[iOS15] Fruta Doesn't Launch With Populated State
Asking with the WWDC-10220 tag because Fruta is the sample code for this presentation. When launching Fruta on a landscape iPad Pro 11", the "State" of the application is completely empty until the user taps the back button. After tapping back everything appears to pop into place. Is this expected behavior in SwiftUI when using split screens? NavigationLinks are finicky and I'm expecting the programmatic setting of the primary column "selection" to be resolved on launch, not when the user taps back.

Create a World Anchor from a Spatial Tap Gesture?
World Anchor from SpatialTapGesture ?? At 19:56 in the video, it's mentioned that we can use a SpatialTapGesture to "identify a position in the world" to make a world anchor. Which API calls are utilized to make this happen? World anchors are created with 4x4 matrices, and a SpatialTapGestures doesn't seem to generate one of those. Any ideas?

Retrieve AnchorEntity Location relative to Scene?
I want to place a ModelEntity at an AnchorEntity's location, but not as a child of the AnchorEntity. ( I want to be able to raycast to it, and have collisions work.) I've placed an AnchorEntity in my scene like so: AnchorEntity(.plane(.vertical, classification: .wall, minimumBounds: [2.0, 2.0]), trackingMode: .continuous) In my RealityView update closure, I print out this entity's position relative to "nil" like so: wallAnchor.position(relativeTo: nil) Unfortunately, this position doesn't make sense. It's very close to zero, even though it appears several meters away. I believe this is because AnchorEntities have their own self contained coordinate spaces that are independent from the scene's coordinate space, and it is reporting its position relative to its own coordinate space. How can I bridge the gap between these two? WorldAnchor has an originFromAnchorTransform property that helps with this, but I'm not seeing something similar for AnchorEntity. Thank you
