Is this skill compatible with Swift 6?

Yes, it is specifically designed for Swift 6 strict concurrency and requires iOS 17 or newer.

Can I use this for single-table inheritance?

Yes, it provides patterns for using @CasePathable enums to model polymorphic data within a single table, offering a value-type alternative to traditional class inheritance.

How does @Fetch help with SwiftUI performance?

The @Fetch wrapper allows you to combine multiple query results into a single database read transaction, reducing round trips and ensuring data consistency across your UI.

How does this differ from the core axiom-sqlitedata skill?

The core skill covers CRUD and basic setup, while this reference focuses on advanced schema composition, inheritance patterns, and complex query optimization.

What is @Selection used for in this context?

@Selection allows you to group related database columns into reusable Swift structs, which are then flattened into the SQL schema for better organization.

Mobile Development

Implements advanced SQLiteData patterns for modern xOS development including complex queries and schema composition.

Acerca de

The axiom-sqlitedata-ref skill provides a deep-dive reference for mastering SQLiteData, a powerful framework for xOS development. It empowers developers to implement sophisticated patterns such as column grouping with @Selection, type-safe single-table inheritance using enums, and complex query composition. This skill is essential for building data-heavy iOS applications that require efficient multi-value database requests, custom aggregates, and clean, reusable query logic while maintaining Swift 6 strict concurrency compliance.

Características Principales

Type-safe single-table inheritance modeling with @CasePathable enums.
233 GitHub stars
Schema composition using @Selection column groups for reusable data structures.
Reusable query scopes and composable logic for cleaner database layers.
Atomic multi-value database requests via the @Fetch property wrapper.
Advanced string functions and recursive CTE pattern implementation.

Casos de Uso

Modeling complex polymorphic data structures without the overhead of class inheritance.
Optimizing SwiftUI view performance by bundling multiple queries into atomic transactions.
Standardizing database access patterns across large-scale iOS and iPadOS projects.
