Hello, I am building an app that requires players joined to an online game session and to have a video chat with both of their front cameras turned on. I currently know that GameKit supports the voice chat option but could not find any source for video chat. Is it possible set up a video chat on an online game session?. What libraries can I use that have support in implementing the video chat (AVFoundation) ? Your assistance is greatly appreciated.

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.

I am on a MacBook Pro 2023. 16inch, 16gb ram, 1tb drive. I am on the latest MacOs (Sonoma 14.3.1) and using the steps from the Apple Gaming Wiki to download the Game Porting Toolkit. I have met all the requirements. I tried using the automated installer, didn't work. I tried doing homebrew, and it worked all up until I got to the step where I had to run the command to download Apple tap: brew tap apple/apple http://github.com/apple/homebrew-apple I get this error: Logs: /Users/MYNAME/Library/Logs/Homebrew/game-porting-toolkit/00.options.out /Users/MYNAME/Library/Logs/Homebrew/game-porting-toolkit/01.configure /Users/MYNAME/Library/Logs/Homebrew/game-porting-toolkit/01.configure.cc /Users/MYNAME/Library/Logs/Homebrew/game-porting-toolkit/02.make /Users/MYNAME/Library/Logs/Homebrew/game-porting-toolkit/wine64-build If reporting this issue please do so to (not Homebrew/brew or Homebrew/homebrew-core): apple/apple

Hi Apple and Swift friends. I'm not really a fluent Swift programmer (or any language) just knowledgable, I just a vague logic of what's going on. This is a gamepad controller remapper similar to DS4Windows on the PC and DSX on Steam gaming. On macOS Sonoma, it successfully compiled and connected the amazing Sony Playstation DualSense but because it has 33 yellow warning, the Setting doesn't show. It says something about outdated something and needs to be replaced by a newer framework.network. It also says it can't use self: It should look like these: What could be the syntax changes that won't produce the 30+ yellow warnings? The file can be had here: [https://github.com/marcowindt/ds4macos) God bless.

I have my Xbox Controller plugged into my Macbook, but my controller won't stay on (no batteries are needed for this controller, and the plug I am using works). Also in system settings when I scroll to Xbox Controllers it says no devices found. How do I fix this?

I'm trying to establish a connection between two devices using mobile network. The config in both devices are ok allowing use mobile data for the app. I'm able to connect and start the game with WIFI networ `// Initiate matchmaking - (void)initiateMatchmakingWithViewController:(UIViewController*)rustViewController { dispatch_async(dispatch_get_main_queue(), ^{ if (![GKLocalPlayer localPlayer].isAuthenticated) { NSLog(@"Player is not authenticated."); return; } NSLog(@"Preparing MatchMaker"); GKMatchRequest *request = [[GKMatchRequest alloc] init]; request.minPlayers = 2; request.maxPlayers = 2; GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithMatchRequest:request]; mmvc.matchmakerDelegate = self; // Use the passed view controller to present the matchmaking UI [rustViewController presentViewController:mmvc animated:YES completion:nil]; NSLog(@"MatchMaker running...."); // Store the rustViewController for later, to revert back to it originalViewController = rustViewController; }); } // GKMatchmakerViewControllerDelegate methods - (void)matchmakerViewControllerWasCancelled:(GKMatchmakerViewController *)viewController { [originalViewController dismissViewControllerAnimated:YES completion:nil]; NSLog(@"Matchmaking was cancelled."); } - (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFailWithError:(NSError *)error { [originalViewController dismissViewControllerAnimated:YES completion:nil]; NSLog(@"Matchmaking failed with error: %@", error.localizedDescription); } - (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match { [originalViewController dismissViewControllerAnimated:YES completion:nil]; self.currentMatch = match; match.delegate = self; NSLog(@"Match found."); // Fetch details for each player in the match NSMutableArray<NSString *> *playerIDs = [NSMutableArray array]; for (GKPlayer *player in match.players) { [playerIDs addObject:player.playerID]; } [GKPlayer loadPlayersForIdentifiers:playerIDs withCompletionHandler:^(NSArray<GKPlayer *> *players, NSError *error) { if (error) { NSLog(@"Error retrieving player details: %@", error.localizedDescription); return; } for (GKPlayer *player in players) { if (![player.playerID isEqualToString:GKLocalPlayer.localPlayer.playerID]) { [self loadAndStoreAvatarForRemotePlayer:player]; } } }]; }` I can see how both clients are in state "connecting" but the log "Match found." it's never set. I also can see this log "[Match] syncPlayers failed to loadPlayersForLegacyIdentifiers"

