Dear Apple Developer Support, I hope this message finds you well. I am a game developer looking to integrate Game Center into our game. Before proceeding, I would like to understand the analytical capabilities available post-integration. Specifically, I am interested in tracking detailed metrics such as: The number of new player downloads driven by Game Center features (e.g., friend challenges, leaderboards, or achievements). Data on user engagement and conversions originating from Game Center interactions. I have explored App Store Connect’s App Analytics but would appreciate clarification on whether Game Center-specific data (e.g., referrals from challenges or social features) is available to measure growth and optimize our strategies. If such data is accessible, could you guide me on how to view it? If not, are there alternative methods or plans to incorporate this in the future? Thank you for your time and assistance. I look forward to your response. Best regards, Bella

Hi, I've got a Swift Framework with a bunch of Metal files. Currently users have to manually include a Metal Lib in their bundle provided separately, to use the Swift Package. First question; Is there a way to make a Metal Lib target in a Swift Package, and just include the .metal files? (without a binary asset) Second question; If not, Swift 5.3 has resource support, how would you recommend to bundle a Metal Lib in a Swift Package?

Guys, In my main application bundle, I have included a helper bundle in its Resources. When the helper requests Accessibility permission, the system modal window displays what the helper is requesting permission for. However, when the helper requests permission for Screen Recording, the system modal window displays that the main application bundle is requesting permission, which includes the helper. This issue seems to be specific to Ventura, as both requests are displayed on behalf of the helper in Monterey. I'm wondering if this is a known issue or limitation or if there is a way to make the permission request specifically from the helper.

, it is after update to Xcode 14.3: [default] CGSWindowShmemCreateWithPort failed on port 0

We've recently updated a view which displays photos via a CoreImage chain from a NSOpenGLView subclass to a NSView with a backing CAMetalLayer. Things are mostly working fine, but we occasionally hit a deadlock involving CALayer and CIMetalCommandQueue. I've made a spindump, it appears none of our code is involved in the locked threads. Despite this, I'm assuming the problem is ours 😅 I saw the mention in the CAMetalLayer documentation about releasing drawables with an @autoreleasepool in drawRect, we have done this and I can't find any places we're retaining a drawable outside drawRect. https://developer.apple.com/documentation/quartzcore/cametallayer?language=objc I am seeing this on macOS 15.0.1, M2 Max MacBookPro. We haven't seen it on macOS 14.x but it may be luck as we have not tested much on that OS. I don't know how to move forward debugging this, any help much appreciated! The two locking threads in the spindump are MainThread and CI::RenderCompletionQueue.

1.Open the DingTalk macOS application, start a meeting, and initiate screen sharing. 2.The DingTalk app calls the [SCShareableContent getShareableContentWithCompletionHandler:] API. 3.The API takes over 40+ seconds to return a response.

Hola. At this point, I'm at my wit's end because I've tried EVERYTHING just to be able to play a single game on my Mac, but the new update makes it impossible. So I'm just gonna ask for one game: I've been trying to play Stardew Valley, modded with SMAPI, for a week now. Despite playing the game with mods for almost 2 years, OS is refusing to open the game because SMAPI "contains malware". I tried reinstalling the mod, but no dice. It just automatically deletes the terminal and blocks the game from opening. You can imagine my frustration because the mod has been 100% safe for 2 years. No option to "Open Anyway" in Security Settings, either. I have no say in this. I've tried code signing it in Terminal (three times). Also no dice. Followed these two forums. https://www.reddit.com/r/StardewValley/comments/1h071jl/mac_deleted_stardew_modding_api_because_of_malware/ https://www.reddit.com/r/SMAPI/comments/1h0fgv9/solution_for_mac_malware_issue_with_smapi_417/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button NOTHING. Please tell me there's a way to override this??? Just let me install malware on my computer!😭

I have an app that uses GameController to read the inputs of a connected JoyCon. However, the controller also interacts with the OS. For example, when I press the Home button on the controller, it brings me to the home of my Vision Pro. Is it possible to disable this interaction while still being able to read the controller inputs inside my app?

Dear Apple, there is still no support for WebGPU via WebView. Do you have a roadmap on when you plan to support it? That would be very helpful to release our new game.

I use unity 2020.3.48f1 to develop a game; trying to implement Apple Services integration I use Apple unity plugins(https://github.com/apple/unityplugins) Using latest version of unity plugins I getting error in Unity project after plugin import It say "Not allowed platform VisionOS" When I tryed to use older version of the plugins I getting error on runtime when calling "var fetchItemsResponse = await GKLocalPlayer.Local.FetchItems();" in line 42 it drop EXC_BAD_ACCESS(code=257, address=0x0000...) error I tryed to use different commits from official repositorys and even custom branches of apple unity plugins like (https://github.com/muZZkat/unityplugins/tree/muzzkat/fix-fetch-items) but it did not help There is whole my script which trying to use apple unuity plugins using System.Threading.Tasks; using UnityEngine; using System.Collections; using System; using Apple.GameKit; using UnityEngine.UI; public class TheScript : MonoBehaviour { [SerializeField] InputField otp; string Signature; string TeamPlayerID; string Salt; string PublicKeyUrl; string Timestamp; void Start() { StartCoroutine(Call()); } private IEnumerator Call() { yield return new WaitForSeconds(5); Login(); } public async Task Login() { otp.text += $"Loginig...

For an app of mine I use CGSetDisplayTransferByTable to adjust the gamma table of the device. Since macOS Tahoe, these modifications are silently ignored. The display's actual gamma curve remains unchanged despite the API reporting successful completion. I've filed a FB for it a few weeks ago, and would love to figure out what could be causing this.

