I'm distributing a Unity-built game on the Mac App Store and I've been rejected twice under Guideline 4 (Design) with the same wording: "We still noticed that the app presents a window that does not contain the necessary title bar buttons and includes an interface window but is missing the required App Menu and Dock Icon or Menu Bar Extra." I'd like to hear from anyone who has hit this with a Unity (or otherwise non-native) macOS app and got it resolved. What I'm seeing: When the game runs, the macOS menu bar is displayed, but it only shows the app name and a single "Window" menu. The standard menus Apple expects (App menu with About/Quit, Edit, Window, Help) are not there. Unity does not populate the native macOS menu bar on its own, and there's no Player Setting that generates these menus. What I've already tried: Switched the app from borderless window to a standard windowed mode, so the window has its title bar and close/minimize/zoom buttons. Confirmed the Dock icon appears with the running indicator in standard windowed mode. Verified there is no LSUIElement key forcing the app into accessory mode in Info.plist. Despite this, the rejection came back identical. My questions: For those who passed review, did you populate the full native menu bar (App / Edit / Window / Help), or did Apple accept the app another way? Is a complete standard menu bar strictly required, or does shipping the app in fullscreen — where macOS hides the menu bar by design, as with most Mac games — satisfy the reviewer on this point? For the "title bar buttons" and "Dock icon" part of the rejection specifically: what exactly does the reviewer expect to see, and does fullscreen change how they evaluate it? If you resolved this, did you mention the change in the App Review notes, and did that help? Any concrete experience — especially with games that launch fullscreen — would be very helpful. Thanks.

We are investigating a Game Center authentication issue that appears to affect some devices consistently. Symptoms: Game Center authentication initiated from our app does not complete. The GKLocalPlayer authentication flow does not recover during the session. The issue is not limited to our app: on affected devices, the Game Center section in the iOS/iPadOS Settings app also fails to load. The Games app also fails to load. After a device restart, Game Center may work once, but then becomes unavailable again and further authentication attempts fail. We have reproduced this on iPadOS 26.5. In addition, our analytics show an unusually high percentage of unfinished Game Center authentication attempts on this OS version. We have also received individual reports from users on other devices/OS versions. Given that the Game Center Settings screen and the Games app are also affected, this appears to be a system-level Game Center availability problem rather than an issue isolated to our application. There is a description of a similar problem https://developer.apple.com/forums/thread/787749 But it belongs to beta testing and is marked as fixed.

Even when making a completely fresh Unity project, if I include ARKit and upload it to testflight, when I open it on my ipad it says 'Couldn't Load App'. If I don't include testflight the app opens fine. If I build the app directly to my ipad the app works fine. It opens if I set ARKit to 'optional' but then the AR doesn't work. I have included a camera and location usage description so it's not that. Really not sure what's going on, any help would be massively appreciated!

This is using: **Unity 6000.2.7f - latest ARKit etc Xcode 26.1 ** This is going to iPad/iPhone/iOS and I have succesfully built to the iPad before, but updates to the software seem to have added these errors in.

I am using the latest version of the Game Center plugin for Unity and have noticed that my game will crash on launch when trying to authenticate. I've tried this in an empty project with just the plugin and it still crashes with this exception.

I'm having issues getting a well built package from the Apple Unity Plug-in project. When building the my game project in Unity the following error is printed to the console: Apple.Core.AppleNativeLibraryUtility] Cannot locate a Debug or Release Apple.Core native library for iOS. Please ensure that the build invocation (build.py, xcodebuild, or Xcode) compiled cleanly and that the build was configured to support Debug on iOS. As far as I can tell the build did compile cleanly, but I might be missing something. If anyone can see what I'm doing wrong or has any insight it would be greatly appreciated. Setup is the following: macOS Tahoe 26 Beta Xcode-beta Version 26.0 beta 3 (17A5276g) Unity Plug-in branch: 2025-beta1 Unity game project version: 2022.3.60f M1 Macbook Pro The built packages have been imported into the game project through the Unity Package Manager using the tarball option pointing to the built packages from the Unity Plug-in project. The Unity Plug-in project has been built using the build.py file with the following: python3 build.py -m iOS iPhoneSimulator -p Core GameKit CoreHaptics GameController -k all The output is available in the attached file. build-output.txt Here's an image of the NativeLibraries~ folder inside the built Apple.Core package.

Hi, I am trying to load files from the Apple Vision Pro's storage into a Unity App (using Apple visionOS XR Plugin and not PolySpatial package). So far, I've tried using UnitySimpleFileBrowser and UnityStandaloneFileBrowser (both aren't made for the Vision Pro and don't work there), and then implemented my own naive file browser that at least allows me to view directories (that I can see from the App Sandbox). This is of course very limited: Gray folders can't be accessed, the only 3 available ones don't contain anything where a user would put files through the "Files" app. I know that an app can request access to these "Files & Folders": So my question is: Is there a way to request this access for a Unity-built app at the moment? If yes, what do I need to do? I've looked into the generated Xcode project's "Capabilities", but did not find anything related to file access. Any help is appreciated!

