UICollectionViewFlowLayoutDelegate insetForSectionAt never called

swift3

I need to use some optional methods of UICollectionViewDelegateFlowLayout, however method below is never called.

insetForSectionAt

optional public func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets

Since UICollectionViewDelegateFlowLayout inherited from UICollectionViewDelegate - all I need to do is to assign collection'sView delegate:

self.collectionView.delegate = self.delegate

Note that everything else works fine and methods like sizeForItem or cellForItem gets called.

Please make sure if you have implemented UICollectionViewDelegateFlowLayout in your class like this:

class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout {

//...your code here

}
