New to achievements. I added them in App Store Connect and want to test them. Apple Documentation says this: "Before you begin testing your GameKit configuration, you need to enable Debug Mode. In Xcode, choose Product > Scheme > Edit Scheme. From the Run configuration, select Options and toggle Enable Debug Mode. To begin testing your achievement configuration, open the game Progress Manager. In Xcode, choose Debug > GameKit > Manage Game Progress." Sounds easy enough, but there is no "GameKit" under Debug in Xcode 16.2.

On an iPad running iPadOS 26 beta 4, when tapping the Game Center Access Point, the overlay doesn’t show the configured achievements, leaderboards or challenges. I should specify this is an in-development app and the achievements and leaderboards are in the “Not Live” state, however they show on other devices running iOS 18 in the Access Point UI. Anyone else having this issue? If so, how should I test achievements and leaderboards while iOS 26 beta is out? The UI looks like this on iPadOS 26:

Hello — I shipped an App Store build that signs in to Game Center using the Apple Unity Plugins (GameKit). The login banner appears, but my app still doesn’t show up in Game Center’s “All activity” (You started playing *** 2d ago) What I’ve done Call await GKLocalPlayer.Authenticate(); “Game Center” is enabled for the current version in App Store Connect Confirmed: other App Store games do appear under “All Activity” on the same device/account Timeline: This is the first version that enables Game Center (not the app’s first release), and it has been about 2 hours since this build went live. Questions Is authentication alone sufficient for “Recently Played,” or is at least one Game Center component (leaderboards, achievements, activities, multiplayer) required? Is there a typical propagation delay before “Recently Played” starts showing a newly enabled app/version? Is there anything else I should configure in App Store Connect or entitlements to make “Recently Played” visible? Thanks for any help.

I would like a monthly recurring leaderboard, but the most days one can set for the recurring leaderboard is 30, and some months have 31 days (or 28/29). This is dumb. I guess I have to manually reset a classic leaderboard each month to get this result? Additionally once it closes and is about to reset (I also have daily recurring leaderboards), I'd like to grant the top placers on the leaderboard a corresponding achievement, but I don't see any way of doing this. I believe I can do all these things on PlayFab, but it'll take a bit more work, and eventually cost. Any one have advise?

I’m running into unexpected problems with the Unity GameKit plugin setup with the new Activities. I didn’t see anyone else mentioning these issues, so my guess is that it’s a problem with my setup. The authentication (GKLocalPlayer.Authenticate()) works as expected, but any call to the new GameActivity functionality (e.g. GKGameActivityDefinition.LoadGameActivityDefinitions() or GKGameActivity.WantsToPlay) gives me an exception with a 'UnsupportedOperationForOSVersion' reason despite it running on an iOS 18.6.1 device. I’m using a completely empty Unity 2022.3.62f1 project that only contains the official authentication example, followed by an event handler for activities from another example and the Unity core and gamekit plugins. The setup: macOS 15.6 Xcode 26 beta 6 (also tried with 5) Physical iPhone device running iOS 18.6.1 Unity 2022.3.62f1, which satisfies the requirements Unity plugin, Xcode setup, and build steps: I Followed the official beta branch build steps for Unity plugins with python3 build.py -m iOS iPhoneSimulator macOS -p Core GameKit which ran through after a slight modification for the macOS target that somehow contained an unknown team reference for the GameKitWrapper project, which I changed to not reference a team and use ‘sign to run locally’, as was the case for the other packages. As far as I understood the macOS version is not strictly necessary either way just for running it on a local iOS device(?) I Imported these as tarball packages into the empty Unity 2022.3.62f1 project as per the official instructions, which seems to work as expected Added a single script with the mentioned example code added in a MonoBehavior.Start Building in Unity works as expected as well, creating the Xcode project The Unity-iPhone target has the GameKit framework linked (’do not embed’) and the GameCenter capability was added automatically as expected The GameKit framework seems to not be added to the UnityFramework target, but I don’t think this is necessary? Quickly testing this with the GameKit framework added there as well didn’t make a difference The linked GameKit framework is indeed the expected Xcode 26 beta version I can then build and run this on the physical iPhone iOS 18.6.1 device, where I get an ‘UnsupportedOperationForOSVersion’ as soon as I try to subscribe to deeplinking events (GKGameActivity.WantsToPlay) or use other GameKit Activity functionality from the official examples: // log showing that it's actually running on iOS 18.6: [Apple.Core Plug-In Runtime] Availability Runtime Environment: iOS 18.6 Apple.Core.Availability:OnApplicationStart() // and the exception I get: GameKitException: Code=-7 Domain=GKErrorDomain Description=The operation couldn’t be completed. (GKErrorDomain error -7.) (UnsupportedOperationForOSVersion) at Apple.GameKit.DefaultNSErrorHandler.ThrowNSError (System.IntPtr nsErrorPtr) [0x00000] in <00000000000000000000000000000000>:0 Rethrow as TypeInitializationException: The type initializer for 'Apple.GameKit.GKGameActivity' threw an exception. I unfortunately didn’t find any clues as to why this happens and how to resolve it on this forum or otherwise. Changing the minimum iOS version - up to 18.6 from the previously used (Unity export default) 12.0 for any and all targets - did not yield a different result I'd rather not update the phone to use the iOS 26 beta, though as far as I understood this is not necessary Any pointers to what I might be missing or doing wrong are greatly appreciated! Thank you very much in advance!

