# init(rootView:) A RealityKit component that manages a SwiftUI view hierarchy. ``` init(rootView: Content) where Content : View ``` ## Discussion Create a `ViewAttachmentComponent` component when you want to integrate SwiftUI views into a RealityKit entity hierarchy. At creation time, specify the SwiftUI view you want to use as the root view for this component; you can change that view later by creating a new component with a new root view and replacing the old component with the new one. Use `ViewAttachmentComponent` like you would any other component, by assigning it on an entity and adding that entity to your scene using a [`RealityView`](/documentation/RealityKit/RealityView). --- Copyright © 2026 Apple Inc.
