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.
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 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.
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.
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.
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!
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.
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.
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.
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.
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.
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.
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.
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…
In this article we’re going to look at how easy it is to rebuild the iOS lock screen. Yes, this isn’t hard, but along the way I think you’ll pick up a few cool SwiftUI tricks, including better date formatting, haptic buttons, and more.
A great answer should introduce property wrappers, then explain what @Published
does, give some examples, compare it against @State
, then bring in any extra real-world knowledge you can add around nuances or complexities.
Now we need to turn our eyes to the first significant piece of work porting to macOS: adjusting the Open and Closed tabs so they look and work better on macOS. This means adding some Mac-only modifiers and views, but it gives us a big step forward as you’ll see.
Labels are one of the simplest views in SwiftUI, but that doesn’t mean there isn’t a lot to explore. In this video I’ll walk you through how to build custom label styles, including adding animation effects triggered by hovering with the iOS trackpad.
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.
Widgets allow users to place parts of our app right on their Home Screen, which is both deeply powerful and deeply personal. In this article we’re going to start by doing all the app configuration required to make widgets function, then add a simple widget for our app to show that everything works.
