"Got unknown error from server ..." using Socket.io on Swift

I'm trying to connect to my Xcode Server's internal socket.io. I initialize the client using this:

self.socket = SocketIOClient(socketURL: NSURL(string: "https://37.203.216.82")!, options: [.Path("/xcode/internal/socket.io"), .Log(true), .Reconnects(true), .ForceNew(true), .SessionDelegate(self), .SelfSigned(true)])

But when I use self.socket.connect() I get this response:

2016-07-15 16:13:49.179 MyApp[84260:1941316] LOG SocketIOClient: Adding handler for event: connect
2016-07-15 16:13:49.180 MyApp[84260:1941316] LOG SocketIOClient: Adding handler for event: integrationStatus

2016-07-15 16:13:49.324 MyApp[84260:1941786] ERROR SocketIOClient: Got unknown error from server Welcome to socket.io.

"Got unknown error from server Welcome to socket.io."
)

I've tried changing the path to the socket.io.js file or xcode/internal/socket.io/1/ but it all gives the same response, instead, Welcome to socket.io is replaced by the contents of the file there.

Socket.IO-Client-Swift (16.0.1): version, need to add: .forceWebsockets(true).

Example:

let manager = SocketManager(socketURL: URL(string: "http://localhost:8080")!, config: [.compress, .forceWebsockets(true)])
let socket = manager.defaultSocket

I have updated swift client framework to the latest 16.0.1 version. But this error happened. There is an open issue also: https://github.com/socketio/socket.io-client-swift/issues/1355

I have fixed this by reverting to the old stable version:

pod 'Socket.IO-Client-Swift', '~> 15.2.0'

Check socket.io version on both server and client side, mismatch of both may be cause of this error

Try putting ws as the protocol, like this:

... NSURL(string: "ws://37.203.216.82") ...
