About Swift Syntax
Swift Syntax is a free, browser-based utility designed to make developer and design work as quick and frictionless as possible. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. It is one of about a hundred developer tools that share the same philosophy: do one thing, do it well, get out of your way.
