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 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.

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.

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.

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.

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.

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.

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.

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.

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.

Storing data in iCloud

31:23

ULTIMATE PORTFOLIO APP

Storing data in iCloud

Now that our project is all ready for expansion, our first step will be to let users upload projects to iCloud so later on other users can view them and even comment on them. We’ll approach this in a simple way at first, but we’ll come back for improvements later.

Implementing App Clips in a real app

1:01:00

HACKING WITH SWIFT LIVE 2020

Implementing App Clips in a real app

Now that you understand how App Clips work, in this part we’ll apply them to our Barking Lot app so you can see them in action with real code.

Counting Core Data results

20:34

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.

The pros and cons of operator overloading

23:37

ADVANCED SWIFT

The pros and cons of operator overloading

I’ve written about operator overloading previously, not least in my book Pro Swift, but in the article I want to go into more depth on the places where it’s really useful – and the places where it’s not such a good idea.

Remaking the Tips app

27:45

REMAKING APPS

Remaking the Tips app

In this article we’re going to look at how to rebuild the Tips app using SwiftUI, including how to make scrolling tabs of content, how to get a parallax scrolling effect, and more.

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.

Bringing MVVM into our SwiftUI project, part 1

43:39

ULTIMATE PORTFOLIO APP

Bringing MVVM into our SwiftUI project, part 1

The final major change we’re going to make to our project is to look at how it fits in with the MVVM design pattern. I left this one to last because it’s quite a jump from our previous work and in some respects SwiftUI even fights against it, but I do think it’s worth exploring so you can be sure your code is sound.

Creating a LongPressButton to trigger after delay

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.
