Plans are afoot to outfit Apple’s Swift language with a “first-class” concurrency model. The goal is to make concurrent programming in Swift efficient, safe, and convenient, according to the roadmap published at forums.swift.org.
Swift concurrency is intended to prevent data races on mutable state by default, through the implementation of asynchronous functions and actors. These will be introduced in two phases, first by bringing in the ability to create async functions and actors, and then by enforcing full actor isolation.
