This document discusses using Unity and ARInterface to enable cross-platform AR development. It recommends starting with Unity3D to write code once and deploy to both ARKit and ARCore platforms. It also provides sample code links and specifications for ARKit and ARCore, warning of version requirements needed to use ARCore plugins from Unity.
