Acorn was in Apple's WWDC 2025 keynote! How f'n rad is that?

So a little before WWDC I got a chance to fly down to Cupertino in the dead of night, to secretly adopt Acorn's UI to use the new look and feel of Apple's forthcoming Liquid Glass. NDAs were signed and I can't say much—other than it was super quick to adopt for Acorn's main canvas window. Acorn is a mostly Objective-C app¹ with a codebase that's effectively 20 years old now, so that speaks to how relatively smooth this transition should be.

I was super stoked to be able to do it, and though I'm sure there will be the usual bumps along the way (especially for iOS devs), it's great to have a new UI playground to run around in.

You can watch Acorn's 15 seconds on the big screen with this timestamped YouTube link: Apple's WWDC 2025.
