FUNCTIONAL PROGRAMMING
FREE: Functional programming in Swift: Introduction
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.
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.
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.
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.
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.
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.
3:54
INTERVIEW QUESTIONS
FREE: Interview questions: Introduction
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…
11:03
ULTIMATE PORTFOLIO APP
FREE: Ultimate Portfolio App: Introduction
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.
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.
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.
27:33
INTERMEDIATE SWIFT
FREE: Understanding assertions
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.
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.
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.
42:32
FUNCTIONAL PROGRAMMING
FREE: Transforming data with map()
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!
1:54
INTERVIEW QUESTIONS
What open source projects have you contributed to?
This question comes up a lot, but I’m always wary of it because it places a lot of emphasis on unpaid work out of hours, which particularly affects people who already have extra responsibilities caring for children or elders.
54:14
LIVE STREAMS
List Buddy
In this article we’re going to build a command line utility using Apple’s excellent Argument Parser library. The app we’ll build sorts lists of data in various ways – it’s a nice and simple project that allows us to focus firmly on Argument Parser.
15:34
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.
22:06
ULTIMATE PORTFOLIO APP
Questions and answers, part 1
UPDATED: As folks have worked their way through the series so far, they’ve sent in various questions about implementation choices and more. In this article I want to address the most common questions asked so far, so that everyone can benefit.
53:37
REMAKING APPS
Creating a day/night cycle
One of the most beautiful parts of the Weather app is the way it smoothly transitions between day and night – it doesn’t just go from black to blue, but instead mimics both sunrise and sunset, smoothly animating between the two. In this tutorial we’re going to recreate that same effect in our own app.
56:53
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.
