はじめに

おととい、2種類のViewStoreの扱い方を記事にしました。

Reducerはこんな感じ

struct Feature: Reducer {
    struct State: Equatable {
        var text = "Hello, World!"
    }
    
    enum Action: Equatable {
        
    }
    
    func reduce(into state: inout State, action: Action) -> Effect<Action> {
        
    }
}

実装

import SwiftUI
import ComposableArchitecture

struct ContentView: View {
    @ObservedObject private var viewStore: ViewStore<ViewState, Feature.Action>

    let store: StoreOf<Feature>
    
    init(store: StoreOf<Feature>) {
        self.store = store
        self.viewStore = .init(store, observe: ViewState.init(state:))
    }

    struct ViewState: Equatable {
        let text: String
        
        init(state: Feature.State) {
            self.text = state.text
        }
    }

    var body: some View {
        Text(viewStore.text)
    }
}

おわり

いろんな書き方があって難しい
