Leaderboard has not worked for past two days. What’s up with that?

I have created a turn based game using GameKit. Everything is pretty much done, last thing left to do is the turn time out. I am passing GKTurnTimeoutDefault into the timeout argument in: func endTurn(withNextParticipants nextParticipants: [GKTurnBasedParticipant], turnTimeout timeout: TimeInterval, match matchData: Data) However when I check the .timeoutDate property of the GKTurnBasedParticipant participants, the value is always nil. What am I doing wrong? Am I checking the right property or is there another one instead that I don't know about? I have tried passing different values to the timeout parameter but the timeoutDate is always nil. Has anyone successfully implemented a timeout using GKTurnBasedMatch ?

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?

Hello, I’m working with the GameKit API, and I am encountering an issue when submitting a player’s score to a leaderboard at the end of a game. Goal: After submitting the new score to a leaderboard, I want to immediately fetch and display the updated leaderboard that reflects the new score. Problem: After successfully submitting the player’s score, when I fetch the leaderboard, the entries are not updated right away. The fetched leaderboard still shows the outdated player score. Is this delay in updating the leaderboard expected behavior, or am I missing something in my implementation? Steps to Reproduce: Submit the local player’s score to Leaderboard X. On successful submission, fetch the leaderboard entries for Leaderboard X. Expected Result: The fetched leaderboard should reflect the updated player score immediately. Actual Result: The fetched leaderboard shows the outdated score, with no immediate update. As a workaround, I update the leaderboard myself locally, that does the job, but is error-prone and require more efforts.

Hi, I created a leaderboard in my application, and a method to record a new score: GKLeaderboard.loadLeaderboards(IDs: [leaderboardID]) { (leaderboards, error) in if let error = error { print("Error loading leaderboards: \(error.localizedDescription)") } guard let leaderboard = leaderboards?.first else { print("Leaderboard not found") return } leaderboard.submitScore(score, context: 0, player: self.localPlayer) { error in if let error = error { print("Error reporting score: \(error.localizedDescription)") } else { print("Score reported successfully!") } } } } When debuging, this method is correctly called and I have a success, so I tried to test it with an internal TestFlight release. The leaderboard is never updated. Is there a way to perform a test of a leaderboard before publishing the app? I have the same question for achievements: let achievement = GKAchievement(identifier: identifier) achievement.percentComplete = percentComplete GKAchievement.report([achievement]) { error in if let error = error { print("Error reporting achievement: \(error.localizedDescription)") } } } Thanks!

Hello, Asking the following as, I was unable to find answers via search on the forum and in the documentation: Invitations sent via iMessage seem to work correctly with my custom image ( GKMessageImage.png ) however, notifications sent to Game Center Friends via invites generated in Game Center do not include the custom image ( GKMessageImage.png ). Questions: Is this expected behavior? Is there a different way to customize the image in the notification? Note the Game Center notification includes the App name correctly. I also noted in the WWDC session in 2016 ( saw video recently ) that there was some mention of no longer adding friends via Game Center. Is that currently true? Thanks in advance.

Hello, I would like to know if anyone has or still using the GKVoiceChat capabilities in their apps. I wanted to use it for my online game but I am coming across issues using it and wondering if their are alternatives?. The documentation mentions to use Share-play but that wont be possible with random online players. Any help will be appreciated!.

Hello, I try to invite a friend to play my app , however when the friend try to press invite link component via iMessage, it shows “Retrieving” and then disappear, nothing happens, it doesn't redirect to my app, what I'm missing? or doing wrong I can leave some part of my code import Foundation import GameKit extension RealTimeGame: GKLocalPlayerListener { /// Handles when the local player sends requests to start a match with other players. func player(_ player: GKPlayer, didRequestMatchWithRecipients recipientPlayers: [GKPlayer]) { print("\n\nSending invites to other players.") } /// Presents the matchmaker interface when the local player accepts an invitation from another player. func player(_ player: GKPlayer, didAccept invite: GKInvite) { // Present the matchmaker view controller in the invitation state. if let viewController = GKMatchmakerViewController(invite: invite) { viewController.matchmakerDelegate = self rootViewController?.present(viewController, animated: true) { } } } } also I don't have "<key>CFBundleURLTypes</key>" in my info.plist, I don't know I need that or not...

