# Responding to Requests to Delete Data

Provide options for users to delete their CloudKit data from your app.

## Overview

Overview If your app stores data in CloudKit on behalf of your users, give them a simple way to delete their data. Identify Containers To be sure that you delete all of a user’s data that your app stores in CloudKit, cross-reference the list of containers your app has access to in Xcode and assemble a list of those containers’ identifiers. Identifying an App’s Containers describes this process. The example below stores containers in an array to use later for enumeration: let containers: [CKContainer] = [     CKContainer.default(),     .init(identifier: "iCloud.com.example.myexampleapp.documents"),     .init(identifier: "iCloud.com.example.myexampleapp.settings") ] Delete Records The example below uses an instance of CKModifyRecordZonesOperation to delete all records in each container’s private database: for container in containers {     container.privateCloudDatabase.fetchAllRecordZones { zones, error in         guard let zones = zones, error == nil else {             print("Error fetching zones.")             return         }                  let zoneIDs = zones.map { $0.zoneID }         let deletionOperation = CKModifyRecordZonesOperation(recordZonesToSave: nil, recordZoneIDsToDelete: zoneIDs)                  deletionOperation.modifyRecordZonesCompletionBlock = { _, deletedZones, error in             guard error == nil else {                 let error = error!                                  print("Error deleting records.", error)                 return             }

print("Records successfully deleted in this zone.")         }                  container.privateCloudDatabase.add(deletionOperation)     } }