I'm working in a game where I integrate matchmaker and it's working fine when I try with two devices under same wifi network, but in the moment I use 5g mobile network and I do the matchmaker, I can still see each other but the game did not start and I see error sending data to the remote player. The game is not yet published and I'm using TestFlight for the clients.

I'm trying to implement multiplayer invitation from game center for macos, ios, tvos following this https://developer.apple.com/documentation/gamekit/finding_multiple_players_for_a_game?language=objc Implementation works for tvos and ios, I can invite my friends, Start Game and continue sending data. But macos still doesn't work at all. I tried using build that works on iOS to invite macos player, but my mac cannot even receive the invitation notification from game center (game is installed already on mac). While from mac, my invitation process is stuck here until it's failed Is there any specific setting on macos to enable game center invitation?

In our multiplayer game prototype, we experience a ping of 300 ms (at best) when using Game Center and GKMatch to send data between players, over the GKMatch.SendDataMode.unreliable channel. This latency is not suitable for a real-time game. When we tested alternative services like Unity's Relay under identical conditions (location, devices, and Wi-Fi), we achieved a ping of 120 ms. Is a ping value of 300 ms typical when using Game Center? I can think of possible reasons in case it's not typical, but I can't be sure: Is there a different behavior (servers relaying peer-to-peer connections) when the game is not yet released on the store? We're in Europe, maybe this is normal in Europe and better in US?

I'm working in a game that it was working perfectly with Game Center (remote game with 1 remote player), but since last Sunday I'm having errors when I try to start a remote game. I have 2 errors, one says FAILED when I invite a friend to play. In this case, the other device never gets the notification. The other error sent the notification, but when I tap on it (on the other device), it fails saying that it couldn't communicate with the server). The main device it says "INVITED" but it doesn't say anything else. I haven't found anyone else having the same issue, so I wonder if it's my fault, although I haven't change that part of the code since the last time I tested it. Is it someone else here having similar problems? or knows what should I review? thank you all, and have a great year!

I am using GCSystemGestureStateDisabled to suppress home button being capture by gesture recognizer so the system menu is not triggered while my app is using the gamepad. It was working well on macOS 14.1 but stop working after I migrated to 14.2. boundToSystemGesture is still showing "Yes" after button.preferredSystemGestureState = GCSystemGestureStateDisabled is assigned. Is it possible some change was introduced on 14.2 causing the issue?

How to get current player score and position? Thanks!

I'm trying to display the native GameCenter interface from Unity (I've already tried Bounded and Unbouded Volume Mode, that is, with and without Full Immersive Mode) but I can't display this interface.

Hello, I'm working on a game application and I've been wondering about how I can separate the GameKit Leaderboards I'm using for testing purpose and the ones that would be "live" (i.e: only for the users) I've been point out that I can attach leaderboards to an app version but it makes me wondering about compatibility. I'm working on the application in version 1.1. My users are using the application in version 1.0 (with their leaderboards). Then I'm releasing a version 1.2. It would means I need to attach all the leaderboards from version 1.0 to version 1.2 and to me it's very tedious. What would be the best practice with using leaderboards on multiple environments? Thanks

I tried to update my current game controller code to the new iOS 17.0 GCControllerLiveInput. But the Touchpads of the PS4 and PS5 controllers are not listed as elements of the GCControllerLiveInput. Were they moved somewhere else? They are not listed as a GCMouse, and I didn't find anything about this in the documentation or header files either...
