SwiftUI选取器不与ObservedObject绑定

import SwiftUI
import Combine

class DataStore: ObservableObject {
    @Published var selectedOption: String = ""
    
    // 此处省略了数据源的初始化和更新的逻辑
}

struct ContentView: View {
    @ObservedObject var dataStore = DataStore()
    @State private var selectedOption: String = ""
    
    var body: some View {
        VStack {
            Picker(selection: $selectedOption, label: Text("Options")) {
                Text("Option 1").tag("Option 1")
                Text("Option 2").tag("Option 2")
                Text("Option 3").tag("Option 3")
            }
            .onReceive(dataStore.$selectedOption) { newSelectedOption in
                self.selectedOption = newSelectedOption
            }
            
            Text("Selected Option: \(selectedOption)")
        }
    }
}

// 示例中的DataStore类作为数据源对象，提供选取器所需的属性和方法。ContentView视图中使用了@ObservedObject包装器将DataStore对象与视图进行绑定，并通过onReceive修饰符监听其变化，并更新@State属性，以便选取器可以响应数据源的变化。
