BitTorrentSwift

A Swift implementation of the BitTorrent protocol, with very simple example iOS app.

Introduction

This is a working implementation of the basic BitTorrent protocol. Still a work in progress with many features/optimisations/fixes needed, but for now it works! 🎉

I decided to write this because I found it a interesting a challenging way to practise my iOS, it was a lot of fun to write, and to demonstrate how I write code.

What can it do today?

• It can download a torrent from other seeds/peers given a valid .torrent file.
• It will also seed (upload) to other peers which connect.

What is being worked on at the moment?

• Implementation of the DHT protocol (to enable trackerless torrents, and the ability to start a torrent via a magnet link)
• Dropping non-responsive and redundant peers
• Implementing an algorithm to speed up downloading the last bits.

Things for future

• Make a nice app with a more useful UI as the example app
• Replace the socket library for one written in pure Swift to make this a pure swift codebase
