NWPathMonitor mocking for Simulator using Network Extension

Is it possible to mock the behavior of NWPathMonitor for a specific app? The scenario I want to support I've created an app called RocketSim, a developer tool for Xcode's Simulator. I've already created Airplane mode, which disables networking calls from URLSession from a specific bundle identifier app installed on the Simulator. Now, I want to support blocking NWPathMonitor as well. I believe the Simulator uses macOS's NWPathMonitor and does not use any specific HTTP request or similar to determine the reachability state. Is there a way I can make NWPathMonitor return unsatisfied when my 'airplane mode' is turned on? Potentially using a Network Extension?

Understanding PHPickerConfiguration.AssetRepresentationMode.current

The documentation for this API mentions: The system uses the current representation and avoids transcoding, if possible. What are the scenarios in which transcoding takes place? The reason for asking is that we've had a user reaching out saying they selected a video file from their Photos app, which resulted in a decrease in size from ~110MB to 35MB. We find it unlikely it's transcoding-related, but we want to gain more insights into the possible scenarios.

Network Extension Development Flow

I've been following these instructions and managed to get a development flow running: https://developer.apple.com/forums/thread/725805 However, my extension changes are only applied as follows: Change the code Remove the extension using OSSystemExtensionRequest.deactivationRequest Restart Mac If I don't do that, it seems that the old version of my extension keeps running. I confirmed this based on OSLogs that I added. In other words: how can I ensure during development my latest code gets executed?

Network Extension receives stop command right after start

Right after starting my Network Extension I see logs about it being stopped. This is unexpected, since I don't request a stop myself. See: Logs Secondly: I'm trying to build a Network Provider to stop any requests coming from a specific app. Am I correct I can do that using the NEFilterDataProvider without any filters configured? override func startFilter(completionHandler: @escaping (Error?) -> Void) { log.log(level: .debug, "startFilter NEW3") completionHandler(nil) }

Also, Sandbox enabled/disabled didn't make a difference.Any idea?