I just upgraded my macOS, Xcode and Simulator all to the newest beta version 26. Then I found two issues when building my app with Xcode 26 and running it on simulator 26. The game center access point no longer shows up in the app. This is how it's configured in the past. And it still works on simulator 18.4 func authenticatePlayer() { GKAccessPoint.shared.location = .topTrailing self.localPlayer.authenticateHandler = { viewController, error in if let viewController = viewController { // can present Game Center login screen } else if self.localPlayer.isAuthenticated { // game can be started } else { // user didn't log in, continue the game without game center } } } After game ended, the leaderboard won't load. This is how it's implemented in the past. It's still working in simulator 18.4 struct GameCenterView: UIViewControllerRepresentable { @Environment(\.presentationMode) var presentationMode ... func makeUIViewController(context: Context) -> GKGameCenterViewController { let viewController = GKGameCenterViewController( leaderboardID: getLeaderBoardID(with: leaderBoardGameMode), playerScope: .global, timeScope: .allTime ) viewController.gameCenterDelegate = context.coordinator return viewController } func updateUIViewController(_ uiViewController: GKGameCenterViewController, context: Context) {} func makeCoordinator() -> Coordinator { Coordinator(self) } class Coordinator: NSObject, GKGameCenterControllerDelegate { let parent: GameCenterView init(_ parent: GameCenterView) { self.parent = parent } func gameCenterViewControllerDidFinish(_ gameCenterViewController: GKGameCenterViewController) { parent.presentationMode.wrappedValue.dismiss() } } }

I’m testing Game Activities in my Unity project with the new Apple.GameKit 2025-beta1 plugin. When I go into Xcode- Debug → GameKit → Manage Game Progress → Leaderboards → and click the generated link: If my app is already running in the background, the link opens the app and my handler (Apple.GameKit.GKGameActivity.WantsToPlay += OnWantsToPlay;) fires as expected. I can read the activity and route the player to the right level. If the app is completely closed, clicking the same link launches the app, but my OnWantsToPlay listener is never invoked. The app just boots normally and the activity intent seems lost. I’ve tried to subscribe as early as possible (in Awake() of my bootstrap scene, also tested with RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]). Nothing works. Also, “Get Started with Game Center” video only demonstrates activation when the app already running, not a cold start from a Game Activity link. What am I missing? Environment Device/OS: iPhone on iOS 26.0 beta (Game Center sandbox) Xcode: 26.0 beta 6 Unity: 2022.3.21 Apple GameKit Unity plugin: 2025-beta1 (GameKit package) Signing: Game Center capability enabled; using development provisioning profile GameKit resources: GameCenterResources.gamekit in project (Target: Unity-iPhone), appears under Build Phases → Copy Bundle Resources

Hi, I'm trying to add game center challenges and activities to an already live game, but they are not appearing in game for testing, GameCenter, or the Games app. I know the game is setup with GameKit entitlements since this is a live game and it has working leaderboards and achievements. I've updated to Tahoe beta 8, added a challenge and activity on app store connect, added that to a new distribution and added that distribution to 'Add for Review' I'm using Unity and the Apple Unity plugin Not sure what other steps I'm missing Thanks

Hello, We are experiencing an issue with apparent lag or latency when interacting with objects in Unity using the XR Interaction Toolkit. Even when interactables are configured with the Movement Type set to Instantaneous, objects exhibit a noticeable delay when following hand movement. This issue is particularly apparent when the hand moves at higher speeds. We would like to know: is any additional configuration required, or is there something else we need to do to resolve this? Thank you very much for your assistance.

