如何从VStack列表中的项目创建Json？

import SwiftUI

struct ContentView: View {
    struct Item: Codable {
        let name: String
        let description: String
    }
    
    let items: [Item] = [
        Item(name: "Item 1", description: "Description 1"),
        Item(name: "Item 2", description: "Description 2"),
        Item(name: "Item 3", description: "Description 3")
    ]
    
    func createJSON() {
        let encoder = JSONEncoder()
        encoder.outputFormatting = .prettyPrinted
        
        do {
            let jsonData = try encoder.encode(items)
            if let jsonString = String(data: jsonData, encoding: .utf8) {
                print(jsonString)
            }
        } catch {
            print("Error encoding JSON: \(error)")
        }
    }
    
    var body: some View {
        VStack {
            ForEach(items, id: \.name) { item in
                Text(item.name)
                Text(item.description)
            }
        }
        .onAppear {
            createJSON()
        }
    }
}

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