DATA STRUCTURES
FREE: Trees
Trees are an extraordinarily simple, extraordinarily useful data type, and in this article we’ll make a complete tree data type using Swift in just a few minutes. But rather than just stop there, we’re going to do something quite beautiful that I hope will blow your mind while teaching you something useful.

INTERMEDIATE SWIFTUI
FREE: Creating a custom property wrapper using DynamicProperty
It’s not hard to make a basic property wrapper, but if you want one that automatically updates the body property like @State you need to do some extra work. In this article I’ll show you exactly how it’s done, as we build a property wrapper capable of reading and writing documents from our app’s container.
14:26
NETWORKING
FREE: User-friendly network access
Anyone can write Swift code to fetch network data, but much harder is knowing how to write code to do it respectfully. In this article we’ll look at building a considerate network stack, taking into account the user’s connection, preferences, and more.
23:07
ADVANCED SWIFT
FREE: Making the most of optionals
Swift’s optionals are implemented as simple enums, with just a little compiler magic sprinkled around as syntactic sugar. However, they do much more than people realize, and in this article I’m going to demonstrate some of their power features that can really help you write better code – and blow your mind along the way.
11:03
ULTIMATE PORTFOLIO APP
FREE: Ultimate Portfolio App: Introduction
UPDATED: While I’m sure you’re keen to get started programming immediately, please give me a few minutes to outline the goals of this course and explain why it’s different from other courses I’ve written.
42:32
FUNCTIONAL PROGRAMMING
FREE: Transforming data with map()
In this article we’re going to look at the map() function, which transforms one thing into another thing. Along the way we’ll also be exploring some core concepts of functional programming, so if you read no other articles in this course at least read this one!
19:50
SWIFTUI SPECIAL EFFECTS
FREE: Shadows and glows
SwiftUI gives us a modifier to make simple shadows, but if you want something more advanced such as inner shadows or glows, you need to do extra work. In this article I’ll show you how to get both those effects and more in a customizable, flexible way.
32:08
CUSTOM SWIFTUI COMPONENTS
FREE: Creating a WaveView to draw smooth waveforms
In this article I’m going to walk you through building a WaveView with SwiftUI, allowing us to create beautiful waveform-like effects to bring your user interface to life.
36:18
HIGH-PERFORMANCE APPS
FREE: Using memoization to speed up slow functions
In this article you’ll learn how memoization can dramatically boost the performance of slow functions, and how easy Swift makes it thanks to its generics and closures.
27:33
INTERMEDIATE SWIFT
FREE: Understanding assertions
Assertions allow us to have Swift silently check the state of our program at runtime, but if you want to get them right you need to understand some intricacies. In this article I’ll walk you through the five ways we can make assertions in Swift, and provide clear advice on which to use and when.
24:11
ADVANCED SWIFT
FREE: How to use phantom types in Swift
Phantom types are a powerful way to give the Swift compiler extra information about our code so that it can stop us from making mistakes. In this article I’m going to explain how they work and why you’d want them, as well as providing lots of hands-on examples you can try.
20:01
INTERMEDIATE SWIFT
FREE: Understanding generics – part 1
Generics are one of the most powerful features of Swift, allowing us to write code once and reuse it in many ways. In this article we’ll explore how they work, why adding constraints actually helps us write more code, and how generics help solve one of the biggest problems in Swift.

INTERVIEW QUESTIONS
FREE: Interview questions: Introduction
Getting ready for a job interview is tough work, so I’ve prepared a whole bunch of common questions and answers to help give you a jump start. But before you get into them, let me explain the plan in more detail…
6:52
FUNCTIONAL PROGRAMMING
FREE: Functional programming in Swift: Introduction
Before you dive in to the first article in this course, I want to give you a brief overview of our goals, how the content is structured, as well as a rough idea of what you can expect to find.
15:50
ULTIMATE PORTFOLIO APP
Testing the basics
UPDATED: At last it’s time to start writing tests for our project, which means a little bit of setup work backed by writing our first couple of tests – we’ll take this slow initially, but lay down a good foundation for future tests.
32:13
CUSTOM SWIFTUI COMPONENTS
Building a RadialMenu that shows many buttons around it
Sometimes pressing a button needs to present more buttons, and although you can use an action sheet for this it’s not ideal because it appears in a different location. In this article I’ll show you how to build a radial menu, which solves the problem by presenting a ring of buttons close to the user’s touch.
1:59
INTERVIEW QUESTIONS
How do you stay up to date with changes in Swift?
This is particularly important in the world of Apple development because all their major operating systems change every year, Swift sees significant changes two or three times a year, and new devices are shipping regularly.
36:20
SOLUTIONS
High Rollers
This challenge asks you build an app that simulates random dice rolls on behalf the user, adding haptic feedback to bring it to life, and permanent storage for later reference. Let’s tackle it now…
2:44
INTERVIEW QUESTIONS
What do you think is a sensible minimum iOS deployment target?
You can go for a simple “current version minus 1” answer here, but it won’t do you much good – talk about specific features you care about, or perhaps even specific bugs that got fixed.
1:25:49
LIVE STREAMS
Animation Explorer
In this stream we’re going to build an app to help visualize animation curves. That means combining SwiftUI and Swift Charts to create something simple but beautiful – this leverages a real range of techniques at once!
