One of the topics that I could write dozens of posts on is networking. Making calls to a remote API to retrieve or persist data is something that is a key feature in many apps that are currently in the App Store. Some apps make extensive use of the network Read more…
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 Read more…

As apps grow larger and larger, their complexity tends to increase too. And quite often, the problems you’re solving become more specific and niche over time as well. If you’re working on an app like this, it’s likely that at some point, you will notice that there are parts of Read more…
As developers, we are often told that we should avoid crashing our apps at all costs. It’s why we are told that we shouldn’t force unwrap our optionals, that we should avoid unowned references and that we should never use try! in production code. In today’s article, I would like Read more…
