Apps generally don’t work that way. You would need to link the ARKit framework into your project. Corona does not support ARKit directly, someone would need to develop a plugin to do this, or you can use Corona Native (Xcode builds) instead of Simulator builds and attempt to access ARkit.
Now depending on what you’re trying to do, you can create a display.newRect() and fill it with video today, with standard Corona (iOS devices only, not supported on Android). We had a developer build a pokemon go type game with Corona.
