SOLVED: Day 42: Dark background not applying for custom ListLayout

Forums > 100 Days of SwiftUI


I'm on Day 42 of the course and I am not able to apply the custom .darkBackground modifier to my custom ListLayout. It just shows the default dark mode background.

Here is my ContentView:

struct ContentView: View {
    let astronauts: [String: Astronaut] = Bundle.main.decode("astronauts.json")
    let missions: [Mission] = Bundle.main.decode("missions.json")

    @State private var showingGrid = true

    var body: some View {
        NavigationStack {
            Group {
                if showingGrid {
                    GridLayout(astronauts: astronauts, missions: missions)
                } else {
                    ListLayout(astronauts: astronauts, missions: missions)
            .toolbar {
                Button("Switch Layout") {

Here is my ListLayout:

struct ListLayout: View {
    let astronauts: [String: Astronaut]
    let missions: [Mission]

    var body: some View {
        List {
            ForEach(missions) { mission in
                NavigationLink {
                    MissionView(mission: mission, astronauts: astronauts)
                } label: {
                    HStack {
                        VStack(alignment: .leading) {



                            .frame(width: 50, height: 50)


Normally, you can’t see backgrounds on lists because it is covered up by the system background. In order you can see your applied background you will need to apply following modifier to your List view.


or another way it to use the below modifier for the entire List and remove .background() modifier



What some people may get confused about is that you have to apply the .listRowBackground(_ View:) to the ForEach. Hope that helps! Some example code:

List {
  ForEach(0..<5) {
     Text("Dynamic Row \($0)")
