  Apple ships no CloudKit client library on any language registry for the CloudKit Web Services REST
  surface itself. The first-party distribution is (a) CloudKit JS, served from Apple's own CDN as an
  unversioned script URL, (b) the four CKTool JS packages Apple publishes to npm under the @apple
  scope, and (c) the native CloudKit framework, which ships inside the Apple platform SDKs rather than
  through a package registry. npm searches for "cloudkit" return only third-party wrappers
  (tsl-apple-cloudkit, expo-cloudkit, capacitor-cloudkit) — none are Apple's and none are recorded here.

    Read from the `version:"2.5.7"` string inside the served bundle (HTTP 200, application/javascript,
    173,391 bytes, fetched 2026-09-05). The distribution URL is UNPINNED — the path segment `ck/2` is a
    major version only, so the exact build floats and a consumer cannot tell which release they loaded.
    Apple publishes no release date and no changelog for the file; `published: null` means checked and
    nothing to record, not unchecked.

    CKTool JS main package — the scripted client for the CloudKit Management API used for schema
    import/export, reset and test-data loading. Version and date read from registry.npmjs.org metadata
    on 2026-09-05. Four years without a release is the strongest currency signal on this provider.

  note: >-
    The native CloudKit framework is versioned with iOS/iPadOS/macOS/tvOS/watchOS/visionOS and shipped
    inside the Apple SDKs in Xcode. There is no package registry entry to query, so version/published
    are null by construction rather than unknown.

    Apple publishes nine first-party CloudKit sample repositories under github.com/apple. They are
    example apps, not client libraries, so they are recorded here rather than as packages.
