This week’s article is about library development, and contains a few techniques and principles that can be good to keep in mind when designing and building reusable Swift libraries.
Let’s take a look at a number of techniques, patterns, and ways of structuring UI code that can help us get the very most out of Xcode’s SwiftUI-powered preview system.
On this special episode, John is joined by the entire team behind the award-winning apps Halide and Spectre, Apple’s 2019 App of the Year. Ben, Sebastiaan and Rebecca share their stories of how these apps came to life, how they’re working together between design and development, and how technologies like Computational Photography and Augmented Reality are influencing their work.
Kyle Lee, also known as Kilo Loco, joins John to go behind the scenes of Publish — the static site generator used to build Swift by Sundell. Also, how to make a code base accessible to new team members, learning from open source, getting started with Swift-based web development, and much more.
Testable code without any protocols.
Making it easy to observe a single value in a read-only fashion.
Adding more contextual information to test failures.
Let’s take a look at how Swift’s key paths work, and how they relate to functions — both in terms of what comes built into the language itself, and what kind of utilities that we can write ourselves to form some really nice convenience APIs.
Let’s take a look at the role that controllers play within the MVC design pattern, and how we can avoid some of the most common issues when working with them — particularly around how we can break up Massive View Controllers into smaller building blocks.
In this Basics article, let’s take a look at a few examples of the various kinds of properties that Swift supports, and what their characteristics are.
Combine is a really powerful reactive programming framework from Apple, but getting started with it can be quite difficult, so let’s go through the basics of its API and its core concepts.
