I have an app that uses GameController to read the inputs of a connected JoyCon. However, the controller also interacts with the OS. For example, when I press the Home button on the controller, it brings me to the home of my Vision Pro. Is it possible to disable this interaction while still being able to read the controller inputs inside my app?

在正常游戏中，如果非常频繁的调用assetBundle.Unload接口，会导致游戏应用画面卡死，但是游戏的背景音乐仍然正常播放。这类问题仅发生在iphone16 和iphone17的手机上，低版本的手机没有任何问题，请问该如何解决这个问题？

TLDR; I can't get QueueName to work with matchmaking a turn-based match in Unity using matchmaking rules. Long version: I'm using the apple unity plugin found here: https://github.com/apple/unityplugins/blob/main/plug-ins/Apple.GameKit/Apple.GameKit_Unity/Assets/Apple.GameKit/Documentation~/Apple.GameKit.md I have created a Queue, RuleSet and a simple Rule to match players by following these docs tightly: https://developer.apple.com/documentation/gamekit/finding-players-using-matchmaking-rules. Here is the single rule I have that drives matchmaking: { "data" : { "type" : "gameCenterMatchmakingRules", "id" : "[hiddden-rule-id]", "attributes" : { "referenceName" : "ComplimentaryFactionPreference", "description" : "default desc", "type" : "MATCH", "expression" : "requests[0].properties.preference != requests[1].properties.preference", "weight" : null }, "links" : { "self" : "https://api.appstoreconnect.apple.com/v1/gameCenterMatchmakingRules/[hidden-rule-id]" } }, "links" : { "self" : "https://api.appstoreconnect.apple.com/v1/gameCenterMatchmakingRules" } } which belongs to a rule set which belongs to a queue. I have verified these are setup and linked via the App Store Connect API. Additionally, when I tested queue-based matchmaking without a queue established, I got an error in Unity. Now, with this, I do not. However there is a problem when I attempt to use the queue for matchmaking. I have the basic C# function here: public override void StartSearch(NSMutableDictionary<NSString, NSObject> properties) { if (searching) return; base.StartSearch(properties); //Establish matchmaking requests _matchRequest = GKMatchRequest.Init(); _matchRequest.QueueName = _PreferencesToQueue(GetSerializedPreferences()); _matchRequest.Properties = properties; _matchRequest.MaxPlayers = PLAYERS_COUNT; _matchRequest.MinPlayers = PLAYERS_COUNT; _matchTask = GKTurnBasedMatch.Find(_matchRequest); } The _PreferencesToQueue(GetSerializedPreferences()); returns the exact name of the queue I added my ruleset to. After this function is called, I poll the task generated from the .Find(...) function. Every time I run this function, a new match is created almost instantly. No two players are ever added to the same match. Further, I'm running two built game instances, one on a mac and another on an ipad and when I simultaneously test, I am unable to join games this way. Can someone help me debug why I cannot seem to match make when using a queue based approach?

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.

var allLeaderboards = await GKLeaderboard.LoadLeaderboards(); Log(allLeaderboards.Count); // returns 0 What am I missing?? What doesn’t work: await GKGameActivityDefinition.LoadGameActivityDefinitions() → count = 0 await GKLeaderboard.LoadLeaderboards() (no args) → 0 leaderboards await GKLeaderboard.LoadLeaderboards("MY ID") → returns 0 GkGameActivity.SetScoreOnLeaderboard(Leaderboard, score, context); returns an error since my Leaderboard is null. Activities and leaderboards are defined in GameCenterResources.gamekit in Xcode. Achievements that I add locally in the .gamekit file do not appear at runtime either; only ASC live ones show. ** What works:** xcode- debug- Gamekit- Manage Game progress- I can submit new scores with the plus button and see the notification on my device. await GKLocalPlayer.Authenticate() succeeds. await GKAchievement.LoadAchievements() returns the list of achievements configured in App Store Connect- but not any new local achievements created in Xcode in GameCenterResources.gamekit Environment Device/OS: iPhone on iOS 26.0 beta (Game Center sandbox) Xcode: 26.0 beta 6 Unity: 2022.3.21 Apple GameKit Unity plugin: 2025-beta1 (GameKit package) Signing: Game Center capability enabled; using development provisioning profile GameKit resources: GameCenterResources.gamekit in project (Target: Unity-iPhone), appears under Build Phases → Copy Bundle Resources

This is the first time I have tried adding achievements to my games. The online documentation says: "Before you can access achievements in your code, you can configure them in Xcode and sync the configuration updates you make with App Store Connect. Begin configuring achievements by creating a GameKit configuration file. In Xcode, choose File > New > File from Template. Select GameKit File, and click Next. In the sheet that appears, enter a name for the configuration and click Create." Sounds easy - except Xcode 16.2 does not have a GameKit File as one of the Templates. Please advise on how to proceed and it would be nice if the documentation were updated.

