Apple formally contributed the code of Swift Build to GitHub on February 1. The repository contributed by Apple also includes support for Windows and Linux, alongside Apple’s platforms.
Build systems take the code the programmer writes and turn that work into standard components like libraries and command-line tools used to create working applications. Currently, Swift offers two different build managers, which the Swift team identified as a source of developer issues.
