UICollectionViewCompositionalLayout was an important change to how we create collection view layouts. In iOS14 Apple added a new static function to this class which creates a layout object for list views. Meaning, it is very easy to create a list views which look like a table view we are familiar with. The static list() function takes a configuration object UICollectionLayoutListConfiguration which allows further to configure the appearance of the header view. For example, supplementary header views are enabled here. In this blog post, we’ll create a list view with a… Read more Building a list view with collection view in UIKit →
One of the really common layouts I have needed to implement with collection view is a simple flow layout but with fixed spacings. Apple provides us UICollectionViewFlowLayout, but the sad part is that it has dynamic spacing between items. Everything is there but not quite. Before UICollectionViewCompositionalLayout, one needs to create a subclass of the flow layout and then fixing spacings manually, which is pretty cumbersome to do. Therefore, let’s instead see what it takes to implement a simple self-sizing flow layout with fixed spacings when using UICollectionViewCompositionalLayout. The end… Read more Flow layout with self-sizing items and fixed spacing in UIKit →
I have numerous times needed to show some sort of collection view which adjusts its height based on the content. Most of the time it has been a dynamic list within some more complex scrollable UI. Therefore, in this post, we’ll take a look at how to set up a collection view which has its height set to the content height. On the screenshot below, we have a collection view with light grey background and two sections. The approach for making this working is pretty simple, which involves adding a… Read more Height fitting collection view →
