Redux-like state container in SwiftUI. Usage.

We can finish our repos search app that calls Github API asynchronously and fetches repositories matching a query.

typealias AppStore = Store<AppState, AppAction, AppEnvironment>

struct SearchContainerView: View {
    @EnvironmentObject var store: AppStore
    @State private var query: String = "Swift"

    var body: some View {
        SearchView(
            query: $query,
            repos: store.state.searchResult,
            onCommit: fetch
        ).onAppear(perform: fetch)
    }

    private func fetch() {
        store.send(.search(query: query))
    }
}

struct SearchView : View {
    @Binding var query: String
    let repos: [Repo]
    let onCommit: () -> Void

    var body: some View {
        NavigationView {
            List {
                TextField("Type something", text: $query, onCommit: onCommit)

                if repos.isEmpty {
                    Text("Loading...")
                } else {
                    ForEach(repos) { repo in
                        RepoRow(repo: repo)
                    }
                }
            }.navigationBarTitle(Text("Search"))
        }
    }
}
Enter fullscreen mode Exit fullscreen mode

We divide our screen into two views: Container View and Rendering View. Container View handles the actions and retrieves the needed piece of state from the global state. Rendering View accepts the data and renders it.

I have a clear focus on time-to-market and don't prioritize technical debt. And I took part in the Pre-Sale/RFX activity as a System Architect, assessment efforts for Mobile (iOS-Swift, Android-Kotlin), Frontend (React-TypeScript) and Backend (NodeJS-.NET-PHP-Kafka-SQL-NoSQL). And I also formed the work of Pre-Sale as a CTO from Opportunity to Proposal via knowledge transfer to Successful Delivery.
