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.

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.
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.

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.

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.

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.
33:12
ULTIMATE PORTFOLIO APP
FREE: Making your app accessible
It is my firm belief that every iOS app should be usable to everyone, and putting in the work to make your app function well no matter who is using it says a lot about the kind of developer you are.

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.
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.
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.
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!

SOLUTIONS
FREE: Challenge 1: Converter
This early challenge day asks you to build a converter app that’s able to move between any two similar units, such as kilometers and miles. Let’s solve it now, then we’ll take it further, and then we’ll take it even further…
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.
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.
20:24
ADVANCED SWIFT
Making the most of optionals – part 2
I already introduced how the internals of optionals work, including how they use conditional conformance and how to avoid infinitely sized structs. In this video I’m going to go further as we look at how our knowledge of Optional can be translated to Result, why it’s so important that optionals are functors and monads, and more.

WeSplit
There are three challenges for WeSplit, including adding section headers and showing a grand total. Let’s solve them now…

ULTIMATE PORTFOLIO APP
Counting Core Data results
Now that we’ve designed a basic awards UI, we can bring it to life with some Core Data queries to determine which awards have actually been earned.

Moonshot
This challenge asks you to add some extra text to the mission view, break up at least two SwiftUI views, then, for something harder, allow the user to move between a grid and a list for missions. Let’s tackle it now…

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.
