Does this subscription give me all your books?

The articles produced for Hacking with Swift+ are all new and exclusive to subscribers, but after subscribing for 18 months you'll also gain free online access to over a dozen of my books. This means your subscription grows as you do, making Hacking with Swift+ the largest and most comprehensive subscription around.

Can I share one account with my whole team?

No, this is not allowed – each member of your team needs their own subscription, just like they would need their own Netflix or Apple Music accounts. If you want your whole team to have a Hacking with Swift+ account, please change the number of licensed seats upwards from 1 when subscribing.

How is a team subscription different from an individual subscription?

When you subscribe with at least three seats, all members of your team gain immediate access to the Hacking with Swift reading library, rather than waiting 18 months – that's over a dozen of my books to maximise your team's learning.

What are the free gifts?

Each year of your subscription we'll mail out free gifts, as a thank you for supporting the site. These include pin metal badges, magnets, stickers, coasters, and more – we think you'll love them! If you take out an annual subscription, we send out your first year's gifts immediately.

What happens in the monthly live streams?

Every Hacking with Swift+ subscriber is invited to join my private monthly live streams on YouTube, where I build a complete app from scratch while answering questions along the way. This is your chance to get involved and explore projects being written live, and these streams are always hugely popular.

What happens if I miss a live stream?

All live streams are recorded, and posted onto the main Hacking with Swift+ site afterwards. Even better, they include a full transcript alongside, so if you prefer text tutorials to video tutorials you have that option.

How do I remove adverts from the site?

Every subscriber can enjoy an ad-free experience on Hacking with Swift – all you need to do is log in, and the site will automatically remove the adverts. To give you the fastest reading experience, we also remove the gray bar under the menu, plus the right-hand bar that sits next to every article.

Is Hacking with Swift+ suitable for absolute beginners?

If you're an absolute beginner you should start with my free 100 Days of SwiftUI course, which teaches you the fundamentals of Swift and SwiftUI. However, Hacking with Swift+ includes complete solutions to all the checkpoints and milestones in the 100 Days of SwiftUI series, making it the perfect companion as you're learning.

What's more, Hacking with Swift+ will grow with you once you've finished learning – it has a wide range of intermediate to advanced Swift techniques and tutorials that will keep pushing your skills further, no matter what your goal.

Some sites claim to have thousands of videos – why is HWS+ better?

Hacking with Swift+ focuses firmly on two things:

  1. Giving you the depth you need to get a strong grasp of each topic. Where other sites make hundreds of three or four minute videos that touch lightly on each subject, we prefer to go into much more detail – 20 or 30 minutes, and often longer – so you get to understand why things work as well as how.
  2. We teach Swift, Swift, and more Swift. We don't do Kotlin, we aren't interested in Dart, we won't try to squeeze in Flutter, and you won't find any React Native. That's not to say those other technologies aren't interesting, only that you're here to take your Swift skills further and that's exactly what we care about most.

How much does it cost?

Hacking with Swift+ costs $20 a month or $200 a year, per seat. Your membership includes all subscriber-only videos and articles available now and published in the future, for as long as your membership remains active. You can cancel your membership at any time, and your access will continue until your term ends.

What's the difference between Monthly and Yearly subscriptions?

Hacking with Swift+ is $20 per month, and you can cancel whenever you want. If you intend to work through many articles and really push your learning forward, you should consider the yearly subscription option, which is $200 for 12 months – a saving of $40.

Both tiers get access to exactly the same high-quality videos, articles, and source code. The only difference is that with the Yearly tier you save $40 every year, making it better value for money.

Are there exercises?

Yes! Many Hacking with Swift+ articles end with challenges to help you take your learning further – code to try, problems to solve, questions to consider, and more.

Why do I need a Hacking with Swift account?

Your Hacking with Swift account links your Gumroad purchase to this site, so we can unlock your subscription. This account also allows you to post to the forums if you want to.

Can I switch from a Monthly to Yearly subscription?

Yes, you can upgrade at any time, and we'll discount the annual subscription based on how much of your monthly subscription remains.

How can I cancel my subscription?

If at any point you want to cancel your Hacking with Swift+ subscription, you can do so directly through your Gumroad account. Your access to the subscriber-only content will remain active until your subscription term ends, at which point it will cease.

Will there be sales tax or VAT added to the price?

If you live in a country or state where tax is applied to digital purchases, that will be added to your subscription price. As you might imagine there isn't a lot I can do about that.

Will you still make free tutorials?

