在不使用导航链接的情况下获取SwiftUI列表中的选定项目

import SwiftUI

struct ContentView: View {
    struct Item: Identifiable {
        let id: UUID
        let name: String
    }
    
    @State private var selectedItemId: UUID?
    
    let items = [
        Item(id: UUID(), name: "Item 1"),
        Item(id: UUID(), name: "Item 2"),
        Item(id: UUID(), name: "Item 3")
    ]
    
    var body: some View {
        VStack {
            List {
                ForEach(items) { item in
                    Text(item.name)
                        .onTapGesture {
                            selectedItemId = item.id
                        }
                }
            }
            
            if let selectedItem = items.first(where: { $0.id == selectedItemId }) {
                Text("Selected Item: \(selectedItem.name)")
            } else {
                Text("No item selected")
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
