I need clarification on the GKLocalPlayer.local.isMultiplayerGamingRestricted behavior which check's user's device capability (whether it is set up to allow or disallow multiplayer) I am referring to this from Apple documentation at : https://developer.apple.com/documentation/gamekit/authenticating_a_player if GKLocalPlayer.local.isMultiplayerGamingRestricted { // Disable multiplayer game features. } The issue is that this is a boolean (true/false value ) However I have noticed that iOS ( latest version and preceding versions) allow people to have the following options: ( you can set these under screen time -> content restrictions -> Multiplayer games ) Disallow all multiplayer games - presumably your API returns a false for this. Allow multiplayer with friends only -???? what does GKLocalPlayer.local.isMultiplayerGamingRestricted return here?? if True, how is the Friends only restriction handled? Are we supposed to do something to force it? Note: So far I am relying on Apple's Game Center native experience and have not added wrappers to do additional filtering etc. I hope that I shall be able to keep doing so. Allow all multiplayer games - presumably your API returns a false for this. You can see how there are three choices but this is modeled as a boolean. Choice number 2. is not addressed. Has anyone come across this? Note: This is very different from checking for underage users. No matter what I do, in my post above, it won't set the correct numbers for numbered bullet -points. I call them 1, 2, 3 it posts 1,1,2 or 1.,2,1 etc. ( side nit ) Apologies if this isn't as readable as it should be.

Hi, I am a musician and I tried the vision pro a few days ago. I have ideas to launch the related app on Vision Pro. I would like to find a developer who can help me build up the app :) Thank you all!

I've installed the GPTK before, but it pops up with some problems so I want to reinstall it again. So I deleted home brew and redownload all the materials I needed. But when it comes to install the game-porting-toolkit formula, I can't download it, did anyone have the same problem with me? jimmy@Jimmymbp14 ~ % brew -v install apple/apple/game-porting-toolkit Error: Formulae found in multiple taps: * apple/apple/game-porting-toolkit-compiler * gcenx/apple/game-porting-toolkit-compiler Please use the fully-qualified name (e.g. apple/apple/game-porting-toolkit-compiler) to refer to a specific formula. jimmy@Jimmymbp14 ~ %

I am currently developing an USB HID Device, specifically a type of Joystick. However it seems that any attempt of getting a joystick to work on Mac do not work. My prototype works perfectly on Windows, being recognised as such and receiving all data. On MacOS, the Joystick is not recognised as a Joystick though, and the OS does not seem to receiver any Input from it whatsoever. I have translated my code to use both Mouse and Keyboard, both work perfectly. I have also tried to have the Joystick identify as a Gamepad, but again, it works on Windows and is not recognised on Mac (is not recognised as a Gamepad). Are there any specific restrictions to HID devices on MacOS? Apple developer only seems to describe specifics from a software standpoint, not from the standpoint of someone developing hardware. And even then it only seems to describe very specific HID devices, such as mouse, keyboard or a stylus. Please also keep in mind that I don't have much experience developing MacOS applications.

Hi all, I have a macbook air 2022 with the M2 chip inside. I am trying to use a wired xbox 360 controller to play games on steam. However, whenever I try to plug it it, the light shines green for a little bit and then turns off. I checked in my usb device tree through the system report and it says that there is a controller plugged in. The controller doesn't work in the game either, are there any fixes? I am also on macOS Monterey version 12.4

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.

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 tried twice to install homebrew and I got a error message twice: Error: apple/apple/game-porting-toolkit 1.1 did not build Logs: /Users/omarzunun/Library/Logs/Homebrew/game-porting-toolkit/00.options.out /Users/omarzunun/Library/Logs/Homebrew/game-porting-toolkit/01.configure /Users/omarzunun/Library/Logs/Homebrew/game-porting-toolkit/01.configure.cc /Users/omarzunun/Library/Logs/Homebrew/game-porting-toolkit/02.make /Users/omarzunun/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

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"

We are using apple unity plugin (gamekit) to authorized player using game center account. To get player the info we run a task from the plugin, var fetchItemsResponse = await GKLocalPlayer.Local.FetchItems(); But when this code run, there is an error on the xcode application on mac. The error is the following, Thread 1: EXC_BAD_ACCESS (code=257, address=0x2)

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?

Hi everyone, I'm trying to implement matchmaking in visionOS using GameKit and GameCenter. I'm following the example project that been shared but I get an error. Error: The requested operation could not be completed because you are not signed in to iCloud.. I'm getting this error as a result of matchmaking. I'm already logged in to iCloud in Vision Pro Simulator. I've tried to switch off-on every related settings but didn't work. I'm using latest Xcode Dev Beta and visionOS Beta v6. Would you mind share me any workaround? Regards, Melih

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?
