In my turn-based game, I receive GKListener event receivedTurnEventForMatch and decode the match.matchData. On occasion, the matchData is clearly stale and is from the previous turn. If I call the MatchMaker ViewController up and select that same match, the data is not stale, so it's not a matter of not calling endTurn. I have tried both loadMatchWithID and loadMatchesWithCompletionHandler after receiving the receivedTurnEventForMatch, but the data is still stale. Advice?

Updated my app to include turn-based matches. Beta testing through FlightTest and all was well between iOS 18.x and 26.2 devices. One beta tester upgraded to 26.2 during beta testing and now when the MatchMaker VC is opened, it does not show existing matches. Worse, he can create new matches and play his turn, but the new match won't even show up in MMVC, even after opponent takes turn. My app has been reviewed and is ready for release, but I'd like to know how to solve this before I release. He has tried re-installing the app, including an updated FlightTest version that is the same as the about-to-be-released reviewed version.

I'm updating an existing distributed game to add turn-based matches. When the Matchmaker ViewController Info Button next to a game is pressed, the results vary: iOS 15.x - Button under avatar says "Accept Invite" or "View Game" (depending on if invite has already been accepted) iOS 18.x - Button always says "App Store" - I assume that means it would lead one to the App store to install the game. Both devices (iPad 15.x and iPhone 18.x) have the same version of the game installed. The results are the same when running in the simulator. When the game is released, I assume this button will work properly, no?

Turn-based games: 2 players When an opponent declines a game in the Game Center MatchMaker VC, that player sees that they quit, but no message is sent to the listener about that fact. For the person who started the match, their MMVC shows it's their turn again. Why doesn't Game Center end the match?

I have used the Push Notifications Console and verify that the test notification reaches my device (it says "not necessarily the app"). However, GameCenter notifications are not reaching the app. When one device passes the turn, the turn is successfully passed as seen in the Matchmaker VC. However, the app does not get the turn pass notification whether or not it is running. No banner appears if the app is not running (but it does when using the Push Notifications Console). Please advise.

I have two devices (iPod, iPhone), each using a different Apple ID. I have an existing game to which I'm adding TBM. When the iPod invites the iPhone, it sends an iMessage invite to the iPhone; when I click on that message, I get "Retrieving", then Game Center in Settings is opened, not my App (same version installed on both devices). I start my App on the iPhone and that match is not shown in the Matchmaker View Controller. When I send an invite from the iPhone to the iPod and I click on the iMessage invite, the app starts but the match isn't listed in the MatchMaker ViewController on the iPod (but is on the iPhone). In addition, when I click on the info circle on the iPhone, it who's the two players and "App Store" under the Game Center name. However, When I do the same on the iPod, it has a "Play your turn" there. Any ideas?

Under threat of future crashes, I'm adding support of UIScene to my existing apps. Each app has two storyboards - Main for iPads and Main_iphone for iPhones. Pre-UIScene, all looks great. With the addition of the Application Scene Manifest, the iPhone versions of the app are using the Main storyboard instead of the Main_iphone storyboard. Do I need to add an item to the plist for this other storyboard? At what level in the plist is this added? Another Scene Configuration? Another Window Application Session Role? Another Storyboard Name?

I'm running Xcode 16.3. Below are the instructions from TN3187: To configure your Info.plist for scene support, you should add a UIApplicationSceneManifest key with a scene configuration: Open your Xcode project. Select your app target. Navigate to the General settings for your app target. Enable the “Supports multiple windows” checkbox in the Deployment Info section. There is no checkbox - just an arrow that goes to the info tab Edit the Info.plist file and add a UIApplicationSceneManifest key [example follows] Where is the Info.plist file and how do I edit it? - none shown

When running on my iPhone SE3 under IOS 18.4.1, achievement banners show as expected. The same code running on my iPad Air2 under IOS 15.8.4, achievement banners do not show, but they are accepted (as shown in the GameCenterViewController). The banners also don't show when running the simulator under iPhone 16 Pro Max under IOS 18.2 or simulator under iPhone SE3 under IOS 18.3. I haven't tried others. [Note that I clear the achievements each run during test so that I can duplicate this]

Added achievements to my approved app. Added them for the next release version, which I am running in simulator. When I look at the Achievements page, I can see that there are 17 Achievements available (correct), but they all show as hidden, despite checking the "No" box in App Store Connect.

New to achievements. I added them in App Store Connect and want to test them. Apple Documentation says this: "Before you begin testing your GameKit configuration, you need to enable Debug Mode. In Xcode, choose Product > Scheme > Edit Scheme. From the Run configuration, select Options and toggle Enable Debug Mode. To begin testing your achievement configuration, open the game Progress Manager. In Xcode, choose Debug > GameKit > Manage Game Progress." Sounds easy enough, but there is no "GameKit" under Debug in Xcode 16.2.

This is the first time I have tried adding achievements to my games. The online documentation says: "Before you can access achievements in your code, you can configure them in Xcode and sync the configuration updates you make with App Store Connect. Begin configuring achievements by creating a GameKit configuration file. In Xcode, choose File > New > File from Template. Select GameKit File, and click Next. In the sheet that appears, enter a name for the configuration and click Create." Sounds easy - except Xcode 16.2 does not have a GameKit File as one of the Templates. Please advise on how to proceed and it would be nice if the documentation were updated.

Xcode 16.2. When calling openURL:options:completionHandler: when in the simulator for a link in the app store (for example: http://itunes.apple.com/us/app/slidewords/id503737864?mt=8) behavior is fine for simulated iPads, not for simulated iPhones. When the simulated device is an iPad, the call correctly opens the app store link. When the simulated device is an iPhone, an error message "Safari cannot open the page because the address is invalid." Note: the call works on an an actual iPhone (iPhone SE 3rd generation, unsure about other devices).

I have several apps where I successfully implemented Safe Area Margins, but this app uses a Tab Bar Controller and it ignores the safe areas. I am using Xcode 16.2, and Storyboards. The "Use Safe Area Layout Guides" is checked for every scene, yet none are using the safe area. Any clues?
