swiftChoosing Swift Actors Over DispatchQueue for Thread-Safe State
Use Swift actors for mutable shared state in new code targeting iOS 15+/macOS 12+. Actors provide compile-time data-race isolation; DispatchQueue only serializes at runtime and deadlocks easily. Includes decision criteria, comparison table, trade-offs, and a verified Counter actor implementation.
Quasar Fibers vs Platform Threads: A JVM Concurrency Decision Guide
Decide when Quasar fibers fit your JVM concurrency needs, with constraints, trade-offs, and an unverified implementation pattern.
quasarPreventing Data Races in Swift with Actors and Structured Concurrency
Learn how to eliminate data races in Swift using Actors, @MainActor, and structured concurrency to manage shared state safely in asynchronous environments.
Managing State in Swift: Balancing Actors and Structured Concurrency
Learn how to combine Swift Actors and Structured Concurrency to eliminate data races in network-heavy applications while maintaining efficient resource management.
Managing State Consistency with Swift Actors and Reentrancy
Learn how to prevent data races and handle actor reentrancy in Swift. This guide covers the Isolated State pattern, Sendable boundaries, and strict concurrency verification.
Eliminating Data Races with Swift Actors
Stop fighting data races with manual locks. Learn how Swift actors use actor isolation and Sendable checks to provide compile-time thread safety for shared mutable state.
Architecting Shared State with Swift Actors
Learn how to implement Swift Actors to eliminate data races. This guide covers actor isolation, the Sendable protocol, and the critical risks of actor reentrancy in concurrent systems.
Stopping the Race: Using Swift Actors for Shared Mutable State
Stop chasing non-deterministic data races. Learn how Swift Actors replace manual locking with compile-time isolation to protect shared mutable state.
