Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but Gradient Progress Bar does support its use on supported platforms.

Once you have your Swift package set up, adding Gradient Progress Bar as a dependency is as easy as adding it to the dependencies value of your Package.swift.
