What problem does it solve?

CloudKit-based apps require robust patterns for storing data in iCloud, syncing across devices, and securely sharing records with other users. This Skill provides guidance, examples, and best practices to implement cloud-backed data experiences using CloudKit.

Core Features & Use Cases

• CKContainer, CKDatabase, and CKRecord management: create, fetch, update, and delete records across private, public, and shared databases.
• Subscriptions and notifications: build real-time updates with CKQuerySubscription and CKDatabaseSubscription.
• Sharing workflows: set up CKShare, manage permissions, and use UICloudSharingController to present sharing UIs.
• Use cases: multi-device note apps, shared document collaboration, and data syncing across user devices.

Quick Start

• Create a record in the private database, subscribe to changes, and present a share UI for the record to enable collaboration.
