If you consider something needs to be implemented, just open an issue or make a PR


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 client.read(&buffer, 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 'https://github.com/CocoaPods/Specs.git'
target '<Your Target Name>' do
    pod 'Socket.swift', '~> 2.2'

Then, run the following command:

$ pod install

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: "https://github.com/BiAtoms/Socket.swift.git", majorVersion: 2)


Just drag and drop the files in the Sources folder.
