Back to slide index.

👋🏻 Hi!

First, don't forget to confirm your attendance using the Seats Mobile app!

Second, I'm going to start every lecture with a meditation from the fantastic Sitting Still Like a Frog book, all read by Myla Kabat-Zinn. If you don't want to participate that's completely fine.

Let's start by watching this video from WWDC25: Better together: SwiftUI and RealityKit. As always, Step Into Vision has a good article about this: Lab 063 – First look at Entity Observation. It's a good practice to get familiar with all the example code, labs and articles on Step Into Vision - bookmark it!

See the linked article: Canyon Crosser: Building a volumetric hike-planning app - download Canyon Crosser to your Xcode and let's try it on headset.

Before going into the article and code in detail, let's watch this video from WWDC25: Meet SwiftUI spatial layout.

Now let's review that article in detail, and dive into the code. Who wants to start by coming up to the front? Don't worry, I'll keep rotating people every 5 minutes. Start the countdown! Also, see this article from Step Into Vision: Exploring custom Layouts in SwiftUI to see how the developer pulled code from Canyon Crosser.

Thanks! As always, please review all today's content as homework.
