Ultimate Portfolio App: Introduction

ULTIMATE PORTFOLIO APP

FREE: Ultimate Portfolio App: Introduction

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.

Creating a WaveView to draw smooth waveforms

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.

Understanding generics – part 1

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.

How to use phantom types in Swift

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.

Creating a custom property wrapper using DynamicProperty

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.

Making the most of optionals

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.

Using memoization to speed up slow functions

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.

Shadows and glows

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.

Trees

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.

User-friendly network access

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.

Now for the real work…

ULTIMATE PORTFOLIO APP

Now for the real work…

Everything we’ve done so far has produced a serviceable app, although it does have a few bugs that we’ll address later. But before we address those, I want to change gear and focus on making our existing code better. This is where the real work begins!

Cleaning up Core Data

23:38

ULTIMATE PORTFOLIO APP

Cleaning up Core Data

Core Data’s optionals are quite different from Swift’s optionals, which makes them a little uncomfortable to work with. In this article I’m going to show you two ways of fixing this, which will help clear up our code nicely.

Creating a FlipView to provide a card flip effect

14:11

CUSTOM SWIFTUI COMPONENTS

Creating a FlipView to provide a card flip effect

If you’re looking for a simple and fun special effect to add to your code, I’ve got just the thing for you. In this article I’m going to walk you through building a FlipView with SwiftUI, which will encapsulate how to move between a front view and a back view using a 3D flip animation.

Controlling views using the accelerometer

39:03

SWIFTUI SPECIAL EFFECTS

Controlling views using the accelerometer

Reading device motion and orientation is a fast and slightly magical way to incorporate the real world into your apps, and can do a huge amount to add a little spark of delight to your UI. In this article I’m going to show you how easy it is to control SwiftUI layouts using the accelerometer, and give you a few ideas for special effects.

Parsing XML the easy way

16:43

WORKING WITH DATA

Parsing XML the easy way

Although we mostly prefer JSON for data transfer, many major languages make it easy to parse and traverse XML documents. Swift does not, but that’s something we can fix in under a 100 lines of code by writing our own implementation of MiniDOM – Python’s lightweight implementation of the document object model.

Storing your code somewhere safe

21:32

ULTIMATE PORTFOLIO APP

Storing your code somewhere safe

At this point we have something very simple working, so now is a great time to stash your code away somewhere safe using source control. If you already know how to use Git then you’re welcome to skip this part.

Why opaque return types are so important

12:19

ADVANCED SWIFT

Why opaque return types are so important

Opaque return types are a powerful feature in Swift, and are also critically important for writing SwiftUI. In this article I’ll be explaining how they work, and why they give us more power than returning a simple protocol.

Advanced string interpolation, part one

24:23

ADVANCED SWIFT

Advanced string interpolation, part one

String interpolation is easy, right? Wrong! String interpolation is actually a huge power feature in Swift, and we have a massive array of functionality on hand to help us customize it. In this article I’ll show you just how much control we have, and how to use that control to make your code easier to read.

Editing projects

19:02

ULTIMATE PORTFOLIO APP

Editing projects

Editing projects is much like editing items, but because a good portfolio project should show off a range of skills we’re going to bring in grids, alerts, tap gestures, and more.

Identifying performance hot spots with Time Profiler

HIGH-PERFORMANCE APPS

Identifying performance hot spots with Time Profiler

Instruments gives us a range of tools for finding performance problems, and in this article we’ll be looking at how the Time Profiler instrument can point out problems in seconds.
