Adjust insets of a specific section in UICollectionView

Adjust insets of a specific section in UICollectionView
insetForSectionAtIndex (on DelegateFlowLayout) enables one to set insets for all cells within a section
sectionInset (on FlowLayout) enables one to set insets that applies to all sections.
However, I am looking for a way of applying insets to only one specific section - is this possible?

You must have to implement UICollectionViewDelegateFlowLayout to your class with this method:
UICollectionViewDelegateFlowLayout
For Swift 4
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets
var edgeInsets = UIEdgeInsets()
if section == THE_SECTION_YOU_WANT
// edgeInsets configuration stuff
return edgeInsets;
For Swift 3
func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets
var edgeInsets = UIEdgeInsets()
if section == THE_SECTION_YOU_WANT
// edgeInsets configuration stuff
return edgeInsets;
@GauravSharma This method apply the inset to the entire section, that's the reason it gives it an section

Int
just tried again - same result - it applies the insets to each cell in the section, rather than the section.

@GauravSharma and what is the difference? Do you want to apply the inset to the header section and footer section?

Nope, I want to inset the entire section (not each item in the section).

I tried this earlier, and it seems to apply the inset to all elements in the section. Is there a way I can apply it to the entire section, not each element?
