            .padding()
            .navigationTitle("Text to Speech")
        }
    }
}


#Preview {
    HomeView()
        .environmentObject(Data())
}
class Data: ObservableObject {
    @Published var changevoice = true
}

import SwiftUI
struct SettingsView: View {
    @EnvironmentObject var data: Data
    var body: some View {
        NavigationView {
            List {
                Toggle(isOn: $data.changevoice) {
                    Text("Disable Voice Changing")
                }.tint(.blue)
            }.navigationTitle("Settings")
        }
    }
}

#Preview {
    SettingsView()
        .environmentObject(Data())
}

Text to speech app having having a change voice button to switch between male and female voice, want to disable that button through another view WHAT I AM DOING WRONG?(Beginner) there are two views homeview and settings view, the toggle is on settings view and the button in on homeview, it is only taking the value which i am passing in class
