拾取器不从CoreData (SwiftUI)中选择值

struct PickerData: Identifiable {
    let id = UUID()
    let value: String
}

@State private var pickerData: [PickerData] = [
    PickerData(value: "Option 1"),
    PickerData(value: "Option 2"),
    PickerData(value: "Option 3")
]

@State private var selectedOption: PickerData?

Picker(selection: $selectedOption, label: Text("Select Option")) {
    ForEach(pickerData) { data in
        Text(data.value).tag(data)
    }
}

.onReceive(Just(selectedOption)) { option in
    if let selectedOption = option {
        // 处理选择的选项值
        print("Selected option: \(selectedOption.value)")
    }
}
