How do you use Unity on visionOS?

To use Unity on visionOS, you can follow these steps:

Start with a Compatible App: Begin by running your game as a compatible app on visionOS. This involves compiling the app with the iOS SDK and running it on visionOS as a compatible app. Compatible apps will run in a window on visionOS, and both touch controls and game controllers are available, providing a uniform experience across all platforms.
Convert to a Native App: To convert the app to a native visionOS app, go to the build settings of the app and select the iOS target. Add Apple Vision as a supported destination to compile the app. You might encounter a few compilation errors, but if the app was made for iOS, most of the code should compile.
Rendering Options: For displaying the content of your game on visionOS, you have several options:
- Render to a CMTL Layer: This can be easily integrated into UIViews.
- Render Directly to a Relative Texture: Using the new low-level texture API for more control.
Enhance the Rendering: Start with a CM metal layer if it is easier, but it is recommended to move to a low-level texture to get the most control over the rendering.

These sessions provide a comprehensive guide on how to get started with visionOS and enhance your app for spatial computing.
