When you subscribe to the practice of test-driven development or just writing tests in general you’ll typically find that you’re going to be writing lots and lots of tests for pretty much everything in your codebase. This includes testing that varying inputs on the same function or on the same object result in expected behavior. […]

Swift testing is Apple’s framework for running unit tests in a modern and more elegant way than it was with XCTest, which came before it. This post is the first one in a series of posts that will help you start using Swift Testing in your projects. In this post, we’ll take a look at […]

The Swift testing framework is an incredibly useful tool that allows us to write more expressive tests with convenient and modern APIs. This is my first post about Swift Testing, and I’m mainly writing it because I wanted to write about something that I encountered not too long ago when I tried to use Swift […]

Code has dependencies. It’s something that I consider universally true in one way or another. Sometimes these dependencies are third party dependencies while other times you’ll have objects that depend on other objects or functionality to function. Even when you write a function that should be called with a simple input like a number, that’s […]

With iOS 18, we have the possibility to create mesh gradients. Mesh gradients are a really nice way to create very cool UI effects. In this post, we’re going to explore exactly what mesh gradients are, how we can use them, and how we can even animate them to look really cool. We’ll start off […]

Over the years, Apple has been putting tons of work into the SF Symbols catalog. With SF Symbols, we’re able to leverage built-in iconography that will look familiar to users while also fitting into the Apple ecosystem very nicely. The fact that there’s thousands of symbols to choose from makes it a highly flexible and […]

Once you start migrating to the Swift 6 language mode, you’ll most likely turn on strict concurrency first. Once you’ve done this there will be several warings and errors that you’ll encounter and these errors can be confusing at times. I’ll start by saying that having a solid understanding of actors, sendable, and data races […]

When you create a new Swift Package in Xcode 16, the Package.swift contents will look a bit like this: // swift-tools-version: 6.0 // The swift-tools-version declares the minimum version of Swift required to build this package. import PackageDescription let package = Package( name: "AppCore", products: [ // Products define the executables and libraries a package […]
