In SwiftUI, using List
, ForEach
, and lazy containers effectively can boost your app's performance and responsiveness. List
is used to create a scrollable list of views, while ForEach
allows iterating over collections. Lazy containers like LazyVStack
and LazyHStack
help by loading views only when they become visible on the screen, which is efficient for long lists.
struct ContentView: View {
let items = Array(1...1000)
var body: some View {
List {
ForEach(items, id: \.self) { item in
Text("Item \(item)")
}
}
}
}
