Dropping URL itemProvider from app… | Apple Developer Forums

Dropping URL itemProvider from app to desktop creates a copy instead of moving it.

I register a file representation on my dragItem's Itemprovider like the following:

Code Block swift provider.registerFileRepresentation(forTypeIdentifier: itemTuple.uti, fileOptions: .openInPlace, visibility: .all, loadHandler: { (completion: ((URL?, Bool, Error?) -> Void)) -> Progress? in
                let fileCoord = NSFileCoordinator(filePresenter: nil)
                var fileError: NSError?
                let progress = Progress(totalUnitCount: 1)
                progress.completedUnitCount = 1
                fileCoord.coordinate(writingItemAt: url, options: [.forMoving], error: &fileError, byAccessor: { [fileError] fileURL in
                    if let error = fileError {
                        completion(nil, false, error)
                        progress.completedUnitCount = 1
                    }
                    completion(fileURL, true, nil)
                    progress.completedUnitCount = 1
                })
                return progress
            })

Code Block swift
provider.registerFileRepresentation(forTypeIdentifier: itemTuple.uti, fileOptions: .openInPlace, visibility: .all, loadHandler: { (completion: ((URL?, Bool, Error?) -> Void)) -> Progress? in
let fileCoord = NSFileCoordinator(filePresenter: nil)
var fileError: NSError?

let progress = Progress(totalUnitCount: 1)
progress.completedUnitCount = 1

fileCoord.coordinate(writingItemAt: url, options: [.forMoving], error: &fileError, byAccessor: { [fileError] fileURL in

if let error = fileError {
completion(nil, false, error)
progress.completedUnitCount = 1
}
completion(fileURL, true, nil)
progress.completedUnitCount = 1
})

return progress
})

When I drop the thumbnail onto the desktop a breakpoint on
line 14 is called, but finder creates a Copy.

I've created the fileCoordinator with .forMoving.
I've registered the file representation with fileOptions: .openInPlace
I'm also responding with true in

Code Block public func collectionView(_ collectionView: UICollectionView, dragSessionAllowsMoveOperation session: UIDragSession) -> Bool

Code Block
public func collectionView(_ collectionView: UICollectionView, dragSessionAllowsMoveOperation session: UIDragSession) -> Bool

Is there something else I'm missing for finder to consider this a moveable file URL?
