SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Swift 6.2 introduces a default isolation model for concurrency; this skill helps teams migrate safely by explaining when to use MainActor default inference, isolated conformance, and explicit @concurrent for real parallelism, reducing data-race risks.

Core Features & Use Cases

  • Isolated conformances to safely adopt non-isolated protocols on MainActor types
  • MainActor default inference to reduce boilerplate and migration effort
  • Explicit @concurrent usage for CPU-intensive work with safe offloading
  • Guidance on protecting global/static mutable state
  • Step-by-step migration recommendations and best practices for app targets
  • Use cases include migrating existing Swift codebases and designing MainActor-centric architectures

Quick Start

Enable MainActor default inference in your app and begin migrating hot paths to explicit concurrency patterns.

FAQPage Schema
How do I migrate to Swift 6.2 concurrency without causing data races?

Migrate to Swift 6.2 concurrency by enabling MainActor default inference to reduce boilerplate, applying isolated conformances for protocols, and adjusting build settings step by step to eliminate data-race risks.

What is MainActor default inference in Swift 6.2?

MainActor default inference is a Swift 6.2 concurrency model that defaults to isolating state on the MainActor, significantly reducing migration boilerplate and preventing data races across your app target.

When should I use explicit @concurrent for CPU-intensive work in Swift?

Use explicit @concurrent in Swift 6.2 when offloading CPU-intensive work to achieve real parallelism, safely bypassing MainActor isolation without introducing data races into your architecture.

How do I adopt non-isolated protocols on MainActor types in Swift 6.2?

Adopt non-isolated protocols on MainActor types by using isolated conformances, a Swift 6.2 concurrency pattern that safely satisfies protocol requirements while maintaining strict state isolation.

Does migrating to Swift 6.2 concurrency require protecting global mutable state?

Yes, migrating to Swift 6.2 concurrency requires protecting global and static mutable state using MainActor isolation or explicit concurrency features to ensure data-race safety across your codebase.

What are the limitations of MainActor default inference for app targets?

MainActor default inference limits real parallelism for CPU-intensive tasks; it reduces data-race risks but requires explicit @concurrent usage to safely offload heavy workloads off the main thread.
