问题 I'm am trying to achieve dark mode within my iOS application using SwiftUI: simple test would be to change the background colour. I have set up my colour set as seen below: ContentView.swift: import SwiftUI struct ContentView : View { @EnvironmentObject var session: SessionStore func getUser () { session.listen() } var body: some View { Group { if (session.session != nil) { VStack { WelcomeView() .background(Color("bg")) .edgesIgnoringSafeArea(.all) } } else { VStack { SigninView().transition

问题 I am trying to drag and drop between to Lists. What I have tried: I have found a solution doing it in UIKIt and the using UIViewControllerRepresentable. But that is not what i want.
