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.

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.

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.

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.

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.

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

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.

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.

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.

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.

Using dates safely and effectively

18:36

MAKING THE MOST OF FOUNDATION

Using dates safely and effectively

Working with dates in software is hard, and if you don’t understand why then think about time zones, think about leap years, or think about how it’s the year 2563 in the Thai calendar. Apple gives us many tools for making them easier but they can be hard to discover, so in this article I’m going to try to provide some clear guidance for what to use and when.

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…

@AppStorage, ProgressView, and documents

1:01:00

HACKING WITH SWIFT LIVE 2020

@AppStorage, ProgressView, and documents

In this part we’re going to start by looking at storing app information in UserDefaults, then move on to showing progress with ProgressView, and finally loading and saving documents.

Parsing XML the easy way

16:43

WORKING WITH DATA

Parsing XML the easy way

Although we mostly prefer JSON for data transfer, many major languages make it easy to parse and traverse XML documents. Swift does not, but that’s something we can fix in under a 100 lines of code by writing our own implementation of MiniDOM – Python’s lightweight implementation of the document object model.

Existentials and type erasure – part 2

41:03

ADVANCED SWIFT

Existentials and type erasure – part 2

In the first part of this tutorial we looked at the underlying problem that type erasure is trying to solve, and tried out Swift’s approach using AnySequence. In this second part we’re going to adapt Swift’s own solution to get real type erasure for our own code.

Converting measurements safely

17:58

MAKING THE MOST OF FOUNDATION

Converting measurements safely

Apple’s Foundation framework makes it easy for us to convert any kind of measurement into any other kind of measurement. In this article I’ll show you how to make the most of these APIs, but also why it’s so useful that they work with Swift features such as operator overloading, plus important protocols such as Comparable, Equatable, and Codable.

Just for fun: weather forecasting

1:09:19

HACKING WITH SWIFT LIVE 2020

Just for fun: weather forecasting

Now you understand how widgets work, I want to give you a fun and simple task to experiment with. There’s no example solution here because this is just a sandbox for your ideas, but we’ll end up with a fun quiz to test what you learned.

Ordered sets

22:31

DATA STRUCTURES

Ordered sets

Arrays and sets have their own advantages and disadvantages, but what if we could combine them both to make an ordered set? We can! And in this article that’s exactly what we’ll do.
