# init(_:as:using:widget:timelineProvider:) Creates a preview of a widget with an `INIntent` configuration. ``` @MainActor init(_ name: String? = nil, as family: WidgetFamily, using intent: Provider.Intent, widget: @escaping () -> some Widget, timelineProvider: @escaping () -> Provider) where Provider : IntentTimelineProvider ``` ## 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. --- Copyright © 2026 Apple Inc.
