Observable

Observable objects and data-race safety are key topics discussed in the context of Swift 6 and SwiftUI. Here are some relevant points from the sessions:

1. Migrate your app to Swift 6:

   • The session discusses how to handle observable objects in SwiftUI, particularly when dealing with concurrency and actors. For example, if you have a SwiftUI observable object and a save operation on another actor, you need to ensure that the data being shared between these actors is sendable to avoid data races. This is crucial when the main actor and another actor could access shared mutable state simultaneously (Migrate your app to Swift 6).
   • The session also covers how to handle global variables and instances to ensure they are safe from data races by using actors or marking them as sendable (Migrate your app to Swift 6).

2. A Swift Tour: Explore Swift’s features and design:

   • This session explains the importance of avoiding data races and how Swift 6 ensures data-race safety at compile time. It introduces the concept of sendable values, which protect their state from concurrent accesses, and discusses how actors can be used to encapsulate shared mutable state safely (A Swift Tour: Explore Swift’s features and design).

3. Track model changes with SwiftData history:

   • This session highlights how SwiftData history can be used to track changes in your data store over time, which is useful for maintaining data consistency across different parts of your app, such as when dealing with observable objects (Track model changes with SwiftData history).
