ios – Tips on how to Move @State and @Binding into SwiftUI Essential App Struct

I am fairly new to SwiftUI, apologies prematurely if this a poor query, I’ve researched and I can not appear to seek out the reply. In my ContentView I’ve a few stateful variables that retailer values for my slider in a sub view (CustomTextFieldAndSlider) beneath that.

How will we retailer these stateful variables with out having to move them into the @fundamental
app struct myAppApp.swift? Once I do move them into the @fundamental App struct I’ve to hardcode them as .fixed / textual content parameters which does not permit the stateful performance desired.

@fundamental MyAppApp.swift

import SwiftUI

@fundamental
struct Foo: App {
    
    var physique: some Scene {
        WindowGroup {
            ContentView(homePriceText: "")
        }
    }
}

ContentView

struct ContentView: View {

    @State var homePriceText: String
    @State var homePrice: Double = 0
    
    var physique: some View {
        ZStack{
            Coloration.grey.opacity(0.1)
            VStack(alignment: .main) {
                CustomTextFieldAndSlider(labelText: "foo", placeholder: "foo", showLeadingIcon: true, leadingIcon: "dollarsign.circle", textBinding: $homePriceText, sliderBinding: $homePrice)
            }
            .padding()
        }
        .ignoresSafeArea()
        
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView(homePriceText: "0", homePrice: 200000)
    }
}
