如何将FocusState变量传递给其他视图并允许这些视图更新该变量？[Swift]

import SwiftUI

struct ContentView: View {
    @State private var focusState: FocusState = .notFocused

    var body: some View {
        VStack {
            Text("Focus State: \(focusState.rawValue)")
                .padding()

            Button(action: {
                if focusState == .notFocused {
                    focusState = .focused
                } else {
                    focusState = .notFocused
                }
            }) {
                Text("Toggle Focus")
            }
            .padding()

            AnotherView(focusState: $focusState)
                .padding()
        }
    }
}

struct AnotherView: View {
    @Binding var focusState: FocusState

    var body: some View {
        Text("Another View - Focus State: \(focusState.rawValue)")
            .padding()
            .background(Color.gray.opacity(0.2))
            .cornerRadius(10)
            .onTapGesture {
                if focusState == .notFocused {
                    focusState = .focused
                } else {
                    focusState = .not咛ocused
                }
            }
    }
}

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