ULTIMATE PORTFOLIO APP
Adding Sign in with Apple
We’re attaching an owner name to projects, but right now it’s always hard-coded to “TwoStraws”. In this step we’re going to fix that using Sign in with Apple, which authenticates users securely. This needs to be done carefully, but the end result is really nice as you’ll see! Continue Reading >

ULTIMATE PORTFOLIO APP
Querying data from iCloud
In the previous step we added the ability to upload projects and items to iCloud, then used the iCloud Dashboard to check the data had arrived safely. In this step we’re going to load shared projects, and let users browse them. Continue Reading >

ULTIMATE PORTFOLIO APP
Storing data in iCloud
Now that our project is all ready for expansion, our first step will be to let users upload projects to iCloud so later on other users can view them and even comment on them. We’ll approach this in a simple way at first, but we’ll come back for improvements later. Continue Reading >

ULTIMATE PORTFOLIO APP
Upgrading iCloud
We’re about to do a fair chunk of work integrating CloudKit, Sign in with Apple, and Apple Pay into our app, but the first step to success is to make a handful of small changes to our app to ensure it will all work well, and also fix a few long-standing bugs. Continue Reading >

REMAKING APPS
Remaking the welcome screen
Few things in SwiftUI are quite so easy and yet quite so rewarding as rebuilding Apple’s welcome screens. In this article we’ll do just that, making it flexible enough to adapt easily for your own apps. Continue Reading >

Barking with Swift
To celebrate the 1-year anniversary of Hacking with Swift+, here is a collection of times my dogs were convinced they were the real stars of the show. I’ve uncropped my webcam for maximum dog action! Continue Reading >

FUNCTIONAL PROGRAMMING
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! Continue Reading >

ULTIMATE PORTFOLIO APP
Creating a second widget
In this follow-on article we’re going to up our widget game by adding a second, more complex widget and exploring some configuration options that help our widgets work better on-screen. Continue Reading >

ULTIMATE PORTFOLIO APP
Creating a simple widget
Widgets allow users to place parts of our app right on their Home Screen, which is both deeply powerful and deeply personal. In this article we’re going to start by doing all the app configuration required to make widgets function, then add a simple widget for our app to show that everything works. Continue Reading >

FUNCTIONAL PROGRAMMING
Functions as first-class types
If I were to boil functional programming down to just two rules, the second rule would be this: functions are first-class types, and should be passed around like any other kind of data. In this article we’re going to explore what that means, and what power it unleashes… Continue Reading >

FUNCTIONAL PROGRAMMING
Building with pure functions
If I were to boil functional programming down to just two rules, the first one would be this: prefer to write pure functions as often as you can. What are pure functions, and why would you want them? Let’s start by exploring that in detail… Continue Reading >

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. Continue Reading >

ULTIMATE PORTFOLIO APP
Integrating with Shortcuts
Shortcuts let users access quick commands from our app elsewhere in the system, as well as chaining them to build complex commands, or even asking Siri to trigger one directly. In this article we’re going to add one to our app, and I think you’ll be amazed how little work it takes! Continue Reading >

ULTIMATE PORTFOLIO APP
Adding a Quick Action to our icon
Quick Actions let users long-press on our app’s icon on the Home Screen to show a list of actions they can perform immediately. In this article we’re going to add a quick action to create a new project in one step – it’s more work than you might think! Continue Reading >

Questions and answers, part 3
I’ve had a whole bunch more questions sent in from readers, covering testing, haptics, Spotlight, and more, so let’s dive into them with code examples. Continue Reading >

ALGORITHMS
A* path finding
The A* algorithm for path finding is not the perfect way to find an optimal route between two nodes in a graph, but it is either the best or darned close most of the time and that makes it a fantastic one to learn for both games and apps alike. Continue Reading >

ULTIMATE PORTFOLIO APP
Offering in-app purchases, part 2
Previously we added all the back-end work to make in-app purchases possible in our app. In this article we’re going to continue that work by implementing the user interface for our store, limiting the app itself, and also asking for user reviews. Continue Reading >

ULTIMATE PORTFOLIO APP
Offering in-app purchases, part 1
Although many apps work great when paid for up front, many more work better when using a freemium model – you get lots of downloads of a free app, then charge for some kind of premium service. In this article we’re going to prepare to limit our app unless the user has paid for an unlock, but we’ll be using a flexible approach you can adapt easily. Continue Reading >

ULTIMATE PORTFOLIO APP
Adding local notifications
Local notifications allow us to set reminders for the user without ever needing to send data off the device. In this article we’re going to add these notifications to our app, so that users can be reminded to work on specific projects. Continue Reading >

ULTIMATE PORTFOLIO APP
Integrating with Spotlight
In this article we’re going to make Spotlight store our app’s data, meaning that the user can search for items right from their iOS Home Screen. If you intend to follow the Widget or shortcut sections of this course later on, you should follow this article first. Continue Reading >
