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+.

Checkpoint 4 of Swift for Complete Beginners asks you to find the integer square root an input number within a certain range, or throw errors if you can’t do it. Let’s solve that now…
At this point we’ve looked at writing code using async
/await
, using continuations to bridge old code, then optionally using async let
as well. Here we’re going to expand our concurrency knowledge to include tasks and task groups, which provide much more control over our work.
This challenge asks you to add three different animations to the Guess the Flag game from project 2: spinning, fading, and one of your choosing. Let’s tackle it now…
UPDATED: Our app relies extensively on user data, so if there’s one part of it that absolutely must be bullet proof it’s our Core Data stack. In this article we’ll explore writing tests for our data, including tags, issues, and awards.
We’re going to pull apart then rebuild the user interface from the Weather app that shipped with iOS 15 onwards. The app itself is remarkably big, but we’re going to cherry pick all the interesting bits – starting with clouds…
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
.
UPDATED: Although our SwiftUI layouts conform to the View protocol, if you were to try to think about them in MVC terms I’d say they were more like controllers. And like controllers from UIKit, we need to put in some work to keep SwiftUI views lean – let’s look at this now…
UPDATED: Even after writing stacks of unit tests, chances are your test coverage is still only around 50%. Those units tests are really important, but if you really want great test coverage you need to add some UI tests and that’s exactly what we’re going to work on here.
In this article we’re going to build another simple SwiftUI project to continue the Simple SwiftUI series. This time our goal is to build a news reader built through fetching a remote API.
UPDATED: Everything we’ve done so far has produced a serviceable app, although in the future we’ll add a lot more functionality and cross-platform support. But before we get near to those, I want to change gear and focus on making our existing code better. This is where the real work begins!
This challenge asks you to let users switch map styles, show alerts for authentication errors, and create a view model for EditView
. Let’s tackle it now…
One of the big advantages to tasks is that we can pause them, or cancel them outright if their work is longer needed. Even better, for bigger problems we can create whole groups of tasks to accomplish work together.
Now we need to turn our eyes to the first significant piece of work porting to macOS: adjusting the Open and Closed tabs so they look and work better on macOS. This means adding some Mac-only modifiers and views, but it gives us a big step forward as you’ll see.
This is crying out for an example, so once you get the basic answer out of the way back it up with some actual code example where final
is the right choice.
In this part we’re going to build an app to explore SF Symbols, all built using the massive new updates to UICollectionView
that let it act like a table view.
UPDATED: In this article I’m going to walk you through adding haptics to your app, to make it feel a little more alive in the user’s hand.
Boxing allows us to wrap up a struct in a class, to make it easy to share in several places. I’ve touched on boxing briefly previously, but here I want to take the concept much further to add useful protocol conformances that really powerful up its usefulness.
In this stream we're going to build a SwiftUI and SwiftData app that monitors how long Xcode takes to build your projects, then uses that to calculate how much time and money you would save by upgrading to a newer Mac.
In this second tutorial on generics, we’re going to explore creating several different generic types, look at extending generics, and look at how we can apply our generics knowledge to create property wrappers.
UPDATED: We have one last easy task before we look at something trickier, which is to organize the Xcode project itself. Here I’m going to show you two different approaches so you can contrast them yourself, then explain which I prefer and why.
