How to create grouped and inset grouped lists

SwiftUI’s List views have a listStyle() modifier to control how the list looks, and there are two options you’re likely to want: GroupedListStyle() to get the old-style grouping of items, and InsetGroupedListStyle() to get the newer iOS 13-style grouping of items.

For example, this defines an example row and places it inside a grouped list:

struct ExampleRow: View {
    var body: some View {
        Text("Example Row")
    }
}

struct ContentView: View {
    var body: some View {
        List {
            Section(header: Text("Examples")) {
                ExampleRow()
                ExampleRow()
                ExampleRow()
            }
        }
        .listStyle(GroupedListStyle())
    }
}

Alternatively, this will create a list of 100 rows with the new inset style of grouping:

List(0..<100) { i in
    Text("Row \(i)")
}
.listStyle(InsetGroupedListStyle())
