Is there any way to render a RealityView to an Image/UIImage like we used to be able to do using SCNView.snapshot() ? ImageRenderer doesn't work because it renders a SwiftUI view hierarchy, and I need the currently presented RealityView with camera background and 3D scene content the way the user sees it I tried UIHostingController and UIGraphicsImageRenderer like extension View { func snapshot() -> UIImage { let controller = UIHostingController(rootView: self) let view = controller.view let targetSize = controller.view.intrinsicContentSize view?.bounds = CGRect(origin: .zero, size: targetSize) view?.backgroundColor = .clear let renderer = UIGraphicsImageRenderer(size: targetSize) return renderer.image { _ in view?.drawHierarchy(in: view!.bounds, afterScreenUpdates: true) } } } but that leads to the app freezing and sending an infinite loop of [CAMetalLayer nextDrawable] returning nil because allocation failed. Same thing happens when I try return renderer.image { ctx in view.layer.render(in: ctx.cgContext) } Now that SceneKit is deprecated, I didn't want to start a new app using deprecated APIs.

In courses like Compose interactive 3D content in Reality Composer Pro Realitykit Engineers recommended working with Reality Composer Pro to create RealityKit packages to embed in our Realitykit Xcode projects. And, comparing the workflow to Unity/Unreal, I can see the reasoning since it is nice to prepare scenes/materials/assets visually. Now when we also want to run a Xcode Cloud CI/CD pipeline this seems to come into conflict: When adding a basic *.usdz to the RealityKitContent.rkassets folder, every build we run on Xcode cloud fails with: Compile Reality Asset RealityKitContent.rkassets ❌realitytool requires Metal for this operation and it is not available in this build environment I have also found this related forum post here but it was specifically about compiling a *.skybox.

So, our app imports CoreML and loads the CoreML models when starting up. Locally all tests succeed consistently. Running Tests on Xcode Cloud, they all fail with (UI and Unit Tests) App (6846) encountered an error (Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying Error: Test crashed with signal ill before establishing connection.)) the test instance is busy for 35min and then just aborts, with all tests failing. This sounds to me like the simulator is maybe showing some exception or is stuck? Or is it possible that xcode server runs in a special environment that gets stuck on loading CoreML models?

Is there any standard way of efficiently showing a MTLTexture on a RealityKit Entity? I can't find anything proper on how to , for example, generate a LowLevelTexture out of a MTLTexture. Closest match was this two year old thread. In the old SceneKit app, we would just do guard let material = someNode.geometry?.materials.first else { return } material.diffuse.contents = mtlTexture Our flow is as follows (for visualizing the currently detected object): Camera-Stream -> CoreML Segmentation -> Send the relevant part of the MLShapedArray-Tensor to a MTLComputeShader that returns a MTLTexture -> Show the resulting texture on a 3D object to the user

So experimenting with the new SpeechTranscriber, if I do: let transcriber = SpeechTranscriber( locale: locale, transcriptionOptions: [], reportingOptions: [.volatileResults], attributeOptions: [.audioTimeRange] ) only the final result has audio time ranges, not the volatile results. Is this a performance consideration? If there is no performance problem, it would be nice to have the option to also get speech time ranges for volatile responses. I'm not presenting the volatile text at all in the UI, I was just trying to keep statistics about the non-speech and the speech noise level, this way I can determine when the noise level falls under the noisefloor for a while. The goal here was to finalize the recording automatically, when the noise level indicate that the user has finished speaking.

I tried animating the scrollTo() like so, as described in the docs. - https://developer.apple.com/documentation/swiftui/scrollviewreader swift withAnimation { scrollProxy.scrollTo(index, anchor: .center) } the result is the same as if I do swift withAnimation(Animation.easeIn(duration: 20)) {     scrollProxy.scrollTo(progress.currentIndex, anchor: .center) } I tried this using the example from the ScrollViewReader docs. With the result that up and down scrolling has exactly the same animation. struct ScrollingView: View {     @Namespace var topID     @Namespace var bottomID     var body: some View {         ScrollViewReader { proxy in             ScrollView {                 Button("Scroll to Bottom") {                     withAnimation {                         proxy.scrollTo(bottomID)                     }                 }                 .id(topID)                 VStack(spacing: 0) {                     ForEach(0..100) { i in                         color(fraction: Double(i) / 100)                             .frame(height: 32)                     }                 }                 Button("Top") {                     withAnimation(Animation.linear(duration: 20)) {                         proxy.scrollTo(topID)                     }                 }                 .id(bottomID)             }         }     }     func color(fraction: Double) - Color {         Color(red: fraction, green: 1 - fraction, blue: 0.5)     } } struct ScrollingView_Previews: PreviewProvider {     static var previews: some View {         ScrollingView()     } }
