To reimplement swipe actions for a LazyVStack
in SwiftUI, you can follow the principles discussed in the SwiftUI essentials session. Here are the steps you can take:
- Create a
LazyVStack
: This will be the container for your list of items. - Use
ForEach
to generate rows: Each row can represent an item in your list. - Add swipe actions to each row: You can use the
swipeActions
modifier to add actions to each row.
Here is a basic example:
import SwiftUI
struct ContentView: View {
@State private var items = ["Item 1", "Item 2", "Item 3"]
var body: some View {
LazyVStack {
ForEach(items, id: \.self) { item in
Text(item)
.swipeActions {
Button("Delete") {
if let index = items.firstIndex(of: item) {
items.remove(at: index)
}
}
.tint(.red)
}
}
}
}
}
Explanation:
- LazyVStack: This is used to create a vertically scrolling stack of views.
- ForEach: This iterates over the items in your list and creates a view for each item.
- swipeActions: This modifier is used to add swipe actions to each row. In this example, a "Delete" button is added, which removes the item from the list when tapped.
For more detailed information on how to use swipeActions
and other SwiftUI capabilities, you can refer to the SwiftUI essentials session.
