“A Summary of the WWDC26 Group Lab”

The iPhone app just crashed when I tried to sign up for a lab, but I had success doing the signup from the developer web page.

Hi @_lrmathias RealityKit supports the just embed a 3D scene in my app use case. No ARKit required. Start here: the SceneKit to RealityKit migration guide Bringing your SceneKit projects to RealityKit. Side-by-side mapping of SCNScene, SCNNode, SCNCamera, SCNLight, materials, and animations. WWDC25: Bring your SceneKit project to RealityKit. Companion session to the article above. The single most relevant resource for your exact question. Other on-point WWDC sessions WWDC26: Explore advances in RealityKit. WWDC25: What's new in RealityKit. WWDC25: Better together: SwiftUI and RealityKit. Composing 3D scenes inside a SwiftUI app. WWDC24: Discover RealityKit APIs for iOS, macOS, and visionOS. Cross-platform, covers lights, shadows, hover effects. Authoring scenes with Reality Composer Pro Reality Composer Pro lets you build scenes (entities, lights, materials, cameras) visually and load them into your app with Entity(named:). The AR branding is misleading; the output works in any RealityKit context. WWDC26

If you require the answers to the labs, they are in the Teacher's Guide materials available from here https://developer.apple.com/go/?id=app-dev-swift-teacher

It is not going to be sandboxed but rather notarized, so I'm using hardened runtime. Just FYI, I recommend that you use enable the hardened runtime in all your code. While the only place it’s required right now is for notarisation, it’s a good security practice in all situations. My application bundle has now the following structure: That’s a really helpful summary. Thanks! I presume that your login item is actually a Service Management login item, that is, you install it using SMLoginItemSetEnabled. If so, standard practice is to prefix your XPC service name with your Team ID. That will be accessible to your app and your app extensions. If any of the client code is sandboxed, sign it with an app group entitlement that’s a prefix of the XPC service name. For example, if your service name is SKMME9E2Y8.com.example.test703702.service, add an app group ``SKMME9E2Y8.com.example.test703702`.

SwiftData + CloudKit integration doesn't natively support CloudKit sharing today, as discussed in this thread. WWDC26 doesn't have any announcement in this regard. To be clear, you do be able to use Swift the language + Core Data (NSPersistentCloudKitContainer) to implement the sharing feature, as demonstrated in this sample. It's also possible that you implement the sharing feature with your own code by using CloudKit directly, though that will be quite involved. Best, —— Ziqiao Chen  Worldwide Developer Relations.

Thanks for your detailed anwswer. It's claried all the issues for me.Also, I was having a problem with OpenGL ES shader code that converted Display P3 colors to/from the Lab and IPT color spaces. In particular, my results did not match the ColorSync Utility when converting Display P3 to/from Lab. Your mention of D50 caused me to use that reference rather than D65 and now my results match. Switching to D50 also corrected the IPT results.Thanks again!
