A Swift library that wraps SQLite with type-safe macros for tables, queries, and writes. You define models with @Table, fetch with @FetchAll/@FetchOne property wrappers, and it handles the SQL generation. Includes CloudKit private database sync, migrations via DatabaseMigrator, and integrates cleanly with SwiftUI's @Observable pattern. The reference guide is thorough on avoiding N+1 queries and transaction pitfalls. If you're building an iOS app that needs local persistence with optional cloud sync and you'd rather work with Swift types than raw SQL strings, this gives you a Rails-like ActiveRecord feel without the ORM baggage.
