Question: I'm encountering an issue with in-app purchases (IAP) in Unity, specifically for a non-consumable product in the iOS sandbox environment. Below are the details: Environment: Unity Version: 2022.3.55f1 Unity In-App Purchasing Version: v4.12.2 Device: iPhone (15, iOS 18.1.1) Connection: Wi-Fi iOS Settings: In-App Purchases set to “Allowed” initially Problem Behavior: I attempted to purchase a non-consumable item for the first time. The payment is successfully completed by entering the password. I then background the game app and navigate to the iOS Settings to set In-App Purchases to "Don't Allow." After returning to the game and either closing or killing the app, I try to purchase the same non-consumable item again. I checked canMakePayments() through the Apple configuration, and the app correctly detected that I could not make purchases due to the restriction. I then navigate back to Settings and set In-App Purchases to "Allow." Upon returning to the game, I try purchasing the non-consumable item again. A pop-up appears, saying, "You’ve already purchased this. Would you like to get it again for free?" The issue is: Will it deduct money for the second time, and why is the system allowing the user to purchase the same non-consumable item multiple times after purchasing it once? Is this the expected behavior for Unity In-App Purchasing, or is there something I might be missing in handling non-consumable purchases in this scenario? Additional Information: I’ve confirmed that the "In-App Purchases" are set to “Allowed” before attempting the purchase again. I understand that non-consumable products should not be purchased more than once, so I’m unsure why the system is offering to let the user purchase it again. I appreciate any insights into whether this is expected behavior or if I need to adjust how I handle the purchase flow.

The flushContextInternal function in glr_sync.mm:262 called abort internally. What caused this? Was it due to high device temperature or some other reason?

So if I drag an entity in RealityView I have to disable the PhysicsBodyComponent to make sure nothing fights dragging the entity around. This makes sense. When I finish a drag, this closure gets executed: .gesture( DragGesture() .targetedToAnyEntity() .onChanged { e in // ... } .onEnded { e in let velocity: CGSize = e.gestureValue.velocity } If I now re-add PhysicsBodyComponent to the component I just dragged, and I make it mode: .dynamic it will loose all velocity and drop straight down through gravity. Instead the solution is to apply mode: .kinematic and also apply a PhysicsMotionComponent component to the entity. This should retain velocity after letting go of the object. However, I need to instatiate it with PhysicsMotionComponent(linearVelocity: SIMD3<Float>, angularVelocity: SIMD3<Float>). How can I calculate the linearVelocity and angularVelocity when the e.gestureValue.velocity I get is just a CGSize? Is there another prop of gestureValue I should be looking at?

Hi, wanted to test if possible to use Mesa3D OGLon12+D3DMetal 2b3 to get GL>4.1 support on windows apps via D3D12Metal.. using simple wglgears.c app (similar glxgears) and running like: GALLIUM_DRIVER=d3d12 wine64 wglgears64 -info with overridden opengl32.dll using contents from: https://github.com/pal1000/mesa-dist-win/releases/download/24.3.0-rc1/mesa3d-24.3.0-rc1-release-msvc.7z I get: [D3DMetal:LOG:5E53] Unsupported API: CreateCommandQueue1 caused by: https://gitlab.freedesktop.org/mesa/mesa/-/commit/c022c9603d500b59ff5e6f93c8a214d1785ab20a API: https://learn.microsoft.com/en-us/windows/win32/api/d3d12/nf-d3d12-id3d12device9-createcommandqueue1 note setup is correct as using: GALLIUM_DRIVER=llvmpipe wine64 wglgears64 -info I get: GL_RENDERER = llvmpipe (LLVM 19.1.3, 128 bits) GL_VERSION = 4.5 (Compatibility Profile) Mesa 24.3.0-rc1 (git-85ba713d76) GL_VENDOR = Mesa GL_EXTENSIONS = GL_ARB_multisample GL_EXT_abgr GL_EXT_bgra GL_EXT_blend_color GL_EXT_blend_minmax GL_EXT_blend_subtract r GL_EXT_texture.. etc..

Hi there, I'm wondering if it's possible under iOS 28 developer beta to enable MetalFX scaling info with '{"MTL_HUD_ENABLED": "1" for my App. This information has been added to Mac, but looks to be absent on iPhone / iPad

I want to compare the colors of two model entities (spheres). How can i do it? The method i'm currently trying to apply is as follows case let .color(controlColor) = controlMaterial.baseColor, controlColor == .green { // Flip target sphere colour if let targetMaterial = targetsphere.model?.materials.first as? SimpleMaterial, case let .color(targetColor) = targetMaterial.baseColor, targetColor == .blue { targetsphere.model?.materials = [SimpleMaterial(color: .green, isMetallic: false)] // Change to |1⟩ } else { targetsphere.model?.materials = [SimpleMaterial(color: .blue, isMetallic: false)] // Change to |0⟩ } } This method (baseColor) was deprecated in swift 15.0 changes to 'color' but i cannot compare the value color to each other.👾

Added achievements to my approved app. Added them for the next release version, which I am running in simulator. When I look at the Achievements page, I can see that there are 17 Achievements available (correct), but they all show as hidden, despite checking the "No" box in App Store Connect.

