Articles and podcasts about Swift development, by John Sundell.
Presented by the Genius Scan SDK
Swift Clips, videos, and recordings of my conference talks about Swift development.
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 video, we’ll take a look at three different ways to manage the URLs and server endpoints that a Swift app is communicating with, and the sort of pros and cons that come with each approach.
Let’s take a look at how SwiftUI’s various stacks and spacers can be used to achieve many kinds of flexible, adaptive layouts with very little code. While SwiftUI does include several more advanced layout APIs, stacks and spacers are a great starting point for most UIs.
In the second episode of Swift Clips, we’ll take a look at the DispatchQueue API, and how we can use it to write concurrent and asynchronous code in Swift.
Welcome to Swift Clips — a new series of shorter videos showcasing interesting and useful Swift tips and techniques. In this first episode we’ll take a look at first class functions, which is a language feature that enables us to use functions in really powerful ways.
A look behind the scenes of Swift by Sundell, as well as a preview and live demo of my suite of static site generation tools.
My opening keynote from Pragma Conference 2019, which is all about preparing for change, investing in learning and experimentation, and how to make the most out of our journey as developers.
Deploying generics in a more gentle fashion — to make a code base simpler, not more complicated.
How I make tech decisions, and the various phases that I go through in order to make decisions that have a higher chance of standing the test of time.
How I use the power of curiosity to fuel my learning process, to improve the quality of my code, and to build things that at first might seem impossible.
How I design systems and architectures for apps — going beyond design pattern acronyms and into the realm of system design.
In this talk I give my top tips on how almost anything and everything can be prototyped — from ideas and concepts, to new features and designs.
How I tactically deploy UI tests to verify certain features, and how they can even be used as a development tool.
How and why I started sharing large parts of my work with the community, and my top tips on how to get started with open source, blogging and podcasting.
In this talk, we’ll go beyond animations and take a look at how Core Animation’s many powerful features can enable different kinds of high-performance rendering.
In this talk I give an introduction to game development, for app developers who want to start making games on Apple’s platforms.
How API design isn’t only something to consider when building frameworks and SDKs, but how it also can be a fantastic tool to improve the architecture of apps.
A talk about a few different techniques that I use to build animations for iOS, and how these techniques can be used to implement nice and smooth workflows for both developers and designers.
An introduction to Swift scripting, and why I think Swift is an awesome language for scripting.
In this talk I spoke about unit testing in Swift, and gave several tips on how code can be refactored to become much more testable.
