which are the most relevant new visionOS features?

The most relevant new features in visionOS, as presented at WWDC, include:

1. Enhanced Scene Understanding: VisionOS now allows for more creative app experiences by letting developers decide if a user's hands appear in front of or behind content. The scene understanding capabilities have been significantly extended, with planes detectable in all orientations and the introduction of room anchors that consider the user's surroundings on a per-room basis. This also includes a new object tracking API that allows attaching content to individual objects around the user, enhancing interactivity.

2. Spatial Computing Opportunities: VisionOS is built on the foundation of macOS, iOS, and iPadOS, allowing developers to use common tools and frameworks like SwiftUI, RealityKit, and ARKit to create spatial apps. This integration provides opportunities for deeper interaction and understanding of the world around the user.

3. Enterprise APIs: A set of new enterprise APIs has been introduced to enhance collaboration, communication, and productivity in enterprise environments. These APIs support new spatial experiences and guided work activities, making complex tasks simpler and enabling entirely new spatial experiences.

4. Device Management Enhancements: VisionOS 2.0 extends management for Apple Vision Pro to support most MDM payloads, configurations, and commands, making it as easy to manage as an iPhone or iPad. This includes support for device and user enrollment, with transparent account management functions.

5. Guest User Feature: VisionOS includes a guest user feature that allows others to set up and try out Apple Vision Pro, preserving the owner's data and privacy.
