It can be used in SwiftUI, UIKit, and more, and on any Apple platform (iOS, macOS, tvOS, and watchOS).
struct Scope<ParentState, ParentAction, Child> where Child : ReducerEmbeds a child reducer in a parent domain.
class WritableKeyPath<Root, Value>A key path that supports reading from and writing to the resulting value.
@dynamicMemberLookup struct AnyCasePath<Root, Value>A type-erased case path that supports embedding a value in a root and attempting to extract a root’s embedded value.
@resultBuilder enum ReducerBuilder<State, Action>A result builder for combining reducers into a single reducer by running each, one after the other, and merging their effects.
associatedtype StateA type that holds the current state of the reducer.
associatedtype ActionA type that holds all possible actions that cause the State of the reducer to change and/or kick off a side Effect that can communicate with the outside world.
