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

Here is my alternative which seems to work better on iOS12 when subclassing UICollectionReusableView.

final class BasicCollectionSectionHeader: UICollectionReusableView {
    override var layer: CALayer {
        let layer = super.layer
        layer.zPosition = 0 // make the header appear below the collection view scroll bar
        return layer
    }
}
