Swift Package Manager is a package manager for the Swift programming language that handles dependency management, versioning, and distribution of Swift code.
The tool addresses the core challenges of compiling and linking Swift packages by providing integrated dependency resolution and version management. It includes a build system capable of building for macOS and Linux, with Xcode integration starting from version 11 that extends support to iOS, watchOS, and tvOS applications. The system is designed to work with services like GitHub for public package sharing while also supporting private development, team collaboration, and custom distribution models at any granularity.
Developers should adopt this tool if they are working within the Swift ecosystem and need to manage dependencies or distribute Swift code. It is the standard package manager for Swift and comes integrated with the Swift toolchain and Xcode, making it the natural choice for any Swift project. The tool is particularly suited for projects targeting Apple platforms or Linux, and it provides both command-line and IDE integration through Xcode. The project also exposes libSwiftPM, which enables Language Server Protocol support through SourceKit-LSP for editor integration beyond Xcode.
Development activity shows consistent engagement with the project's infrastructure and tooling. The codebase receives regular updates to its build system integration and dependency resolution logic. Contributions follow established policies documented in a contributor guide, with a development environment setup process for those wanting to work on the package manager itself. The project maintains active documentation covering package creation, manifest APIs, and release notes documenting changes between versions.
