Scrollbar incorrectly appears underneath UICollectionView section header

Question

For some reason my scrollbar always appears underneath the collection view section header. Any help is greatly appreciated!

Answer 1

With a long-scrolling, async-loading collection, this alternative may offer slightly better performance.

class MyHeaderView: UICollectionReusableView {
    override func apply(_ layoutAttributes: UICollectionViewLayoutAttributes) {
        layer.zPosition = 0
    }
}
