This week I gave a talk at intive about implementing custom UICollectionView layouts. The talk was regarding internal project, so I am not able to share code etc., but I thought I’d share the presentation - link.

I’d like to share my approach to flexible UI components styling in Swift. Some of the advantages are that it can be used for white-label product development and allows for clear styling definition in one place.

It may happen that two objects reference each other, so one of them needs to weakly reference the order in order to avoid memory leaks. I would like to show you my approach to defining such requirements at the protocol level.

In this article I’d like to show some implementation details about Error type in Swift and how one can leverage localizedDescription property (and how to actually make it work). On top of that I’d like to show you a little tip on how you could implement extendable error messaging in your framework.