Yes, absolutely! I believe it's important to help everyone learn, so I will still be publishing as many free tutorials as I can. This won't be affected by Hacking with Swift+.

Here's a sample of what's waiting for you…

Cupcake Corner



Cupcake Corner

This challenge asks you to upgrade the form validation, add a user-facing error, then switch our data model over to be a struct rather than a class. But rather than just leave it there, I’m going to sneak in a little bonus about Swift keypaths – let’s tackle it now…

Swipe actions, Markdown, and focus



Swipe actions, Markdown, and focus

iOS 15 introduced a great many customization points to give us more control over list rows, text rendering, keyboard focus, and more, and these are all covered here.

Continuing SwiftUI



Continuing SwiftUI

Now that we have covered all the changes in Swift concurrency, we can start to look at the changes in SwiftUI, starting with refreshable() and searchable().

Parsing XML the easy way



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.

Creating a FilteringList to filter a list using text input



Creating a FilteringList to filter a list using text input

Many apps show lots of data in a list, and allow users to filter that list by typing in a text view. In this article we’re going to build that in SwiftUI, then pull it out into a reusable component you can apply anywhere.

How do you stay up to date with changes in Swift?



How do you stay up to date with changes in Swift?

This is particularly important in the world of Apple development because all their major operating systems change every year, Swift sees significant changes two or three times a year, and new devices are shipping regularly.

Storing data in iCloud



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.

Speak Up!



Speak Up!

Apple’s Voice Memos app is great, but wouldn’t it be nice to be able to search your recordings? With the Speech framework we can do just that, and with SwiftUI we can add on a simple UI without much work.

What does the @Published property wrapper do?



What does the @Published property wrapper do?

A great answer should introduce property wrappers, then explain what @Published does, give some examples, compare it against @State, then bring in any extra real-world knowledge you can add around nuances or complexities.

Creating chained network requests with Combine



Creating chained network requests with Combine

We already looked at how to fetch decodable data using Combine, and also how to fetch and merge multiple sources of data. In this article we’ll tackle something even more complex: creating chained network requests, where the information retrieved from one request must be used to create multiple other requests.

Remaking the iOS lock screen



Remaking the iOS lock screen

In this article we’re going to look at how easy it is to rebuild the iOS lock screen. Yes, this isn’t hard, but along the way I think you’ll pick up a few cool SwiftUI tricks, including better date formatting, haptic buttons, and more.

Advanced string interpolation, part one



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.

Have you ever filed bugs with Apple? Can you walk me through some?



Have you ever filed bugs with Apple? Can you walk me through some?

This is another one of my favorite questions to ask folks, because it’s a subtle way to gauge a number of things at the same time without sounding aggressive – after all, it’s Apple’s bugs we’re talking about, rather than the interviewee’s!

Finishing ProjectsView



Finishing ProjectsView

At this point our main list view is almost done, but before we’re finished we’re going to add some icons, make landscape mode work better, and even fix a rather nasty deletion bug.

Using maps in SwiftUI



Using maps in SwiftUI

We’re going to look at integrating MapKit into SwiftUI, but first I want you to try integrating your new knowledge of lazy stacks into a real iOS app.

Adding a meteor shower



Adding a meteor shower

Large parts of Apple’s Weather app is about bringing little sparks of joy to an otherwise very serious, fact-driven experience, but none more so than the random little meteors that fly by on starry nights. They move so fast so you might be tempted to skip over them, but I think it’s definitely worth exploring and having some fun with!

Synchronous vs asynchronous



Synchronous vs asynchronous

Now that you’ve had a taste of how async/await code looks, let’s break down what we just saw and examine how asynchronous functions work behind the scenes, and how we can move over to async let with surprising ease.

Creating a RemoteImage to load images from the web



Creating a RemoteImage to load images from the web

Just like UIKit before it, SwiftUI doesn’t come with built-in support for loading remote images, which makes it hard to get data from the internet. In this article I’ll show you how you can build a custom view that can fetch image from the internet, while also showing other images for different states.

What is UserDefaults good for? What is UserDefaults not good for?



What is UserDefaults good for? What is UserDefaults not good for?

UserDefaults is the simplest way of storing user data, which makes it appealing for beginners, but also useful for even experienced developers who need a sensible place to stash away user preferences. However, it has downsides, and it’s important you’re familiar with them if you want to answer this question well.

How does CloudKit differ from Core Data?



How does CloudKit differ from Core Data?

Although Apple has done a great deal of work to bring these two powerhouse frameworks closer together, they still fundamentally work in entirely different ways, and providing a good comparison might take more thought than you expect.
