GRDB.swift is a toolkit for SQLite databases with a focus on application development.
The library addresses the need to persist application data in SQLite while handling common database tasks without requiring developers to write raw SQL when they prefer not to. It provides SQL generation that lets you enhance application models with persistence and fetching methods, database observation to receive notifications when values change, robust concurrency support for multi-threaded applications including WAL databases, and schema migration tools. Developers can work at the level of abstraction they prefer, from generated SQL to raw SQL queries when needed.
The tool suits iOS, macOS, tvOS, and watchOS applications that need local data persistence. It works well for teams comfortable with SQLite who want to leverage their SQL skills while also having higher-level abstractions available. The library is particularly valuable when you need database observation capabilities or must handle concurrent reads and writes efficiently. It is installable via the Swift Package Manager.
The project maintains active engagement with its community through multiple channels including discussion forums and issue tracking. Development activity shows consistent attention to compatibility with current Swift tooling and platform requirements. The project has a long history of serving application developers and continues to evolve its capabilities.
