FAQ

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…

Accessibility

This challenge asks you to make decorative decorations, make the rows in iExpense read more smoothly with VoiceOver, then conduct your own review of Moonshot and fix it up. Let’s tackle it now…

Existentials and type erasure – part 1

17:14

ADVANCED SWIFT

Existentials and type erasure – part 1

Type erasure helps us solve difficult type system problems by purposefully discarding some information. In this article we’ll look at what the underlying problem is and how Swift solves it, and in the second part we’ll continue on to look at how we can build type erasure ourselves.

Posting comments through CloudKit

ULTIMATE PORTFOLIO APP

Posting comments through CloudKit

The last major piece of CloudKit work we’re going to add will let users post comments on shared projects – hopefully encouraging ones! This will combine querying and writing CloudKit data in a single part of our app, and also demonstrate how to write single records rather than several at once.

Removing optionals from your code

31:24

INTERMEDIATE SWIFT

Removing optionals from your code

Optionals are one of Swift’s most powerful features, letting us write code that is guaranteed to be safe as long as we check and unwrap them carefully. However, more often than not I prefer to avoid optionals as often as possible, and in this article I’ll outline some approaches for doing so.

Integrating with Spotlight

34:58

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.

Creating a FilteringList to filter a list using text input

CUSTOM SWIFTUI COMPONENTS

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.

Sorted arrays

15:34

DATA STRUCTURES

Sorted arrays

A sorted array is one that retains a correct sort order no matter how and when you add items. Although this sounds simple enough to implement, in this article you’ll see that it’s actually quite fun to explore because there are a number of interesting challenges we’ll face.

Storing data in iCloud

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.

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.

Adding haptics

ULTIMATE PORTFOLIO APP

Adding haptics

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.

Testing extensions

26:04

ULTIMATE PORTFOLIO APP

Testing extensions

Our project has three extensions that add functionality to Apple’s own code, and we need to treat these carefully – we don’t own them, so their behavior might change at any point in the future. So, in this article we’re going to write tests for the extensions we created, making sure they work correctly every time.

What are the advantages and disadvantages of SwiftUI compared to UIKit?

INTERVIEW QUESTIONS

What are the advantages and disadvantages of SwiftUI compared to UIKit?

This is another example of a question where exclusively picking one over the other makes you look inexperienced – software development is often fuzzy, and acknowledging that complexity is a mark of experience rather than a weakness.

How can an observable object announce changes to SwiftUI?

INTERVIEW QUESTIONS

How can an observable object announce changes to SwiftUI?

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.

ULTIMATE PORTFOLIO APP

Now for the real work…

Everything we’ve done so far has produced a serviceable app, although it does have a few bugs that we’ll address later. But before we address those, I want to change gear and focus on making our existing code better. This is where the real work begins!

High Rollers

High Rollers

This challenge asks you build an app that simulates random dice rolls on behalf the user, adding haptic feedback to bring it to life, and permanent storage for later reference. Let’s tackle it now…

Codable networking with Combine

NETWORKING

Codable networking with Combine

So much of our job is about downloading JSON data, decoding it using Codable, then presenting it – it’s a core skill. But it’s common to see folks rely on huge libraries such as Alamofire, or get mixed up with URLSession. So, in this article we’ll look at how to rewrite common networking code using Combine, then add some generics to make it truly flexible.

ULTIMATE PORTFOLIO APP

Cleaning up CloudKit, part 2

The second part of cleaning up CloudKit involves tackling error handling head on, and along the way I’ll show you a useful trick for making this process easier. I’ve said it before, but it bears repeating that getting error handling right is the key to a great CloudKit app!
