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 %%IMAGE%% swift
Pull the Docker Image From Docker Hub:
docker pull %%IMAGE%%
Create a Container from the Image and Attach It:
docker run -it --name swiftfun %%IMAGE%% /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
