SWIFT EVOLUTION

An overview of last week's Swift Proposal state changes. Check them out when they're in review, as it's your opportunity to influence the direction of Swift's future.

WHAT I'M WORKING ON

​iOSDevUK Accessibility Competition​

Over the past weeks, I've been helping out supporting the iOSDevUK Accessibility Competition. It's now live and you're able to win a free RocketSim license and a free ticket for iOSDevUK 2026. So: join here!​

What's more important: it's a unique opportunity to contribute to the conference's application and train your accessibility skills. It's like learning and helping at the same time.

Lastly, you'll be able to use RocketSim's accessibility features during the competition, as each developer who signs up gets to use RocketSim Pro for free during the competition.

That brings me to a nice segue into one of iOSKonf's talks, performed by Daniel Devesa Derksen-Staats. As a complete surprise to me, he demo'd RocketSim's VoiceOver Overlay in detail:

Daniel previously worked at companies like Apple & Spotify, so seeing him recommending RocketSim meant a lot to me.

You'll have till May 21, 2026 11:59 PM CET (GAAD), to join the competition, so don't wait and join now.