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?

Hi, seems MSL is missing support for a clock() shader instruction available in other graphics APIs like Vulkan or OpenGL for example.. useful for counting cost in number of clock cycles of some code insider shader with much finer granularity than launching a micro kernel with same instructions and measuring cycles cost from CPU.. also useful for MoltenVK to support that extensions.. thanks..

Like many folks here, I've recently attempted to build Apple's Game Porting Toolkit on my machine and ran into compiler errors, but instead of going the usual route of downloading the prebuilt package (kindly provided by GCenX), I decided to see if I could force it to build (since it was obviously buildable at some point). Down below is the list of things I had to do to make it work. Disclaimer: There are several dirty hacks I had to attempt to force the system to do what I needed. Use at your own risk. Don't forget to run all brew commands from a Rosetta prompt: arch -x86_64 zsh Install openssl This one is easy. Just run brew tap rbenv/tap brew install rbenv/tap/openssl@1.1 Install Command Line Tools 15.1 This specific version is required since newer versions come with the linker that is not compatible with the custom compiler (game-porting-toolkit-compiler) that GPTK is using. However, by default 15.1 tools won't install on Sequoia since the installer complains that macOS version is too new. Obviously, Apple has their reasons to not allow this, but all we need is a compiler which should be mostly indifferent to the OS version. To trick the installer, we need to change OS requirement of the installer package. You can do it in four easy steps: Copy Command Line Tools.pkg from the mounted Command_Line_Tools_for_Xcode_15.1.dmg to some other directory. Expand the installer package: pkgutil --expand "Command Line Tools.pkg" CLT You might be prompted to install Command Line Tools when you call pkgutil, just install any version. Go to the newly created CLT folder and edit the Distribution file (it may appear as executable but it's just an xml). You would want to change allowed-os-versions to something greater than 15. Removing this section altogether might also work. When done, re-wrap the package: pkgutil --flatten CLT "Command Line Tools 2.pkg" Congratulations, now you should be able to install 15.1 tools on your OS! If you had to install newer Command Line Tools for pkgutil, delete them before installing 15.1: sudo rm -rf /Library/Developer/CommandLineTools Next step is to make Homebrew accept the outdated 15.1 tools, as by default it'll complain that they're outdated or corrupted. To shut it up, open /usr/local/Homebrew/Library/Homebrew/extend/os/Mac/diagnostic.rb and remove references to check_if_supported_sdk_available from a couple of fatal build check collections. Note - by default, Homebrew will auto-update on any invocation, which will overwrite any changes you've made to its internals. To disable this behavior, before running any brew commands in the terminal, run export HOMEBREW_NO_AUTO_UPDATE=1 After these manipulations, Homebrew might still complain about outdated Command Line Tools, but it won't be a fatal error anymore. Finally, we need to downgrade MinGW to 11.0.1, since the latest version spits out compiler errors when compiling Wine. Unfortunately, Homebrew does a bad job tracking versions of MinGW, so there is no automatic way to do it. Instead, you have to manually download and install old MinGW 11.0.1 formula from the Homebrew git repository. I used the commit from Sep 16, 2023: https://github.com/Homebrew/homebrew-core/blob/b95f4f9491394af667943bd92b081046ba3406f2/Formula/m/mingw-w64.rb Download the file above, save it in your current working directory, and then run brew install ./mingw-w64.rb If you had a newer version of MinGW already installed from the previous build attempts, you can unlink it before installing the one above: brew unlink mingw-w64 With Command Line Tools 15.1 and MinGW 11.0.1 you should now be able to build GPTK without errors: brew -v install apple/apple/game-porting-toolkit In the end, steps above worked for me, although more things could break in the future. I'm leaving the instructions here just to show that it's still possible to build GPTK manually instead of relying on third parties, but with all the hoops I had to jump through I can't really recommend it.

