Binding to components in SwiftUI and RealityKit refers to the ability to connect SwiftUI views and RealityKit entities in a way that allows for dynamic updates and interactions. This integration enables developers to use SwiftUI's declarative syntax to manage and update RealityKit components, such as animations and gestures, directly from SwiftUI code.
In the session Better together: SwiftUI and RealityKit, it is explained that RealityKit entities can now act like model objects to drive updates to your SwiftUI views, allowing information to flow both ways between SwiftUI and RealityKit. This means you can bind SwiftUI views to RealityKit components, enabling seamless updates and interactions between the two frameworks.
Additionally, RealityKit entities are now observable, which means changes in their state can be directly reflected in SwiftUI views. This integration simplifies the process of creating rich, interactive 3D experiences by leveraging the strengths of both SwiftUI and RealityKit.