Why is the GameController framework loaded I am checking the launch time of our app, using Instruments->App launch I was confused to find the GameConroller framework loaded I check the project, in the plist file, no configuration GCSupportedGameControllers, GCSupportsControllerUserInteraction related key. What else causes the GameController framework to load?

I'm using the Apple Unity Plugins to use Game Center to authenticate Playfab accounts for my game and when I test this on testflight, everything works fine for me and the people I've tested with, however, when I send the build to review, they are getting GameKitException 37 which states "This game is not listed in a marketplace that supports Game Center" and upon further research I found this page https://developer.apple.com/documentation/gamekit/gkerror/code/appunlisted which I'm assuming is the same thing. This seems to suggest that I need my app to be listed on the App Store which is strange because this has created a what comes first, the chicken or the egg problem. I need to pass review to get the game listed in the App Store and they can't test the game because accounts cannot be authenticated with Game Center which apparently needs to be listed on the App Store. So far, I can't find the reason why this doesn't happen on testflight and only happens when I send it to review. I opened a ticket to Apple Developer Support and haven't recieved a response. I asked app review about it and they replied "Hello, Thank you for your response. Since all apps must pass App Review before they can be approved, it should not be necessary to have a "store page". We look forward to reviewing your app once all issues have been addressed and the new build has been received and queued for review. Best regards, App Review" Which doesn't really help me. I am quite pressed for time and I really need assistance in resolving this issue which I cannot replicate. Has anyone encountered this issue or know how to solve it?

Hello, has anyone been able to implement in their game a way to display the number of players currently online in their game?. I thought up of this feature and thought it will be useful for players to find out if there is anyone currently online so that they don't waste their time trying to find a random online match. Any help will be greatly appreciated. Kind regards, Jabir Abdi

I have a VisionOS app that uses a Game Center Leaderboard. On 'appear' of my content view, I check authentication, and if the user is auth'd, I display a 'leaderboard' button. This works on development / TestFlight – the little floating 'Game Center logged-in' pop up shows up when the app runs, and the button appears. Tapping the button opens the leaderboard, and I can tap over to 'global' and see everyone's scores. However, the app launched today on the App Store, and I'm having some issues. The leaderboard button isn't showing up, meaning that the auth call is probably failing silently. Not sure why. If I log out of Game Center on the device, and re-open the app, I'm able to auth and see my leaderboard button. Once I've done that, the leaderboard seems busted. On App Store Connect I can see the values that I expect (high scores from my beta test flight). But, on the production app, the leaderboard is just empty. And there's no 'global' tab to tap on. Wondering if this is a propagation issue? Like, does it take time to roll out the Game Center entitlements when the app is live? I'm going to distribute promo codes to try and get some more people with the App Store version testing for me to see what happens for them. Any help appreciated!

This may be a bit dumb but I've really been having trouble with understanding the documentation for Apple's Unity Plugins. I wanted to implement Game Center functionality on my game. So far the only line of code I've managed to get working is the authentication, in which I did async void Start() { await Login(); } public async Task Login() { if (!GKLocalPlayer.Local.IsAuthenticated) { var player = await GKLocalPlayer.Authenticate(); var localPlayer = GKLocalPlayer.Local; ] } However, I'm at a complete loss as to how to open leaderboards. I followed the documentation given: void OpenLeaderboard() { var allLeaderboards = await GKLeaderboard.LoadLeaderboards(); var filteredLeaderboards = await GKLeaderboard.LoadLeaderboards("leaderboardIwant1"); } But it did not work. What did I do wrong? Am I missing a function to get it to work? Why can't Apple write proper documentation to properly implement this in a simple way? My apologies for my frustration. Up until now I've used another plugin from the Unity Asset Store which is shockingly easy to use, but I decided to attempt to use Apple's system because the plugin I had used deprecated functions and I was afraid the App Store would not approve it. But Apple's own plugins are stunningly opaque and hard to test. As additional questions (but not the main ones), I'm also completely at a loss how to submit scores or load specific leaderboards and Apple's documentation does nothing to help there either. Any help or thoughts are appreciated. Thanks.

In the last several days I've gotten reports from customers saying that Game Center suddenly cannot connect to players. I was able to verify this myself. It will find players to match, but then during the Connecting process it just sits there indefinitely with a spinning thing. Up until maybe 4 days ago this had worked fine for the last 12+ years, so something on the Game Center server broke. Is anyone else experiencing the same problem?

