A convenience type alias for referring to a stack action of a given reducer’s domain.
typealias StackActionOf<R> = StackAction<R.State, R.Action> where R : ReducerInstead of specifying two generics:
case path(StackAction<Path.State, Path.Action>)You can specify a single generic:
case path(StackActionOf<Path>)import ComposableArchitectureThe Composable Architecture (TCA, for short) is a library for building applications in a consistent and understandable way, with composition, testing, and ergonomics in mind. It can be used in SwiftUI, UIKit, and more, and on any Apple platform (iOS, macOS, tvOS, and watchOS).
enum StackAction<State, Action>A wrapper type for actions that can be presented in a navigation stack.
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.
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.
Learn about stack-based navigation, that is navigation modeled with collections, including how to model your domains, how to integrate features, how to test your features, and more.
struct StackState<Element>A list of data representing the content of a navigation stack.
struct StackElementIDAn opaque type that identifies an element of StackState.
