 2868×1320 at 50% scaling), then reverts to native rendering a few frames later. Setup: Xcode 16.1 (targeting iOS 18) Unity 2022.3.62f3 (HDRP) Metal backend Dynamic Resolution enabled in HDRP assets and cameras Relevant Xcode console excerpt: [MetalFXPlugin] MetalFX_Enable(True) called. [SpaceshipOptions] MetalFX enabled with HDRP dynamic resolution integration. [SpaceshipOptions] Disabled TAA for MetalFX Spatial. [SpaceshipOptions] Created runtime RenderTexture: 1434x660 [MetalFX] Spatial scaler created (1434x660 → 2868x1320). [MetalFX] Processed frame with scaler. [MetalFXPlugin] Sent RenderTexture (1434x660) to MetalFX. Output target 2868x1320. [SpaceshipOptions] MetalFX target set: 1434x660 [SpaceshipOptions] Camera targetTexture cleared after MetalFX handoff. It looks like HDRP clears the camera’s target texture right after MetalFX submits the frame, which causes it to revert to native rendering. Is there a recommended way to persist or rebind the MetalFX output texture when using HDRP on iOS? Unity doesn’t appear to support MetalFX in the Editor either: Thanks!

In the process of using ARKit's image tracking, we found that different images have significant differences in recognizability. How can we judge the quality of this image in ARKit's image tracking for this situation?

The “explore spatial accessory input on visionOS” presentation from WDC25 interests me. I bought both the MUSE Logitech stylus and the PS VR2 sense controllers to try out with the sculpting app presented by the author, engineer Amanda Han. Unfortunately the app itself was not included. Could the app be made available for downloading as well as the Xcode project? I appreciate any assistance the author and your team could provide. Thank you.
