An encapsulation of content associated with an app, including content that is accessible to all users and content that is available only to a specific user.

A container object manages all explicit and implicit attempts to access the contents of the container.

Every app has a default container object that manages its own native content. If you develop a suite of apps, you can also access any container objects for which you have the appropriate entitlements. Each new container distinguishes between publicly available data and data that is private to the current user. Private data is always stored in the appropriate container directory in the user’s iCloud account.



Constant Value Description
CKApplicationPermissionStatusCouldNotComplete 1 One of the constants indicating whether the app has been granted a specific permission. An error occurred during the getting or setting of the app permission. Consult the provided NSErrorMBS object for more information.
CKApplicationPermissionStatusDenied 2 One of the constants indicating whether the app has been granted a specific permission. The user denied access to the permission.
CKApplicationPermissionStatusGranted 3 One of the constants indicating whether the app has been granted a specific permission. The user granted access to the permission.
CKApplicationPermissionStatusInitialState 0 One of the constants indicating whether the app has been granted a specific permission. The user has not yet decided whether to grant this permission. Use the requestApplicationPermission method to ask the user to grant the permission.
CKApplicationPermissionUserDiscoverability 1 The current user is discoverable (through the user’s email address) to other users of the app.


Constant Value Description
CKAccountStatusAvailable 1 The user’s iCloud account is available and may be used by this app.
CKAccountStatusCouldNotDetermine 0 An error occurred during an attempt to retrieve the account status. Consult the provided NSError object for more information.
CKAccountStatusNoAccount 3 The user’s iCloud account is not available because no account information has been provided for this device.
CKAccountStatusRestricted 2 The user’s iCloud account is not available. Access was denied due to Parental Controls or Mobile Device Management restrictions.


Constant Value Description
ErrorAlreadyShared 30 A record/share cannot be saved, doing so would cause a hierarchy of records to exist in multiple shares.
ErrorAssetFileModified 17 Asset file content was modified while being saved.
ErrorAssetFileNotFound 16 Asset file was not found.
ErrorBadContainer 5 Un-provisioned or unauthorized container. Try provisioning the container before retrying the operation.
ErrorBadDatabase 24 Operation could not be completed on the given database. Likely caused by attempting to modify zones in the public database.
ErrorBatchRequestFailed 22 One of the items in this batch operation failed in a zone with atomic updates, so the entire batch was rejected.
ErrorChangeTokenExpired 21 The previousServerChangeToken value is too old and the client must re-sync from scratch.
ErrorConstraintViolation 19 The server rejected the request because there was a conflict with a unique field.
ErrorIncompatibleVersion 18 App version is less than the minimum allowed version.
ErrorInternalError 1 CloudKit.framework encountered an error. This is a non-recoverable error.
ErrorInvalidArguments 12 Bad client request (bad record graph, malformed predicate)

ErrorPartialFailure 2 Some items failed, but the operation succeeded overall. Check CKPartialErrorsByItemIDKey in the userInfo dictionary for more details.
ErrorParticipantMayNeedVerification 33 Share Metadata cannot be determined, because the user is not a member of the share. There are invited participants on the share with email addresses or phone numbers not associated with any iCloud account. The user may be able to join the share if they can associate one of those email addresses or phone numbers with their iCloud account via the system Share Accept UI. Call UIApplication's openURL on this share URL to have the user attempt to verify their information.
