Both networking and protocols are topics that I could write dozens of posts on, and I would still have more ideas and examples left in my head. In today’s article, I would like to combine the topics of networking and protocols and explain how you can design a robust networking layer for your app, that’s […]

Whenever we write code, we want our code to be well-designed. We want it to be flexible, elegant and safe. We want to make sure that Swift’s type system and the compiler catch as many of our mistakes as possible. It’s especially interesting how Swift’s type system can help us avoid obvious errors. For example, […]
