May I have the simplest iOS14 code using Network Framework to setup an UDP Listener ?
Sending a message works but not receiving
Should I have to put the listener in background ?
Thanks

Take a look at the sample for Building a Custom Peer-to-Peer Protocol as this has a sample for NWListener. You will need to retrofit this class to use NWProtocolUDP, but that should be straight forward. Let me know if you have questions.

Code Block swiftlet udpOptions = NWProtocolUDP.Options()
let params = NWParameters(dtls: .init(), udp: udpOptions)
let listener = try NWListener(using: params)
