To adopt Swift 6 Concurrency while keeping Observable
, you can follow the guidance provided in the session "Migrate your app to Swift 6" from WWDC 2024. Here are the key steps and considerations:
-
Enable Swift 6 Language Mode: Start by enabling the Swift 6 language mode in your project settings. This will help you catch concurrency issues at compile time and ensure data-race safety.
- Migrate your app to Swift 6 (25:07)
-
Main Actor Isolation: If your
Observable
object interacts with the UI, you should isolate it to the main actor. This ensures that all its methods and property accesses are made on the main thread.- Migrate your app to Swift 6 (08:58)
-
Concurrency Annotations: Use concurrency annotations like
@MainActor
to specify the actor context for yourObservable
properties and methods. This helps the compiler enforce the correct execution context.- Migrate your app to Swift 6 (18:53)
-
Handling Protocols: When conforming to protocols, ensure that the protocol methods are compatible with actor isolation. You might need to use concurrency annotations on protocol methods to align with the actor context.
- Migrate your app to Swift 6 (25:07)
-
Refactor for Data Isolation: Refactor your code to use value types for communication between actors and avoid shared mutable state. This helps in maintaining data-race safety.
- Migrate your app to Swift 6 (01:52)
By following these steps, you can adopt Swift 6 Concurrency in your app while keeping your Observable
objects safe and efficient. For a detailed walkthrough, you can refer to the session "Migrate your app to Swift 6" from WWDC 2024.
