Hi, I have this simple view in SwiftUI, where it's possible to move a single row and select one or more rows.
When I select 2 or more rows and try to move them I got this error log:
Did I do something wrong or it's bug in SwiftUI? Is it possible to move more than 1 row at once?
Thanks a lot!
Code Block swift struct ContentView: View { @State var selectedItems = Set<Int>() @State var items = Array(1...10).map({ S(id: $0) }) var body: some View { List(selection: $selectedItems) { ForEach(items) { (item) in Text(String(item.id)) .padding() } .onMove(perform: { indices, newOffset in withAnimation { self.items.move(fromOffsets: indices, toOffset: newOffset) } }) } } }
When I select 2 or more rows and try to move them I got this error log:
