I've been using the CloudKitHelper Class that I found here. My app is only on iOS16, so getting the above message is something I'd like to remove. I've looked everywhere and have not found any examples of people dealing with the new method. Given that the CloudKitHelper class is using recursion a simple replacement of operaion.modifyRecordZonesCompletionBlock to operation.modifyRecordZonesResultBlock, provides many more errors.

    public static func modifyRecordZonesOperation(
        database: CKDatabase,
        recordZonesToSave: [CKRecordZone]?,
        recordZoneIDsToDelete: [CKRecordZone.ID]?,
        modifyRecordZonesCompletionBlock: @escaping (([CKRecordZone]?, [CKRecordZone.ID]?, Error?) -> Void)) {
            let logger=Logger(subsystem: "tracker", category: "PersistentCloudKitContainer")
            let operation = CKModifyRecordZonesOperation(
                recordZonesToSave: recordZonesToSave,
                recordZoneIDsToDelete: recordZoneIDsToDelete)
            // swiftlint:disable:next line_length
            operation.modifyRecordZonesCompletionBlock = { (savedRecordZones: [CKRecordZone]?, deletedRecordZoneIDs: [CKRecordZone.ID]?, error: Error?) -> Void in
                if let error = error {
                    if let delay = determineRetry(error: error) {
                        DispatchQueue.global().asyncAfter(deadline: .now() + delay) {
                            CloudKitHelper.modifyRecordZonesOperation(
                                database: database,
                                recordZonesToSave: recordZonesToSave,
                                recordZoneIDsToDelete: recordZoneIDsToDelete,
                                modifyRecordZonesCompletionBlock: modifyRecordZonesCompletionBlock)
                        }
                        logger.log("modifyRecord Error \(error.localizedDescription), trying delayed retry of \(delay)")
                    } else {
                        modifyRecordZonesCompletionBlock(savedRecordZones, deletedRecordZoneIDs, error)
                    }
                } else {
                    modifyRecordZonesCompletionBlock(savedRecordZones, deletedRecordZoneIDs, error)
                }
            }
            database.add(operation)
        }

I would appreciate any pointers at how to address this. Thanks

Is it an error such that it will not compile, or merely a warning?

Generally, "deprecated" means you can still use it, but Apple encourages you to transition away from it because it will be discontinued eventually, possibly years from now.

It is currently a warning, but I'd like to see how to do it correctly going forward. I tried just chaning .modifyRecordZonesCompletionBlock to .modifyRecordZonesResultBlock but the signature is very different. It seems like it will break the recursion approach used by the above code.

Looking at Apple Documents modifyRecordZonesResultBlock while it not very helpful, it say that it use Result type not completion handlers. So it writing the hander return .success or .failure. I am not sure.