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

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?

Hello, When testing GameKit "Manage Game Progress" in Xcode 26: On iOS devices, achievements, leaderboards, and party code data display and work correctly. On macOS devices, none of these data appear in "Manage Game Progress." Is this a known issue with macOS GameKit, or is there a limitation compared to iOS? If it is not a bug, is there any additional configuration needed to make achievements and leaderboards visible on macOS? I also included the GameKit bundle in my macOS app and enabled Enable Debug Mode in GameKit Configuration in the scheme options. Thank you.

Hello - Upon enabling debug mode for GameKit configuration for my iOS app, I do not see any devices (my iPhone or simulators) in the device list within the "Manage Game Progress" debug tool. I only see my Mac as a device. Is there any trick to this or a way to add devices to this list? Thank you

Hi all I have two mystic issues with saving and fetching data to and from iCloud. Both repro only after first launch of an app. 1. [GKLocalPlayer fetchSavedGamesWithCompletionHandler:] After first attempt I can see 0 saved games (but i know that there is at least one saved game) and there is no any error. In case if I try fetch one more time (without any additional actions) even immediately after first attempt I receive saved games correctly (not 0) 2. [GKLocalPlayer saveGameData: withName: completionHandler:] After first attempt I can see error The requested operation could not be completed because local player has not been authenticated. In case if I try save one more time (without any additional actions) even immediately after first attempt I can save data successfully without any error I found the same issue in StackOverflow, but there are no fixes...

I just built Core and GameKit without errors. The command line I used was the following: python3 build.py -p Core GameKit -m macOS -c "Apple Development ID (redacted)" When importing these packages into Unity, as soon as the editor refreshes I get these errors: DllNotFoundException: GameKitWrapper assembly:<unknown assembly> type:<unknown type> member:(null) And DllNotFoundException: AppleCoreNativeMac assembly:<unknown assembly> type:<unknown type> member:(null) And Apple Unity Plug-ins] No Apple native plug-in libraries found. Were the libraries built with the build script (build.py), xcodebuild, or Xcode? Was any output generated from the build script/tool? Were there any errors or issues? Please check to ensure that libraries (.a, .framework, or .bundle files) were created and saved to each plug-in's "NativeLibraries~" folder. I made sure that the libraries were saved to this NativeLibraries folder. I made sure to update xcode, python, npm and Unity to the latest version, got the most recent commity from Github (Sept. 17th) but the errors persist. The errors also occur right as the game starts in a built player. Also occurs in a blank Unity project, where I tested both 2022.3.17f and 2022.3.48f. The versions I was trying to import was Core 3.1.4 and GameKit 3.0.0. Same issue with Core 3.1.3 and Gamekit 2.2.2. Last version I tried that works was Core 1.05 and GameKit 1.04. I haven't seen anyone else encounter this on these forums so I'm guessing that I'm personally doing something wrong rather than there being an issue with the plugins themselves, but what am I doing wrong?

I'm displaying a GKGameCenterViewController after successfully authenticating and on iOS 18.0 and 18.1, I get a black screen. As a sanity check GKLocalPlayer.local.isAuthenticated is also returning true. The same code works just fine on iOS 17. Is there something that needs to be done on iOS 18 and above?

Hi, I tried to save the game progress using the official Apple plugin for Unity but the crash happened when I active the "iCloud Documents" inside capabilities and when deactivated it this error message appeared: Code=27 Domain=GKErrorDomain Description=The requested operation could not be completed because you are not signed in to iCloud or have not enabled iCloud Drive. (UbiquityContainerUnavailable) Authentication with Game Center works fine using the Core plugin, but nothing works correctly when I use the GameKit plugin. Note: I already active iCloud for app Identifier. Tichnecal informations: Unity version: 2022.3.47f1 LTS XCode 16 Swift 6 GameKit-3.0.0 (Apply unity plugin) Core-3.1.5 (Apply unity plugin)

I am currently working on a game that involves earning achievements, which I am using the Apple Unity Plug-Ins to display. I have found that occasionally opening the Game Center Dashboard the last achievement earned will not be displayed until the game is closed and reopened. I am using GKAccessPoint.Shared.Trigger to display the Achievements screen, which occasionally seems to open a cached version of the dashboard. I've found that it seems to consistently happen when earning multiple achievements within one minute, but this is not always the case. Does anybody have any experience with something like this in the past?

