Error Domain=NSCocoaErrorDomain Code=4099Hmmm, that looks exactly like the error that I was under the impression we’d fixed in 10.13.4 (r. 36702504). At this point I’m going to have to revisit this issue in depth and that’s not something I can do in the context of DevForums.Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail = eskimo + 1 + @apple.com

UserInfo={NSDebugDescription=The connection to service created from an endpoint was invalidated from this process.} Obviously no clue what this means 🥲 But it seems that the extensions with the NEURLFilterControlProvider cannot even be launched for some reason?

Safari App Extension fails to connect to CloudKit daemon (cloudd) with XPC communication errors -- CKErrorDomain Code=6 / NSCocoaErrorDomain Code=4099 – Unable to connect to CloudKit daemon

I'm working on a macOS app with a Safari web extension. I'm trying to share a SwiftData model between devices using CloudKit synchronization. I am able to get synchronization in the main app on the same device, CloudKit sync works correctly — changes appear in the CloudKit Dashboard under com.apple.coredata.cloudkit.zone. However, in the Safari App Extension, data is saved locally and persists across launches, but never syncs to CloudKit. I have followed the recommended practices for configuring the App Group and entitlements, but the issue persists. Questions: Is there an official limitation preventing Safari App Extensions from connecting to the CloudKit daemon (cloudd)? If not, what entitlements or configuration changes are required for a Safari App Extension to successfully sync with CloudKit? Is the xpc_error=159 from bootstrap_look_up() a known sandbox restriction for this extension type? Any guidance from Apple engineers or others who have successfully used CloudKit from a Safari App Extension would be

Reply to How to activate NEPacketTunnelProvider?

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?
