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.

Exercism is a great website

What I like about it is that I am able to solve the challenges in a TDD way working in a environment that I am familiar (my own PC not a browser IDE) and the cherry on the top of the cake is that I have access to code reviews.

Relaxed. Encouraging. Supportive.

I've built a couple of iOS apps in Swift, and love the syntax. It truly is my favorite strongly-typed language to work in. I'm excited to share what I've learned, and learn alongside others!

I love swift! I've been an iOS developer since iOS 3 and developing in Swift for over 2 years now at a large iOS company. I love the community surrounding swift, everyone has been so supportive. I'm hoping to help the developers grow and learn somethings myself along the way as well.

I love Swift for the new approach it gives to iOS development. I started using Swift when 1.0 was announced, excited to help developpers learn this super fun language!

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 started programming with Java, then moved to Scala, and later ended up in iOS development with Objective-C and Swift. I'm happy to help newcomers from all disciplines.

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.
Fun. Challenging. Interesting
