The differences between compactMap and flatMap explained with examples and a rule of thumb to decide whether you need map, flatMap or compactMap.

Many say "refactoring" to mean "rewriting." But here's an example showing refactoring in small steps, verifying each step with unit tests.

Our @richturton walks you through implementing a custom key strategy for coding types.

There are many ways to speed up a network request: compressing and streaming, caching and prefetching, reducing and inlining, connection pooling and multiplexing, deferring and backgrounding. And yet there’s one optimization strategy that both predates and…

In this tutorial, you’ll learn to use dynamic features in Swift to write clean code, create code clarity and resolve unforeseen issues quickly.

What the hell 🔥 is a Stateful ViewController? A Stateful ViewController is then name given by us to a ViewController that has many states…

In this article we'll talk about detecting directed cycles in edge weighted digraphs and we'll implement the solution in swift.

The documentation for the <code>CustomStringConvertible</code> protocol discourages accessing a value’s <code>description</code> property directly. Instead, you’re supposed to call <code>String(describing:)</code>. Why?

With each new release, Swift keeps getting better and better at creating compiler-generated implementations of common boilerplate. One such new feature in Swift 4.2 is the new CaseIterable protocol - that enables us to tell the compiler to automatically synthesize…

Usage of high-order functions like map and filter are very common in Swift projects, as they are simple algorithms that allow you to convert extensive ideas into simple one-liners. Unfortunately, they don't solve every issue - at least not in their default…

Making your Swift code more fun 🎉, magical ✨ and crunchier 👌

In this tutorial, I'll explain two examples of patterns in the "structural" category: facade and adapter. You will learn by building a simple Playgrounds project.

In this tutorial, you’ll create an app that uses audio playback, location updates, critical tasks, and background fetch to learn about the most common background modes.

Some tips for writing concise switch statements

Reviewing my foray into using Result for error handling in Swift, and my realization of a particular use case it solves well.

In this article, we’ll take a look at a portion of the ModelIO framework we haven’t used so far: materials. In previous articles, we’ve used ModelIO to do the heavy lifting of loa…

Getting Started This article is a quick introduction to how to use the Metal, MetalKit, and Model I/O frameworks in Swift. If you know your way around UIKit or Cocoa development, you should be able…

In the previous article, we wrote enough Metal code to get the spinning silhouette of a teapot on the screen, but that still leaves a lot to be desired as far as a “modern” app is conce…
