I am using a UICollectionView in my project, where there are multiple cells of differing widths on a line. According to: https://developer.apple.com/library/content/documentation/WindowsViews/Conceptual/CollectionViewPGforIOS/UsingtheFlowLayout/UsingtheFlowLayout.html
it spreads the cells out across the line with equal padding. This happens as expected, except I want to left justify them, and hard code a padding width.
I figure I need to subclass UICollectionViewFlowLayout, however after reading some of the tutorials etc online I just don't seem to get how this works.
