RealityView and Persistent World Data?

I was watching the Developer videos, and there was mention that RealityView handles persistent world data differently and also automatically for us.

I am having an issue finding the material I need to get up to speed on that.

In ARKit, I was able to place a model with the world data and recall that .map data. It even stored a reference image for the scene to help match the world data.

I'm looking for the information on how to implement and work with those same features with RealityView, as it seems to be better/automatically integrated?

I need help being pointed in the right direction. Sample code would be amazing.

I wanted to update this post with resources I found.

It appears the automation for persistent anchors and world data maps has been configured as WorldAnchors. Currently, it looks like this is only supported in visionOS.

It appears that by simply adding a WorldAnchor that visionOS automatically tracks the world map, unloading and loading based on your location automatically in the background. This is amazing.

Though, I'm not sure why this wouldn't be supported on iOs and iPadOS as well. Perhaps in the future it will be implemented as a core ARKit feature as well.

To the best of my limited knowledge, it appears we will have to continue to use the previous methods for persistent data, which can be found here:

https://developer.apple.com/documentation/arkit/arkit_in_ios/data_management/saving_and_loading_world_data

However, I still have to try and implement this with RealityView. As it is my understanding that only RealityView supports Reality Composer Pro packages.

The goal here is to simply place a Reality Composer Pro package with AR Persistence...
