WSS/TLS websocket connection with Swift iOS


SOLVED (following answer)

I am using Starscream library to create a safe websocket wss in the test server we have a self-signed certificate and I find it impossible to make the connection.

var socket = WebSocket(url: NSURL(scheme: "wss", host: "selfsignedserver.com", path: "/")!)

Log

2014-12-16 10:38:10.260 pruebasignin[2135:363455] CFNetwork SSLHandshake failed (-9807)
websocket is disconnected: The operation couldn’t be completed. (OSStatus error -9807.)

and when I try to connect to a server certificate valid also fails to connect SOLVED

var socket = WebSocket(url: NSURL(scheme: "wss", host: "production.com", path: "/")!)

Log

websocket is disconnected: Invalid HTTP upgrade

Solution

  • I solved the problem by allowing self-signed certificates Starscream modifying the library. To this must be added the arcivo WebSocket.swift the following code:

    if url.scheme == "wss" || url.scheme == "https" {
            inputStream!.setProperty(NSStreamSocketSecurityLevelNegotiatedSSL, forKey: NSStreamSocketSecurityLevelKey)
            outputStream!.setProperty(NSStreamSocketSecurityLevelNegotiatedSSL, forKey: NSStreamSocketSecurityLevelKey)
    
            /* My code */
            var settings = Dictionary<NSObject, NSObject>()
            settings[kCFStreamSSLValidatesCertificateChain] = NSNumber(bool:false)
            settings[kCFStreamSSLPeerName] = kCFNull
    
            CFReadStreamSetProperty(self.inputStream, kCFStreamPropertySSLSettings, settings)
            CFWriteStreamSetProperty(self.outputStream, kCFStreamPropertySSLSettings, settings)
            /* End my code*/
    
        }
