Swift 5.5 Released!

Swift 5.5 is now officially released! Swift 5.5 is a massive release, which includes newly introduced language capabilities for concurrency, including async/await, structured concurrency, and Actors. My heartfelt thanks to the entire Swift community for all the active discussion, review, and iteration on the concurrency (and other additions) that make up the release. Thank you!

Swift 5.5 is a major release introducing powerful concurrency features like async/await, structured concurrency, and Actors, alongside other enhancements.

Key updates include package collections for easier package discovery, extended property wrappers for functions, and Codable synthesis for enums with associated values, all shaped by the Swift Evolution process.

The release also improves interoperability with Objective-C, adds global actors, and supports task-local values and async sequences.
