Output Format

swift

// iOS SwiftUI Example
import SwiftUI
import Combine

struct ContentView: View {
    @StateObject private var viewModel = ViewModel()
    
    var body: some View {
        NavigationView {
            List(viewModel.items) { item in
                ItemRow(item: item)
            }
            .navigationTitle("App Title")
            .task {
                await viewModel.loadData()
            }
        }
    }
}

@MainActor
class ViewModel: ObservableObject {
    @Published var items: [Item] = []
    
    func loadData() async {
        // Async data loading
    }
}

kotlin

// Android Compose Example
@Composable
fun MainScreen(
    viewModel: MainViewModel = hiltViewModel()
) {
    val uiState by viewModel.uiState.collectAsState()
    
    LazyColumn(
        modifier = Modifier.fillMaxSize(),
        contentPadding = PaddingValues(16.dp)
    ) {
        items(uiState.items) { item ->
            ItemCard(item = item)
        }
    }
}

@HiltViewModel
class MainViewModel @Inject constructor(
    private val repository: Repository
) : ViewModel() {
    val uiState = repository.getData()
        .stateIn(viewModelScope, SharingStarted.Lazily, UiState())
}
