How can I get IndexPath from minimumLineSpacingForSectionAt to set different spacing between items in a collectionview?

Question

Normally I just use this function:

optional func collectionView(_ collectionView: UICollectionView, 
                      layout collectionViewLayout: UICollectionViewLayout, 
minimumLineSpacingForSectionAt section: Int) -> CGFloat

to set some spacing between the items in a collectionView, but the spacing is the same for all items. I would like to set the spacing to be different between some items, depending on some logic that I need to check, the logic will depend on which cell is before and after, so I would need something like IndexPath to check that.

When we want to set size of a cell, we conveniently get IndexPath from the function below, but not from the function above.

optional func collectionView(_ collectionView: UICollectionView, 
                      layout collectionViewLayout: UICollectionViewLayout, 
               sizeForItemAt indexPath: IndexPath) -> CGSize

What can I do to achieve this?

There's no good way to do it without creating your own layout. There's too much to it to go into it here, but there's tons of good tutorials on the matter. Here's a good place to start.
