Swift Registry: Dependencies Outside of GitHub

The Swift Package Manager (SwiftPM) enables Swift projects to directly depend on libraries available on GitHub. This feature previously required third-party tools like Carthage or CocoaPods for dependency management. However, SwiftPM has limitations. Dependencies must be either globally available on GitHub or stored on a local file system path. It doesn’t support distributing versioned packages outside of GitHub. To address this gap, Swift introduced the Swift Package Registry Specification (SE-0292) through an Evolution proposal. This specification outlines the means of publishing and distributing versioned Swift Packages through a Registry. Initially released in Swift 5.7 and Xcode 14, it provides a solution for this limitation. This talk will delve into the capabilities and workflows of Swift registries and explore scenarios where its adoption would be beneficial. It will demonstrate the specification through an open-source reference implementation developerd by the author.