I’m running into unexpected problems with the Unity GameKit plugin setup with the new Activities. I didn’t see anyone else mentioning these issues, so my guess is that it’s a problem with my setup. The authentication (GKLocalPlayer.Authenticate()) works as expected, but any call to the new GameActivity functionality (e.g. GKGameActivityDefinition.LoadGameActivityDefinitions() or GKGameActivity.WantsToPlay) gives me an exception with a 'UnsupportedOperationForOSVersion' reason despite it running on an iOS 18.6.1 device. I’m using a completely empty Unity 2022.3.62f1 project that only contains the official authentication example, followed by an event handler for activities from another example and the Unity core and gamekit plugins. The setup: macOS 15.6 Xcode 26 beta 6 (also tried with 5) Physical iPhone device running iOS 18.6.1 Unity 2022.3.62f1, which satisfies the requirements Unity plugin, Xcode setup, and build steps: I Followed the official beta branch build steps for Unity plugins with python3 build.py -m iOS iPhoneSimulator macOS -p Core GameKit which ran through after a slight modification for the macOS target that somehow contained an unknown team reference for the GameKitWrapper project, which I changed to not reference a team and use ‘sign to run locally’, as was the case for the other packages. As far as I understood the macOS version is not strictly necessary either way just for running it on a local iOS device(?) I Imported these as tarball packages into the empty Unity 2022.3.62f1 project as per the official instructions, which seems to work as expected Added a single script with the mentioned example code added in a MonoBehavior.Start Building in Unity works as expected as well, creating the Xcode project The Unity-iPhone target has the GameKit framework linked (’do not embed’) and the GameCenter capability was added automatically as expected The GameKit framework seems to not be added to the UnityFramework target, but I don’t think this is necessary? Quickly testing this with the GameKit framework added there as well didn’t make a difference The linked GameKit framework is indeed the expected Xcode 26 beta version I can then build and run this on the physical iPhone iOS 18.6.1 device, where I get an ‘UnsupportedOperationForOSVersion’ as soon as I try to subscribe to deeplinking events (GKGameActivity.WantsToPlay) or use other GameKit Activity functionality from the official examples: // log showing that it's actually running on iOS 18.6: [Apple.Core Plug-In Runtime] Availability Runtime Environment: iOS 18.6 Apple.Core.Availability:OnApplicationStart() // and the exception I get: GameKitException: Code=-7 Domain=GKErrorDomain Description=The operation couldn’t be completed. (GKErrorDomain error -7.) (UnsupportedOperationForOSVersion) at Apple.GameKit.DefaultNSErrorHandler.ThrowNSError (System.IntPtr nsErrorPtr) [0x00000] in <00000000000000000000000000000000>:0 Rethrow as TypeInitializationException: The type initializer for 'Apple.GameKit.GKGameActivity' threw an exception. I unfortunately didn’t find any clues as to why this happens and how to resolve it on this forum or otherwise. Changing the minimum iOS version - up to 18.6 from the previously used (Unity export default) 12.0 for any and all targets - did not yield a different result I'd rather not update the phone to use the iOS 26 beta, though as far as I understood this is not necessary Any pointers to what I might be missing or doing wrong are greatly appreciated! Thank you very much in advance!

When running my game in the Unity Editor on Windows platform I get an error: DllNotFoundException: GameKitWrapper assembly:<unknown assembly> type:<unknown type> member:(null) Apple.GameKit.DefaultNSErrorHandler.Init () (at ./Library/PackageCache/com.apple.unityplugin.gamekit@0abcad546f73/Source/DefaultHandlers.cs:35) This is because GameKitWrapper dynamically linked library is not available under Windows platform. Besides, "Apple Build Settings" are declared under UNITY_EDITOR_OSX and also not available under Windows platform. Does anyone managed to solve this?

Hello, As titled, my team is trying to find a way to add unity projects to our current developments. We have checked several posts and tutorials, but find they are all about porting to a brand new project. Without modifying too much on our current swift codes, we wonder if we can add Unity part as a WindowGroup/ImmersiveSpace like the following? :) struct TestVisionUnityApp: App { var body: some Scene { // from default template WindowGroup { ContentView() .... } // @TODO WindowGroup {...} } }

I need help. Looking for devs who’ve integrated Unity into a native iOS app (Swift/SwiftUI) SwiftUI vs Flutter for Embedding Unity in an iOS App? I’m planning an iOS-first app where users interact with a real-time 3D custom avatar with 52 blendshapes powered by Unity, using SALSA LipSync + Emoter for facial animation. The avatar will respond to voice using Whisper → GPT-4 → ElevenLabs. My plan is to embed Unity only for the avatar screen, and build the rest of the app (chat, voice input, onboarding, etc.) natively? Here’s the decision I’m stuck on: Should I stick with SwiftUI, since it gives full access to iOS-native features like ARKit, audio routing, and StoreKit? I only plan to develop for iOS. Has anyone here integrated Unity with Flutter for mobile app successfully? Any pitfalls or major limitations I should know about before going that route? I haven’t started development yet — just want to make sure I choose the right foundation for performance, flexibility, and long-term growth. Any experience would be hugely appreciated!

There is a bug in Unity Plugins: Corehaptics.AssetPickerDrawer throws exceptions and draws incorrectly when fieldInfo or assetType is null (FB17305973). I fixed it and created a pull request: https://github.com/apple/unityplugins/pull/47 It has been months and this bug is really annoying.

Hello Everyone I am new here, I am testing game center integration and using a development build of my IOS game. I have set up a couple of achievements in app store connect, but when I trigger them in the game then they do not unlock or show up. Okay so i am signed into the game center with a sandbox account on a test advice. Is there anything else I need to configure, or do achievements usually only work after the game is released?. I will appreciate any guidance… Thanks in Advance!!!

We are experiencing an issue with our iOS TestFlight builds where in-app purchase (IAP) products are not being retrieved as expected. We are using Unity IAP to handle our purchases, and despite having all the products correctly configured and approved in App Store Connect, we consistently receive errors such as: UnityIAP: Received 0 products Unavailable product [product_id] We have thoroughly verified that: The product identifiers are correctly configured in App Store Connect. The bundle ID mappings are correctly set on both Unity and our backend. The same setup works on the live App Store build, where purchases are fetched and validated correctly for the same set of In App products. Sandbox test accounts are being used during TestFlight testing. This issue only started appearing recently and affects the TestFlight builds only. Note: My App ID and Product ID are correct, the IAP is live on the App Store, and the product is recognized in sandbox. Looking forward to your support on this matter.
