The concept of "state" is discussed in various contexts during Apple's WWDC sessions. Here are some highlights:

  1. SwiftUI Essentials: In the session "SwiftUI essentials," state management is a key topic. SwiftUI uses state to manage the internal data of a view, allowing it to update dynamically. A view property marked as @State is managed by SwiftUI, which handles the storage and provides it back for the view to read and write. This is crucial for creating interactive and dynamic user interfaces. SwiftUI essentials

  2. Core ML and Stateful Models: In the session "Deploy machine learning and AI models on-device with Core ML," the concept of state is introduced in the context of machine learning models. Stateful models retain history from previous inputs, which can be beneficial for tasks like language modeling. Core ML now supports stateful models, allowing for more efficient handling of state without manually managing inputs and outputs. Deploy machine learning and AI models on-device with Core ML

  3. Concurrency and State Management: In the session "Code-along: Elevate an app with Swift concurrency," managing state in concurrent environments is discussed. Swift's concurrency model provides tools to safely manage mutable state, such as using the main actor to protect state from concurrent access. This helps prevent data races and ensures thread safety.

These sessions provide insights into how state is managed across different technologies and frameworks presented at WWDC, highlighting its importance in building responsive and efficient applications.
