I have some strange behavior in my app. When I set the position to .zero you can see the sphere normally. But when I change it to any number it doesn't matter which and how small. The Sphere isn't visible or in the view.
The RealityView
import SwiftUI
import RealityKit
import RealityKitContent
struct TheSphereOfDoomRV: View {
@StateObject var viewModel: SphereViewModel = SphereViewModel()
let sphere = SphereEntity(radius: 0.25, materials: [SimpleMaterial(color: .red, isMetallic: true)], name: "TheSphere")
var body: some View {
RealityView { content, attachments in
content.add(sphere)
} update: { content, attachments in
sphere.scale = SIMD3<Float>(x: viewModel.scale, y: viewModel.scale, z: viewModel.scale)
} attachments: {
VStack {
Text("The Sphere of Doom is one of the most powerful Objects. You can interact with him in every way you can imagine ").multilineTextAlignment(.center)
Button {
} label: {
Text("Play Video!")
}
}.tag("description")
}.modifier(GestureModifier()).environmentObject(viewModel)
}
}
SphereEntity:
import Foundation
import RealityKit
import RealityKitContent
class SphereEntity: Entity {
private let sphere: ModelEntity
@MainActor
required init() {
sphere = ModelEntity()
super.init()
}
init(radius: Float, materials: [Material], name: String) {
sphere = ModelEntity(mesh: .generateSphere(radius: radius), materials: materials)
sphere.generateCollisionShapes(recursive: false)
sphere.components.set(InputTargetComponent())
sphere.components.set(HoverEffectComponent())
sphere.components.set(CollisionComponent(shapes: [.generateSphere(radius: radius)]))
sphere.name = name
super.init()
self.addChild(sphere)
self.position = .zero // .init(x: Float, y: Float, z: Float) and [Float, Float, Float] doesn't work ...
}
}

I can't find WorldSensingUsageDescription key in the plist. Anyone else with the same problem? I am using Xcode Beta 15.6

Hello,
Yesterday I updated xCode 15.2 Beta to 15.5. Now i tried to run my App but after starting i I recognized that when I open my volumetric window that the USDA scene in my RealityView doesn't file doesn't appear anymore. RealityView will be executed.+
When I use a 3D Model in my volumetric window the USDA appears without any problems.
Here is my code:

struct MyWindow: View {
var body: some View {
RealityView { content in
async let object = ModelEntity(named: "testScene", in: realityKitContentBundle)
print("I exec")
guard let object1 = try? await cloudyWeather else {return }
object1.generateCollisionShapes(recursive: false)
object1.components.set(InputTargetComponent())
object1.location = .init(0,0.5,0)
object1.scale *= 1
content.add(object1)
}.gesture(dragGesture)
}
var dragGesture: some Gesture {
DragGesture()
.targetedToAnyEntity()
.onChanged { value in
print(value.entity.name)
value.entity.position = value.convert(value.location3D, from: .local, to: value.entity.parent!)
}
}

Hello,
Right now I am learning some RealityKit for VisionOS. I do not receive any errors in my code so it seems okay. But I can't drag my object around. Does the SIM supports gestures in general?
