I'm trying to create a sticky supplementary header, which stays on top all the time and won't response to scrolling events. The solutions I found so far still react on bounch scrolling and are fixed using a custom flowLayout, which will probably be the fix for mine issue as well.

The reason I want it this way is that the header is used on other places and should be reusable. I'm hoping this could be solved this way and I don't have to create a separated view.

As I'm doing this in Swift, it would be great to have an example in Swift.

Simplest solution for iOS 9 + as it doesn't need of writing subclass of UICollectionViewFlowLayout.

In viewDidLoad of viewController with collectionView use following code:

let layout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout // casting is required because UICollectionViewLayout doesn't offer header pin. Its feature of UICollectionViewFlowLayout
layout?.sectionHeadersPinToVisibleBounds = true

It is hinted by @Antoine also.
