Perfect is a complete and powerful toolbox, framework, and application server for Linux, iOS, and macOS (OS X). It provides everything a Swift engineer needs for developing lightweight, maintainable, and scalable apps and other REST services entirely in the Swift programming language for both client-facing and server-side applications.

Perfect includes a suite of tools that will enhance your productivity as you use only one programming language to build your apps: Swift. The global development community’s most dynamic and popular server-side toolbox and framework available today, Perfect is the backbone for many live web applications and apps available on iTunes.

This guide is designed for developers at all levels of experience to get Perfect up and running quickly.

The master branch of this project currently compiles with Xcode 11 or the Swift 5 toolchain on Ubuntu.
