To attach a view to a tracked object in visionOS, you can use the object tracking capabilities provided by the platform. Here's a general approach based on the sessions from WWDC:

  1. Create a Reference Object: First, you need to create a reference object for the item you want to track. This involves using a 3D model of the item in USDZ format and training a machine learning model using CreateML's spatial object tracking feature. This process is detailed in the session Explore object tracking for visionOS.

  2. Anchor Virtual Content: Once you have your reference object, you can anchor virtual content to it. This involves using RealityKit and ARKit APIs to place content relative to the tracked object. You can define SwiftUI elements in the attachments section under Reality View and add them as child nodes to the anchor entities. This is explained further in the session Explore object tracking for visionOS.

  3. Use Object Tracking API: The new object tracking API in visionOS allows you to attach content to individual objects found around the user. This functionality is highlighted in the Platforms State of the Union.

By following these steps, you can effectively attach views to tracked objects in visionOS, enhancing the interactivity and immersion of your app.
