what is Cloudkit

CloudKit is a framework provided by Apple that allows developers to store and sync data across users' devices using iCloud. It is particularly useful for ensuring that data remains consistent and up-to-date across multiple devices. Here are some key points about CloudKit from the WWDC sessions:

1. Syncing Data Across Devices:

   • CloudKit helps in syncing data so that users can continue their progress on different devices. For example, in gaming, it allows game save data to be synced across devices, ensuring that progress is not lost when switching from one device to another (Port advanced games to Apple platforms).

2. Integration with TipKit:

   • CloudKit can be used to sync the display states for tips in an app, ensuring that a user does not need to dismiss the same tip on multiple devices. This improves the user experience by keeping the tips' statuses and rules consistent across devices (Customize feature discovery with TipKit).

3. CloudKit Console:

   • The CloudKit Console is a tool that allows developers to inspect data, manage database schemas, and monitor database activity in their CloudKit containers. It provides features like developer notifications, telemetry tools, and logging to help developers understand and optimize their app's usage of CloudKit (Use CloudKit Console to monitor and optimize database activity).

4. Custom Alerts and Notifications:

   • Developers can create custom alerts based on telemetry data from their CloudKit containers. These alerts can notify developers of key events, helping them to recognize and resolve issues quickly (Use CloudKit Console to monitor and optimize database activity).
