 ## Key features
 
-- **Control of Unity view** as a SwiftUI element that can be repositioned and resized. Unity's [documentation](https://docs.unity3d.com/2022.3/Documentation/Manual/UnityasaLibrary-iOS.html) says "Unity as a Library only supports full-screen rendering, and doesn’t support rendering on part of the screen." We have fixed this limitation.
-- **Touches and gestures** on Unity view are processed within Unity.
-- **Restarting** the Unity player.
-- **State data** is sent from native Swift to Unity C# as a struct with members including string, boolean, floating point, integer, and MTLTexture types.
