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.

Using memoization to speed up slow functions

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

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

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.

Sorted arrays

DATA STRUCTURES

Sorted arrays

A sorted array is one that retains a correct sort order no matter how and when you add items. Although this sounds simple enough to implement, in this article you’ll see that it’s actually quite fun to explore because there are a number of interesting challenges we’ll face.

Creating a particle system in SwiftUI

SWIFTUI SPECIAL EFFECTS

Creating a particle system in SwiftUI

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.

The ultimate Box type

The ultimate Box type

Boxing allows us to wrap up a struct in a class, to make it easy to share in several places. I’ve touched on boxing briefly previously, but here I want to take the concept much further to add useful protocol conformances that really powerful up its usefulness.

Building a RadialMenu that shows many buttons around it

Building a RadialMenu that shows many buttons around it

Sometimes pressing a button needs to present more buttons, and although you can use an action sheet for this it’s not ideal because it appears in a different location. In this article I’ll show you how to build a radial menu, which solves the problem by presenting a ring of buttons close to the user’s touch.

Remaking the Tips app

REMAKING APPS

Remaking the Tips app

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.

Animating buttons using ButtonStyle

INTERMEDIATE SWIFTUI

Animating buttons using ButtonStyle

SwiftUI’s 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.

Understanding generics – part 1

INTERMEDIATE SWIFT

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 TabbedSidebar that handles both tab view and sidebar

INTERMEDIATE SWIFTUI

Creating a TabbedSidebar that handles both tab view and sidebar

If you want your app to work well on larger devices, you need to support both a sidebar and a tab bar for your primary navigation. In this video I’ll show you how to build one simple SwiftUI component that transitions between both smoothly.

Creating a spaceship operator

Creating a spaceship operator

When it comes to learning operator overloading, there is one operator that Swift lacks, that many other languages have, and is genuinely useful. In this article I’ll show you how to build the spaceship operator in Swift – it’s surprisingly easy, and useful too.

Creating a LongPressButton to trigger after delay

In this article I’m going to walk you through building a LongPressButton with SwiftUI, which will requires users to press and hold for a second before it’s triggered.

Removing optionals from your code

INTERMEDIATE SWIFT

Removing optionals from your code

Optionals are one of Swift’s most powerful features, letting us write code that is guaranteed to be safe as long as we check and unwrap them carefully. However, more often than not I prefer to avoid optionals as often as possible, and in this article I’ll outline some approaches for doing so.

Ordered sets

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.

Handling names correctly

18:50

MAKING THE MOST OF FOUNDATION

Handling names correctly

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.

Customizing ProgressView using ProgressViewStyle

INTERMEDIATE SWIFTUI

Customizing ProgressView using ProgressViewStyle

SwiftUI’s ProgressView gives us control over showing determinate or indeterminate progress, but it’s a bit dull – just a thin line and an activity spinner. Fortunately, we also get the ProgressViewStyle protocol so we can build entirely custom progress views, and in this article I’ll show you how it’s done.

Creating a StretchingHeader that sticks to the top of a view

CUSTOM SWIFTUI COMPONENTS

Creating a StretchingHeader that sticks to the top of a view

When users scroll beyond the top of a scroll view the default behavior is to show some empty space, but many apps prefer to show a stretchy header area instead. In this article I’ll show you how to build that SwiftUI, making an image that stays fixed to the top no matter what.

Existentials and type erasure – part 1

ADVANCED SWIFT

Existentials and type erasure – part 1

Type erasure helps us solve difficult type system problems by purposefully discarding some information. In this article we’ll look at what the underlying problem is and how Swift solves it, and in the second part we’ll continue on to look at how we can build type erasure ourselves.
