To successfully migrate your app to Swift 6, there are several key steps and considerations you should follow:
-
Enable Complete Concurrency Checking: Start by enabling complete concurrency checking on a per-module basis. This allows you to identify and resolve potential data races while still in Swift 5 mode. This step is crucial for preparing your code for Swift 6's enforced data isolation.
-
Resolve Warnings: Address all warnings related to concurrency issues. The Swift compiler will guide you by pointing out potential bugs, acting like a pair programmer.
-
Enable Swift 6 Mode: Once all warnings are resolved for a module, enable Swift 6 mode. This locks in your changes and prevents future regressions to unsafe states.
-
Incremental Migration: Migrate your app incrementally, one module at a time. This approach allows you to manage the transition smoothly without waiting for all dependencies to migrate.
-
Adopt New Language Features: Take advantage of Swift 6's new language features, such as data race safety, which is opt-in. This feature helps prevent accidental sharing of state between tasks and actors, improving the quality of your app by catching concurrency mistakes at compile time.
-
Refactor and Optimize: After enabling Swift 6 mode, consider refactoring your app to optimize for the new concurrency model and undo any unsafe opt-outs.
For a detailed walkthrough, you can refer to the session Migrate your app to Swift 6 (07:17) which provides a step-by-step guide on the migration process. Additionally, the session Platforms State of the Union (27:44) discusses the broader context of Swift 6 and its new features.

What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
