I built the Gamekit Sample in apple/unityplugins for iOS and ran "_localPlayer = await GKLocalPlayer.Authenticate();" It worked fine up to the point where the GameCenter popup was displayed. However, the "OnRealtimeMatchmake()" and "OnToggleAccessPoint()" will result in the following error "MissingMethodException: Default constructor not found for type Apple.GameKit.Multiplayer.GKMatchRequest at System.RuntimeType.CreateInstanceMono" and "MissingMethodException: Default constructor not found for type Apple.GameKit.GKAccessPoint at System.RuntimeType.CreateInstanceMono" errors and does not work properly. Please tell me what is the problem here. The environment is as follows iPhone SE (iOS15.5), Unity2020.3.33f1, XCode13.4.1

the device orientation message maybe wrong when running unity app on ios 16, more information about this question is https://forum.unity.com/threads/game-may-start-with-incorrect-orientation.1410231/

Hello! Will developers be able to access frames from the passthrough cameras in Unity on the Apple Vision Pro? That is all!

Hi! I am trying to use the Apple Unity Plugins to add VoiceOver support to my game. I have built the plugins, and followed along with the video shown at https://developer.apple.com/videos/play/wwdc2022/10151/ However, I am seeing odd behaviour that I hope someone could help me with. For what it's worth, I am using Unity 2021.3.10f1 to build my game. I used the recommended version of Unity (2020.3.33f1) to build the plugins. Odd behaviour #1: I cannot work out what determines the order of AccessibilityNodes. If I have three GameObjects at the same level in the hierarchy, all marked with the trait button, using VoiceOver's single swipe right to go to each element in turn, seems to go to the last element first, then the first, then the second. At first I wondered if it was related to alphabetical order (GameObjects are called 'Music', 'SFX', 'Delete'), but renaming them to prefix numbers to the start of the names doesn't change the order. I have also tried removing the Label from the AccessibilityNode, but this did not help. Odd behaviour #1.5: The video says that Buttons don't need labels, and that if you use standard Unity UI controls, the label should be picked up automatically. I am not seeing this behaviour. I have a GameObject with a Button component, with a child GameObject with a TextMeshPro component. The label is not being picked up automatically. Odd behaviour #2: Once I have a button selected, I am unable to trigger it, with a VoiceOver 1-finger double tap. It just seems to repeat the label of the button. The GameObject I am trying to trigger just has a Button component, and the configuration looks the same as in the video. Does anyone have any successful experience using this plugin and could give me any insight? Thanks, Stephen

SPECIFIC ISSUE ENCOUNTERED I'm playing VR videos through my app using Metal graphics API with Cardboard XR Plugin for Unity. After the recent iOS 16 update (and Xcode 14 update too), videos in stereoscopic mode were flipped upside down and backwards. After trying to change sides manually in code, I only managed to show correct sides (it's not all upside down anymore), but when I turn the phone UP, the view is moving DOWN to the ground, and vice versa. Same issue for left-right phone moving. Also Unity-made popup question is shown on the wrong side (backside - shown in the video attachment) Here is the video of the issue for inverted (upside down flip) view: https://www.dropbox.com/s/wacnknu5wf4cif1/Everything%20upside%20down.mp4?dl=0 Here is the video of inverted moving: https://www.dropbox.com/s/7re3u1a5q81flfj/Inverted%20moving.mp4?dl=0 IMPORTANT: I did manage few times fixing it to work on local build, but when I build it for TestFlight, it is always inverted. WHAT I SUSPECT I found numerous other developers encountered this issue when they were using Metal. Back in the days when OpenGL ES 2 and 3 were still supported by Apple, it did fix the issue switching on one of those. But now since only Metal is supported with new Unity, there is no workaround, and also I would like to use Metal. DEVICE multiple iPhones running multiple iOS 16 versions has this issue. Specific OS version is 16.1 EXPECTED BEHAVIOR VR videos should show right side (not upside down image) and moving up should show upper part of the video, and vice versa. Same goes for left and right move. Currently everything is flipped, but not every time the same kind of flip. Sometimes in rare cases it's even shown correctly. VERSIONS USED What version of Google Cardboard are you using? Cardboard XR Plugin 1.18.1 What version of Unity are you using? 2022.1.13f1

