NSCocoaErrorDomain Error Code 4

Why would my app not have permission to view the document when it's from the files app? Error Domain=NSCocoaErrorDomain Code=257 The file “afile.pdf” couldn’t be opened because you don’t have permission to view it. UserInfo={NSFilePath=/private/var/mobile/Containers/Shared/AppGroup/xxxxxxxx/File Provider Storage/afile.pdf, NSUnderlyingError=0x281f4f150 {Error Domain=NSPOSIXErrorDomain Code=1 Operation not permitted}}

Ahh hmm I spoke to soon.. I also get an error using HMAccessoryBrowser and then calling addAccessory on the home, so it seems the issue isn't with discovering accessories but adding them to the home. not sure if these error message are any use, but...

While still working on write to file, I'm running into this issue now. Error Domain=NSCocoaErrorDomain Code=513 UserInfo={NSFilePath=, NSUnderlyingError=0x600000c782a0 {Error Domain=NSPOSIXErrorDomain Code=1}}. I read the thread https://developer.apple.com/forums/thread/63075 and added .noFileProtection to my write method call, but that didn't fix the issue. Since the network extension works as root to write to file and I want to write to /private/tmp/example.txt, why am I seeing this error?

just as a followup in case anyone is still wondering.. SCSensitivityAnalyzer does seem to be working as intended now on mac (incl in widgets & the widget simulator), and on device on iOS.. however it doesn't work in the iOS simulator, which may be expected? tho i can't see anything about it in the docs at any rate, the simulator errors i get look like: Error fetching CommSafety configuration from ScreenTime: Error Domain=NSCocoaErrorDomain Code=4097 connection to service named com.apple.ScreenTimeAgent.communication UserInfo={NSDebugDescription=connection to service named com.apple.ScreenTimeAgent.communication} and Failed to get contents of directory: /Users/bloop/Library/Developer/CoreSimulator/Devices/7E385B3A-40AF-4CF1-AA9E-723BB46141E7/data/Library/Biome/streams/restricted/SensitiveContentAnalysis.MediaAnalysis/local, error: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service named com.apple.biome.access.

Im getting similar error while using CoreTelephony on unwantedCommunication Extension.I have linked CoreTelephony as linked library and this is my troublesome code.. let networkInfo = CTTelephonyNetworkInfo() let carrier = networkInfo.subscriberCellularProvider print(carrier);and my error log is: 2018-08-08 14:24:55.100318-0400 ReportSpam1Extension[4192:295308] [NetworkInfo] Descriptors query returned error: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated.

BTW - on a separate note, with Xcode 7.1 beta 3 (the one that just came out today), I import an xliff file that works under 7.01 - and it gets me to the window where I approve the import and then I get this error (radar 22997699):XLIFF target-language attribute missingBasically I'm just seeing XCode's localization tools go downhill big time since Xcode 7. It seems like every release does not fix any of the issues that I talked to you about at WWDC and introduces new ones. I can't tell you how disappointed and discouraging this is. I've put in so many bug reports only to see things get worse.I tell you, if you sat down with me for a few days and we ran through my project back and forth, you would fix so many issues.Console:10/6/15 2:59:51.695 PM Xcode[61177]: Failed to connect (comparisonSplitView) outlet from (DVTComparisonScrollCoordinator) to (DVTComparisonSplitView): missing setter or instance variable10/6/15 3:00:05.349 PM Xcode[61177]: [default] Failed to updated bookmark for item (null) [063E9D

Thanks for your reply! I've tried both methods, unfortunately without success. The canonical path method did not resolve /System/Volumes/Data/Test/ to /Test/ and the string replacement results in error Domain=NSCocoaErrorDomain Code=260 Scoped bookmarks can only be created for existing files or directories

I'm fairly certain it's related to entitlements and possible App Groups. I'm now getting : [OpenSavePanels] Unable to display save panel (unrecognized error: Error Domain=NSCocoaErrorDomain Code=4099 The connection to service created from an endpoint was invalidated from this process. UserInfo={NSDebugDescription=The connection to service created from an endpoint was invalidated from this process.})
