Overview

CloudKit moves data between your app and iCloud containers: a private database for each person, a public database everyone can read, and shared records for collaboration. People sign in with their Apple Account, so there are no accounts or servers for you to manage.

CKSyncEngine handles the hard parts of syncing, and SwiftData and Core Data can use CloudKit to sync automatically.

Databases

Private, public and shared databases in iCloud.

CKSyncEngine

Sync local data with iCloud, handled for you.

Sharing

Collaborate on records with other iCloud users.

No servers

Authentication, storage and push included.

SaveNote.swift

import CloudKit

let database = CKContainer.default().privateCloudDatabase

let note = CKRecord(recordType: "Note")
note["title"] = "Groceries"
note["body"] = "Coffee, oat milk, bread"

let saved = try await database.save(note)
print("Saved", saved.recordID.recordName)
