init(_:as:using:widget:contentStates:)

Declaration

@MainActor init<Attributes>(_ name: String? = nil, as viewKind: ActivityPreviewViewKind, using attributes: Attributes, widget: @escaping () -> some Widget, @PreviewActivityBuilder<Attributes> contentStates: @escaping @MainActor () async -> [Attributes.ContentState]) where Attributes : ActivityAttributes

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 instantiate a Preview directly.
