The premier iOS developer conference in the Netherlands is back! 🇳🇱📱
Whether you’re deep into advanced SwiftUI architectures, performance tuning, or navigating the latest Apple frameworks, staying ahead requires more than just documentation—it takes community.
That’s why Do iOS is built by developers, for developers.
Join us on November 11–12 at the iconic NEMO Science Museum in Amsterdam for two packed days of:
✨️ Expert talks on cutting-edge iOS engineering
🤝 Incredible networking with fellow engineers, leads, and independents from across Europe
💡 Practical takeaways you can apply directly to your codebase the very next week
Tickets are moving fast, and you won’t want to miss the lineup we’ve put together this year.
👉️ Secure your spot and check out the schedule today: do-ios.com

The only problem with the workshop day at @iOSConf is that we can only choose one! I want to see them all! 🤩

Proud to bring Pol back to the conference where his public speaking journey started.
Hi @polpielladev, so happy to have you speaking again. :)

Scrolling through a few of the 2024 videos of Do iOS. I'm still humbled by the quality of the speakers. :)

"Most satisfying fix of the week: a mysterious moving volume slider bug." Shared my journey refactoring an audio engine and managing background tasks in iOS. Sometimes the best code is the code you don't write. Listen to the full story now. #SwiftDev buzzsprout.com/1414396/episo…
Hey, let's just dump many things in UserDefaults... What could possibly go wrong...

Do iOS conference returns in November 2025!
AppForce1 podcast evolves into a developer work log - sharing real code, real struggles, and real solutions from my day-to-day iOS development. What challenges are you facing that you'd like me to cover?

Meanwhile... Does anyone have a working example of Apple's Push to Talk? It's a fun feature, but docs and samples are very, very, very few.
Lots of emailing and website editing in the evening the last few days. With results. All but 2 speakers are now listed fo Do iOS. :)

Ticket sales are heating up. Getting some reports of trouble with buying a ticket.
Could be just a popup blocker in your browser. But if you are having issues, try the direct Paydro link instead.
It is listed on our site, but here it is as well.

No biggie... Just confirmed on the largest expense of the entire event. Venue, staff and catering. Do iOS is on!
First 3 speakers are on the website. Session order will develop over the next couple weeks. It will be a mix of familiar and new... do-ios.com

Embedded Swift is already running in production, and not just at Apple either!
Do you want to learn a true full stack approach? One that transcends mobile into hardware too?
Join me in November!
If you are itching to get your hands dirty with the new product embedded Swift, I’ve a steal of a deal for you.
Join the workshop by @JoannisOrlandos at Do iOS. Best part. Hardware kit included and part of the package you get to take home at the end of the workshop.
I’ve been quiet the last couple months because I was investeren jobs and took some time off.
Now I am back. Working at @dawntechNL.
