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.
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.
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.
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.
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.
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.
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.
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.
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.
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!
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.
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…
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.
We’ve added quite a bit of iCloud functionality in the last few tutorials, so before we’re done we need to clean up what we have so it’s a solid foundation we can build on. To start with, that means tackling removing data as well as we handling adding data.
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.
At this point we’ve looked at writing code using
await, using continuations to bridge old code, then optionally using
async let as well. Here we’re going to expand our concurrency knowledge to include tasks and task groups, which provide much more control over our work.
You can go for a simple “current version minus 1” answer here, but it won’t do you much good – talk about specific features you care about, or perhaps even specific bugs that got fixed.
There are lots of UI mistakes we can make in programming, but unless our bugs actually get in the way of functionality most users don’t care that much. But there is one exception, and we’re going to look at it here: in this article I’ll show you how to handle names correctly – the most personal data of all.
The last part of cleaning up CloudKit involves upgrading our Awards to include chat messages, updating our localization to include all the new UI we’ve added, and fixing a small SwiftUI bug – just enough to leave CloudKit in good shape before we move on.
