NSCocoaErrorDomain

I'm seeing this error a lot in my console log of my iPhone 15 Pro (Apple Intelligence enabled): com.apple.modelcatalog.catalog sync: connection error during call: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service named com.apple.modelcatalog.catalog was invalidated: failed at lookup with error 159 - Sandbox restriction. UserInfo={NSDebugDescription=The connection to service named com.apple.modelcatalog.catalog was invalidated: failed at lookup with error 159 - Sandbox restriction.} reached max num connection attempts: 1 Are there entitlements / permissions I need to enable in Xcode that I forgot to do? Code example Here's how I'm initializing the language model session: private func setupLanguageModelSession() { if #available(iOS 26.0, *) { let instructions = my instructions do { languageModelSession = try LanguageModelSession(instructions: instructions) print(Foundation Models language model session initialized) } catch { print(Error creating language model session: (error)) lang

Hi, I am developing a Screen Time App and I am having issues with the ShieldConfigurationExtension (ShieldConfigurationDataSource). I know this extensions is sandboxed but I should be able to read data from the main app. I am using SwiftData as my database, but I am unable to initialize it in the extensions with an error indicating insufficient file permissions. I have App Group set up and I am able to share data using UserDefaults but that is just inconvenient. Is there any way I could just open the SwiftData in read only mode so that I could display the user some info on the shield? SwiftData Init: private func setupContainer() throws { let schema = Schema([ DogEntity.self, HouseEntity.self ]) // Use app group container if available let config: ModelConfiguration if let containerURL = FileManager.default.containerURL( forSecurityApplicationGroupIdentifier: group.(Bundle.app.bundleIdentifier ?? ) ) { config = ModelConfiguration(schema: schema, url: containerURL.appendingPathComponent(default.sqlite)) } else

I have tried to set up iCloud sync. Despite fully isolating and resetting my development environment, the app fails with: NSCocoaErrorDomain Code=134060 (PersistentStoreIncompatibleVersionHashError) What I’ve done: Created a brand new CloudKit container Created a new bundle ID and app target Renamed the Core Data model file itself Set a new model version Used a new .sqlite store path Created a new .entitlements file with the correct container ID Verified that the CloudKit dashboard shows no records Deleted and reinstalled the app on a real device Also tested with “Automatically manage signing” and without Despite this, the error persists. I am very inexperienced and am not sure what my next step is to even attempt to fix this. Any guidance is apprecitated.

I have an accessory with MFi authenticaiton passed(got 0xAA05) and identification accepted (got 0x1D02). But when I try to open the target stream by using iAP2 EA session framework, I always enounter the same error looking like: XPC connection error: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service named com.apple.accessories.externalaccessory-server was invalidated from this process. UserInfo={NSDebugDescription=The connection to service named com.apple.accessories.externalaccessory-server was invalidated from this process.} anybody can tell me what it related with? And what can I do to go through it quickly? Thank you much in advance.

Hi everyone, I'm facing an issue where I cannot write a file to a shared App Group container in my tvOS app when running on a real device. My code works perfectly on the simulator, but fails on a physical device with a permissions error. I’ve set up an App Group with a custom identifier (e.g., group.), and it’s correctly configured in the Capabilities section of Xcode for both my main app and widget targets. Here’s the code I’m using to save a test file: func saveTestFile() { guard let groupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: group.) else { print(Couldn't access the Group URL.) return } let containerURL = groupURL.appendingPathComponent(Library, isDirectory: true) if FileManager.default.isWritableFile(atPath: containerURL.path) { print(Directory IS writable) } else { print(Directory IS NOT writable) } let fileURL = containerURL.appendingPathComponent(test.txt) let content = Hello App Group! do { try content.write(to: fileURL, atomically: true, encoding: .utf8) print(F

