Hi, I'm trying to add game center challenges and activities to an already live game, but they are not appearing in game for testing, GameCenter, or the Games app. I know the game is setup with GameKit entitlements since this is a live game and it has working leaderboards and achievements. I've updated to Tahoe beta 8, added a challenge and activity on app store connect, added that to a new distribution and added that distribution to 'Add for Review' I'm using Unity and the Apple Unity plugin Not sure what other steps I'm missing Thanks

I’m testing Game Activities in my Unity project with the new Apple.GameKit 2025-beta1 plugin. When I go into Xcode- Debug → GameKit → Manage Game Progress → Leaderboards → and click the generated link: If my app is already running in the background, the link opens the app and my handler (Apple.GameKit.GKGameActivity.WantsToPlay += OnWantsToPlay;) fires as expected. I can read the activity and route the player to the right level. If the app is completely closed, clicking the same link launches the app, but my OnWantsToPlay listener is never invoked. The app just boots normally and the activity intent seems lost. I’ve tried to subscribe as early as possible (in Awake() of my bootstrap scene, also tested with RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]). Nothing works. Also, “Get Started with Game Center” video only demonstrates activation when the app already running, not a cold start from a Game Activity link. What am I missing?

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?

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?

Hi, I am trying to load files from the Apple Vision Pro's storage into a Unity App (using Apple visionOS XR Plugin and not PolySpatial package). So far, I've tried using UnitySimpleFileBrowser and UnityStandaloneFileBrowser (both aren't made for the Vision Pro and don't work there), and then implemented my own naive file browser that at least allows me to view directories (that I can see from the App Sandbox). This is of course very limited: Gray folders can't be accessed, the only 3 available ones don't contain anything where a user would put files through the "Files" app. I know that an app can request access to these "Files & Folders": So my question is: Is there a way to request this access for a Unity-built app at the moment? If yes, what do I need to do? I've looked into the generated Xcode project's "Capabilities", but did not find anything related to file access. Any help is appreciated!

I am using the latest version of the Game Center plugin for Unity and have noticed that my game will crash on launch when trying to authenticate. I've tried this in an empty project with just the plugin and it still crashes with this exception. GfxDevice: creating device client; threaded=1; jobified=0 Initializing Metal device caps: Apple A14 GPU Initialize engine version: 2022.3.62f2 (7670c08855a9) GameKitException: Code=-7 Domain=GKErrorDomain Description=The operation couldn’t be completed.

And the area in the native code that is triggering the crash is this inside the GKLocalPlayer_SetAuthenticateHandler function `_onAuthenticate!(tid, _mostRecentAuthenticatePlayer!.passRetainedUnsafeMutablePointer()); I am using Unity 2022.3.62f2 and MacOS 15.6 with iOS 18.6.2 which based on the min specs for the plugin we should be within spec. I have also included this message because I thought it might help too `terminating due to uncaught exception of type Il2CppExceptionWrapper Could not import Swift modules for translation unit: failed to get module "GameKitWrapper" from AST context: error: 'GKErrorCodeExtension.h' file not found in file included from :1: error: could not build Objective-C module 'GameKitWrapper' warning: Ignoring missing VFS file: /Users/james/Library/Developer/Xcode/DerivedData/GameKitWrapper-dzawbtxqdxdviiakfxmfunexppqv/Build/Intermediates.noindex/GameKitWrapper.build/Release-iphoneos/GameKitWrapper-bc72bd3638f4d2956cac9b00e84c1a7d-VFS-iphoneos/all-product-headers.yaml This is the likely root cause for any subsequent compiler errors.warning: Ignoring missing VFS file: /Users/bill/Library/Developer/Xcode/DerivedData/GameKitWrapper-dzawbtxqdxdviiakfxmfunexppqv/Build/Intermediates.noindex/GameKitWrapper.build/Release-iphoneos/GameKitWrapper iOS.build/unextended-module-overlay.yaml This is the likely root cause for any subsequent compiler errors.warning: TypeSystemSwiftTypeRef::GetNumChildren: had to engage SwiftASTContext fallback for type $syyXCD I've also attached the script that I am using for authentication, this script runs on the first scene.

What is required to make Early Reflection and Late Reverb take effect on a visionOS device build? action taken ・created a SoundEvent. ・in composer, created a Sampler and a SpatialMixer; attached an AudioClip to the Sampler; enabled Direct Path, Early Reflection, and Late Reverb on the SpatialMixer. ・attached a PHASE Source to the object to be played, attached the created SoundEvent to it, and set non-zero values for Early Reflection and Late Reverb. ・attached a PHASE Listener to the mainCamera and set the ReverbPreset to a value other than None. ・in project settings > Audio, set Spatializer plugin to PHASE Spatializer. ・from there, build for visionOS.

This is using: **Unity 6000.2.7f - latest ARKit etc Xcode 26.1 ** This is going to iPad/iPhone/iOS and I have succesfully built to the iPad before, but updates to the software seem to have added these errors in.

Even when making a completely fresh Unity project, if I include ARKit and upload it to testflight, when I open it on my ipad it says 'Couldn't Load App'. If I don't include testflight the app opens fine. If I build the app directly to my ipad the app works fine. It opens if I set ARKit to 'optional' but then the AR doesn't work. I have included a camera and location usage description so it's not that. Really not sure what's going on, any help would be massively appreciated!
