The default presentation sizing, appropriate for the platform.

## Declaration

static var automatic: AutomaticPresentationSizing { get }
```

## Discussion

Discussion On macOS, .automatic resolves to .form.fitted(horizontal: false, vertical: true). On all other platforms, including Mac Catalyst, it resolves to .form. note: AutomaticPresentationSizing