I've been playing with the new GameSave API and cannot get it to work. I followed the 3-step instructions from the Developer video. Step 2, "Next, login to your Apple developer account and include this entitlement in the provisioning profile for your game." seems to be unnecessary, as Xcode set this for you when you do step 1 "First add the iCloud entitlement to your game." Running the app on my device and tapping "Load" starts the sync, then fails with the error "Couldn’t communicate with a helper application." I have no idea how to troubleshoot this. Every other time I've used CloudKit it has Just Worked™. Halp‽ Here is my example app: import Foundation import SwiftUI import GameSave @main struct GameSaveTestApp: App { var body: some Scene { WindowGroup { GameView() } } } struct GameView: View { @State private var loader = GameLoader() var body: some View { List { Button("Load") { loader.load() } Button("Finish sync") { Task { try? await loader.finish() } } } } } @Observable class GameLoader { var directory: GameSaveSyncedDirectory? func stateChanged() { let newState = withObservationTracking { directory?.state } onChange: { Task { @MainActor [weak self] in self?.stateChanged() } } print("State changed to \(newState?.description ?? "nil")") switch newState { case .error(let error): print("ERROR: \(error.localizedDescription)") default: _ = 0 // NOOP } } func load() { print("Opening gamesave directory") directory = GameSaveSyncedDirectory.openDirectory() stateChanged() } func finish() async throws { print("finishing syncing") await directory?.finishSyncing() } }

When previewing the recording of gameplay the buttons to exit or save are unclickable behind the top bar clock and Wi-Fi/5G status bar. Which means that you have to quit the game in order to continue. Tested on multiple devices. Does anyone have a solution to this? At the moment we have disabled it altogether for iOS 26 users.

I'm an iOS developer, and I've been testing our app in iOS 18.0 Beta. I noticed that there's a problem with the font rendering, and after troubleshooting, I've found out that it's caused by the removal of the PingFang.ttc font in 18.0. I would like to ask the reason for removing this font file and which font should be used to display Chinese in the future? My test device is an iPhone 11 Pro and the system version is iOS 18.0 (22A5297). I have also tested Beta 1 and it has the same issue. In previous versions of the system, the PingFang font is located in this directory /System/Library/Fonts/LanguageSupport/PingFang.ttc. But in iOS 18.0, the font file in this directory has become Kohinoor.ttc, and I've tested that this font can't display Chinese either. I traversed the following system font directories and could not find the PingFang.ttc font file. /System/Library/Fonts/AppFonts /System/Library/Fonts/Core /System/Library/Fonts/CoreAddition /System/Library/Fonts/CoreUI /System/Library/Fonts/LanguageSupport /System/Library/Fonts/UnicodeSupport /System/Library/Fonts/Watch Looking for answers, thanks for the help!

I am trying to install the game-porting-toolkit using brew -v install apple/apple/game-porting-toolkit but this fails each time because of a dependency on a deprecated openssl version: Fetching dependencies for apple/apple/game-porting-toolkit: cmake, ninja, apple/apple/game-porting-toolkit-compiler, openssl1.1 ... ... Error: openssl@1.1 has been disabled because it is not supported upstream! It was disabled on 2024-10-24. Is there a way to override this dependency or use a newer version of openssl for the check?

After updating to MacOS 26.1 I encountered an issue that Roblox tends to freeze quite often for 10 - 60 seconds at most, this is really annoying that it is doing this as i play the game a lot. My theory is that it is like a driver issue with metal or something, I have reinstalled MacOS, reinstalled the game and lowed the performance manually but nothing is working. Wondering if you could help, when it will be fixed and if others are having the same issue. Many thanks, William.

I searched the Metal Shading Language Specification Version 3.0 document, however I cannot see any function for inverting a matrix. Is there really no function in Metal for inverting a matrix? I often need to this in linear equations and have so far resorted to writing the necessary function each time, most of the time just copy-and-pasting code. inverse exists in SIMD and GLSL, so why not in Metal? It seems so unexpected that this function does not exist that I am almost certain I have just overlooked something obvious. I even tried 1 / M, to no avail.

Hello, I've been tinkering with PortalComponent on visionOS a bit but noticed that the content of the WorldComponent is always clipped to the mesh geometry of whatever entities have the PortalComponent applied. Now I'm wondering if there is any way or trick to allow contents of the portal to peek out – similar to the Encounter Dinosaurs experience on Vision Pro (I assume it also uses PortalComponent?). I saw that PortalComponent has a clippingPlane property (https://developer.apple.com/documentation/realitykit/portalcomponent/clippingplane-swift.property). But so far I haven't been able to achieve a perceptible visual difference with it. If possible I would like to avoid hacky tricks using duplicate meshes or similar to achieve this. Thanks for any hints!

We are seeing crashes in Xcode organizer. So far we are not able to reproduce them locally. They affect multiple app releases (some older, built with Xcode 15.x and newer built with Xcode 16.0). They only affect iOS 18.5. Is there anything that changed in latest iOS? It's hard to tell what exactly is causing this crash because setting symbolic breakpoint on CA::Render::Image::new_image(unsigned int, unsigned int, unsigned int, unsigned int, CGColorSpace*, void const*, unsigned long const*, void (*)(void const*, void*), void*) triggers this breakpoint all the time, but not necessarily with exactly the previous stack frames matching the crash report. Is it a known issue? crash.crash Thank you.
