  @State private var isLoading = false

  if isLoading {
                                ProgressView()
                            }

                            VStack {

                                ForEach(viewModel2.anuncios.sorted(by: ({ $1.timestampString < $0.timestampString }) ).filter({ "\($0)".contains(searchText) || searchText.isEmpty }) ) { anuncio in
                                    NavigationLink(destination: LazyView(ClassDetailView(anuncio:anuncio))) {
                                        ClassRowView(anuncio:anuncio)
                                    }

                                }

you need to pass into the structure the isLoading value. Where do you start the loading of whatever you are loading?

Hi gfmolon

You need to change the var isLoading to get the data to show have done a small code to show

struct ContentView: View {
    @State private var isLoading = true

    var body: some View {
        Group {
            if isLoading {
                ProgressView()
            } else {
                // code to show data when loaded
                Text("Data loaded")
            }
        }
        .onAppear(perform: loadingCall)
    }

    func loadingCall() {
        // code to load data just using asyncAfter
        DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
            isLoading = false // needed to change to show loaded data
        }
    }
}
