Deep Dive into Swift Actors

Building modern Swift applications often means bridging Swift Concurrency with legacy queue-based and callback APIs. This session explores actors beyond the basics, examining their power and pitfalls when integrating with existing codebases. Drawing from real-world macOS SDK development, this talk covers advanced patterns for making actors work alongside traditional concurrency primitives.

What you’ll learn:
– Using custom executors to run actors on specific dispatch queues
– When and how to combine Mutexes and Locks with actors for both safety and ergonomic APIs
– Practical strategies for wrapping callback-based APIs in actor-isolated code
– Understanding how Swift 6’s approachable concurrency changes affect actor design

Aimed at developers who understand and use Swift Concurrency features and want to master the nuances in production code.
