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+.

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!
This challenge asks you to figure out a modifier conundrum, show alerts for authentication errors, and create a view model for EditView
. Let’s tackle it now…
Codable
is the fastest and easiest way to store Swift objects, but what happens when your data types need to evolve to add extra information? In this tutorial I’ll show you the traditional way this is solved, and also a different version that I find significantly easier to use.
UPDATED: Our app was designed to work in English, and although you might not want to change that your should at least be able to change. Let’s fix that now…
Getting observable objects right is one of the keys to having a smooth experience with SwiftUI, but getting them wrong is a sure-fire recipe for massive performance problems no matter what platform you’re writing for.
Apple’s NotificationCenter
class implements the observer pattern from the Gang of Four book on design patterns, allowing any number of objects be notified when a specific event happens. But to answer this question well, you need to go beyond theory and focus on when it’s actually used.
We’ve added quite a bit of iCloud functionality in the last few tutorials, so before we’re done we need to clean up what we have so it’s a solid foundation we can build on. To start with, that means tackling removing data as well as we handling adding data.
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…
In this article we’re going to look at how to rebuild the Tips app using SwiftUI, including how to make scrolling tabs of content, how to get a parallax scrolling effect, and more.
This question comes up a lot, but I’m always wary of it because it places a lot of emphasis on unpaid work out of hours, which particularly affects people who already have extra responsibilities caring for children or elders.
In this part we finish by directly comparing async let
, tasks, and task groups, then move on to the final boss of Swift concurrency: actors.
This is a brilliant question to ask, because it gives the interviewee the scope to pick their own area of expertise and delve into it, and it’s also a brilliant question to answer because you’re in control – you get to direct the conversation!
This challenge asks you add a photo credit to resort images, handle loading and saving of favorite resorts, then add sorting options to the main listing. Let’s tackle it now…
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.
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.
From iOS 17 onwards, we can dynamically adjust any SwiftUI views using Metal shaders. I’m going to show you how to do it, but not just how to apply them – I’m going to show you how to write your own shaders using Metal shading language! In this first article I’ll introduce how shaders work, along with some fundamental data types and a handful of Metal functions.
Checkpoint 9 of Swift for Complete Beginners asks you to write a function to pick a number from an optional array, or return a random number if that’s not possible. Let’s solve that now…
There’s a quote from James Shore that I absolutely love, and I always start with it when introducing this concept to folks: “Dependency injection is a 25-dollar term for a 5-cent concept.”
In this stream we’re going to build something unusual, something powerful, and something fun all at once: it’s a development tool that helps you experiment with one of the powerful new iOS 17 APIs.
This early challenge day asks you to build a converter app that’s able to move between any two similar units, such as kilometers and miles. Let’s solve it now, then we’ll take it further, and then we’ll take it even further…
