Searching Database…

What is this?This is the Swift Evolution repository: it tracks how the Swift programming language, its standard library, and its package manager evolve, one proposal at a time.
Is this something I install, or just documents to read?Just documents — it's a collection of proposals for changes and enhancements to Swift, plus release notes and a version changelog. There is nothing to install or run.
Does the repository only cover upcoming changes?No — the changelog documents past releases back to Swift 2.2, announced in January 2016, while new proposals describe enhancements for versions still in flight, like Swift 6.4.
Does the repo say where Swift is heading next?Yes — it maintains a Goals and Release Notes section listing the Swift language focus areas heading into 2025.
Is the content free to reuse?Yes — the repository is Apache-2.0 licensed, so the proposals and documentation can be reused freely, including in commercial projects.
