I have been trying to get this to work since it was announced a few years ago but with no joy. I'm struggling to get Apple's example code to behave itself too. Seems overly complex and buggy. So I set out to create a simplified version myself. I have got the database to sync with CloudKit and I can see my records in the developer dashboard. I'm trying to use container.record(for: object.objectID) to get the CKRecord for it, but this always fails. The next step would be to add the participant.
I try to add the participant based on this code:
Button
{
let record = fetchRecord(for: items[0]) //hack just to use the first record for dev testing
let share = CKShare(rootRecord: record)
let persistenceController = PersistenceController.shared
persistenceController.addParticipant(
emailAddress: "andrew@ambrit.com",
permission: .readWrite,
share: share)
{ share, error in
if let error = error
{
print("Error: \(error.localizedDescription)")
}
else if let share = share
{
print("Share updated successfully: \(share)")
}
}
}
label:
{
Label("Participants", systemImage: "person")
}
and
extension PersistenceController
{
func addParticipant(emailAddress: String, permission: CKShare.ParticipantPermission = .readWrite, share: CKShare,
completionHandler: ((_ share: CKShare?, _ error: Error?) -> Void)?)
{
let container = PersistenceController.shared.container
let lookupInfo = CKUserIdentity.LookupInfo(emailAddress: emailAddress)
let persistentStore = privatePersistentStore //share.persistentStore!
container.fetchParticipants(matching: [lookupInfo], into: persistentStore) { (results, error) in
guard let participants = results, let participant = participants.first, error == nil else
{
completionHandler?(share, error)
return
}
participant.permission = permission
participant.role = .privateUser
share.addParticipant(participant)
container.persistUpdatedShare(share, in: persistentStore)
{ (share, error) in
if let error = error
{
print("\(#function): Failed to persist updated share: \(error)")
}
completionHandler?(share, error)
}
}
}
}
My immediate problem is that when I call fetchRecord it doesn't find anything despite the record being available in the CloudKit dashboard.
func fetchRecord(for object: NSManagedObject) -> CKRecord
{
let container = PersistenceController.shared.container
print ("Fetching record \(object.objectID)")
if let record = container.record(for: object.objectID)
{
print("CKRecord ID: \(record.recordID)")
print("Record Name: \(record.recordID.recordName)")
return record
}
else
{
fatalError("Record not found")
}
}

This code was working fine in Monterey but since upgrading to Ventura it no longer works:
let contactsUTTypes = [UTType.vCard, UTType.contact]
func performDrop(info: DropInfo) -> Bool
{
print (info)
let items = info.itemProviders(for: contactsUTTypes)
print (items)
for item in items
{
item.loadDataRepresentation(forTypeIdentifier: UTType.vCard.identifier, completionHandler: { (data, error) in
if let data = data,
let contact = try? CNContactVCardSerialization.contacts(with: data).first
{
print("Contact: \(contact.givenName)")
}
})
}
return true
}
let items = info.itemProviders(for: uttypes)
always returns zero items
Has this been broken in Ventura or do I need to do this differently now?
I have been waiting for this for many years. Thank you. Is there demo code that accompanies this video?
