NSCocoaErrorDomain

I switched to writing to a file instead and I get the same error: Error Domain=NSCocoaErrorDomain Code=513 You don’t have permission to save the file “testFromWidget.txt” in the folder “B6DF24C2-XXXX-XXXXX-XXX-XXXXXXX. UserInfo={NSFilePath=.../testFromWidget.txt, NSURL=.../testFromWidget.txt, NSUnderlyingError=0x1078790e0 {Error Domain=NSPOSIXErrorDomain Code=1 Operation not permitted}}

I'm not sure what's going on here, but I do have a few comments and questions: First off, are you using coordinated I/O for all of your actual access? The basic point of coordinate I/O is to prevent apps from making I/O calls before the system is actually ready for them to be made, which should make this sort of thing unnecessary: I/O may hang indefinitely, trying to read a file as it is arriving. This one I can work around by running the I/O in a thread created with the POSIX pthread_create and using pthread_cancel to kill it after a timeout. As a general note, I'm very skeptical of any usage of pthread cancellation. Our system's are basically built on two parallel system/IPC architectures (BSD an mach) which have never really been properly integrated. An API like pthread_cancel really only deals with the BSD architecture, which means the consequences to the mach side are... undefined. At a minimum it probably creates mach port leaks and at worst... well, the problem with mach is that the the worst is VERY d

Ok. I tried my user directory and the user directory. Same result: ❌ Échec lors de la copie : Error Domain=NSCocoaErrorDomain Code=4 Le fichier « 2019-BMW-X2-Specs-Build-Sheet.pdf » n’existe pas.

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

The error persists in the document folder and on the desktop. Here are the logs when droping from the document folder: Unable to open mach-O at path: default.metallib Error:2 ✅ PDF détecté ❌ Échec lors de la copie : Error Domain=NSCocoaErrorDomain Code=4 Le fichier « Facture - Contrôle Technique - Land Rover Defender - 118V.pdf » n’existe pas.

Thanks for the extra info. I see two errors here: The top-level error is NSCocoaErrorDomain code 4, which is NSFileNoSuchFileError. The underlying error is NSPOSIXErrorDomain code 2, which is ENOENT. Cocoa errors can be a bit ‘squishy’, meaning that the same error can come from a variety different sources. However, the presence of the ENOENT error suggests that this really is a file not found problem of some form. It looks like the source file is in the Downloads folder. That might be important because that folder is protected by MAC [1]. If you use the Finder to move the file to your home directory and then drag the file on to your app, does that work?
