NSCocoaErrorDomain

I've built a macOS app (in Xcode 12.5) with Finder extensions, and set all the components to share a common app group, with the name correctly formatted as CD......7C.com.orexresearch.EMPSecure.group . Up till now, it's been working fine for everything I've needed it to do, with app and extension both accessing common files. But now I need to do file downloads for the FileProvider extension, and these are failing. I know part of the problem is to do with the App group -- in the main app, the download works if I initialise the Dropbox component without the app group identifier, but if I switch Dropbox to use the app group identifier, it fails repeatedly in both the main app and the extension: error 21:36:44.487814+1100 EMPFileProvider BackgroundSession <7764EC70-AC7F-46F4-91DC-547FAA23249C> an error occurred on the xpc connection to setup the background session: Error Domain=NSCocoaErrorDomain Code=4097 UserInfo={NSDebugDescription=} error 21:36:44.487893+1100 EMPFileProvider BackgroundSession &

Hi there, I just downloaded the Sample Code provided by de developer documentation in order to run a simple Client-Server app with TVML Kit for tvOS. https://developer.apple.com/documentation/tvmljs/creating_a_client-server_tvml_app I'm following the docs step by step and after running the server in the terminal. I would go and open the project in Xcode and hit the build button. It would lauch the simulator but I get the following error in the simulator: This operation couldn't be completed (TVMLKitErrorDomain error 3.) And in my console I would get this: CreateTVMLApp[82816:2094742] [Image] _TVAssetGroup failed to purge cache path: Shared Asset Group, Error Domain=NSCocoaErrorDomain Code=4 “SharedImageCache” couldn’t be removed.

As I mentioned in this thread https://developer.apple.com/forums/thread/695207 I want my containing app to be active after Mac restarts. I thought about something that could work - I wrote a helper embedded app which will be added to the login items, and after a restart this helper app will open the containing app. However, after archiving the project (with developer ID, it will be distributed outside the App Store), I see the following error at the Console: Non-fatal error enumerating at , continuing: Error Domain=NSCocoaErrorDomain Code=260 The file “PlugIns” couldn’t be opened because there is no such file.

Is it possible to write to an App Group's Container folder or UserDefaults from an iOS Thumbnail Extension or QuickLook Extension? It doesn't work. It does work for a Widget extension. I've added the App Group to the Entitlements of each extension. For writing a file to App Group Container I get Error Domain=NSCocoaErrorDomain Code=513 Du hast nicht die Zugriffsrechte, um die Datei „quicklook 01 current.log“ im Ordner „DocumentInvestigation“ zu sichern.

Hi, I'm trying to write a Quick Look extension for my iOS app. However, I'm having issues initializing AVAudioEngine in my QLPreviewingController subclass from preparePreviewOfFile. The following error messages are printed to the console after attempting to initialize AVAudioEngine, and the Quick Look Extension crashes with EXC_BAD_ACCESS. The same code works fine within the main iOS app. It also works on macOS inside a Catalyst app on the macOS Monterey RC when previewing a file in the Finder. I've also filed feedback with feedback number FB9713048. Thanks for taking a look at this.

Hi All I am hitting an issue when developing an app that uses the CloudKit Public DB. I am relatively new to this, and I may be doing something wrong. I have distilled the issue to use just the template app that comes when you create a new Core Data with iCloud app, and detailed the steps below. My question is basically, am I doing something stupid? If I'm not then seems likely it's a bug in Xcode and I'll just have to wait. In a nutshell, syncing to the public DB works for the first run of the app only. Stopping and restarting the app seems to throw errors and cause the mirroring delegate to fail. Step by simple step, I can recreate my issue with this: Create App with Use Core Data and Host in ICloud - interface is SWiftUI In project signings and capabilities add iCloud and Background Modes In nearly appeared iCloud section enable Cloudkit and choose or create a container In newly appeared Background Modes section enable Remote Notifications In persistence.swift add : import CloudKit Still in persistence.swi

I’m converting a MusicKit app from iOS to macOS with Catalyst but can’t get the player to work.
