NSCocoaErrorDomain Error Code 4

@logicat I have the same problem as you. Have you found the reason?Error Domain=NSCocoaErrorDomain Code=512 wei neng cun chu gai wen jian。 UserInfo={NSUserStringVariant=Folder}。 And @eskimo it‘s a system problem? I don't have any ideas about this.

I'm also experiencing a similar issue. One user (out of thousands) is getting a 512 error – NSFileWriteUnknownError when the iOS app attempts to write a file to the caches directory or the documents directory.The user is on iOS 13.3, and logging the error shows Error Domain=NSCocoaErrorDomain Code=512 The file couldn’t be saved. UserInfo={NSUserStringVariant=Folder}

DocumentGroup is still broken for me even on the RC beta build. I see the following error: Failed to initialize CloudKit metadata: Error Domain=NSCocoaErrorDomain Code=134407 Request 'FB45661A-3619-4593-A7D1-2E164C9C2667' was cancelled because the store was removed from the coordinator. This doesn't appear on WindowGroup.

created FB8908465 i tried locations obtained with NSTemporaryDirectory (also /tmp /private/tmp /var/tmp) and NSSearchPathForDirectoriesInDomains + .cachesDirectory in with user, local, network and system domains. consistently getting this error: NSCocoaErrorDomain Code=513 You don’t have permission to save the file

on MacOS 14.5, the app on Mac also crash with the same error Unresolved error loading container Error Domain=NSCocoaErrorDomain Code=134060 A Core Data error occurred. UserInfo={NSLocalizedFailureReason=Unable to find a configuration named 'default' in the specified managed object model.} I think there is something todo with MacOS 14.5 and iOS 17.5.....

Hello! I crated the support incident and today as I was trying again and I realized my app was sandbox. After dealing with that this is what I have: let service = daemonConnection.remoteObjectProxyWithErrorHandler { err in print(Received error: (err.localizedDescription)) } as? MyServiceProtocol which prints: Received error: Couldn’t communicate with a helper application. or Received error: Error Domain=NSCocoaErrorDomain Code=4097 connection to service named com.serviceName UserInfo={NSDebugDescription=connection to service named com.serviceName }

Your issue is that URL(string:) expects a valid URL with a scheme (like file://), but you're passing a file path directly. It is similar to the following error:ErrorDomain = NsCocoaErrorDomain & ErrorCode = 4 Instead, you should use URL(fileURLWithPath:) for file paths. Here's the fixed code: var tempString = String() for Rezept in alleRezepte { tempString += (Rezept.name), (Rezept.description), (Rezept.nutrients), (Rezept.whatToDo)n } if let dirs = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first { let path = dirs.appending(/rezepte.csv) let url = URL(fileURLWithPath: path) do { try tempString.write(to: url, atomically: true, encoding: .utf8) print(Daten gesichert) } catch { print(Error saving file: (error)) } }

I'm seeing the same issue with my app. When I restart downloading of a content that previously failed, it sometimes fails with Error Domain=NSPOSIXErrorDomain Code=2 No such file or directory UserInfo={NSErrorFailingURLKey=xxx, NSErrorFailingURLStringKey=xxx}. It will sometimes recover after trying several times. Sometimes I had to reinstall the app to recover from this issue. I see an other error in console that could be related to this issue.Error removing item at url:file:///private/var/mobile/Containers/Data/Application/E58771BB-D7DE-5B6E-547FE8B44E25/Library/Caches/com.apple.nsurlsessiond/Downloads/XXXX/,error:Error Domain=NSCocoaErrorDomain code=4 couldn't be removed.UserInfo={NSFilePath=/private/var/mobile/Containers/Data/Application/E58771BB-D7DE-5B6E-547FE8B44E2/Library/Caches/com.apple.nsurlsessiond/Downloads/XXX,NSUserStringVariant=(Remove), NSUnderlyingError=0X153e32f90{Error Domain=NSPOSIXErrorDomain code=2 No such file or di

The issue exists in Xcode 13.4, iOS 15.5.

How about adding a function to ErrorType enum that would construct an NSError with an underlying error?enum DocumentError: ErrorType { case CantSave func withUnderlying(error: ErrorType?) -> NSError { guard let error = error else { return self as NSError } let info = [NSUnderlyingErrorKey: error as NSError] return NSError(domain: _domain, code: _code, userInfo: info) } } let cocoaError = NSError(domain: NSCocoaErrorDomain, code: NSFileWriteFileExistsError, userInfo: nil) let error = DocumentError.CantSave.withUnderlying(cocoaError)

I'm also seeing a similar behavior when trying to load the file representation using public.item UTI for Live Photos that were just taken or were selected and probably downloaded from icloud. If I try again the same images on a second or third time they seem to be loading just fine. If I use public.image it works just fine, note that it is on iOS 17 public beta. Exception: Error Domain=NSItemProviderErrorDomain Code=-1000 Cannot load representation of type public.item UserInfo={NSLocalizedDescription=Cannot load representation of type public.item, NSUnderlyingError=0x281b031e0 {Error Domain=NSCocoaErrorDomain Code=4097 Couldn’t communicate with a helper application.
