Quick reference

What is Swift?

Swift is a high-performance system programming language. It has a clean and modern syntax, offers seamless access to existing C and Objective-C code and frameworks, and is memory safe by default.

Although inspired by Objective-C and many other languages, Swift is not itself a C-derived language. As a complete and independent language, Swift packages core features like flow control, data structures, and functions, with high-level constructs like objects, protocols, closures, and generics. Swift embraces modules, eliminating the need for headers and the code duplication they entail.

How to use this image

Start a REPL

Swift requires a little bit of extra security privilege to run the REPL. The following command creates an ephemeral container, attaches your terminal to it and starts the Swift REPL. A great way to try out pre-release builds!

docker run --cap-add sys_ptrace -it --rm swift swift
Pull the Docker Image From Docker Hub:
docker pull swift
Create a Container from the Image and Attach It:
docker run  -it --name swiftfun swift /bin/bash
To Start and Attach Your Image Later:

Start your image with name swiftfun

docker start swiftfun

and then attach it

docker attach swiftfun

Image Variants

The swift images come in many flavors, each designed for a specific use case.

swift:<version>

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.

Some of these tags may have names like bionic or xenial in them. These are the suite code names for releases of Ubuntu and indicate which release the image is based on.

swift:<version>-slim

This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run swift. Unless you are working in an environment where only the swift image will be deployed and you have space constraints, we highly recommend using the default image of this repository.
