Thanks for your suggestion, I have tried it before the when I added the TLS Options to NWParameters, the Client IP is down immediately. TCP options was still fine let tlsOptions = NWProtocolTLS.Options() let tlsParams = NWParameters(tls: tlsOptions, tcp: .init()) Btw, Unless I used the host name : "wss:X.X.X.X", sec_protocol_options_set_verify_block is never called.

Yes sure, we are in one team. It's my pleasure that we can discuss in that thread. Thanks for your quick response..

I want to create a utility app that can adjust the brightness of the menubar without changing the macOS brightness. Prior to changing this setting from the system or Apple script. I think it's better when my app launches without being at the forefront.
