As mentioned before, I am also using the recvfrom function to receive data. Do I still need to send anything to the server in order to get the privacy alert triggered (e.g. ping as discussed above)? Do I need to configure anything else other than adding NSLocalNetworkUsageDescription? I am building the app with Xcode 11 without getting the privacy alert. If I build the app with Xcode 12, the alert is not triggered, but data is received correctly. Any help?

On "14.2" Beta the app doesn't crash anymore. Thank you.
