SOLVED: Why does NavigationView render with a different style?

Forums > SwiftUI
@logankriete  

Bit of a SwiftUI neophyte here, purely trying to understand why certain code causes different results! (FWIW, I'm using the new Xcode 12 beta 4.)

I have a (sample) list of dice wrapped in a NavigationView:

struct DieList: View {
    var body: some View {
        NavigationView {
            List {
                Text("Die #1")
                Text("Die #2")
            }
            .navigationBarTitle("Dice")
            //.navigationBarItems(leading: EditButton())
        }
    }
}

And this causes a fairly predictable list with items and a title as expected:

BUT if I uncomment the line of code to create an EditButton in the .navigationBarItems() modifier, suddenly the list looks somewhat different:

Sure, the EditButton shows up, but now there's a grey background, the list items appear with rounded corners, and the lines separating them oddly aren't visible for part of the beginning of each row (look at the whitespace between the dice).

So why does this visual behavior occur?

struct EditButtonView: View {
    @State
    private var collection = [0, 1, 2, 3, 4, 5, 6, 7]
    var body: some View {
        NavigationView {
            List {
                ForEach(collection, id: \.self) {
                    Text("Item #\($0)")
                }
                .onDelete(perform: delete)
            }
            .listStyle(InsetListStyle())
            .navigationBarItems(
                trailing: EditButton())
            .navigationBarTitle("Items")
        }
    }
}

extension EditButtonView {
    private func delete(at offsets: IndexSet) {
        collection.remove(atOffsets: offsets)
    }
}

Thank you, @DimNovo! I was unaware of the .listStyle() modifier. I appreciate the quick response!
