SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the complexity of implementing SwiftData by providing expert-verified patterns, preventing common runtime crashes, and ensuring adherence to modern Swift concurrency and iOS API requirements.

Core Features & Use Cases

Correctness Validation: Checks code against known SwiftData pitfalls like predicate limitations, actor boundary violations, and incorrect relationship definitions.
Modern Pattern Guidance: Provides best practices for CloudKit integration, database indexing, and model subclassing for iOS 26+.
Use Case: When refactoring a data layer, use this Skill to verify that your predicates are safe for runtime and that your model relationships are correctly defined to avoid circular references or orphaned data.

Quick Start

Use the guide-swiftdata skill to review my current model definitions and check for potential predicate crashes.

FAQPage Schema

How do I define SwiftData model relationships without creating circular references?▼

Define SwiftData model relationships by verifying schema constraints and relationship rules to correctly configure models and avoid circular references or orphaned data.

Does SwiftData work with CloudKit integration for iOS 26+?▼

SwiftData works with CloudKit integration for iOS 26+ by applying modern pattern guidance to sync schema constraints and enforce safe query practices across concurrent boundaries.

What are the common SwiftData concurrency violations and how do I fix them?▼

Common SwiftData concurrency violations include actor boundary breaches, which you fix by enforcing modern Swift concurrency patterns and validating safe query practices during model implementation.

How do I optimize SwiftData database operations for high performance?▼

Optimize SwiftData database operations by identifying indexing opportunities within your schema constraints and enforcing safe query practices to prevent common runtime failures.
