I'm having trouble getting the "Save to Files" option to work with ShareLink. Here's a simple example:
struct Item: Transferable {
public static var transferRepresentation: some TransferRepresentation {
FileRepresentation(exportedContentType: .jpeg) { item in
// Write a jpeg to disk
let url = URL.documentsDirectory.appending(path: "item.jpeg")
let jpegData = UIImage(named: "testImg")!.jpegData(compressionQuality: 1)!
try! jpegData.write(to: url)
return SentTransferredFile(url)
}
}
}
struct ContentView: View {
var body: some View {
ShareLink(item: Item(), preview: SharePreview("Test Item"))
}
}
The ShareSheet presents all of the usual options, but tapping "Save to Files" briefly presents an empty modal before immediately dismissing.
The following errors are logged to the console:
2022-09-12 14:19:57.481592-0700 ExportTest[3468:1374472] [NSExtension] Extension request contains input items but the extension point does not specify a set of allowed payload classes. The extension point's NSExtensionContext subclass must implement `+_allowedItemPayloadClasses`. This must return the set of allowed NSExtensionItem payload classes. In future, this request will fail with an error.

Additionally, this error is logged when the ShareSheet is first presented (before tapping Save to Files):
[ShareSheet] Couldn't load file URL for Collaboration Item Provider:<NSItemProvider: 0x282a1d650> {types = (
"public.jpeg"
)} : (null)
Has anybody had luck getting custom Transferable representations to work with ShareLink?

The various "flood fill" functions from the vImage library (e.g. vImageFloodFill_Planar8 - listed here) are missing from Xcode 14.0.1.
Is there a way to access them?
Ex:
import Accelerate
// --> Cannot find 'vImageFloodFill_Planar8' in scope
let err = vImageFloodFill_Planar8(
&buffer,
nil,
100,
100,
128,
8,
0)
)
