protocol AppUnionValue : TypeDisplayRepresentable

A protocol that provides nominal type identity and metadata for union values. Union values conforming to this protocol can be used as Shortcuts parameters with rich metadata support, enabling appropriate picker UI and parameter summaries. The `@UnionValue` macro automatically generates conformance to this protocol. You can provide custom metadata by implementing the protocol requirements in an extension. Example: ```swift @UnionValue enum Reaction { case tapback(Tapback) case text(String) } extension Reaction { static var typeDisplayRepresentation: TypeDisplayRepresentation { "Reaction" } static let caseDisplayRepresentations: [Cases: DisplayRepresentation] = [ .tapback: "Tapback", .text: "Text Reaction" ] } ```
