ios – onChange for picker not working after closing app and opening once more

I am constructing a app and I’ve a Picker wheel and I discovered you should utilize .onChange to detect a change within the picker.

So I ended up with this code:

struct ContentView: View {
    let languages = ["English", "Chineese", "French", "Spanish"]
    @State personal var language = "English"
    var physique: some View {
        Picker("Language", choice: $language) {
            ForEach(languages, id: .self) {
                Textual content($0)
            }
        }
        .pickerStyle(.wheel)
        .onChange(of: language) { newValue in
            print("Labored!")
        }
    }
}

It really works as anticipated the when first constructing and launching the app and prints out “Labored!” correctly. However closing the app and reopening it, I can nonetheless use the picker, however once I transfer the picker it doesn’t print “Labored!”. I could not discover out why or discover something on-line about it, so I am actually confused.

Here is a GIF exhibiting what’s taking place:
