Hey All, I have a Reference (List) property in my CloudKit record type that points to a variety of locations. When I fetch the record with the reference (List), how do I then fetch the locations that the reference (List) is pointing to? Thanks! Here is my `code: func getLocationsWhereVendorIsSelling() {

// Retrieve Profile Record ID

guard let profileRecordID = CloudKitManager.shared.profileRecordID else { return }

CloudKitManager.shared.fetchRecord(with: profileRecordID) { result in

switch result {

        // Get profile record

case .success(let record):

// Location References in profile

let locationReferences = record[MLProfile.kIsSellingAt] as? [CKRecord.Reference]

// Get all locations

let locations = self.locationManager.locations

// Filter locations by the ones that have the reference

let predicate = NSPredicate(format: "%K CONTAINS %@", locationReferences!, locations)

// Add locations to the soldToLocations array

let query = CKQuery(recordType: RecordType.location, predicate: predicate)

CKContainer.default().publicCloudDatabase.perform(query, inZoneWith: nil) {

locationRecords, error in

guard let locationRecords = locationRecords, error == nil else {

print(error!.localizedDescription)

return

}

print(locationRecords)

}

case .failure(_):

print("Error getting all the locations")

}

}`

The CKRecord.Reference class has a recordID (CKRecord.ID) property, which you can use to fetch the actual referenced CKRecord. In your case it looks like you'd be fetching a list, so you could use the fetch(withRecordIDs:) method to fetch all IDs in a single transaction documented here.

Thanks for the response! How do I access the recordIDs? My constant "let locationReferences..." does not have a recordID that I am able to access. I thought about using a for loop to loop through the locationReferences, but that does not seem like the right approach.
