Swift Package Index

We’re excited to announce that Swift Package Index has joined Apple. Swift Package Index has become the place developers rely on to discover and evaluate Swift packages. Bringing Swift Package Index to Apple allows us to build on its strong foundations while preserving its vision and expertise. Together, we’re building a comprehensive package registry to serve the Swift community’s evolving needs.

Our Commitment to the Swift Ecosystem

As Swift continues to grow, we believe the ecosystem needs a robust and comprehensive package registry: one that developers can trust for discovery, security, and reliability. Earlier this year, Swift Package Index reached a milestone of over 10,000 Swift packages indexed. This new chapter allows us to build on that foundation while preserving what makes it valuable today.

Swift Package Index automatically tests every Swift package across supported platforms and Swift versions, giving developers confidence before adding a dependency. We’ll continue supporting multi-platform package testing, and expanding that coverage as Swift grows. We launched with macOS, iOS, tvOS, watchOS, and Linux testing and later added support for visionOS, WebAssembly and Android. Last year alone, we processed over 3.5 million compatibility builds across all tested platforms.

With Apple's support, we're able to invest deeply in helping developers make better decisions about their package dependencies. operate at greater scale, and take on the next set of challenges with confidence.

What This Means for the Community

Swift Package Index has always had a close relationship with the package community, and we’ll continue to openly collaborate as the index evolves.

For developers and package consumers: Swift Package Index will continue to operate as it does today. You can continue to rely on it to discover packages, check compatibility, and explore documentation. As we embark on this new phase, our goal is to accelerate development and introduce new features that make discovering and evaluating packages even better.

For package authors: There are no immediate changes in how your packages are indexed or presented, or how your documentation is hosted: we’re committed to serving package authors and ensuring your work reaches the Swift community. Over time, we plan to introduce new capabilities around areas like package signing and identity to add robustness and security to the ecosystem.

For contributors: Swift Package Index will remain open source. The community’s source code contributions have been invaluable, and we want that to continue. Apple engineers will be contributing alongside the community as we build new features and improvements.

Looking Ahead

Over the coming months, we'll begin to share our plans for the evolution of the Swift Package Index. We’re excited about the opportunities this creates to enhance the experience for both package consumers and authors.

Our connection to the community of package developers has always been important to us, and we’ll continue sharing updates on the Swift Package Index blog.

We’re grateful to everyone who has contributed to Swift Package Index and to the broader Swift package ecosystem thus far. Your work makes Swift better for everyone, and we’re excited to work together with the community on our future plans.
