Picker in NavigationView: No refresh when custom binding changes - swift

Question

I'm trying to save an enum value to UserDefaults. Therefor I created a custom binding. The UserDefault part works fine but unfortunately the value in the NavigationView does not get refreshed after changing the value with the Picker.
How can I get the chosen weather condition to be displayed?
PS: If not creating additional complexity, I would like to keep the enum Weather of type Int.
import SwiftUI
enum Weather: Int, CaseIterable {
case rain
case sun
case clouds
}
func getWeatherText(weather: Weather) -> String {
switch weather {
case .rain: return "Rain"
case .sun: return "Sun"
case .clouds: return "Clouds"
}
}
struct ContentView: View {
let currentWeather = Binding<Weather>(
get: {
(Weather(rawValue: UserDefaults.standard.integer(forKey: "weather")) ?? .sun)
},
set: {
UserDefaults.standard.set($0.rawValue, forKey: "weather")
}
)
let weathers = Weather.allCases
var body: some View {
NavigationView{
Form{
Picker("Weather", selection: currentWeather) {
ForEach(weathers, id: \.self) { w in
Text(getWeatherText(weather: w)).tag(w)
}
}
}
}
}
}

Thanks to the comment of Asperi, the solution is simple: replacing my custom Binding with #AppStorage. This is the result:
import SwiftUI
enum Weather: Int, CaseIterable {
case rain
case sun
case clouds
}
func getWeatherText(weather: Weather) -> String {
switch weather {
case .rain: return "Rain"
case .sun: return "Sun"
case .clouds: return "Clouds"
}
}
struct ContentView: View {
#AppStorage("weather") var currentWeather: Weather = Weather.clouds
let weathers = Weather.allCases
var body: some View {
NavigationView{
Form{
Picker("Weather", selection: $currentWeather) {
ForEach(weathers, id: \.self) { w in
Text(getWeatherText(weather: w)).tag(w)
}
}
}
}
}
}
