How is the section height determined?

Changing the group height to fractional height (.fractionalHeight(0.6)) or any other value such as 0.5, 0.4, 0.3 has an expected behavior.

Steps to reproduce:
Change background of cell to Purple (Or Any) Color

For the line :slight_smile:

let groupSize = NSCollectionLayoutSize(widthDimension: .fractionalWidth(1.0), heightDimension: .fractionalHeight(0.6)

change the value of height dimension to different value, such as 0.5.

You can see that after some cells, there is a very thin white spacing. Not sure where is that coming from?

Will try and replicate this to see what I can find
