하위 View에 프로퍼티 전달하기 (바인딩)

struct ContentView: View {
    
    @State private var wifiEnabled = true
    @State private var userName = ""
    
    var body: some View {
        VStack {
            
            Text(userName)
            
            Toggle(isOn : $wifiEnabled){
                Text("enalble wi-fi")
            }
            TextField("Enter user name", text: $userName)
            WifiImageView(wifi: $wifiEnabled)
        }
    }
}
struct WifiImageView: View {
    @Binding var wifi: Bool
    var body: some View {
        Image(systemName: wifi ? "wifi" : "wifi.slash")
    }
}
