Thanks for spotting that @sorin36

Because it is creating a custom layout section, the demo needed to add headers/footers to the NSCollectionLayoutSection...

let supplementarySize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1.0), heightDimension: .estimated(50))
let headerSupplementary = NSCollectionLayoutBoundarySupplementaryItem(
	layoutSize: supplementarySize,
	elementKind: UICollectionView.elementKindSectionHeader,
	alignment: .top)
let footerSupplementary = NSCollectionLayoutBoundarySupplementaryItem(
	layoutSize: supplementarySize,
	elementKind: UICollectionView.elementKindSectionFooter,
	alignment: .bottom)
section.boundarySupplementaryItems = [headerSupplementary, footerSupplementary]
