How does the new @Entry macro work?

The new @Entry macro in SwiftUI simplifies the process of adding new values to SwiftUI's keyed storage types, such as environment values, focus values, and the new container values. Instead of writing a full conformance to EnvironmentKey and an extension on EnvironmentValues, you can now use the @Entry macro to declare a property directly. This macro provides a convenient syntax for adding these values, making it easier to work with SwiftUI.
For example, you can use the @Entry macro to create a new container value by declaring a property within an extension on the ContainerValues type. This property can then be used to store and track specific values, such as a boolean to indicate if a card has been rejected. Additionally, you can create custom view modifiers to set these properties, enhancing the customization capabilities of your SwiftUI containers.
To learn more about the @Entry macro and its applications, you can refer to the session Demystify SwiftUI containers (14:45).
