Swift 5.6 introduces type system enhancements like type placeholders and explicit existential types with the any keyword, improves pointer interactions with temporary buffers and relaxed diagnostics, and refines concurrency safety by suppressing Sendable diagnostics by default.

The Swift Package Manager adds extensible build tools and command plugins for custom actions like code generation, alongside better dependency resolution and security through trust-on-first-use validation. Swift-DocC now integrates as a SwiftPM plugin, supports static hosting on platforms like GitHub Pages, and can document executable targets.
