let server = try Socket(.inet, type: .stream, protocol: .tcp) // create server socket
try server.set(option: .reuseAddress, true) // set SO_REUSEADDR to 1
try server.bind(port: 8090, address: nil) // bind 'localhost:8090' address to the socket
try server.listen() // allow incoming connections

let client = try Socket(.inet, type: .stream, protocol: .tcp) // create client socket
try client.connect(port: 8090) // connect to localhost:8090

let clientAtServerside = try server.accept() // accept client connection
let helloBytes = ([UInt8])("Hello World".utf8)
try clientAtServerside.write(helloBytes) // sending bytes to the client

var buffer = [UInt8](repeating: 0, count: helloBytes.count) // allocate buffer
let numberOfReadBytes = try, size: helloBytes.count)
print(numberOfReadBytes == helloBytes.count) // true
print(buffer == helloBytes) // true




CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate Socket.swift into your Xcode project using CocoaPods, specify it in your Podfile:

source ''
target '<Your Target Name>' do
pod 'Socket.swift', '~> 2.4.0'

Then, run the following command:

$ pod install


Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate Socket.swift into your Xcode project using Carthage, specify it in your Cartfile:

github "BiAtoms/Socket.swift" ~> 2.4.0

Run carthage update to build the framework and drag the built SocketSwift.framework into your Xcode project.

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but Socket.swift does support its use on supported platforms.

Once you have your Swift package set up, adding Socket.swift as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "", from: "2.4.0")


Just drag and drop the files in the Sources folder.
