How to run a .reality file in Swift Playgrounds

Reality Files can be opened with the RealityKit framework: you can load them by calling try Entity.load(named: "MyFile") or another variation of this function.

It still does not work, I get errors with the code below: `import RealityKit

struct Content: View {    var body: some View {      Entity.load(named: "RealityView")   } }`

The load(named:in:) function returns an Entity, and Entity does not conform to View, so it is not valid as the return value of a ViewBuilder, and results in a compile-time error.

Typically, you add entities into an ARView's Scene, which RealityKit renders. Note however that ARView is a UIView/NSView, and also does not conform to SwiftUI.View. To use ARView in SwiftUI, you can wrap it in a representable container. As a starting point, I recommend that you create a new project in Xcode that uses the "Augmented Reality App" template, and that you specify SwiftUI as the Interface, and RealityKit as the Content Technology.
