How do I display paginated lists in Combine with Swift?

Displaying paginated lists in Combine with Swift can enhance the user experience by efficiently loading data. This approach allows you to manage large datasets by breaking them into smaller, manageable chunks, loading more data as the user scrolls or requests it.

Example Code:

// Import Combine and SwiftUI import SwiftUI import Combine struct ContentView: View { @StateObject private var viewModel = PaginatedViewModel() var body: some View { List { ForEach(viewModel.items, id: \.id) { item in Text(item.name) } if viewModel.isLoading { ProgressView() } } .onAppear { viewModel.loadMoreItems() } .onInfiniteScroll { viewModel.loadMoreItems() } } } class PaginatedViewModel: ObservableObject { @Published var items: [Item] = [] @Published var isLoading = false private var currentPage = 1 func loadMoreItems() { guard !isLoading else { return } isLoading = true // Replace with your own data fetching logic let newItems = fetchData(page: currentPage) items.append(contentsOf: newItems) currentPage += 1 isLoading = false } // Dummy data fetching method private func fetchData(page: Int) -> [Item] { // Fetch and return array of items return (1...10).map { Item(id: $0 + (page - 1) * 10, name: "Item \($0 + (page - 1) * 10)") } } } struct Item: Identifiable { let id: Int let name: String }
