How to connect with Socket.io? Swift 4

Question

I have read the latest documentation of Socket.io for Swift. And there is an example of a new connection:

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

So I have created a class SocketIOManager, like this:

class SocketIOManager: NSObject {

    static let manager = SocketManager(socketURL: URL(string: "myurl.com:443"))
    static let socket = manager.defaultSocket

    class func connectSocket(){
        socket.connect()
    }

    class func reciveMessage(){    
            socket.on("new-message-mob") { (dataArray, ack) in
                print(dataArray.count)
            }
    }
}

And then I just invoke the method SocketIOManager.connectSocket() in my ViewController. But the server produce the error. I don't develop the server side. I just need to know - did I create connection properly? How do you connect to socket through Socket.io these days?

P.S Server error - jwt must be provided (it seems like no token, but there is).

UPDATE (with dummy values):

I'm passing token like this:

static let manager = SocketManager(socketURL: URL(string: "https://myurl:443?token=\(token)")!)
static let socket = manager.defaultSocket

> `it seems like no token, but there is`. But your code doesn't have token. Are you sure that you pass the token? — pacification, Mar 26 '18 at 12:26
I pass a token like this: static let manager = SocketManager(socketURL: URL(string: "https://myurl.com:443?token=\(token)")!). But I'm not sure how to pass URL parameters. — Nastromo, Mar 26 '18 at 12:30
check again how you put token. Can we see an example with dummy values? — Enea Dume, Mar 26 '18 at 12:33

So, to solve this issue we have to do a couple of actions:

Add a .connectParams(["token": token]) for manager.config - in my case I have to use "token" key as URL parameter.
Add a .secure(true) parameter for manager.config.
Add an "App Transport Security Settings" key in info.plist (Dictionary type) and sub key "Allow Arbitrary Loads" (boolean type) with YES value.

CODE:

class SocketIOManager: NSObject {

    static let manager = SocketManager(socketURL: URL(string: "https://yoururl.com:443")!, config: [.log(true), .compress])
    static let socket = manager.defaultSocket


    class func connectSocket(){
        self.manager.config = SocketIOClientConfiguration(
            arrayLiteral: .connectParams(["token": token], .secure(true)
        )
        socket.connect()
    }

    class func disconnectSocket(){
        socket.disconnect()
    }
}

It looks like you set the token in wrong place. According to the issue, token should be set as header parameter in configuration:

manager.config = SocketIOClientConfiguration(
    arrayLiteral: .compress, .connectParams(["Authorization": token])
)

Try to manage your token this way.

Yes, it's solved my issue. But there are more settings we have to add to run this bad boy. See my answer below if someone faced the same problem. – Nastromo Mar 26 '18 at 15:04
