Question

Answer 1

You can do it in two ways.

Firstly, do some modification in layoutAttributesForItem,

get the current attributes's layout via the previous layoutAttributesForItem(at: IndexPath(item: indexPath.item - 1, section: indexPath.section))?.frame.

layoutAttributesForItem(at:): This method provides on demand layout information to the collection view. You need to override it and return the layout attributes for the item at the requested indexPath.

Secondly, new some attributes via UICollectionViewLayoutAttributes(forCellWith: indexPath),layout them wherever you want.

And the math is a little larger, because it performs the heavy lifting of the layout.

layoutAttributesForElements(in:): In this method you need to return the layout attributes for all the items inside the given rectangle. You return the attributes to the collection view as an array of UICollectionViewLayoutAttributes.
