With this series of articles I have a lofty goal of shifting your Swift programming mindset. I know, sounds presumptuous, but this is exactly what happened to me a few years back when I was introduced to Type-Driven Design. I assure you, it’s not some new fad or an esoteric methodology. It’s a system of practical, well-researched, and time-tested ideas that form the basis for the powerful approach to writing a high-quality, robust, and correct code.

Principles of Type-Driven Design are widely discussed in various functional programming communities, but are yet to receive a significant attention from the mainstream Swift community. The good news is that many Swift codebases already lean heavily on these principles. And I bet, you are already familiar with many of them. But there’s a tremendous value in structuring fragmented knowledge into a cohesive system, that's when you gain truly deep insights.

So take a cup of coffee, and let’s dive in!
