Hi, Just trying to bump this issue as it's really crucial for me. Currently in order to workaround this problem I run the CMake twice, once to generate Xcode project and another time to build from regular Makefile. the Makefile build is meant only for running the clang-tidy, while the Xcode project used for debugging ... however, it's very cumbersome to make the extra builds, and I'm sure there maybe an easier workaround like Xcode plugin or such ...

Ok, So i've implemented my receive function to call new receiveMessageWithCompletionHandler upon successful completion and it's working great. But now I've got another issue in the same area... If I'm sendPingWithPongReceiveHandler method as a webSocket heartbeat, how can I ensure that the Pong responses wouldn't get caught by the receiveMessage completion handler, but by the pongReceiveHandler ? Are the Pong responses differ from other responses in terms of routing so that each trigger a different callback by design ?

If you mentioned the proxy provider. I also had an idea to use NETransparentProxyNetworkSettings to create some local proxy and use Include/ExcludeMethodRules in order to decide what will enter my tunnel and what traffic goes to the default interface (like en0). Can this class also replace the NEPacketTunnelProvider in creating and starting the tunnel (along with the tunnel protocol), or it can just be used for splitting the relevant traffic to the tunnel, which will be implemented by the provider itself ? thanks!
