Core Features & Use Cases

  • Database Management: Supports SwiftData, Core Data, GRDB, and SQLiteData, including advanced querying and schema migrations.
  • Cloud Synchronization: Facilitates CloudKit and iCloud Drive integration for seamless data syncing.
  • Serialization & Storage: Handles Codable issues and provides strategies for file storage and management.
  • Use Case: When encountering issues with CloudKit sync, this skill helps diagnose and resolve the specific error by routing to the appropriate diagnostic skill.

Quick Start

Use the axiom-ios-data skill to help with SwiftData schema migration.

Frequently Asked Questions about axiom-ios-data

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I handle SwiftData schema migration safely without losing data?▼

SwiftData schema migration requires careful routing to appropriate database management tools to prevent data loss. This ensures safe migration by applying correct patterns for querying and schema updates during the transition process.

What is the best way to diagnose CloudKit sync errors on iOS?▼

Diagnosing CloudKit sync errors involves routing the specific synchronization failure to appropriate diagnostic skills. This resolves common iCloud integration issues by identifying the root cause and applying correct data handling strategies.

Does this approach support both Core Data and GRDB for local database operations?▼

Core Data and GRDB are both supported for local database operations alongside SwiftData and SQLiteData. This centralized routing mechanism ensures developers use the most appropriate tool for advanced querying and schema management.

How do I resolve Codable serialization issues when saving iOS app data to file storage?▼

Resolving Codable serialization issues involves applying proper encoding strategies for file storage management. This ensures data persistence by handling serialization errors and providing appropriate storage strategies for iOS applications.

When do I need to use CloudKit synchronization versus local file storage strategies?▼

CloudKit synchronization is needed for seamless iCloud data syncing across devices, while local file storage suits single-device persistence. This centralized routing evaluates requirements to recommend the most appropriate storage mechanism.
