How to manage state

To manage state in the context of Apple's WWDC sessions, there are several approaches depending on the technology or framework you are using:

Core ML: In the session Deploy machine learning and AI models on-device with Core ML, it is discussed how Core ML now supports stateful models. This allows you to manage state more efficiently by using Core ML states instead of handling key-value caches manually. This can reduce overhead and improve inference efficiency.
SwiftUI: In the session SwiftUI essentials, SwiftUI provides a way to manage state using the @State property wrapper. This allows SwiftUI to manage the storage of the state and provide it back for the view to read and write. A @Binding can be used to create a two-way reference to the state of another view, allowing for dynamic updates and interactions.
Core Spotlight: In the session Support semantic search with Core Spotlight, client state is used to manage large catalogs of items and maintain data integrity between your app and Spotlight. This helps in preventing over-donation of items and ensures that your searchable content stays up to date.

These sessions provide insights into different ways of managing state across various Apple technologies, each tailored to specific use cases and frameworks.
