I have a SpriteKit project in which I'm seeing the following error repeatedly printed to the logs when testing on a real device: Execution of the command buffer was aborted due to an error during execution. Insufficient Permission (to submit GPU work from background) This happens when the app is in the background state. Now, it's pretty obvious what's going on: SpriteKit uses Metal, and the latter is committing new work to the GPU when the app is backgrounded (which is something you can't do). I've confirmed this theory by not loading my SpriteKit scenes. If I don't load the scenes, the problem does not occur. This is a strange problem because, according to Apple's documentation - https://developer.apple.com/documentation/spritekit/skview/1519654-ispaused, SpriteKit is paused/resumed automatically when the app goes from/to the background: When an application moves from an active to an inactive state, isPaused is automatically set to true. When an application returns to an active state, isPaused is automatically set to its previous value. So, I would expect new work to stop being sent to the GPU. Question: How do I resolve this error?

I have a SwiftUI app with a widget. When I run the app via Xcode (either straight to my device or on the simulator), the widget works exactly as expected. However, when I run the app through TestFlight, the widget appears, but does not show any data. It shows an image, and "SCORE" and "LEVEL" text -- but not the actual score and level. I've seen some posts on Apple Developer forums about similar problems. One accepted answer says the following: Make sure that you use Xcode 12 beta 4 and iOS 14 beta 4 on your devices. Make sure that you have placeholder(in:) implemented. Make sure that you don't have placeholder(with:) because that's what the previous beta of Xcode was suggesting with autocompletion and without that you won't get your placeholder working. I think this whole problem is caused by the WidgetKit methods getting renamed but that's another story. As per the release notes, you need to set "Dead Code Stripping" to NO in your extension target's build settings. This is only necessary for the extension's target. When uploading your archive to the App Store Connect, uncheck "Include bitcode for iOS content". Delete your old build from a device when installing a new beta. I've implemented these suggestions, to no avail. Here's my code for the widget. It first fetches game data via CloudKit, then creates a timeline: import WidgetKit import SwiftUI import CloudKit struct WidgetCloudKit { static var gameLevel: Int = 0 static var gameScore: String = "" } struct Provider: TimelineProvider { private var container = CKContainer(identifier: "MyIdentifier") static var hasFetchedGameStatus: Bool = false func placeholder(in context: Context) - SimpleEntry { return SimpleEntry(date: Date(), gameLevel: 0, gameScore: "0") } func getSnapshot(in context: Context, completion: @escaping (SimpleEntry) - ()) { let entry: SimpleEntry if context.isPreview && !Provider.hasFetchedGameStatus { entry = SimpleEntry(date: Date(), gameLevel: 0, gameScore: "0") } else { entry = SimpleEntry(date: Date(), gameLevel: WidgetCloudKit.gameLevel, gameScore: WidgetCloudKit.gameScore) } completion(entry) } func getTimeline(in context: Context, completion: @escaping (TimelineEntry) - ()) { let pred = NSPredicate(value: true) let sort = NSSortDescriptor(key: "creationDate", ascending: false) let q = CKQuery(recordType: "gameData", predicate: pred) q.sortDescriptors = [sort] let operation = CKQueryOperation(query: q) operation.desiredKeys = ["level", "score"] operation.resultsLimit = 1 operation.recordFetchedBlock = { record in DispatchQueue.main.async { WidgetCloudKit.gameLevel = record.value(forKey: "level") as? Int ?? 0 WidgetCloudKit.gameScore = String(record.value(forKey: "score") as? Int ?? 0) Provider.hasFetchedGameStatus = true var entries: [SimpleEntry] = [] let date = Date() let entry = SimpleEntry(date: date, gameLevel: WidgetCloudKit.gameLevel, gameScore: WidgetCloudKit.gameScore) entries.append(entry) let nextUpdateDate = Calendar.current.date(byAdding: .minute, value: 15, to: date)! let timeline = Timeline(entries: entries, policy: .after(nextUpdateDate)) completion(timeline) } } operation.queryCompletionBlock = { (cursor, error) in DispatchQueue.main.async { if let error = error { print("queryCompletion error: \(error)") } else { if let cursor = cursor { print("cursor: \(cursor)") } } } } self.container.publicCloudDatabase.add(operation) } } struct SimpleEntry: TimelineEntry { var date: Date var gameLevel: Int var gameScore: String } struct WidgetEntryView : View { var entry: Provider.Entry var body: some View { GeometryReader { geo in VStack { Image("widgetImage") .resizable() .aspectRatio(contentMode: .fit) .frame(width: geo.size.width) HStack { VStack { Text("LEVEL") Text(entry.gameLevel == 0 ? "-" : "\(entry.gameLevel)") } VStack { Text("SCORE") Text(entry.gameScore == "0" ? "-" : entry.gameScore) } } } .unredacted() } } } @main struct Widget: SwiftUI.Widget { let kind: String = "MyWidget" var body: some WidgetConfiguration { StaticConfiguration(kind: kind, provider: Provider()) { entry in WidgetEntryView(entry: entry) } .configurationDisplayName("Game Status") .description("Shows an overview of your game status") .supportedFamilies([.systemSmall]) } } Question: Why isn't my widget working when tested via TestFlight? What am I doing wrong? Thank you!

Because my app is going to show advertisements, it's supposed to target users 13 years of age and older. So, I open App Store Connect and go to "Age Rating" - "Edit". I'm presented with a questionnaire that mentions all kinds of stuff -- violence, gambling, unrestricted web access, etc. In order to get my app's Age Rating to 13, I would have to select some of these categories. But my app will have none of that stuff, and I certainly wouldn't want any of those categories to be publicly visible if I did select them! Question: Is there an alternate method for setting an app's Age Rating, as it will appear on the App Store? Via Xcode maybe? Thank you!

According to the documentation, - https://developer.apple.com/documentation/safariservices/supporting_associated_domains I need to add a file to my website called apple-app-site-association without an extension in order to utilize App Clips: To add the associated domain file to your website, create a file named apple-app-site-association (without an extension). However, I can't seem to accomplish that. According to iPage support, it's not possible to have a file without an extension. Question: Is it truly necessary for this file to be without an extension, or is there an acceptable extension I can use? What would you recommend I do, here, since iPage says it's not possible? Thank you!
