SignalR-Swift is a client library for iOS based on https://github.com/DyKnow/SignalR-ObjC by DyKnow. It's built on top of AlamoFire and Starscream. SignalR-Swift is intended to be used along side ASP.NET SignalR, a new library for ASP.NET developers that makes it incredibly simple to add real-time functionality to your applications. What is "real-time web" functionality? It's the ability to have your server-side code push content to the connected clients as it happens, in real-time.

Installation

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like SignalR-Swift in your projects. See the "Getting Started" guide for more information. You can install it with the following command:

$ gem install cocoapods

Podfile

To integrate SignalR-Swift into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/kamrankhan07/SignalR-Swift.git'
platform :ios, '9.0' (2.1.6)
pod 'SignalRSwift', :git => 'https://github.com/kamrankhan07/SignalR-Swift.git', :tag => '2.1.6'


platform :ios, '10.0' (onwards)
pod 'Starscream', :git => 'https://github.com/kamrankhan07/Starscream'
pod 'SignalRSwift', :git => 'https://github.com/kamrankhan07/SignalR-Swift.git'

Then, run the following command:

$ pod install

Example Usage

Persistent Connection

using System.Threading.Tasks;
using Microsoft.AspNet.SignalR;

//Server
public class MyConnection : PersistentConnection 
{
    protected override Task OnReceived(IRequest request, string connectionId, string data) 
    {
        // Broadcast data to all clients
        return Connection.Broadcast(data);
    }
}

import SignalRSwift

//Client
var connection = Connection(withUrl: "http://localhost/endpoint/");

// register for connection lifecycle events
connection.started = {
    print("Connected")
}

connection.reconnecting = {
    print("Reconnecting...")
}

connection.reconnected = {
    print("Reconnected.")
}

connection.closed = {
    print("Disconnected")
}

connection.connectionSlow = { print("Connection slow...") }

connection.error = { error in
  print("Error")
}

connection.start()

Hubs

//Server
public class Chat : Hub 
{
    public void Send(string message)
    {
        // Call the addMessage method on all clients            
        Clients.All.addMessage(message);
    }
}

//Client
import SignalRSwift

// Connect to the service
var hubConnection = HubConnection(withUrl: "http://localhost/endpoint")

var chat = hubConnection.createHubProxy(hubName: "chat")

chat.on(eventName: "addMessage") { (args) in
  if let message = args[0] {
    print("Message: \(message)")
  }
}

// register for connection lifecycle events
hubConnection.started = {
    print("Connected")
}

hubConnection.reconnecting = {
    print("Reconnecting...")
}

hubConnection.reconnected = {
    print("Reconnected.")
}

hubConnection.closed = {
    print("Disconnected")
}

hubConnection.connectionSlow = { print("Connection slow...") }

hubConnection.error = { error in
  print("Error")
}

hubConnection.start()

Customizing Query Params

Persistent Connections

let qs = [
   "param1": "1",
   "param2": "another"
}
var connection = Connection(withUrl: "http://localhost/endpoint", queryString: qs)

Hub Connections

let qs = [
   "param1": "1",
   "param2": "another"
}
var hubConnection = HubConnection(withUrl: "http://localhost/endpoint", queryString: qs)

Customizing Request Headers

Persistent Connections

let headers = [
   "param1": "1",
   "param2": "another"
]
var connection = Connection(withUrl: "http://localhost/endpoint", queryString: qs)
connection.headers = headers

// alternative usage
var connection = Connection(withUrl: "http://localhost/endpoint", queryString: qs)
connection.addValue(value: "1", forHttpHeaderField: "param1")
connection.addValue(value: "another", forHttpHeaderField: "param2")

Hub Connections

let headers = [
   "param1": "1",
   "param2": "another"
}
var hubConnection = HubConnection(withUrl: "http://localhost/endpoint", queryString: qs)
hubConnection.headers = headers

// alternative usage
var hubConnection = HubConnection(withUrl: "http://localhost/endpoint", queryString: qs)
hubConnection.addValue(value: "1", forHttpHeaderField: "param1")
hubConnection.addValue(value: "another", forHttpHeaderField: "param2")
