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.

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.

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.

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.

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.

Functional programming in Swift: Introduction

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.

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.

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.

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.

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.

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.

Integrating with Shortcuts

10:40

ULTIMATE PORTFOLIO APP

Integrating with Shortcuts

Shortcuts let users access quick commands from our app elsewhere in the system, as well as chaining them to build complex commands, or even asking Siri to trigger one directly. In this article we’re going to add one to our app, and I think you’ll be amazed how little work it takes!

UI Testing with SwiftUI

40:37

ULTIMATE PORTFOLIO APP

UI Testing with SwiftUI

Even after writing stacks of unit tests, chances are your test coverage is still well below 40%. Those units tests are really important, but if you really want great test coverage you need to add some UI tests and that’s exactly what we’re going to work on here.

Finishing ProjectsView

22:32

ULTIMATE PORTFOLIO APP

Finishing ProjectsView

At this point our main list view is almost done, but before we’re finished we’re going to add some icons, make landscape mode work better, and even fix a rather nasty deletion bug.

Organizing the project itself

21:40

ULTIMATE PORTFOLIO APP

Organizing the project itself

We have one last easy task before we look at something trickier, which is to organize the Xcode project itself. Here I’m going to show you two different approaches so you can contrast them yourself, then explain which I prefer and why.

Linting our code

35:00

ULTIMATE PORTFOLIO APP

Linting our code

Code is designed to be read far more often than it is written, and one of the simplest ways of making code easier to read is to make it uniform – to make sure your code follows a simple style, so your brain can focus less on spacing and naming and more on understanding how the code actually works.

Rendering a line chart

28:41

RENDERING CHARTS IN SWIFTUI

Rendering a line chart

Line charts come in a couple of different forms, but they share the same goal of visualizing a change of value over time. In this article we’ll look at building a customizable line chart from scratch in SwiftUI.

Testing extensions

26:04

ULTIMATE PORTFOLIO APP

Testing extensions

Our project has three extensions that add functionality to Apple’s own code, and we need to treat these carefully – we don’t own them, so their behavior might change at any point in the future. So, in this article we’re going to write tests for the extensions we created, making sure they work correctly every time.

Queues and deques

28:18

DATA STRUCTURES

Queues and deques

Now that we’ve covered stacks and linked lists, queues and deques ought to be easier. In this article we’ll build both data structures in just a few lines of Swift, then explore interesting additions such as contains().
