In this course, you’ve been working with sections of views. But you haven’t used SwiftUI’s Section View. In this episode, that will change! Sections are used for adding headers and footers to views, and there are a couple of associated options available to you. Let’s check ’em out.

LazyVStack(pinnedViews: [.sectionHeaders, .sectionFooters]) {

LazyHStack(pinnedViews: [.sectionHeaders, .sectionFooters]) {

        pinnedViews: [.sectionHeaders, .sectionFooters]
      ) {

rows: .init(repeating: .init(), count: 6),

ForEach(genre.subgenres) {
