how does swiftui state management work with the new observation framework

SwiftUI state management is enhanced by the new observation framework, which helps in efficiently managing dependencies and state changes within your app. In SwiftUI, views are state-driven, meaning that when your view's state changes, SwiftUI automatically updates the UI to reflect those changes. This is achieved by maintaining a representation of the user interface behind the scenes and updating it as data changes.

SwiftUI provides several tools for state management, including @State and @Binding. @State is used to create a new internal source of data for a view, allowing SwiftUI to manage the storage and provide it back for the view to read and write. @Binding creates a two-way reference to the state of another view, enabling synchronization between different parts of your UI.

The observation framework in SwiftUI allows you to establish dependencies between views and the data they use. For example, if a view depends on a specific property of an observable object, SwiftUI will automatically update the view when that property changes. This is demonstrated in the session "SwiftUI essentials," where a pet object is observed, and any changes to its properties trigger updates in the views that depend on it.

For more detailed information, you can refer to the session SwiftUI essentials (09:43) where these concepts are discussed.