Hey all! I'm got my hands on a refurbished mac mini m1 and already diving into metal. At the moment, i'm currently studying graphics programming with opengl and got to a point where I can almost create a 3d cube. However, I noticed there aren't many tutorials for metal cpp but rather demos. One thing I love about graphic programming, is skinning/skeletal animation. At the moment, I can't find any sources or tutorials on how to load skeletal animations into metal-cpp. So, if I create my character in blender and had all types of animations all loaded into a .FBX or maybe .DAE and load this into metal api with metal-cpp, how can I go on about how this works?

Due to the release of ProMotion devices, the system may switch frame rates in certain scenarios, resulting in the loss of reference value for data collected through CADisplayLink callbacks at a fixed 60Hz frame rate. We cannot distinguish whether the slow callback of CADisplayLink is due to a stutter or a system switch in frame rate. I know Hitch Time Ratio, but I can't use this scheme for some reasons. How can I distinguish between stuck and frame rate gear shift in CADisplaylink callback? In iOS 15, CADisplayLink.preferredFrameRateRange.preferred always returns 0, while minimum and maximum do change. Can I use these minimum and maximum range values as criteria to distinguish between frame rate switching and stuttering?

Just found out this key available for visionOS https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.low-latency-streaming It seems to keep video streaming from being interrupted by AWDL, our community needs it badly for self-hosted game streaming (PC to iPhone / iPad). Related apps: Moonlight / VoidLink / SteamLink. Can we expect this on iOS/iPadOS 26, or even iOS/iPadOS 18 ?

as in the environments we have real tiem reflections of movies on a screen or reflections of the surrounding hood in the background... could i get a metallic surface getting accurate reflections of a box on top ? i don't mean getting a rpobe or hdr cubemap, i mean the same accurate reflections as the water of the mt hood with movie i'm wacthing in other app

The title is self-exploratory. I wasn't able to find the CAMetalDisplayLink on the most recent metal-cpp release (metal-cpp_macOS15_iOS18-beta). Are there any plans to include it in the next release?

Hello ladies and gentlemen, I'm writing a simple renderer on the main actor using Metal and Swift 6. I am at the stage now where I want to create a render pipeline state using asynchronous API: @MainActor class Renderer { let opaqueMeshRPS: MTLRenderPipelineState init(/*...*/) async throws { let descriptor = MTLRenderPipelineDescriptor() // ... opaqueMeshRPS = try await device.makeRenderPipelineState(descriptor: descriptor) } } I get a compilation error if try to use the asynchronous version of the makeRenderPipelineState method: Non-sendable type 'any MTLRenderPipelineState' returned by implicitly asynchronous call to nonisolated function cannot cross actor boundary Which is understandable, since MTLRenderPipelineState is not Sendable. But it looks like no matter where or how I try to access this method, I just can't do it - you have this API, but you can't use it, you can only use the synchronous versions. Am I missing something or is Metal just not usable with Swift 6 right now?

Our application is trying to read all resolutions of an external monitor. We have observed that, for the external monitor there is a mismatch in resolution list in our application and the resolution list in system settings. We are using the apple API "CGDisplayCopyAllDisplayModes" to read the resolutions.

Hi everyone I'm experiencing an issue with iPadOS 26 regarding multi-touch gesture detection. When performing a quick four-finger gesture (tap and swipe), the system often fails to recognize the input. This especially affects multi-touch gestures, such as rhythm games with difficult levels. Steps to Reproduce: Place four fingers on the screen. Perform a quick tap or a quick horizontal swipe (like the one used to switch apps). Observe whether the gesture is ignored or detected inconsistently. Expected Behavior: 4-finger multitouch gestures should be recognized regardless of gesture speed, just like previous iPadOS versions. Actual Behavior: Gestures fail to be detected when executed quickly—same gestures still work, and miss notes in rhythm games.

I play this game called Sonic Forces: Speed Battle that's available in the app store and I completed a quest outside of the app on this site called TapResearch for some rewards as I've done before and has worked, but after this one time I can no longer enter back into the game without crashing immediately. I tried deleting and reinstalling but nothing. I even tried signing into a different account but that didn't work either. So then I tried to make a new game center account to try and see if it works, and it did, though all my progress has been restarted. Does anyone know how to fix this?

