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:
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+.

In this introductory video we start by walking through all the main changes introduced with Swift 5.5, without touching on concurrency – that still leaves a heck of a lot!
Apple’s UserDefaults
system lets us store small amounts of user data for our app, which might sound simple but it’s deceptively powerful. In this article I’ll show you the correct way to create initial preferences, how to share preferences across applications, how to synchronize data with iCloud, and why this is a case where property wrappers probably aren’t a good solution.
UPDATED: 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.
Swift’s optionals are a real power feature of the language, but without direct compiler support they would be quite onerous. Optional chaining is one part of that support, so be prepared to answer exactly what part it plays.
UPDATED: 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 issue in one step – it’s more work than you might think!
This challenge asks you to add create a custom arrow shape, make it animatable, then create a color cycling rectangle with controls for gradient angle. Let’s tackle it now…
This sounds like it ought to be straightforward, but usually there’s an ulterior motive here: are you able to work well as part of a team?
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.
UPDATED: At last it’s time to start writing tests for our project, which means a little bit of setup work backed by writing our first couple of tests – we’ll take this slow initially, but lay down a good foundation for future tests.
When it comes to sorting our data, SwiftData has two approaches: the trivial version that works great in a WWDC video and a handful of small projects, and a more complex version that is much more indicative of the kinds of apps you’ll be building in real life.
It’s time for us to build one of the most eye-catching effects in the weather app: the fantastic bolts of lightning that arc down, fork off randomly, and really add some drama to stormy days. This is going to be good…
This sounds like a trick question because so many people rail against singletons, but the real challenge is actually providing a good answer – places where singletons actually work.
This challenge asks you to disallow certain words, let users start a new game whenever they want, and also track player scores. Let’s tackle it now…
UPDATED: Now that we’ve designed a basic awards UI, we can bring it to life with some Core Data queries to determine which awards have actually been earned.
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!
UPDATED: It is my firm belief that every iOS app should be usable to everyone, and putting in the work to make your app function well no matter who is using it says a lot about the kind of developer you are.
Swift 5.9 introduces a whole batch of major changes to the language. It’s hard to believe this is another minor release, but at this point it’s safe to say that Swift 5.9 is more or less unrecognizable from any Swift 4 release.
Pie charts are a classic way of showing divided data visually, and they represent interesting challenges around sizing and angles. In this article we’ll build a complete pie chart view from scratch using SwiftUI, ensuring it works using animation, and also modify it to support donut-style charts too.
In a previous article we already looked at a great way to download data using Combine, but in this article we’re going to examine the other side of the problem: uploading Codable
data. Apple’s API here is a little gnarly, so I’m going to show you how to wrap it in a neat container using generics and Result
.
This might sound like a trivial property wrappers question testing your factual knowledge, but really it’s an architectural decision: what are the advantages and disadvantages of each, and when do they matter?
