# SwiftUI View for [COMPANY] App

Here's a complete SwiftUI view for displaying [DATA] in a scrollable list with search functionality:

```swift
import SwiftUI
import Combine

struct DataView: View {
    @State private var searchText = ""
    @State private var dataItems: [DataItem] = []
    @State private var isLoading = false
    @State private var errorMessage: String?

    private var filteredItems: [DataItem] {
        if searchText.isEmpty {
            return dataItems
        } else {
            return dataItems.filter { $0.name.localizedCaseInsensitiveContains(searchText) }
        }
    }

    var body: some View {
        NavigationView {
            VStack {
                if isLoading {
                    ProgressView()
                } else if let errorMessage = errorMessage {
                    Text(errorMessage)
                        .foregroundColor(.red)
                } else {
                    List(filteredItems) { item in
                        VStack(alignment: .leading) {
                            Text(item.name)
                                .font(.headline)
                            Text(item.description)
                                .font(.subhead)
                        }
                    }
                }
            }
            .navigationTitle("[DATA] List")
            .searchable(text: $searchText)
            .onAppear {
                loadData()
            }
        }
    }

    private func loadData() {
        isLoading = true
        errorMessage = nil

        // Simulate network request
        DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
            // In a real app, you would make an actual network request here
            // For this example, we'll use mock data
            dataItems = [
                DataItem(name: "Item 1", description: "Description for item 1"),
                DataItem(name: "Item 2", description: "Description for item 2"),
                DataItem(name: "Item 3", description: "Description for item 3"),
                DataItem(name: "Item 4", description: "Description for item 4"),
                DataItem(name: "Item 5", description: "Description for item 5")
            ]
            isLoading = false
        }
    }
}

struct DataItem: Identifiable {
    let id = UUID()
    let name: String
    let description: String
}
```

## Key Components Explained

1. **State Management**: The view uses `@State` properties to manage its internal state, including the search text, data items, loading state, and error messages.
2. **Search Functionality**: The `filteredItems` computed property filters the data items based on the search text.
3. **Error Handling**: The view displays an error message if one occurs during data loading.
4. **Loading State**: A `ProgressView` is shown while data is being loaded.
5. **List Display**: The filtered items are displayed in a scrollable list using the `List` view.
6. **Navigation**: The view is wrapped in a `NavigationView` with a title.
7. **Data Loading**: The `loadData()` function simulates a network request to load data.
