Swift Concurrency Migration Guide

The complete content of the Swift Concurrency Migration Guide by Apple. This guide helps you migrate your code to take advantage of Swift's data-race safety guarantees and the Swift 6 language mode.

Documentation

Data Race Safety (Guide/DataRaceSafety.md): Learn about the fundamental concepts Swift uses to enable data-race-free
Migration Strategy (Guide/MigrationStrategy.md): Get started migrating your project to the Swift 6 language mode.
Enable data-race safety checking (Guide/EnableDataRaceSafety.md): Use Swift 6 to get full data-race safety checking or add checking to an existing Swift 5 project.
Common Compiler Errors (Guide/CommonProblems.md): Identify, understand, and address common problems you can encounter while
Incremental Adoption (Guide/IncrementalAdoption.md): Learn how you can introduce Swift concurrency features into your project
Migrating to upcoming language features (Guide/FeatureMigration.md): Migrate your project to upcoming language features.
Source Compatibility (Guide/SourceCompatibility.md): See an overview of potential source compatibility issues.
Library Evolution (Guide/LibraryEvolution.md): Annotate library APIs for concurrency while preserving source and ABI
Runtime Behavior (Guide/RuntimeBehavior.md): Learn how Swift concurrency runtime semantics differ from other runtimes you may

Code Examples

Swift source files demonstrating migration patterns and concurrency concepts:

Boundaries.swift (Examples/Boundaries.swift): Example code demonstrating Boundaries.
ConformanceMismatches.swift (Examples/ConformanceMismatches.swift): Example code demonstrating ConformanceMismatches.
DispatchQueue_PendingWork.swift (Examples/DispatchQueue_PendingWork.swift): Example code demonstrating DispatchQueue PendingWork.
Globals.swift (Examples/Globals.swift): Example code demonstrating Globals.
IncrementalMigration.swift (Examples/IncrementalMigration.swift): Example code demonstrating IncrementalMigration.
PreconcurrencyImport.swift (Examples/PreconcurrencyImport.swift): Example code demonstrating PreconcurrencyImport.
main.swift (Examples/main.swift): Example code demonstrating main.

Usage Notes

Start with Data Race Safety to understand the core concepts
Follow the Migration Strategy for a recommended approach
Refer to Common Problems for solutions to typical issues
Use the Code Examples as reference implementations
