We have all used collection views to display our data in a horizontal or vertical grid thanks to the flow layout provided to us by Apple. What if you need to lay your data out in a manner that isn’t a grid? What if you really need a graph? In this session we will explore the not-so-hidden gems inside of UICollectionViewLayout. Armed with this knowledge we will create a circular graph layout, delegate protocol, and wire everything up to a plain-jane UICollectionView.
