1Swiftdata ProSwiftData Pro writes, reviews, and improves SwiftData persistence code for iOS/macOS projects targeting Swift 6.2 or later. Developers use it when building or auditing model layers that rely on SwiftData instead of Core Data, including CloudKit-synced apps and projects adopting iOS 18 indexing or iOS 26 class inheritance. The skill loads modular reference files - core rules, predicate safety, CloudKit constraints, indexing, and class inheritance - only as needed for the task at hand. For reviews it organizes findings by file, names the violated rule, and provides before/after code snippets. For write or improve tasks it applies the same rules directly to the code. It enforces explicit delete rules on relationships, safe predicate patterns, correct @Query placement inside SwiftUI views, and modern Swift concurrency throughout.6.5kinstalls
