# InterfaceOrientation

The orientation of the interface from the user’s perspective.

## Declaration

```swift
struct InterfaceOrientation
```

## Overview

Overview By default, device previews appear right side up, using orientation portrait. You can change the orientation with a call to the previewInterfaceOrientation(_:) modifier: struct CircleImage_Previews: PreviewProvider {     static var previews: some View {         CircleImage()             .previewInterfaceOrientation(.landscapeRight)     } }
