SwiftUI从一个列表拖动到另一个列表

struct ContentView: View {
    @State private var sourceItems = ["Item 1", "Item 2", "Item 3"]
    @State private var targetItems = [String]()

    var body: some View {
        HStack {
            List(sourceItems, id: \.self) { item in
                Text(item)
                    .onDrag {
                        NSItemProvider(object: item as NSString)
                    }
            }
            .frame(maxWidth: .infinity)

            List(targetItems, id: \.self) { item in
                Text(item)
            }
            .frame(maxWidth: .infinity)
            .onDrop(of: [UTType.text], isTargeted: nil) { providers, location in
                for provider in providers {
                    provider.loadObject(ofClass: NSString.self) { item, error in
                        if let item = item as? String {
                            DispatchQueue.main.async {
                                targetItems.insert(item, at: location)
                            }
                        }
                    }
                }
                return true
            }
        }
    }
}
