Not able to achieve dark mode using SwiftUI [duplicate]

Question

struct ContentView_Previews : PreviewProvider {
    static var previews: some View {
        ContentView().environment(\.colorScheme, .dark)
    }
}

I am using the above code to achieve dark mode on my demo project but its not working.
Any help or insight would be really appreciated.

This seems to be a bug in Xcode 11.0 beta. A temporary workaround is to wrap your content inside a NavigationView.

For example, the following code will not take effect in dark mode preview:

var body: some View {
  Text("Hello World")
}

But after wrapping the content in a NavigationView, dark mode preview works as expected:

var body: some View {
  NavigationView {
    Text("Hello World")
  }
}

Result:
