I'm getting the exception:

CFNetwork SSLHandshake failed (-9807)

I assume the realm value I added is correct but I am not certain. Print() is used for testing that connection.

I solved it after making socket.disableSSLCertValidation = true and set the protocol as let socket = WebSocket(url: wsEndpoint, protocols: ["protocol_name"])
