Studing SwiftUI in Apple's HandlingUserInput, I'm blocked in this error:No ObservableObject of type UserData found. A View.environmentObject(_:) for UserData may be missing as an ancestor of this view.The code is:final class UserData: ObservableObject { @Published var showFavoritesOnly = false @Published var landmarks = landmarkData }struct LandmarkList: View { @EnvironmentObject var userData: UserData var body: some View { NavigationView { List(landmarkData) { landmark in if !self.userData.showFavoritesOnly || landmark.isFavorite { NavigationLink(destination: LandmarkDetail(landmark: landmark)) { LandmarkRow(landmark: landmark) } } } .navigationBarTitle(Text("Landmarks")) } } } struct LandmarkList_Previews: PreviewProvider { static var previews: some View { LandmarkList() .environmentObject(UserData()) } }".environmentObject(UserData())" is present in the preview."@EnvironmentObject var userData: UserData" in the View.But the use of userData (if !self.userData.showFavoritesOnly) cause the fatal error.Can someone help me in undertanding how to proceed?

On App Store there is the new request to declared if I am a trader operator or not under the new EU law. As many I'm a single developer so the declaration can be reduced to "any natural person [...] who is acting [...] for purposes relating to his or her trade, business, craft or profession.", to learn more Apple links to EU commission. I'm not 100% sure if, a single developer whit very small business and which use only Apple Store to distribute its apps, can declared "This is the account of a supplier who is not a trader". Is someone more legal expert than me able to replay?
