Interview questions: Introduction

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…

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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!

Making your app accessible

16:13

ULTIMATE PORTFOLIO APP

Making your app accessible

UPDATED: 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.

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.

What is the purpose of NotificationCenter?

2:09

INTERVIEW QUESTIONS

What is the purpose of NotificationCenter?

Apple’s NotificationCenter class implements the observer pattern from the Gang of Four book on design patterns, allowing any number of objects be notified when a specific event happens. But to answer this question well, you need to go beyond theory and focus on when it’s actually used.

Dice Off

1:48:38

LIVE STREAMS

Dice Off

In this article we’re going to build a simple strategy game for iPad, using SwiftUI and SF Symbols. We’ll start out with it being a two-player game, but later on we’ll build a simple AI to make it work just as well as a one-player game.

Instant sync and save

11:39

ULTIMATE PORTFOLIO APP

Instant sync and save

UPDATED: Right now we trigger a save when our user takes a dramatic action such as adding a tag or deleting an issue, but we don’t want to trigger a save for every letter they press while editing an issue title. So, how can we make sure data is safe while also avoiding too much work?

List Buddy

54:14

LIVE STREAMS

List Buddy

In this article we’re going to build a command line utility using Apple’s excellent Argument Parser library. The app we’ll build sorts lists of data in various ways – it’s a nice and simple project that allows us to focus firmly on Argument Parser.
