Axiom Core Data

What it does

This skill provides access to and synthesizes information from CharlesWiltgen's axiom-core data repository, specifically focusing on Core Data. It enables the AI agent to provide guidance and context related to using Core Data for persistence in iOS applications, particularly when SwiftData is not suitable or when targeting older iOS versions. The skill includes details about choosing between Core Data and SwiftData, setting up a Core Data stack, and integrating with CloudKit.

When to use it

• When needing features that SwiftData doesn't support.
• When developing for iOS 16 or earlier (as SwiftData is only available on iOS 17+).
• For existing applications already using Core Data.
• To understand the considerations when choosing between Core Data and SwiftData persistence frameworks.
• When needing to utilize CloudKit database synchronization.

Key capabilities

• Provides guidance on selecting between Core Data and SwiftData for data persistence.
• Offers information about setting up a modern Core Data stack (iOS 10+).
• Explains how to integrate Core Data with CloudKit for syncing data.
• Highlights common pitfalls ("Red Flags") in Core Data usage, such as thread confinement violations or skipping migration testing.
• Includes code snippets demonstrating CoreDataStack and CloudKitStack setup.

Example prompts

• "What are the advantages of using Core Data over SwiftData?"
• "How do I set up a Core Data stack on iOS 10+?"
• "Can you explain how to integrate Core Data with CloudKit?"
• “What are some common mistakes to avoid when working with Core Data?”

Tips & gotchas

• This skill focuses specifically on Core Data and does not cover other persistence frameworks.
• Be aware of the "Red Flags" mentioned in the source content, as they indicate potential issues that can lead to crashes or data corruption.
• The provided code snippets are examples and may require adaptation for your specific project.
