Why purgeObjectsAndRecordsInZone(with:in:completion:) doesn’t work?

I want to clear all the data in the zone, but I can't delete it. Below is my code, no logs are printed when running.

static func clearData() {
        let coordinator = shared.container.persistentStoreCoordinator
        
        let fm = FileManager.default
        for d in shared.container.persistentStoreDescriptions {
            guard let url = d.url else { continue }
            do {
                if fm.fileExists(atPath: url.path()) {
                    try coordinator.destroyPersistentStore(at: url, type: .sqlite)
                }
            } catch {
                logger.debug("Failed to delete db file, \(error)")
            }
        }
        
        for description in shared.container.persistentStoreDescriptions {
            guard let originalStoreURL = description.url else { continue }
            let walFileURL = originalStoreURL.deletingPathExtension().appendingPathExtension("sqlite-wal")
            let shmFileURL = originalStoreURL.deletingPathExtension().appendingPathExtension("sqlite-shm")
            
            for url in [originalStoreURL, walFileURL, shmFileURL] {
                do {
                    if fm.fileExists(atPath: url.path()) {
                        try fm.removeItem(at: url)
                    }
                } catch {
                    logger.debug("Failed to delete db file, \(error)")
                }
            }
        }
        
        let container = CKContainer(identifier:  appContainerID)
        container.privateCloudDatabase.fetchAllRecordZones { zones, error in
            if let error = error {
                print("Error fetching zones: ")
            } else if let zone = zones?.first, zone.zoneID.zoneName == "_defaultZone" {
                PersistenceController.shared.container.purgeObjectsAndRecordsInZone(with: zone.zoneID, in: nil) { ckShare, error in
                    if let error = error {
                        print("Error purge zones: \(error)")
                    }
                    if ckShare == nil {
                        print("ckShare is nil")
                    }
                }
            }
        }
    }