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

Hello, **I'm Using ** Unity 6 LTS Unity Apple GameKit + Core plugins Turn-based matchmaking interface w/ 2 players max App Store Connect API for rule-based matchmaking I have already enabled game center in app store connect (I think) authenticated players and matched via friend request I am stuck Using queues to match players automatically I'm working on a rule-based matchmaking system which aims to place two players against each other into a GKTurnBasedMatch. I have a simple Unity Project that correctly authenticates a user and proceeds to send a matchmaking request. The matchmaking script utilizes the Unity plugins' GKTurnBasedMatchmakerViewController.Request(...) request function with a GKMatchRequest.Init() request configured with a QueueName equal to the App Store Connect API Queue I created. The queue I created is also linked to a ruleset with a very basic rule that checks if the properties contains a key called 'preference' that contains a string value for what side the player wants to play for this match. If during the matchmaking, the preferences between players are different, then the match is made and both players should join the match; each player gets to play the side they have chosen. I have my rule expression designed to just check if the preferences are not equal: requests[0].properties.faction_preference != requests[1].properties.faction_preference When I launch the game with two physical iPads and begin the matchmaking request, each player is immediately presented with two options: Invite a friend, or Start game The Problem: Inviting a friend works to get two players into a game, but queue seems to not matter, and clicking start game will just put the current player into its own match (no one joins). The Question: How do I get queue based matchmaking to work in Unity for a Turn-based match with only two players who are able to select the enemy side they want to play dictated by a rule that compares enemy play-side preferences? Resources I've used: Apple Unity GameKit Plugin: https://github.com/apple/unityplugins Matchmaking: https://developer.apple.com/documentation/gamekit/matchmaking-rules Multiplayer rulesets: https://developer.apple.com/documentation/gamekit/finding-players-using-matchmaking-rules

Hi there, I've discovered an issue with gesture handling in RealityKit when setting the camera’s fieldOfViewOrientation to horizontal. For instance, if I render a simple box at the center of the view with a collision shape that exactly matches its dimensions, the actual hit area behaves as if it's smaller than the box. Additionally, when attempting to drag the box away from the center, the hit area appears misaligned—offset slightly towards the center. Since the default fieldOfViewOrientation is vertical and everything works as expected in that mode, it seems that the gesture system might be assuming a vertical FOV. Given that the API allows setting it to horizontal, perhaps gestures should function correctly regardless of the orientation? Thank you!

How many 32-bit variables can I use concurrently in a single thread of a Metal compute kernel without worrying about the variables getting spilled into the device memory? Alternatively: how many 32-bit registers does a single thread have available for itself? Let's say that each thread of my compute kernel needs to store and work with its own array of N float variables, where N can be 128, 256, 512 or more. To achieve maximum possible performance, I do not want to the local thread variables to get spilled into the slow device memory. I want all N variables to be stored "on-chip", in the thread memory space. To make my question more concrete, let's say there is an array thread float localArray[N]. Assuming an unrealistic hypothetical scenario where localArray is the only variable in the whole kernel, what is the maximum value of N for which no portion of localArray would get spilled into the device memory? I searched in the Metal feature set tables, but I could not find any details.

