A key design goal for my Hacktivate app is for users to build real computer skills while solving challenges. I've just added some SQL-based challenges, all running locally – users need to adjust data to a known hash to be able to log in ✨ Pre-order here: apps.apple.com/gb/app/hackt...

Just one month until I launch my newest app on iPhone, iPad, and Mac. It's called Hacktivate, and it teaches real-world computer science skills using cybersecurity challenges. You can pre-order it here: apps.apple.com/gb/app/hackt...

The Hacking with Swift #WWDC25 sale ends today, but the discount links should carry on working for a little longer. Every year folks email me saying they missed it; don't let that be you! www.hackingwithswift.com/offers

Three weeks ago I was flying back from San Francisco after #WWDC25, and decided to use the flight to start a new app. I just submitted an initial version for TestFlight review – it's early and needs a ton of polish, but I'm really excited about it. It's been so much fun to make!

What's new in SwiftUI for iOS 26? I'm glad you asked! www.hackingwithswift.com/articles/278...

Now that you've seen everything from SwiftUI 26, what is still missing? What are the key pain points you hit? #WWDC25

We’ve just been told that Apple is planning to greatly expand the Apple Developer Forums by adding Discussions – a new way for them to reach out to developers through live streams and Q&A. Coming soon! 🎉

Now that Hacking with Swift IRL is done, I have a little HWS swag leftover – if you see me at #WWDC25 come and say hello and grab some! 🙌

And we’re off! #WWDC25

My #WWDC25 is starting off a little differently from usual.

The first round of applause of the day goes to the Caffè Macs folks who are delivering coffee and treats to folks in line for the big day. (Don’t forget to mute #WWDC25 for the next 48 hours if it’s not your thing!)

Some late-night swag bag packing ahead of CommunityKit! #WWDC25

All checked in and ready to go! #WWDC25

These Apple Park T-shirts are 💯 – instabuy for the rainbow!

Good morning, Cupertino! Time to start beating jet lag with sunshine and coffee ☀️#WWDC25

New on YouTube! 10 Years of Swift: A Decade in Review. Swift launched in 2014, but how did it change in its first ten years? I talk about Swift's journey over a decade, along with my own journey with Swift in that same time. youtu.be/-1z4MYsCIIk

With #WWDC25 around the corner, a lot of folks will be upgrading their projects to a newer iOS deployment target. If you're wondering what new SwiftUI APIs that unlocks for you, I just released something that will help 😎 www.hackingwithswift.com/swiftui

Every year I say to myself, "this will be the year I take it easy during WWDC week." Every year I fail, and this year might be the biggest miss so far 🥲

🗳️ It's almost time for @twostraws.bsky.social and me to record the next #SwiftOverCoffee episode and we want YOUR answers to our open ballot: how do you monetize your apps? How do you set prices? Do you prefer subscriptions or inapp purchases, and how do you implement it all? Let us know!

If you're running a #WWDC25 sale for your app / book, open a pull request on the WWDC repository and tell others about it: github.com/twostraws/wwdc

#WWDC25 is almost here, which means it's time for my annual WWDC sale! Save 50% on all my books and bundles – it's the perfect opportunity to learn something new, expand your skills, or complete your collection! www.hackingwithswift.com/offers

In Saturday's Hacking with Swift+ live stream we built a macOS app that talks to the App Store Connect API to read data about apps, customer reviews, and more. I have now made the stream free to watch *and* open-sourced the project – all contributions welcome! Links in reply…

I just put out the latest update to Testing Swift, not only covering changes in Swift 6.1 and 6.2, but also adding six hours of videos – and it's free for everyone who bought the book previously! ✨ www.hackingwithswift.com/store/testin...

Today is Global Accessibility Awareness Day (#GAAD), so here's a new article for today demonstrating an accessibility technique I only learned myself last year – setting heading levels in text! So easy to do, and makes a real quality of life improvement. www.hackingwithswift.com/quick-start/...

At #WWDC25 I'm holding an in-person Hacking with Swift meetup! I'll be delivering a "What's new in iOS 19?" session, showing a sneak peek of my next book, running a quiz with prizes, and giving away lots of swag! Tickets are free, but spaces are limited! lu.ma/4mk22om8
