— My talk @ FrenchKit 2016. Video available here: https://youtu.be/BSn4jlunn4I
Embark in a journey with some Sci-Fi characters to discover how the Mixins & Traits pattern can help you better design your classes, avoid multiple-inheritance problems, and propose a protocol-oriented, Crusty-approved™ alternative to composition!
In this talk you'll discover what Mixins & Traits are, and how they can help avoid the problems otherwise brought by inheritance and be an interesting alternative to composition, by leveraging the Protocol-Oriented features of Swift.
We'll start by demonstrating the limitations of inheritance (and even composition) in some concrete examples, then present the concept of Mixins & Traits.
With the help of some fun examples and a bunch of Sci-Fi characters, we'll then see how this Mixins & Traits pattern can solve those problems, make your architecture more flexible, protocol-oriented… and allowing to factorize your code in a new way.
We'll finish the talk with a very concrete use case of Mixins that will allow you to get rid of String-based APIs like UITableViewCells,, UICollectionViews and UIStoryboard APIs, and make your code type-safe thanks to this Swift magic! ✨🎩
