Point-Free - A video series exploring functional programming and Swift (Updated 03.2025)

Unfortunately, functional programming is sometimes seen as overly academic or unapproachable. That's a shame because it's a really beautiful way of doing programming, just a little different from what we are used to. It emphasizes immutable values, which means you are not allowed to mutate! And it is weirdly obsessed with functions and how they compose, and in some sense that is all that matters.