I'm running into an issue with collisions between two entities with a character controller component. In the collision handler for moveCharacter the collision has both hitEntity and characterEntity set to the same object. This object is the entity that was moved with moveCharacter() The below example configures 3 objects. stationary sphere with character controller falling sphere with character controller a stationary cube with a collision component if the falling sphere hits the stationary sphere then the collision handler reports both hitEntity and characterEntity to be the falling sphere. I would expect that the hitEntity would be the stationary sphere and the character entity would be the falling sphere. if the falling sphere hits the cube with a collision component the the hit entity is the cube and the characterEntity is the falling sphere as expected. Is this the expected behavior? The entities act as expected visually however if I want the spheres to react differently depending on what character they collided with then I am not getting the expected results. IE: If a player controlled character collides with a NPC then exchange resource with NPC. if player collides with enemy then take damage. import SwiftUI import RealityKit struct ContentView: View { @State var root: Entity = Entity() @State var stationary: Entity = createCharacter(named: "stationary", radius: 0.05, color: .blue) @State var falling: Entity = createCharacter(named: "falling", radius: 0.05, color: .red) @State var collisionCube: Entity = createCollisionCube(named: "cube", size: 0.1, color: .green) //relative to root @State var fallFrom: SIMD3<Float> = [0,0.5,0] var body: some View { RealityView { content in content.add(root) root.position = [0,-0.5,0.0] root.addChild(stationary) stationary.position = [0,0.05,0] root.addChild(falling) falling.position = fallFrom root.addChild(collisionCube) collisionCube.position = [0.2,0,0] collisionCube.components.set(InputTargetComponent()) } .gesture(SpatialTapGesture().targetedToAnyEntity().onEnded { tap in let tapPosition = tap.entity.position(relativeTo: root) falling.components.remove(FallComponent.self) falling.teleportCharacter(to: tapPosition + fallFrom, relativeTo: root) }) .toolbar { ToolbarItemGroup(placement: .bottomOrnament) { HStack { Button("Drop") { falling.components.set(FallComponent(speed: 0.4)) } Button("Reset") { falling.components.remove(FallComponent.self) falling.teleportCharacter(to: fallFrom, relativeTo: root) } } } } } } @MainActor func createCharacter(named name: String, radius: Float, color: UIColor) -> Entity { let character = ModelEntity(mesh: .generateSphere(radius: radius), materials: [SimpleMaterial(color: color, isMetallic: false)]) character.name = name character.components.set(CharacterControllerComponent(radius: radius, height: radius)) return character } @MainActor func createCollisionCube(named name: String, size: Float, color: UIColor) -> Entity { let cube = ModelEntity(mesh: .generateBox(size: size), materials: [SimpleMaterial(color: color, isMetallic: false)]) cube.name = name cube.generateCollisionShapes(recursive: true) return cube } struct FallComponent: Component { let speed: Float } struct FallSystem: System{ static let predicate: QueryPredicate<Entity> = .has(FallComponent.self) && .has(CharacterControllerComponent.self) static let query: EntityQuery = .init(where: predicate) let down: SIMD3<Float> = [0,-1,0] init(scene: RealityKit.Scene) { } func update(context: SceneUpdateContext) { let deltaTime = Float(context.deltaTime) for entity in context.entities(matching: Self.query, updatingSystemWhen: .rendering) { let speed = entity.components[FallComponent.self]?.speed ?? 0.5 entity.moveCharacter(by: down * speed * deltaTime, deltaTime: deltaTime, relativeTo: nil) { collision in if collision.hitEntity == collision.characterEntity { print("hit entity has collided with itself") } print("\(collision.characterEntity.name) collided with \(collision.hitEntity.name) ") } } } } #Preview(windowStyle: .volumetric) { ContentView() }

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

If I compile a compute kernel with a call to texture.read(), it fails with the following error: "Error Domain=AGXMetalG13X Code=3 "Encountered unlowered function call to air.get_read_sampler" UserInfo={NSLocalizedDescription=Encountered unlowered function call to air.get_read_sampler}." This error occurs on both macOS and iOS 26 Beta 5, but not when running on a simulator or in a playground. It does not occur on a macOS Sequoia VM. It occurs whether I use the old metal 3 or new metal 4 compilation method. A workaround would be to use a sampler, but according to the feature tables, all platforms support reading from textures of all formats. Below is a minimal example which produces the error: let device = MTLCreateSystemDefaultDevice()! let library = device.makeDefaultLibrary()! let computeFunction = library.makeFunction(name: "compute_test")! do { let pipeline = try device.makeComputePipelineState(function: computeFunction) debugPrint(pipeline) } catch { debugPrint("Metal 3 failed with error:\n\(error)") } #import <metal_stdlib> using namespace metal; kernel void compute_test(uint2 gid [[thread_position_in_grid]], texture2d<float, access::read> in [[texture(0)]], texture2d<float, access::write> out [[texture(1)]]) { out.write(in.read(gid), gid); } I filed feedback FB19530049.

hello i am new to apple ecosystem and development i have some coding experience with c# now i like to develop my game for iphone 16 and up(due to ability to run ai models) but i am having hard time figuring out what to use there is a lot of resources for scene-kit but on its doc page it says its deprecated so i look at the reality-kit docs and tutorials and its strictly tells how to develop for visionos and i am really confused about this since there is no tutorials that shows how to develop a game for ios with reality-kit that does not focus visionos. i just want to develop for iphone 16 and up but i cant find resources focuses at that.
