How to use phantom types 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.

Creating a WaveView to draw smooth waveforms

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.

User-friendly network access

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.

Creating a custom property wrapper using DynamicProperty

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.

Trees

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.

Ultimate Portfolio App: Introduction

14:17

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.

Understanding generics – part 1

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.

Making the most of optionals

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.

Using memoization to speed up slow functions

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.

Shadows and glows

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.

Making your app accessible

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.

Linked lists

29:22

DATA STRUCTURES

Linked lists

If there’s one data structure they just love teaching you at school, it’s linked lists. In this article we’re going to look at why linked lists are so appealing, walk through how to build a linked list with Swift, and look at an alternative approach using enums.

Instant sync and save

16:31

ULTIMATE PORTFOLIO APP

Instant sync and save

Rather than calling update() when our view disappears, what we really want to do is update the object before the disappear happens. In this article I’ll show you the SwiftUI native way of doing this, then walk you through an alternative that I prefer.

Storing preferences efficiently

32:42

MAKING THE MOST OF FOUNDATION

Storing preferences efficiently

Apple’s UserDefaults system lets us store small amounts of user data for our app, which might sound simple but it’s deceptively powerful. In this article I’ll show you the correct way to create initial preferences, how to share preferences across applications, how to synchronize data with iCloud, and why this is a case where property wrappers probably aren’t a good solution.

Questions and answers, part 1

24:31

ULTIMATE PORTFOLIO APP

Questions and answers, part 1

As folks have worked their way through the series so far, they’ve sent in various questions about implementation choices and more. In this article I want to address the eight most common questions asked so far, so that everyone can benefit.

Creating a LongPressButton to trigger after delay

16:02

CUSTOM SWIFTUI COMPONENTS

Creating a LongPressButton to trigger after delay

In this article I’m going to walk you through building a LongPressButton with SwiftUI, which will requires users to press and hold for a second before it’s triggered.

Building a RadialMenu that shows many buttons around it

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.

Measuring performance

17:57

ULTIMATE PORTFOLIO APP

Measuring performance

Although our project doesn’t do anything particularly performance intensive, having a great portfolio app means you should at least attempt to demonstrate you understand how performance tests work. In this chapter we’ll add just such a test to our project, to make sure our award counting work is fast.

Flood fill path finding

30:31

ALGORITHMS

Flood fill path finding

The flood fill approach to path finding is one of the easiest to learn, works great in games with small maps, and is also commonly used in software – filling a picture with color, for example. In this article I’ll walk you through how the algorithm works, and help you build a visual representation of it in action.

Questions and answers, part 2

46:09

ULTIMATE PORTFOLIO APP

Questions and answers, part 2

I’ve had a whole bunch more questions sent in from readers, covering Core Data, property wrappers, localization, and more, so let’s dive into them with some code examples.
