Swift Core Data

What it does

This skill provides access to Core Data, Apple’s framework for managing the model layer of applications. It allows AI agents to interact with persistent data stores within Swift applications, enabling features like saving user preferences, storing application state, and handling complex data relationships. The agent can query, modify, and create data objects using Core Data's API.

When to use it

• Saving User Preferences: An agent needs to persistently store a user’s preferred theme (light/dark) within a Swift iOS app.
• Managing Application State: An agent is tasked with restoring the state of a game after an application restart, including player progress and inventory.
• Handling Complex Data Relationships: The agent must create and manage relationships between different data entities in a social media application (e.g., users, posts, comments).
• Data Migration: An agent needs to update a Core Data model schema and migrate existing data to the new format.

Key capabilities

• Querying persistent store data
• Creating new managed objects
• Modifying existing managed objects
• Deleting managed objects
• Managing relationships between entities

Example prompts

• "Create a new user with name 'Alice' and email '[email protected]'."
• "Fetch all posts created by user 'Bob'."
• "Delete the comment with ID 123."
• "Update the theme preference to dark mode."

Tips & gotchas

• Requires a working Swift project utilizing Core Data. The agent will need access to the managed object model and persistent store coordinator.