Now I am using iOS 16 beta 6, I can get buttonA/buttonB is pressed event. but cannot get accelerator motion data info.      //work     buttonA?.valueChangedHandler = {(_ button: GCControllerButtonInput, _ value: Float, _ pressed: Bool) -> Void in       print(">>> ButtonA tapped")     }     //work     buttonB?.valueChangedHandler = {(_ button: GCControllerButtonInput, _ value: Float, _ pressed: Bool) -> Void in       print(">>> ButtonB tapped")     }           // this is not works     gameController.motion?.valueChangedHandler = { (motion: GCMotion)->() in       print(">>>> motion data \(motion.acceleration.x) \(motion.acceleration.y) \(motion.acceleration.z)")       if let delegate = self.motionDelegate {         delegate.motionUpdate(motion: motion)       }     } Is there any plan to support this?

At WWDC 2023, the background asset feature was introduced, allowing essential resources to be downloaded before the game is first launched. How does this differ from including all necessary resources directly in the installation package? What are the advantages of this approach, and how does it enhance the user experience?

https://vimeo.com/957974306 Canvas #1(Unity) stopped rendering context when I switch tab on inspector. Also my device 13 pro max running iOS 17.5.1 lost context when I screenshot. It has no log in console. Not happened on 13 pro max running iOS 16.4

Dear Apple Developer Support, I have a question regarding the Background Assets feature for a game we are planning to release on the App Store. Specifically, I would like to understand the user experience during the initial installation process. If our game utilizes the Background Assets feature and we have essential assets specified in the BAExtension, will the end user need to wait for these essential assets to be fully downloaded before they can open the game after installing it from the App Store? Additionally, during this download process, will there be any indication of the essential assets' download status on the App Store or on the home screen icon of the game? Your guidance on how this process is managed and what the user can expect would be greatly appreciated. Thank you for your assistance.

Hello, First of all, I understand that GKVoiceChat has been deprecated and replaced by shareplay but for my situation, it does not seem useful as I will be matching with the random players hence I can not utilise the Facetime(Shareplay) capability. I have set up a voice chat function using the GKVoiceChat object, my game connects with another player successfully but the voice chat does not work for some reason. The code snippet below is how I implemented it with the help of the tutorial from : apple (Start Voice chat between players) class OnlineGame { var voiceChat: GKVoiceChat? = nil ... // When online game succesfully connected and game view loaded self.startVoiceChat() func startVoiceChat() { // Handle an unknown, connected, or disconnected player state. /// - Tag:voiceChatChangeHandler /// if voiceChat == nil { // Create the voice chat object. voiceChat = myMatch?.voiceChat(withName: "Gamesession") } let voiceChatChangeHandler = { (player: GKPlayer, state: GKVoiceChat.PlayerState) -> Void in switch state { case GKVoiceChat.PlayerState.connected: self.voicechatstate = 1 case GKVoiceChat.PlayerState.disconnected: self.voicechatstate = 2 case GKVoiceChat.PlayerState.speaking: self.voicechatstate = 3 case GKVoiceChat.PlayerState.silent: self.voicechatstate = 4 case GKVoiceChat.PlayerState.connecting: self.voicechatstate = 5 @unknown default: print("Player unknown state.") } } // Exit early if the app can't start a voice chat session. guard let voiceChat = voiceChat else { return } // Handle an unknown, connected, or disconnected player state. voiceChat.playerVoiceChatStateDidChangeHandler = voiceChatChangeHandler // Set the audio volume. // Activate the shared audio session. do { let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(AVAudioSession.Category.playAndRecord, mode: AVAudioSession.Mode.gameChat, options: AVAudioSession.CategoryOptions.allowBluetooth) try audioSession.setActive(true, options: []) } catch { print("ERROR: \(error.localizedDescription).") } voiceChat.volume = 0.8 voiceChat.start() voiceChat.isActive = true } } Thats my implementation of it and hope it explains my issue. Thanks for your assistance in advance!.

GKLocalPlayer.local.authenticateHandler = {viewController, error in When authenticating a player using authenticateHandler, the completion handler is only called if the player is already logged in. If the player is not logged in, the authentication window will appear but the completion handler is never called. If I have content in a volumetric window that obscures the login window (which appears at a slight Z increase from the parent window), what can I do? If the completion handler was being called then I could make adjustments to my view, but it never gets called if the user is not already logged in. https://developer.apple.com/documentation/gamekit/authenticating_a_player Thanks.