I am currently using RealityKit (perspective camera) to render a character in my swiftUI app. The character has customization such as clothing items and hair and all objects are properly weighted to the rig. The way the model is setup in Blender is like so: Groups of objects that will be swapped (ex: Shoes -> Shoes objects) and an armature. I then export it to usdc with all objects active. This is the resulting entity hierarchy, viewed in Reality Composer Pro: My problem is that when I export with the Armature Modifier applied to the objects, so that animations get exported, the ModelComponent gets flattened to the armature and swapping entities is no longer as simple as removing the entity with the corresponding name. What's the best practice here? Should animation be exported separately and then applied to the skeleton? If so, how is that achieved? I'm not really sure how to proceed here.

I am currently using RealityKit (perspective camera) to render a character in my swiftUI app. The character has customization such as clothing items and hair and all objects are properly weighted to the rig. The way the model is setup in Blender is like so: Groups of objects that will be swapped (ex: Shoes -> Shoes objects) and an armature. I then export it to usdc with all objects active. This is the resulting hierarchy: Before exporting for the animation (armature modifier applied), I simply had to store the Model entities and swap them in but now when I export with the Armature Modifier applied, so that animations get exported, the ModelComponent gets flattened to the armature and swapping entities and applying new materials to them is no longer as simple. Here's a demo blend file and usdc export with a setup like mine, having an animated bone to swing a cube and sphere, to be swapped so that only one is visible https://www.dropbox.com/scl/fo/be2q6qcztc83z7c4gj1w0/AMapxWc_ip2KZ8oTOYDUMv8?rlkey=rcdaggcxq06dyen09mw5mqmem&st=bnc0d7j0&dl=0 This is how I'm loading the entity and removing a part, with the demo files import SwiftUI import RealityKit struct SwapDemoView: View { var body: some View { RealityView { content in let camera = PerspectiveCamera() camera.transform.translation = SIMD3(x: 0, y: 0.1, z: 3) guard let root = try? await Entity(named: "simpleSwapDemo") else { fatalError("simpleSwapDemo.usdc is not present") } print(root) // Get initial hierarchy guard let cube = root.findEntity(named: "Cube") else { fatalError("Entity cube doesn't exist") } cube.removeFromParent() // <-- Cube is still visible after removal print(root) // Get hierarchy to confirm removal of cube let resource = root.availableAnimations[0] root.playAnimation(resource.repeat()) content.add(root) content.add(camera) } .background(.white) } } And this is what the entity hierarchy looks like in RealityKit before cube removal ▿ 'root' : Entity, children: 1 ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ⟐ Transform ▿ 'Armature' : ModelEntity, children: 2 ⟐ SynchronizationComponent ⟐ ModelComponent ⟐ SkeletalPosesComponent ⟐ AnimationLibraryComponent ⟐ Transform ▿ 'Armature' : Entity ⟐ SynchronizationComponent ⟐ Transform ▿ 'Primitives' : Entity, children: 2 ⟐ SynchronizationComponent ⟐ Transform ▿ 'Sphere' : Entity, children: 1 ⟐ SynchronizationComponent ⟐ Transform ▿ 'Sphere' : Entity ⟐ SynchronizationComponent ⟐ Transform ▿ 'Cube' : Entity, children: 1 ⟐ SynchronizationComponent ⟐ Transform ▿ 'Cube' : Entity ⟐ SynchronizationComponent ⟐ Transform And here's the hierarchy after removal ▿ 'root' : Entity, children: 1 ⟐ SynchronizationComponent ⟐ AnimationLibraryComponent ⟐ Transform ▿ 'Armature' : ModelEntity, children: 2 ⟐ SynchronizationComponent ⟐ ModelComponent ⟐ SkeletalPosesComponent ⟐ AnimationLibraryComponent ⟐ Transform ▿ 'Armature' : Entity ⟐ SynchronizationComponent ⟐ Transform ▿ 'Primitives' : Entity, children: 1 ⟐ SynchronizationComponent ⟐ Transform ▿ 'Sphere' : Entity, children: 1 ⟐ SynchronizationComponent ⟐ Transform ▿ 'Sphere' : Entity ⟐ SynchronizationComponent ⟐ Transform And this is the result: What's the best practice here?

I want to use reality to create a custom material that can use my own shader and support Mesh instancing (for rendering 3D Gaussian splating), but I found that CustomMaterial does not support VisionOS. Is there any other interface that can achieve my needs? Where can I find examples?
