The only problem with the workshop day at @iOSConf is that we can only choose one! I want to see them all! 🤩
ALT Screenshot of the workshop schedule for Do iOS. The first workshop is "intro to app intents" by Daniel Steinberg, the second is "Using instruments to write more performant SwiftUI code" by Donny Wals, and the third is "Building connected devices with embedded swift" by Joannis Orlandos

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…

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.

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.

Working title. But it’s an organized brain dump on organizing a conference.
Interested? Should I publish this? How much would you pay for a copy?

I’m leaving @getstream_io for a role at @dawntechNL. I had a great time at Stream. (Let me know if you need a new contact Stream side if I was your point of contact.)
I go back to my roots of being an iOS developer. But... I'll also be bringing something new to @dawntechNL . :)
