I have the following code in a View that I show via a NavigationStack path.push() statement:
@State private var avatarItem: PhotosPickerItem?
@State private var avatarImage: Image?
var body: some View {
VStack(alignment: .center) {
VStack {
if let avatarImage {
avatarImage
.resizable()
.frame(width: 200, height: 250)
.foregroundColor(.gray)
.padding()
} else {
Image("profile")
.resizable()
.frame(width: 200, height: 200)
.foregroundColor(.gray)
.padding()
}
PhotosPicker(selection: $avatarItem) {
Label("Select a Photo", systemImage: "photo.artframe")
}
.padding()
// process a selected image from the photo library
.onChange(of: avatarItem) { newValue in
Task {
if let imageData = try? await newValue?.loadTransferable(type: Data.self), let image = UIImage(data: imageData) {
avatarImage = Image(uiImage: image)
}
}
} etc...
It works and the selected image is displayed properly, but the console shows the following errors (plural):

This view is a couple of levels into my NavigationStack. I've toyed with moving some of the logic into the main thread, but that has not helped.
The error
2023-08-07 15:58:40.433125-0600 xxxapp[5264:603960] [AXRuntimeCommon] Unknown client: xxxapp
appears when the PhotoPicker is tapped and displayed, the rest when it returns.
I also get a detached view controller error when this view is displayed, is that related? (Haven't figured that one out, yet, early days.)

I'm using Xcode 14.3.1, target of iOS 16.4. The AXRuntime errors only appears on-device, not in the simulator.
I have also tried making this run on the main thread, no change.
TIA!
Apparently this is an iOS bug. Thank you devdchaudhary
