CloudKit is an integrated macOS, iOS, iPadOS, watchOS, and tvOS API that functions as a backend as a service (BaaS).[1] CloudKit is the framework that powers iCloud on those operating systems and on the web.[2]


Application developers can utilize CloudKit for integrated access to Apple's iCloud servers into iOS and macOS applications. The framework provides authentication, a private database, a public database and structured asset storage services allowing developers to focus on client-side development.[2] It is the foundation for both iCloud Storage and iCloud Photo Library.[3]

CloudKit also offers several APIs to access the iCloud Storage, where a user can store data and files so that they can be easily accessible from other devices.[4]


Developers claim that this framework "replaces back-end web services like old-school databases, file storage and user authentication systems."[5]
