NSCocoaErrorDomain Error Code 4

Update:I've stripped down the application to a single page with a label. No assets. No network requests.Again, it launches fine with local builds and spins forever and eventually crashes with enterprise builds.I checked out the logs and sure enough there is an error:Hub connection error Error Domain=NSCocoaErrorDomain Code=4097 The operation couldn’t be completed. (Cocoa error 4097.) (connection to service named com.XXX.watchkitextension) <Notice>: (Error) WatchKit: <SPCompanionAppServer.m __51-[SPCompanionAppServer sendToRemoteInterface:call:]_block_invoke519:914> activePlugInForIdentifier: returned nil for application com.XXX.watchkitappI've googled the error code quite a bit but nothing concrete has surfaced.Anyone @ Apple have any idea of what is going on?

I'm experiencing the same problem in Firefox 134.0 (aarch64) on macOS 14.6.1 (Apple M1). Console 1.1, shows these messages when connected to my iPhone 14 running iOS 18.1.1: error 14:43:31.069080+0000 PassbookUIService Codable: Failed to decode Merchant Session Created: Error Domain=NSCocoaErrorDomain Code=4864 UserInfo={NSCodingPath=, NSDebugDescription=} error 14:43:31.069103+0000 PassbookUIService Session 12311: Fatal Error: Failed to decode merchant session created

I think it's quite likely that the sandbox is blocking access to Core Data. I'm using it via Swift Data: do { container = try ModelContainer( for: Settings.self, configurations: ModelConfiguration(allowsSave: allowsSave) ) context = ModelContext(container) } catch { fatalError(*** Failed to create BreakManager: (error)) } I get an error when I try to create the ModelContainer: Failed to register for com.apple.managedconfiguration.effectivesettingschanged: 9 Could not register for user invalidated notifications; status = 9 error: (3) access permission denied error: Encountered exception error during prepareSQL for SQL string 'SELECT TBL_NAME FROM SQLITE_MASTER WHERE TBL_NAME = 'Z_METADATA'' : access permission denied with userInfo { NSFilePath = /private/var/mobile/Containers/Shared/AppGroup//Library/Application Support/default.store; NSSQLiteErrorDomain = 3; } while checking table name from store: error: addPersistentStoreWithType:configuration:URL:option

Based from response, the file is temporarily downloaded in file:///var/mobile/Library/Caches/com.apple.nsurlsessiond/Downloads/xxxxx/CFNetworkDownload_qb9hwG.tmp I cannot copy this file to my download location since I am encountering an error: (NSError) error = 0x00000002818928e0 Error Domain=NSCocoaErrorDomain Code=257 The file CFNetworkDownload_qb9hwG.tmp could not be opened because you do not have permission to view it.

Hi Kevin Elliott, Here I'm adding the exact error message that I have got while requesting callkit transaction (Error?) domain: NSCocoaErrorDomain - code: 4097 { _userInfo = 0x000000012782a220 1 key/value pair { [0] = { key = 0x00000001f9af9c30 NSDebugDescription value = 0x0000000114f76d80 connection to service with pid 144 named com.apple.callkit.callcontrollerhost } } } And error's description is Couldn't communicate with a helper application. Please check and let us know if any further information needed. Thanks & Regards, Kishore

Just a heads up for my fellow Googlers, I was having trouble implementing this in my app. Using the simulator, iPhones would work, but iPads would not. I was seeing this error:error: Error Domain=NSCocoaErrorDomain Code=4 The file doesn't exist. UserInfo={NSUnderlyingError=0x60800044b3a0 {Error Domain=LSApplicationWorkspaceErrorDomain Code=-105 iconName not found in CFBundleAlternateIcons entry UserInfo={NSLocalizedDescription=iconName not found in CFBundleAlternateIcons entry}}}I was referencing these two example repos:https://github.com/steventroughtonsmith/AlternateIconTesthttps://github.com/iSame7/AlternateAppIconsI tried a bunch of debugging stuff and finally hit upon something that seems to help. I noticed if I replaced the contents of my AppIcon.appiconset/Contents.json file with one from the example repos, things seem to work on the iPad. I'm not 100% sure what's going wrong, but my Contents.json specifies a filename and I suspect that's the root o
