Swift Package Manager

Swift Package Manager The Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies. The Package Manager will be released with Swift 3 and is currently only available with the Swift 3 development snapshots. — Swift.org - Package Manager
