An overload of Reducer that takes a description of protocol conformances to synthesize on the State and Action types

It can be used in SwiftUI, UIKit, and more, and on any Apple platform (iOS, macOS, tvOS, and watchOS).
@attached(member, names: named(State), named(Action), named(init), named(body), named(CaseScope), named(scope)) @attached(memberAttribute) @attached(extension, conformances: Reducer, CaseReducer) macro Reducer() Helps implement the conformance to the Reducer protocol for a type.
protocol Reducer<State, Action>A protocol that describes how to evolve the current state of an application to the next state, given an action, and describes what Effects should be executed later by the store, if any.
protocol CaseReducer<State, Action> : Reducer where Self.Action == Self.Body.Action, Self.Body : Reducer, Self.State : CaseReducerState, Self.State == Self.Body.StateA reducer represented by multiple enum cases.
struct _SynthesizedConformanceA description of a protocol conformance to synthesize on the State and Action types generated by the Reducer macro.
@attached(peer, names: named(`_`)) macro ReducerCaseEphemeral() Marks the case of an enum reducer as holding onto “ephemeral” state.
@attached(peer, names: named(`_`)) macro ReducerCaseIgnored() Marks the case of an enum reducer as “ignored”, and as such will not compose the case’s domain into the rest of the reducer besides state.
protocol CaseReducerStateA state type that is associated with a CaseReducer.
