It's time to review day four.

We checked in with Raj on how you can organize your iPad interface with SwiftUI. Better support for state restoration, deep linking, and even richer programmatic control. Cool. Then Sara showed us how to bring the power of SwiftUI to your UIKit apps.

Later on, Brett took us through the latest updates for Vision.
Here we compute optical flow for a short clip of this dog fetching a water bottle on a beach.
And we discovered how to create compelling SharePlay experiences.

We also got a lesson in language from Apple's interface writers.
Writing for interfaces begins with curiosity for who's on the other side of the screen.
