Implementing pull-to-refresh in a SwiftUI application using Combine can enhance the user experience by allowing users to refresh content easily. Below is a simple implementation example.
import SwiftUI
import Combine
struct ContentView: View {
@State private var items: [String] = []
@State private var isRefreshing: Bool = false
private var cancellable: AnyCancellable?
var body: some View {
List(items, id: \.self) { item in
Text(item)
}
.refreshable {
await loadData()
}
.onAppear {
loadData()
}
.overlay {
if isRefreshing {
ProgressView()
}
}
}
private func loadData() async {
isRefreshing = true
// Simulate network delay
try? await Task.sleep(nanoseconds: 2_000_000_000)
items = ["Item 1", "Item 2", "Item 3", "Item 4"]
isRefreshing = false
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
