Swift has many features that allow us as the users of the language to customize how we write code, while still giving us all the protections of a statically typed language. Today we’re going to talk about one of those features which seems small, but it packs a lot of punch. The typealias keyword lets you define a “type alias”, a custom name for a class, struct or any other existing type in Swift....
I don’t know about you, but I have spent a lot of time trying to write code in the shortest, most elegant way possible. I have put a lot of thought and time and effort into it over the years. And I see it a lot in other people’s code as well. I have seen it from both junior and senior developers. I have seen it in new code bases and mature code bases, both large and small....
I am looking for an excuse to learn more about algorithms, so I am going to write a series of posts that cover some of the most common ones and examine at what they might look like in Swift. I know algorithms often feel like an academic topic – something for nerds in computer science classes. They can be intimidating because their explanations and examples tend to be math-heavy and there is a lot of hard-to-decipher jargon out there about them....
