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.

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.

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.

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.

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.

Interview questions: Introduction

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…

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.

Understanding assertions

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.

Ultimate Portfolio App: Introduction

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.

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.

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.

Transforming data with map()

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!

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.

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.

What process do you take to perform code review?

2:10

INTERVIEW QUESTIONS

What process do you take to perform code review?

This sounds like it ought to be straightforward, but usually there’s an ulterior motive here: are you able to work well as part of a team?

Adding a meteor shower

25:55

REMAKING APPS

Adding a meteor shower

Large parts of Apple’s Weather app is about bringing little sparks of joy to an otherwise very serious, fact-driven experience, but none more so than the random little meteors that fly by on starry nights. They move so fast so you might be tempted to skip over them, but I think it’s definitely worth exploring and having some fun with!

Rendering a pie chart

25:37

RENDERING CHARTS IN SWIFTUI

Rendering a pie chart

Pie charts are a classic way of showing divided data visually, and they represent interesting challenges around sizing and angles. In this article we’ll build a complete pie chart view from scratch using SwiftUI, ensuring it works using animation, and also modify it to support donut-style charts too.

Getting the most from Canvas

23:20

ADVANCED SWIFTUI

Getting the most from Canvas

SwiftUI’s Canvas view is an extremely fast and efficient way to render custom graphics, but it’s also powerful – if you know what you’re doing you can unlock a huge amount of extra functionality to get the exact effect you’re looking for. Let’s look at six techniques here…

Designing a great model

34:35

ULTIMATE PORTFOLIO APP

Designing a great model

UPDATED: Almost always, the key to getting a great app is getting a great data model – deciding as early as you can what data you want to store, and how each piece relates to other pieces. So, we’re going to dive straight into Core Data!
