Swift

Join the Swift Track
Swift is a modern open-source language with the aim of making programming simple things easy, and difficult things possible while still being fast and safe by design. Swift can run in scripting mode in the included REPL or it can be compiled with full support for C and Objective-C interoperability.

About Swift

//
// HelloWorld.swift
//

struct HelloWorld {
    static func hello(_ text: String = "World") -> String {
        return "Hello, \(text)!"
    }
}

Swift is a modern open source programming language that runs on macOS, Linux and on Windows using a linux subsystem.

Swift was developed initially by Apple to interoperate with their key frameworks, Cocoa and CocoaTouch, both of which are mostly implemented in Objective-C.

Swift is influenced by a large number of existing programming languages, and it incorporates concepts from a wide range of programming methods. Everything from scripting to object oriented and functional programming.

Apple refers to Swift as a "protocol oriented programming language" and has expressed the goal of eventually making Swift useful for everything from scripts to an operating system.


This Swift Tour is an introduction the language on Apple's Public Developer Website.


Wikipedia's Swift Page giving a good, Wikipedia-styled overview.


Swift is documented in The Swift Programming Language - again, on Apple's Public Developer Website - and in the iBooks Store. The ePub version is also available on Swift.org.

A tremendous learning opportunity to explore the depth of your own knowledge

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.

Relaxed. Encouraging. Supportive.

Meet the Swift Track mentors

Once you join the Swift language track, you will receive support and feedback from our team of mentors. Here are the bios of a few of the mentors of this track.

I love Swift because of how simple and powerful the language is. I am constantly learning cool new ways of writing good Swift code as I work on an iOS app day to day.

I've been developing iOS apps since the iOS 3.0 days. I learned Swift when it first released with the help of exercism.io. I enjoy helping others learning the language, I always seem to learn a bit more myself.

I learned to program on embedded devices, and later moved to iOS development in Objective-C and Swift. Most recently, I've been exploring functional programming in Scala. I'm interested in security principles and applied cryptography. And if I can ever find some spare free time, I would love to try out Rust!

I have been programming for around 5 years using various languges and technologies. Currently, I focus on Swift and iOS development. I am excited to mentor for Swift and join Exercism's Objective-C track as a student!

I'm an experienced iOS Developer and used Swift in many projects. Swift is the most lovable programming language I've ever developed. For, it's so modern, incredibly fast and safe by design.
Fun. Challenging. Interesting
