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.
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 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.
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.
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.
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.
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.
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.
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.
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.
Many apps show lots of data in a list, and allow users to filter that list by typing in a text view. In this article we’re going to build that in SwiftUI, then pull it out into a reusable component you can apply anywhere.
Most of the time the built-in iOS controls are great, but sometimes you want something just a little different. In this article I’m going to walk you through how you can take complete control over the way toggle switches work in SwiftUI, providing custom rendering and interactions.
One of the least obvious but most important clean ups lies in our use of Core Data, because right now we’re leaking data and also showing flat out wrong data. To fix these we need to use some more advanced Core Data, so let’s get into it…
There are many data structures in computing, but stacks are one of the most fundamental – they get used in so many places, often without us even realizing. Helpfully, they are also one of the easiest types to learn, which makes them a great starting point for this new series on data structures.
UserDefaults system lets us store small amounts of user data for our app, which might sound simple but it’s deceptively powerful. In this article I’ll show you the correct way to create initial preferences, how to share preferences across applications, how to synchronize data with iCloud, and why this is a case where property wrappers probably aren’t a good solution.
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.
Particle systems let us create special effects such as confetti, fire, smoke, rain, and snow, all by adjusting a range of inputs. In this article we’re going to build our own particle system entirely driven by SwiftUI, so you can easily add some sparkle to your apps.
We already looked at how to fetch decodable data using Combine, and also how to fetch and merge multiple sources of data. In this article we’ll tackle something even more complex: creating chained network requests, where the information retrieved from one request must be used to create multiple other requests.
ButtonStyle protocol is a great way to reuse designs across your app, to get a consistent look and feel everywhere. But they have one significant problem with animations, and in this article I’ll show you that problem in action, then walk you through how to fix it in a flexible way.
