Hello, I setup a leaderboard in the default language English and everything works and the app is live in the store. Now I am adding localization to the leaderboard and noticed than some languages have the data entry "Score Format Suffix" and some languages the data entries "Score Format Suffix (Singular)" and "Score Format Suffix (Plural)" instead. Is this an error or intentional? Kind Regards, Chris

I have an idea for a game where the Apple TV app acts as the host and discovers nearby iOS apps that can join the game. Each iOS app needs to be able to have the user draw, tap, etc and have all the events be delivered in real time to the Apple TV where the effects will be rendered immediately (imagine a co-op game played in your lounge room where guests user their own devices to control aspects of the UI on the shared Apple TV screen) MPC is discontinued and DeviceDiscoveryUI is limited to only a single iOS device so I’m trying to figure out the best way to do the P2P networking. Reading/watching videos suggests that using GKMatchMaker and friends seems like it might suffer from latency problems (because everything has to go via Game Centre - or does it?) plus I’m not sure how I’d deal with the fact that the owner of the Apple TV is likely to signed into the same game centre id on both the Apple TV and their own devices to which would mean they wouldnt be able to play because the host can’t invite “themselves” on another device (or can it?) Soooo… I’m looking for suggestions on how best to move forward. I’ve read https://developer.apple.com/documentation/technotes/tn3151-choosing-the-right-networking-api which is very useful but there’s no clear suggestion that would work. Using the Network for the real time messaging seems doable but dealing with discovery / invites seems like a massive pain that I’d prefer to use built-in libraries if possible. Any suggestions would be gladly received. Thanks a lot

Hello, I’m the developer of the “ StepSquad” app. Our app uses the Game Center achievement feature, but we’ve been encountering a problem: the “Global Players” metric always shows 0%, even though there are friends who have already achieved these achievements. Initially, I thought it might be because the app was newly launched. However, it’s now been over two months since release, and it’s still showing 0%. If anyone has any insight into this issue, please leave a comment.

I facing to many lags in pubgmobile when i m playing its not running properly

I am developing a turn based game using GameKit. The happy path (pretty much as always) is fine; invite, accept, play, have winners/losers and match ends. Yay! But I am working on making sure I handle situations where invited friends decline to participate. I've been through the docs, and don't see how the GKTurnBasedMatch is updated to reflect the tap of the decline button in the Game Center Invite notification. When I reload the match from Game Center on the host device the status for the invitee who declined is still .invited. I also tested by setting all players that are not the host in the nextParticipants of the endTurn(...) to start the invites and the next invitee was not given a push notification to accept or decline the invite. I feel like there should be a way to determine when an invitee has declined an invite (via participant in the match.participants via status OR a delegation method somewhere that is called when the Decline or Accept buttons on that notification are tapped.) I'm missing something, please help me find it! Thank you!

i was update my iPhone 15 pro max on IOS 18.2 beta versio. I am fasing the issu. When i am playing Pubg Game, the notification always Come down and game stop. And when i try to On “Guided Access” the Guided access also not workin. Plzzz fix it.

If it’s possible the “Go Back” option is available on both left and right side. right hander also easily use iPhone on One hand. give us a option “Go Back” option on Right also. Its very easy for us. Thank u soo much🩷🩷

Hi, I’m creating a game and I’m just wondering if I can integrate GCVirtualController in my SwiftUI app.

In my SceneKit game I'm able to connect two players with GKMatchmakerViewController. Now I want to support the scenario where one of them disconnects and wants to reconnect. I tried to do this with this code: nonisolated public func match(_ match: GKMatch, player: GKPlayer, didChange state: GKPlayerConnectionState) { Task { @MainActor in switch state { case .connected: break case .disconnected, .unknown: let matchRequest = GKMatchRequest() matchRequest.recipients = [player] do { try await GKMatchmaker.shared().addPlayers(to: match, matchRequest: matchRequest) } catch { } @unknown default: break } } } nonisolated public func player(_ player: GKPlayer, didAccept invite: GKInvite) { guard let viewController = GKMatchmakerViewController(invite: invite) else { return } viewController.matchmakerDelegate = self present(viewController) } But after presenting the view controller with GKMatchmakerViewController(invite:), nothing else happens. I would expect matchmakerViewController(_:didFind:) to be called, or how would I get an instance of GKMatch? Here is the code I use to reproduce the issue, and below the reproduction steps. Code Run the attached project on an iPad and a Mac simultaneously. On both devices, tap the ship to connect to GameCenter. Create an automatched match by tapping the rightmost icon on both devices. When the two devices are matched, on iPad close the dialog and tap on the ship to disconnect from GameCenter. Wait some time until the Mac detects the disconnect and automatically sends an invitation to join again. When the notification arrives on the iPad, tap it, then tap the ship to connect to GameCenter again. The iPad receives the call player(_:didAccept:), but nothing else, so there’s no way to get a GKMatch instance again.

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'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?

Once GKAccessPoint is active, then enter an arview page, the arview will lose camera feed. OSVersion: iOS 18.0.1, iOS 18.1

The welcome banner is off the top left side of the screen instead of coming down the center. This behavior is encountered when running my iOS application on macOS.

The update was the only change I can see. Which I did just the other day. I did log on to iCloud.com, I also looked at Apple Developer. I didn't see any additional updates of terms that needed to be accepted. I am sure to log into iCloud on the simulator. It seems to stay logged in. Until I fetchSavedGames. Where I have it exit at 20 seconds due to timing out. Then when I go back to check my account in Settings, it's asking to "Sign in to iCloud" again. It does work properly on a device. So it doesn't stay logged into iCloud on the simulator but it seems like the fetchSavedGame from GKLocalPlayer is what resets that. Any help or suggestions would be appreciated. Thanks.

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.

When opening the Game Center dashboard via the Access Point, the Game Center dashboard appears BEHIND any content in the window with z depth (default type not volumetric). It obscures the dashboard and this makes it unusable. Alerts have the same placement. The new defaultWindowPlacement would probably suffice, but I don't think there's a way to apply that to the Game Center window. What to do? Thanks.

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, I would like to know if anyone has or still using the GKVoiceChat capabilities in their apps.

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...

Has anyone come across the issue that setting GKLocalPlayer.local.authenticateHandler breaks a RealityView's world tracking on iOS / iPadOS 18 beta 5? I'm in the process of upgrading my app to make use of the much appreciated RealityView unification, using RealityView not only on visionOS but now also on iOS and iPadOS. In my RealityView, I enable world tracking on iOS like this: content.camera = .worldTracking However, device position and orientation were ignored (the camera remained static) and there was no camera pass-through. Then I discovered that the issue disappeared when I remove the line GKLocalPlayer.local.authenticateHandler = { viewController, error in // ... some more code ... } So I filed FB14731139 and hope that it will be resolved before the release of iOS / iPadOS 18.
