Swift enums are among the most flexible tools available in the language. Using them as lightweight view models is a delight.

Sometimes, you just want some leniancy with codable. Here's how I get it.

Sometimes, you just need to persist some dumbed down data. Here's a few ways to do it.

Swift has a useful mechanism to generate random values. Today, let's see how we can plug in `SystemRandomNumberGenerator` for our own types.

It's not a groundbreaking pattern, but it pays to mask third-party code. Here's how I do it.

Codable is impressive, but it bails out quickly if .json doesn't appear exactly how it expects. Here's how I cleaned things up to pinpoint errors quickly.

Morphology, or for mere humans - the study of the many forms of words, is ripe with interesting programming applications. Let's take a look at a few of them.

The world lives on API responses. That means, we live in Codable modeled off JSON, so here's how I quickly built models using pretty printed String dumps.

Every codebase under the sun on God's green earth uses print statements to wrangle bugs. Let's look at the tools that Swift has for such cases.

Another core piece of functionality arrived in Swift 5.1 - built in diffing. Let's take a look.

Enumerations provide clarity and intent. Some change and yet others remain stagnant, and now we program effectively for either case.

Attributes can keep code clean and conscise without much effort. Today, let's cover some common, and uncommon, use cases.

Swift has quite a few keywords. Let's look at every single one, what it does and provide a code sample.

Interop is required in the world we live in. Here's an attribute in Swift that can help make things easier.

It's an attribute you've seen hanging over closures. Let's dive into what it means, or more specifically - meant.

The Swift Stand Library offers up several differeny ways to work with arrays. From sorting to sifting, almost every use case is covered efficiently.

More than just an anonymous function, Swift's closures are extremely versatile. One such use case for them is initialization.

Selectors are a part of iOS development daily. They can also be a common source of frustrating bugs, but #keyPath is here to help.

Our favorite open source language is changing at a rapid pace. Here, we'll check out some of my favorite additions that landed in Swift 3.

Abstraction is a tent pole component of modern programming. Swift's robust tooling for access control can help us enforce it.

Swift offers us several novel ways to refactor our code. Follow along as we embark on such a task on some fictional code.

Automatic reference counting debuted several years ago and ushered in a new era of memory management. But, how does it work with Swift?

If you're coming from Objective-C or are new to Swift, the way its initialization works can be confusing. Diving into the particulars is a worthwhile effort.

It's possible to enhance a wide family of objects with protocol extensions. Today we'll try and see how its possible.

Option Sets solve a large swath of problems, but you may not think to use them at first. Looking at how they work and why their useful might change your mind.

Javascript and...Swift? It works better than you might think, and for more than just parlor tricks.

Dealing with errors is usually a developer's favorite task to procrastinate against. But it shouldn't be, and even though Swift's inplementation is differnt - it's robust.

More than an _if_ statement, this simple construct makes code safer and readable. But when do you use one or the other?

More than an _if_ statement, this simple construct makes code safer and readable. But when do you use one or the other?

Pattern matching with Swift yields concise code when it otherwise might be a bit more convoluted. Here's how it works.

The infamous WWDC session introduced us to 'Protocol Oriented Programming'. Really, though - what is it?

Swift goes to great lengths to ensure values are initialized before they are used. The reasons how vary from API design to the way LLVM works - let's chat about this process cal...

We've now hit the inflection point where your Objective-C projects must mix with Swift, or vice-versa. Here's how my first experience with it went.

The boolean variable, perhaps the most simple implementation in Computer Science - or is it? Swift's version can do more than just spit out 0 or 1.

The array is a beautiful cornerstone of data structures, but sometimes we call upon its close cousin - the set. Here's how Swift's version works.

Integers are used in almost every iOS app. With Swift, they've become even more useful.

It's one of the first thing green programmers learn - looping and iteration. Swift has made it easy and versatile.

We'd all just as soon let the compiler do all the work, but sometimes casting is unavoidable. Here's how it can be used with Swift.

Tuples can be a short stand in for tiny data constructs. When used properly, they can make your code a bit more opportunistic.