Hi, I'm using the Unity plugins to access Game Center; there's a button in our UI that I want to use to open the Game Center dashboard on a particular leaderboard. The code for that is as follows, adapted from the GameKitSample.cs file: var leaderboard = leaderboards.First(l => l.BaseLeaderboardId == MY_LEADER_ID); var gameCenter = GKGameCenterViewController.Init(leaderboard, GKLeaderboard.PlayerScope.Global, GKLeaderboard.TimeScope.AllTime); await gameCenter.Present(); // game never returns from here Debug.Log("Back from Present()..."); gameCenter.Dispose(); I can play the game, hit the button, and view the Game Center dashboard, opened to the given leaderboard as expected. However, when I quit the dashboard (hitting the X in the top-right corner), the dashboard fades out, but the game is now unresponsive. I did notice that elsewhere in GameKitSample.cs, we have the following: var match = await GKMatchmakerViewController.Request(request); match.Delegate.DidFailWithError += OnRealtimeMatchDidFailWithError; Digging around for help with GKGameCenterViewController, I did notice that most solutions involve giving the viewcontroller a callback, but in the Unity plugin I see no Delegate listed for GKGameCenterViewController. Is this class missing the delegate, & therefore missing the callback that would dispose of the view?

public async void FetchItems() { try { var fetchItemsResponse = await GKLocalPlayer.Local.FetchItems(); } catch(GameKitException exception) { Debug.LogError(exception); } } App hangs when calling GKLocalPlayer.Local.FetchItems(); No exception is caught. Apple.Core and Apple.GameKit plugins have been included in our project Reproducible with https://github.com/apple/unityplugins Both Unity 2020 and Unity 2021 iOS and tvOS Xcode Version 13.4.1

Hello, I've added the Unity plugin for GameKit and it crashes on lunch, with this message. Library not loaded: @rpath/AppleCoreNative.framework/AppleCoreNative Referenced from: <22A243C2-0F80-36C5-8B0A-9C440F83A640>

Do I understand correctly that to use Unity (Universal Render Pipeline) for Vision Pro's fully immersive apps, we can normally use Unity's Shader Graph to make custom shaders; but for immersive mixed reality apps, we cannot use Shader Graph anymore, instead, we have to create shaders for Unity in Reality Composer? How does bringing Reality Composer's shader into Unity work? Is it simply working in Unity or will it require special adaptation for Unity? Are there some cases to avoid using Reality Composer, and use Unity's Shader Graph for immersive Vision apps? For instance, we may lose real-time lighting adaptation for virtual objects, but on the other hand, we will be able to use Shader Graph.

Hi, When I try to import the com.apple.unityplugin.core-1.0.3.tgz package into Unity from my Windows development machine I get lots of errors like : Library\PackageCache\com.apple.unityplugin.core@077039b365c9\Editor\AppleBuildStep.cs(48,136): error CS0246: The type or namespace name 'PlistDocument' could not be found (are you missing a using directive or an assembly reference?) Is it possible to get around this so I can develop on Windows? Thanks

Hi, I've tried multiple ways of solving this issue, including adding scripts, DISABLE Bitcode and non works. ERROR ITMS-90125: "The binary is invalid. The encryption info in the LC_ENCRYPTION_INFO load command is either missing or invalid, or the binary is already encrypted. This binary does not seem to have been built with Apple's linker." I am currently building a games with Unity, and trying to publish to test flight but no success at the moment. Non of the online solutions works on my side. Appreciate for your inputs, thanks in advance!

I recently integrated Unity IAP into my game and it works fine on android devices, but when I build a development build version on my iphone the purchase panel does not pop up, neither does the price get displayed. I recently agreed to the paid apps agreement, is that the reason why I am not able to see the purchase panel? Any kind of help would be appreciated.