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.

When running my game in the Unity Editor on Windows platform I get an error: DllNotFoundException: GameKitWrapper assembly:<unknown assembly> type:<unknown type> member:(null) Apple.GameKit.DefaultNSErrorHandler.Init () (at ./Library/PackageCache/com.apple.unityplugin.gamekit@0abcad546f73/Source/DefaultHandlers.cs:35) This is because GameKitWrapper dynamically linked library is not available under Windows platform. Besides, "Apple Build Settings" are declared under UNITY_EDITOR_OSX and also not available under Windows platform. Does anyone managed to solve this?

Hey all — I’ve been building out my first set of Game Center Achievements for a game I’m working on, and I’ve run into something odd with the image quality. The specs say to upload icons at 512x512 or 1024x1024@2x. I’ve been uploading 1024x1024 PNGs (without explicitly naming them “@2x” since there’s only one upload slot), assuming that Game Center would just handle the scaling automatically — kind of like how a lot of things are getting more streamlined across platforms lately. But in testing, the icons are showing up a bit blurry, especially in the Game Center interface. It’s not horrible, but it’s definitely softer than I expected — more like low-res than Retina. All my test devices (outside the Simulator) are running iOS 26, so I’m also wondering if this might be a beta-related display bug? Has anyone else run into this? Curious if I’m missing a best practice here, or if I really do need to ensure I’m uploading it with the @2x suffix, or maybe something else entirely? Thanks!

I'm having issues getting a well built package from the Apple Unity Plug-in project. When building the my game project in Unity the following error is printed to the console: Apple.Core.AppleNativeLibraryUtility] Cannot locate a Debug or Release Apple.Core native library for iOS. Please ensure that the build invocation (build.py, xcodebuild, or Xcode) compiled cleanly and that the build was configured to support Debug on iOS. As far as I can tell the build did compile cleanly, but I might be missing something. If anyone can see what I'm doing wrong or has any insight it would be greatly appreciated. Setup is the following: macOS Tahoe 26 Beta Xcode-beta Version 26.0 beta 3 (17A5276g) Unity Plug-in branch: 2025-beta1 Unity game project version: 2022.3.60f M1 Macbook Pro The built packages have been imported into the game project through the Unity Package Manager using the tarball option pointing to the built packages from the Unity Plug-in project. The Unity Plug-in project has been built using the build.py file with the following: python3 build.py -m iOS iPhoneSimulator -p Core GameKit CoreHaptics GameController -k all The output is available in the attached file. build-output.txt Here's an image of the NativeLibraries~ folder inside the built Apple.Core package.

Hi, Since iOS 26 introduced the new Games app, I’ve noticed a problem when using a Nintendo Switch Pro Controller in wired USB-C mode, and also with third-party controllers that emulate it (like the GameSir X5 Lite). In the Games app interface, only the L/R buttons respond, but the D-Pad and analog sticks don’t work at all. Once inside actual games, the controller works fine — the issue only affects the Games app UI. What I’ve tested so far: Xbox / PlayStation controllers → work fine in both wired and Bluetooth, including inside the Games app. Switch Pro Controller (Bluetooth) → works fine, including in the Games app. Switch Pro Controller (wired) → same issue as the X5 Lite, D-Pad and sticks don’t work in the Games app. This makes it hard to use the new Games app launcher with these controllers, even though they work perfectly once a game is launched. My question: is this an iOS bug (Apple needs to add proper support for wired Switch Pro controllers in the Games app), or something that Nintendo / GameSir would need to address? Thanks in advance to anyone who can confirm this or provide more info.

We have a released game in the App Store with Game Center Challenges. The challenges were working well in testing of the final version before the Game Center challenges went live. After release the activity that should take the player to the challenge in game results in this printout and we do not get informed by GKGameActivityListener of the activity happening in our code as we did before the Game Center challenges went live. “Invalid game activity definition. Failed to kick activity notification to GameKit. Error: Error Domain=GKErrorDomain Code=17 "(null)"” Also, Game Center reports that the are no challenges in GKChallengeDefinition.all even though there are ongoing challenges. The leaderboard results do get reported to Game Center though and show up as challenge entries in the Games app. At the moment we are trying to figure out if this is a problem on our end or a Game Center server issue.
