A publisher that emits when state changes.
@MainActor var publisher: StorePublisher<State> { get }s22ComposableArchitecture5StoreC9publisherAA0C9PublisherVyxGvp What are these?6HXLCThis publisher supports dynamic member lookup so that you can pluck out a specific field in the state:
store.publisher.alert
.sink { ... }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).
@dynamicMemberLookup @preconcurrency @MainActor final class Store<State, Action>A store represents the runtime that powers the application. It is the object that you will pass around to views that need to interact with the application.
@globalActor final actor MainActorA singleton actor whose executor is equivalent to the main dispatch queue.
@dynamicMemberLookup struct StorePublisher<State>A publisher of store state.
@MainActor func ifLet<Wrapped>(then unwrap: @escaping (_ store: Store<Wrapped, Action>) -> Void, else: @escaping () -> Void = {}) -> any Cancellable where State == Wrapped? Calls one of two closures depending on whether a store’s optional state is nil or not, and whenever this condition changes for as long as the cancellable lives.
@MainActor var publisher: StorePublisher<ViewState> { get }A publisher that emits when state changes.
@MainActor convenience init<R>(initialState: @autoclosure () -> R.State, @ReducerBuilder<State, Action> reducer: () -> R, withDependencies prepareDependencies: ((inout DependencyValues) -> Void)? = nil) where State == R.State, Action == R.Action, R : Reducer Initializes a store from an initial state and a reducer.

@discardableResult @MainActor func send(_ action: Action) -> StoreTask Sends an action to the store.
@discardableResult @MainActor func send(_ action: Action, animation: Animation?) -> StoreTask Sends an action to the store with a given animation.

@MainActor func withState<R>(_ body: (_ state: State) -> R) -> R Calls the given closure with a snapshot of the current state of the store.
