How do I implement search and filtering in Combine with Swift?

Implementing search and filtering using Combine in Swift is a powerful way to handle dynamic data queries. Below is an example of how you can achieve this functionality.


    import SwiftUI
    import Combine

    struct Item: Identifiable {
        let id: UUID
        let name: String
    }

    class ViewModel: ObservableObject {
        @Published var items: [Item] = [
            Item(id: UUID(), name: "Apple"),
            Item(id: UUID(), name: "Banana"),
            Item(id: UUID(), name: "Cherry")
        ]
        @Published var searchText: String = ""

        var cancellables = Set()

        init() {
            $searchText
                .combineLatest($items)
                .map { searchText, items in
                    return items.filter { item in
                        searchText.isEmpty || item.name.lowercased().contains(searchText.lowercased())
                    }
                }
                .assign(to: &$filteredItems)
        }

        @Published var filteredItems: [Item] = []
    }

    struct ContentView: View {
        @ObservedObject var viewModel = ViewModel()

        var body: some View {
            VStack {
                TextField("Search items...", text: $viewModel.searchText)
                    .padding()
                    .textFieldStyle(RoundedBorderTextFieldStyle())

                List(viewModel.filteredItems) { item in
                    Text(item.name)
                }
            }
        }
    }
