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.
14:20
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.
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.

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.
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.
6:22
INSIDE SWIFT
FREE: Introduction – please watch!
The Inside Swift series is designed to explore Swift's own source code, so you can better understand how it works and also pick up techniques you can apply to your own code.
3:54
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…
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.
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.
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.
39:03
SWIFTUI SPECIAL EFFECTS
FREE: Controlling views using the accelerometer
Reading device motion and orientation is a fast and slightly magical way to incorporate the real world into your apps, and can do a huge amount to add a little spark of delight to your UI. In this article I’m going to show you how easy it is to control SwiftUI layouts using the accelerometer, and give you a few ideas for special effects.
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.
2:16:15
LIVE STREAMS
FREE: Brush & Bark
In this stream we're going to build a website in Swift, using a free, open-source framework I produced called Ignite. It's designed to be familiar for SwiftUI developers, so hopefully you can see the appeal!
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!
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.
11:03
ULTIMATE PORTFOLIO APP
FREE: Ultimate Portfolio App: Introduction
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.
23:09
LEARN SOMETHING NEW
FREE: The pitfalls of string bridging
Swift's strings are designed to work flawlessly with languages around the world, but sometimes – just sometimes – you need to be careful using them. Let's explore why…
31:55
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.
11:12
CUSTOM SWIFTUI COMPONENTS
Creating an AccessibleStack that flips stack axis based on Dynamic Type
There are several times when you might want to flip between a HStack and VStack, but one useful option is to look at the Dynamic Type size. Apple uses this itself to switch list rows to a vertical layout when using larger fonts, and in this tutorial I’ll show you how it’s done.

EVENTS
Sorting, filtering, and relationships with SwiftData
When it comes to sorting our data, SwiftData has two approaches: the trivial version that works great in a WWDC video and a handful of small projects, and a more complex version that is much more indicative of the kinds of apps you’ll be building in real life.
