如何使用picker的核心数据值？#SwiftUI #CoreData

import SwiftUI

struct ContentView: View {
    @State private var selectedOption: String = ""
    let options = ["Option 1", "Option 2", "Option 3"]

    var body: some View {
        VStack {
            Picker("Select an option", selection: $selectedOption) {
                ForEach(options, id: \.self) { option in
                    Text(option)
                }
            }
            .pickerStyle(DefaultPickerStyle()) // 设置Picker的样式

            Text("Selected option: \(selectedOption)")
        }
    }
}

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