SwiftUI List Showing as Blank for non-empty List

Question

I am trying to create a simple list view in SwiftUI however, it shows up as blank (pictured below) no matter how many objects are in the array. If I get rid of the list, it will show the elements of the array. I know for a fact that the array is not empty. Any recommendations on how to fix it.

This is my code"

var body: some View {
        NavigationView {
            ScrollView {
                if(leaderboard.isEmpty) {
                    
                    VStack {
                        Text("No Entries Yet :(")
                            .foregroundColor(.gray)
                            .font(.largeTitle)
                    }
                } else {
                    ScrollView {
                        List {
                            ForEach(leaderboard.asArray(), id: \.self) { score in
                                Text("\(score)")
                            }
                        }
                    }
                }
            }
            .navigationBarTitle("Leaderboard")
        }
    }

Here is what the view currently shows:

Also, bonus points if you can help me make it so the Text("No Entries Yet :( ") is centered vertically within the view.

Yeah and IIRC the ScrollView becomes extremely tiny in height to the point where you can't see it. Remove both ScrollViews. — aheze

You don't need either of those ScrollViews - If the list is empty you only have the text view. If the list isn't empty, List provides the necessary scroll view.

To vertically centre the text when the list is empty, simply add Spacer views above and below:

struct ContentView: View {
    var body: some View {
        
        let leaderboard:[Int] = [10,20,30,40,100,1999,1393,444]
        NavigationView {
            if(leaderboard.isEmpty) {
                VStack {
                    Spacer()
                    Text("No Entries Yet :(")
                        .foregroundColor(.gray)
                        .font(.largeTitle)
                    Spacer()
                }
            } else {
                List {
                    ForEach(leaderboard, id: \.self) { score in
                        Text("\(score)")
                    }
                }
            }
        }
        .navigationBarTitle("Leaderboard")
    }
}

If your list is empty, just add another row without background. Stylish it as you want.

if rows.isEmpty {
    Text("No records")
        .listRowBackground(EmptyView())
}
