swift state | Ask WWDC

At WWDC 2024, Apple introduced several updates related to the concept of "state" across different sessions. Here's a summary of the relevant content:

Core ML and Stateful Models:
- In the session Bring your machine learning and AI models to Apple silicon, Core ML introduced support for stateful models. This allows models to maintain state across different runs, which can be particularly useful for tasks that require memory of past inputs, such as accumulators. This feature automates the updating of state tensors, improving performance by eliminating the need to define them as inputs or outputs.
SwiftUI and State Management:
- In the session SwiftUI essentials, SwiftUI's state management was discussed. SwiftUI uses state to manage the internal data of a view, allowing for dynamic updates. A binding creates a two-way reference to the state of another view, enabling interactive UI components that respond to user input by updating the state and reflecting changes in the UI.
Swift 6 and Data-Race Safety:
- The session Migrate your app to Swift 6 highlighted improvements in data-race safety with the introduction of the Swift 6 language mode. This mode enforces data isolation, preventing accidental sharing of state between tasks and actors, which helps in reducing concurrency bugs and improving app stability.

These updates reflect Apple's focus on enhancing performance, safety, and ease of use in app development through improved state management and concurrency handling.
