The latest project I’ve been working on is the design of Liquid Glass, alongside an army of designers and engineers. We're designing it to bend and shape light while feeling like an elastic, flexible material that can dynamically shape shift, to make apps feel fluid and organic.

The new project I designed arrives today - the Dynamic Island. Its goal is to feel like a living, elastic bubble that can fluidly shape shift into different alerts and experiences. This is just the start, but I’m excited to see it begin its life!

A little side project I worked on this year was the design of this new flashlight UI in iOS 18.

I contributed this little shockwave moment to the new AirDrop and NameDrop nearby sharing features in iOS 17. Give it a try!

I did a short WWDC presentation where I share some of the thinking behind the design of the Dynamic Island, as well as a bunch of examples and pointers on how to design for it. Check it out in the second half of this talk: developer.apple.com/videos/play/ww…

Dynamic Island definitely wasn’t a solo effort. The industrial design, hardware, and software teams all worked in concert to design and build it. We worked together in an intensely collaborative process over years to make it happen, the only way to make a idea like this possible.

"The Dynamic Island feels not merely like a shape or dedicated area at the top of the screen, but like a real thing with personality. I have genuine affection for it already." So proud of this feature we worked on getting a really positive response.
