Branch: master
Clone or download


A Swift SignalR Client for the Asp.Net Core version of SignalR



Add the following lines to your Podfile:

pod 'SwiftSignalRClient'

Then run:

pod install

Swift Packacge Manager

Add the following to your Package dependencies:

.package(url: "", .upToNextMinor(from: "0.5.0")),

Then include "SignalRClient" in your target dependencies. For example:

.target(name: "MySwiftPackage", dependencies: ["SignalRClient"]),


Add import SignalRClient to swift files you would like to use the client in.

A typical implementation looks like the following:

import Foundation
import SignalRClient

public class SignalRService {
    private var connection: HubConnection
    public init(url: URL) {
        connection = HubConnectionBuilder(url: url).withLogging(minLogLevel: .error).build()
        connection.on(method: "MessageReceived", callback: { (args, typeConverter) in
            do {
                let user = try typeConverter.convertFromWireType(obj: args[0], targetType: String.self)
                let message = try typeConverter.convertFromWireType(obj: args[1], targetType: String.self)
                self.handleMessage(message, from: user)
            } catch {
    private func handleMessage(_ message: String, from user: String) {
        // Do something with the message.


There are several sample projects in the Examples folder. They include:

  • SignalRClient.xcworkspace

    An Xcode workspace that has compiled libraries for macOS (OSX) and iOS, along with the Application targets 'ConnectionSample', 'HubSample', and 'HubSamplePhone'.

  • TestServer

    A .Net solution that the unit tests can be run against.

    The TestServer Requires .NET Core SDK 2.1.300 or later.

    To run, navigate to the TestServer folder and execute the following in the terminal:

    npm install
    dotnet run
You can’t perform that action at this time.
