Using Unity as a library (uaal) with AR Foundation?

I am currently doing some prototyping with AT using native code with Swift & SceneKit & also with AR Foundation & C# using Unity in iOS.

I would really like to see some examples of doing something more complex with using Unity as a library (uual) with iOS & Android. Going into the details on how to configure a project with Xcode and possibly share data between the native code & Unity game engine.

I’m asking the question here as it would be great if there are any plans for update the current book with such sections - one can hope :grinning:.
