SwiftData predicate safety is verified by checking that queries use supported operations and avoid patterns that compile but crash. Review FetchDescriptor usage and model relationships to ensure runtime stability across iOS targets.

CloudKit constraints for SwiftData models require avoiding unsupported query patterns and relationship configurations. Apply release-specific rules for CloudKit compatibility to prevent sync failures and ensure correct model implementations across iOS versions.

Using FetchDescriptor with supported predicates in Swift Testing involves verifying that SwiftData query expressions follow modern API patterns. Check predicate operations against supported SwiftData functionality to avoid runtime crashes during tests.

SwiftData supports indexing changes introduced in iOS 18, requiring specific query pattern adjustments. Apply iOS 18 indexing considerations when reviewing model code to ensure FetchDescriptor predicates and relationship queries remain correct and performant.

SwiftData class inheritance rules for iOS 26 require following specific guidance when defining model hierarchies. Review model code to ensure inheritance patterns comply with release-specific constraints and avoid correctness pitfalls in relationship configurations.

A SwiftData predicate may compile but crash at runtime if it uses unsupported query operations or incorrect relationship patterns. Review predicate expressions against supported SwiftData APIs and FetchDescriptor rules to identify and fix fragile implementations.
