# SurfaceSnappingInfo

A type representing information about the window scenes snap state.

## Declaration

```swift
struct SurfaceSnappingInfo
```

## Overview

Overview Use the provided SurfaceSnappingInfo to modify the contents of your view. struct LightFixtureView: View {     @Environment(\.surfaceSnappingInfo)     var snappingInfo: SurfaceSnappingInfo

var body: some View {         if snappingInfo.isSnapped {             switch SurfaceSnappingInfo.authorizationStatus {                 case .authorized:                     switch snappingInfo.classification {                         case .table:                             LampView()                         case .floor:                             FloorLampView()                         default:                             DefaultLampView()                     }                 default:                     DefaultLampView()             }         } else {             FloatingOrbLampView()         }     } } The bottom of volumes may snap to horizontal surfaces and the back of windows may snap to vertical surfaces.
