@MainActor struct Preview

A base type that preview macros use to create previews. Frameworks like SwiftUI and WidgetKit define initializers for this type, along with framework-specific preview macros that rely on this type. You don't use this type directly. Instead, use one of the preview macros, like <doc://com.apple.documentation/documentation/SwiftUI/Preview(_:body:)>.
