how to create realityKit view for iOS app that displays cube on horizontal plane?

To create a RealityKit view for an iOS app that displays a cube on a horizontal plane, you can follow these general steps:

1. Set Up RealityKit: Ensure you have imported RealityKit and ARKit in your project. RealityKit is used for rendering 3D content, while ARKit helps with tracking and anchoring.

2. Create an ARView: This is the view that will display your RealityKit content. You can add it to your view hierarchy in your storyboard or programmatically.

3. Configure ARSession: Set up an AR session with a configuration that supports horizontal plane detection. This will allow you to anchor your cube to a detected plane.

4. Create a Cube Entity: Use RealityKit to create a 3D cube entity. You can customize its size, color, and material.

5. Anchor the Cube: Once a horizontal plane is detected, create an anchor entity and add your cube entity to it. This will position the cube on the plane.

6. Run the ARSession: Start the AR session to begin detecting planes and rendering your cube.

For more detailed guidance, you can refer to the session Build a spatial drawing app with RealityKit (02:43) which covers setting up spatial tracking and anchoring in RealityKit. This session provides insights into using RealityKit's spatial tracking APIs, which are essential for detecting and interacting with real-world surfaces.
