Macros

The following macros are available globally.

  • This macro provides conformance of the CaseIterable protocol to enums, including those with associated values.

    In the example below, applying @AutoCaseIterable to this enum provides automatic CaseIterable conformance, even though these cases have associated values.

    @AutoCaseIterable
enum UserInteractions: UserInteractionTypeable {
   case sliderInteraction(value: Double)
   case modeButton(mode: Mode)
 }

    Declaration

    Swift

    @attached(extension, conformances: CaseIterable, names: named(allCases)
) public macro AutoCaseIterable() = #externalMacro(module: "AutomaticEnumCaseIterableMacro", type: "AutomaticEnumCaseIterableMacro")
