# previews

A collection of views to preview.

## Declaration

```swift
@ContentBuilder @MainActor @preconcurrency static var previews: Self.Previews { get }
```

## Discussion

Discussion Implement a computed previews property to indicate the content to preview. Xcode generates a preview for each view that you list. You can apply View modifiers to the views, like you do when creating a custom view. For a preview, you can also use various preview-specific modifiers that customize the preview. For example, you can choose a specific device for the preview by adding the previewDevice(_:) modifier: struct CircleImage_Previews: PreviewProvider {     static var previews: some View {         CircleImage()             .previewDevice(PreviewDevice(rawValue: "iPad Pro (11-inch)"))     } } For the full list of preview-specific modifiers, see Previews in Xcode.
