Protocols

A protocol to help guide structuring a SwiftUI view to use RedUx.

The use of this protocol isn’t required in order to use RedUx. It can be used as a guide on how to setup RedUx.

An example of this may look like:

import RedUx
import SwiftUI


struct RootScreen: View, RedUxable {
    typealias LocalState = AppState
    typealias LocalEvent = AppEvent
    typealias LocalEnvironment = AppEnvironment

    let store: LocalStore
    @StateObject var viewModel: LocalViewModel

    // MARK: Initialization

    init(store: LocalStore, viewModel: LocalViewModel) {
        self.store = store
        self._viewModel = .init(wrappedValue: viewModel)
    }

    // MARK: Body

    var body: some View {
        VStack(alignment: .center) {
            Text(verbatim: .init(self.viewModel.count))
                .font(.largeTitle)

            HStack {
                Button("Decrement") {
                    self.viewModel.send(.decrement)
                }
                .buttonStyle(.bordered)

                Button("Increment") {
                    self.viewModel.send(.increment)
                }
                .buttonStyle(.bordered)

                Button("Delayed increment") {
                    self.viewModel.send(.incrementWithDelay)
                }
                .buttonStyle(.bordered)
            }
        }
    }
}



// MARK: Preview

struct RootScreen_Previews: PreviewProvider {
    static var previews: some View {
        RootScreen.mock(
            state: .init(
                count: 0
            ),
            environment: .mock
        )
    }
}
