To sync your SwiftData app to the public CloudKit database, you can follow these steps:

  1. Enable CloudKit in Your App:

    • Add iCloud to the signing and capabilities of your Xcode project.
    • Turn on CloudKit under iCloud services and create a new container for syncing your data.

  2. Configure Your SwiftData Models:

    • Import the SwiftData framework and decorate each model with the @Model macro.
    • Use the modelContainer modifier on the WindowGroup to inform the view hierarchy about your models.

  3. Set Up CloudKit Syncing:

    • Update your data store configuration to include the CloudKit container option and pass in your new container's ID.
    • Implement the necessary logic to handle syncing, such as resolving merge conflicts between local and cloud data.

  4. Monitor and Optimize with CloudKit Console:

    • Use the CloudKit Console to manage your schema and work with data stored in CloudKit.
    • Set up notifications to be alerted about key events and changes in your CloudKit containers.

For more detailed guidance, you can refer to the following sessions from WWDC 2024:

These sessions provide comprehensive information on setting up and managing CloudKit syncing in your SwiftData app.