I'm unable to get live activity to show up in my app so I started to play with the demo app Emoji Rangers. The demo project initially only created a live activity in-app and then you're able to update it via the demo buttons. I added the following code to have it be able to start a live activity from the backend: func observePushToStartToken() { Task { for await data in Activity.pushToStartTokenUpdates { let token = data.map {String(format: %02x, $0)}.joined() // Send token to the server print(got PUSHTOSTART TOKEN: (token)) } } } I get the token and then I use it to send this payload that should start the activity: { aps:{ timestamp:1743719911, event:start, content-state:{ currentHealthLevel:100, eventDescription:Adventure has begun!, supercharged:true }, input-push-token:1, attributes-type:AdventureAttributes, attributes:{ currentHealthLevel:100, eventDescription:Adventure has begun!, supercharged:true }, alert:{ title:{ loc-key:%@ is on an adventure!, loc-args:[ Power Panda ] }, body:{ loc-key:%@ found a s

Security scoped bookmarks that were created before updating to macOS 14.7.5 cannot be resolved anymore after updating to macOS 14.7.5. Reproduction: Sandboxed app on macOS version 14.7.4 Create and store a security scoped bookmark to a user selected folder: let url: URL = let data = try url.bookmarkData(options: [.withSecurityScope], includingResourceValuesForKeys: nil, relativeTo: nil) Update to macOS 14.7.5 Resolve the previously stored bookmark: let data: Data = var stale: Bool = true let url = try URL(resolvingBookmarkData: data, options: [.withSecurityScope], relativeTo: nil, bookmarkDataIsStale: &stale) Expected: The bookmark is resolved correctly and the resulting url can be used to access the folder/file in the sandboxed app after starting access. Observed: URL(resolvingBookmarkData:) throws an error: Error Domain=NSCocoaErrorDomain Code=259 The file couldn’t be opened because it isn’t in the correct format. New security scoped bookmarks created on macOS 14.5.7 can be resolved without

I support a pair of iOS apps that use a file provider extension. One app exposes a file provider extension, including a file provider extension service and the other app interacts with the file provider extension and uses the service. On iOS 18.3 and before, this all works fine. On iOS 18.4, getFileProviderServicesForItem fails when called from the consuming app with: Error Domain=NSCocoaErrorDomain Code=513 The file couldn’t be saved because you don’t have permission. The supportedServiceSources method in the service hosted by the provider app is never invoked when this occurs. Is there some change to the mechanism for iOS 18.4 that I've not found yet?

I have a basic setup following WWDC 2020 on Safari Web Extensions and another one on XPC. The video even mentions that one can use UserDefaults or XPC to communicate with the host app. Here is my setup. macOS 15.2, Xcode 16.2 A macOS app (all targets sandboxed, with an app group) with 3 targets: SwiftUI Hello World web extension XPC Service The web extension itself works and can update UserDefaults, which can then be read by SwiftUI app - everything works by the book. The app can communicate to the XPC service via NSXPCConnection - again, everything works fine. The problem is that the web extension does not communicate with XPC, and this is what I need so that I can avoid using UserDefaults for larger and more complex payloads. Web Ext handler code: class SafariWebExtensionHandler: NSObject, NSExtensionRequestHandling { func beginRequest(with context: NSExtensionContext) { // Unpack the message from Safari Web Extension. let item = context.inputItems[0] as? NSExtensionItem let message = item?.userInfo?[SFExte

Hello, community, I'm using an HTML editor in a .NET MAUI application running on macOS, and I'm encountering some unexpected behavior during text editing: Double-click text selection disappears after approximately one second. Styles randomly revert or are applied to the wrong text unexpectedly. It appears to be related to macOS spell checking. When using editable elements (, or with contenteditable), the system enables spell checking by default. During this, MAUI attempts to communicate with a system process: com.apple.TextInput.rdt, which is not running, leading to repeated errors like: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service named com.apple.TextInput.rdt was invalidated: failed at lookup with error 3 - No such process. Question: What is com.apple.TextInput.rdt, and why might it not be running? Thank you for any help!
