When implementing a QLPreviewingController on iOS, we only get the Spotlight uniqueIdentifier but not the actual CSSearchableItem.
I thought I could use CSSearchQuery with a query like this
"uniqueIdentifier == \"\(identifier)\""
to fetch the CSSearchableItem of the selected item from Spotlight. However, I always receive an error:
<CSSearchQuery:0x2826e51e0 qid=1 flag=0x0000>error:Error Domain=NSCocoaErrorDomain Code=4099 "Couldn’t communicate with a helper application.">
Is it not possible to call Spotlight from a QuickLook Preview extension? Is there another way to retrieve the CSSearchableItem for the item to be previewed?
