Creates a preview of an NSViewController.
Declaration
@MainActor init(_ name: String? = nil, traits: PreviewTrait<Preview.ViewTraits>..., body: @escaping @MainActor () -> NSViewController)Discussion
The #Preview macro expands into a declaration that calls this initializer. To create a preview that appears in the canvas, you must use the macro, not call this initializer directly.
