List, ForEach & Identifiable

Render dynamic collections efficiently with stable identity, swipe actions and sections.

List builds a scrolling, cell-reusing list. ForEach generates views for each element and needs stable identity — conform your model to Identifiable.

Add swipe actions, onDelete and sections to get native iOS behavior for free.

1struct Todo: Identifiable {

11            Section("Today") {
12                ForEach(todos) { todo in
13                    Text(todo.title)
14                        .swipeActions {
15                            Button("Delete", role: .destructive) {
16                                todos.removeAll { $0.id == todo.id }
17                            }
18                        }
19                }
20            }
21        }

Common pitfalls

Avoid id: \.self for values that can repeat — duplicate IDs cause glitches and crashes.
