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.

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.

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.

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.

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.

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.

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.

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.

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.

Custom sorting for items

56:13

ULTIMATE PORTFOLIO APP

Custom sorting for items

Our default sort for project items works well enough, but with a little extra work we can let users choose how to sort them. In this article I’m going to walk you through several different ways of approaching this problem, some that I think work well, and others not so much…

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.

Creating a StretchingHeader that sticks to the top of a view

18:35

CUSTOM SWIFTUI COMPONENTS

Creating a StretchingHeader that sticks to the top of a view

When users scroll beyond the top of a scroll view the default behavior is to show some empty space, but many apps prefer to show a stretchy header area instead. In this article I’ll show you how to build that SwiftUI, making an image that stays fixed to the top no matter what.

Documenting our code

41:58

ULTIMATE PORTFOLIO APP

Documenting our code

Good documentation describes not only what code does, but provides context on why it works a certain way, what assumptions you made, any optimizations you made, as well as describing subtleties in the implementation if you’re dealing with difficult code. In this article we’re going to be documenting our project for other developers and beyond!

Understanding generics – part 2

30:48

INTERMEDIATE SWIFT

Understanding generics – part 2

In this second tutorial on generics, we’re going to explore creating several different generic types, look at extending generics, and look at how we can apply our generics knowledge to create property wrappers.

Finding and fixing slow rendering

25:12

HIGH-PERFORMANCE APPS

Finding and fixing slow rendering

Instruments is a powerful tool for identifying performance problems, but in this article I’ll show you how to find code that slows down rendering in your app, causing slow scrolling, wasted CPU time, and more – all through the simulator.

Creating a spaceship operator

8:47

INTERMEDIATE SWIFT

Creating a spaceship operator

When it comes to learning operator overloading, there is one operator that Swift lacks, that many other languages have, and is genuinely useful. In this article I’ll show you how to build the spaceship operator in Swift – it’s surprisingly easy, and useful too.

Offering in-app purchases, part 2

38:01

ULTIMATE PORTFOLIO APP

Offering in-app purchases, part 2

Previously we added all the back-end work to make in-app purchases possible in our app. In this article we’re going to continue that work by implementing the user interface for our store, limiting the app itself, and also asking for user reviews.
