当SwiftUI选择器选择更改EnvironmentObject时，有没有办法调用函数？

import SwiftUI

class UserData: ObservableObject {
    @Published var selectedOption: String = ""
}

struct ContentView: View {
    @EnvironmentObject var userData: UserData
    
    var body: some View {
        VStack {
            Picker("Options", selection: $userData.selectedOption) {
                Text("Option 1").tag("option1")
                Text("Option 2").tag("option2")
                Text("Option 3").tag("option3")
            }
            .pickerStyle(SegmentedPickerStyle())
            .onReceive(userData.$selectedOption) { selectedOption in
                // 在选择器选择更改EnvironmentObject时调用函数
                self.handleSelectionChange(selectedOption)
            }
        }
    }
    
    func handleSelectionChange(_ selectedOption: String) {
        // 执行相应的操作
        print("Selected option: \(selectedOption)")
    }
}

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