How do I implement Redux-style architecture in SwiftUI?

Implementing Redux-style architecture in SwiftUI allows for predictable state management, making it easier to manage the app's state, debug issues, and enhance code readability. This architecture revolves around a unidirectional data flow, where actions are dispatched to modify the state, leading to view updates.

    // Example of implementing Redux-like architecture in SwiftUI

    import SwiftUI
    import Combine

    // Define the AppState
    struct AppState {
        var count: Int = 0
    }

    // Define Actions
    enum Action {
        case increment
        case decrement
    }

    // Define a reducer function
    func reducer(state: inout AppState, action: Action) {
        switch action {
        case .increment:
            state.count += 1
        case .decrement:
            state.count -= 1
        }
    }

    // Create a Store
    class Store: ObservableObject {
        @Published var state = AppState()

        func dispatch(_ action: Action) {
            reducer(state: &state, action: action)
        }
    }

    // Create a SwiftUI View
    struct ContentView: View {
        @ObservedObject var store = Store()

        var body: some View {
            VStack {
                Text("Count: \(store.state.count)")
                HStack {
                    Button(action: {
                        store.dispatch(.increment)
                    }) {
                        Text("Increment")
                    }
                    Button(action: {
                        store.dispatch(.decrement)
                    }) {
                        Text("Decrement")
                    }
                }
            }
        }
    }

    // Main application structure
    @main
    struct MyApp: App {
        var body: some Scene {
            WindowGroup {
                ContentView()
            }
        }
    }
