I have a class with an Entity, on which I added a Spatial Audio component. Furthermore, I have a function, which uses the playAudio() method to start the Spatial Audio. During the first call of the function, everything is fine. If I call the again, the audio volume drops abruptly after a half second. It is very quiet.
Approximately, I have following code:
class VoiceOutputPlayer: NSObject, ObservableObject, AVAudioPlayerDelegate {
private var speechEntity = Entity()
func play() {
Task{
let audioRessource = try await AudioFileResource(contentsOf: urlWave)
self.speechEntity.playAudio(audioRessource)
}
}
func initSpatialAudio() -> Entity {
speechEntity.transform.translation.y = -0.37
speechEntity.transform.translation.z = 0.09
speechEntity.spatialAudio = SpatialAudioComponent(gain: Double.zero)
speechEntity.spatialAudio?.reverbLevel = -2
speechEntity.spatialAudio?.directivity = .beam(focus: 0.9)
speechEntity.orientation = .init(angle: .pi, axis: [0, 1, 0])
speechEntity.spatialAudio?.distanceAttenuation = .rolloff(factor: 1)
return speechEntity
}
}
Have visionOS 2.2 on the Apple Vision Pro and use Xcode 16.1

When I try to upload an app to the AppStore, I receive following feedback:
I had Xcode 16 with visionOS installed.
Because of the feedback, I switched back to Xcode 15.3 with visionOs 1.0.
I archived it again and tried to upload the app again. But I still receive the same feedback.
I also tried https://stackoverflow.com/questions/56518791/app-store-refuses-my-update-after-installing-xcode-11-beta-with-keeping-xcode-10/56623421#56623421, but it seems that there is no such property for visionOS in the info.plist
I do not have any further ideas...
I wanted to try the new Object Tracking. So I captured an object and uploaded it in Create ML in an Object Tracking project. I added my used file and set the viewing angle to "upright". Afterwards, I startet the training. After some time (around 2%), it stops and I receive following error message: "There isn't enough space. at "1921.blob". I tried it multiple times.
Currently, I try to test the ImageTrackingProvider with the Apple Vision Pro. I started with some basic code:
import RealityKit
import ARKit
@MainActor class ARKitViewModel: ObservableObject{
private let session = ARKitSession()
private let imageTracking = ImageTrackingProvider(referenceImages: ReferenceImage.loadReferenceImages(inGroupNamed: "AR"))
func runSession() async {
do{
try await session.run([imageTracking])
}
catch{
print(error)
}
}
func processUpdates() async {
for await _ in imageTracking.anchorUpdates{
print("test")
}
}
}
I only have one picture in the AR folder. I added the size an I have no error messages in the AR folder.
As I am trying to run the application with the vision Pro, I receive following error:
ar_image_tracking_provider_t <0x28398f1e0>: Failed to load reference image <ARReferenceImage: 0x28368f120 name="IMG_1640" physicalSize=(1.350, 2.149)> with error: Failed to add reference image.
It finds the image, but there seems to be a problem with the loading. I tried the jpeg and the png format.
I do not understand why it fails to load the ReferenceImage.
I use Xcode Version 15.3 beta 3
