GRDB.swift

What GRDB.swift is

GRDB.swift is a free, open-source Swift toolkit for storing application data in SQLite databases. It gives developers SQL execution, query generation, and fetching and persistence methods for Swift record types. Migration tools help an application change its database schema as new versions are released. Database pools support concurrent access and use SQLite WAL mode unless the database is opened read-only. Database observations can be consumed through Swift concurrency, Combine, or RxSwift. GRDB.swift can encrypt databases with SQLCipher, with installation guidance for Swift Package Manager and CocoaPods. The README documents installation through Swift Package Manager, CocoaPods, or manual project integration. Stated requirements include Swift 6.1+, Xcode 16.3+, and SQLite 3.20.0+, with iOS 13.0+, macOS 10.15+, tvOS 13.0+, and watchOS 7.0+ listed for Apple platforms. Linux support is provided by contributors and is not automatically tested or officially maintained. CocoaPods cannot publish new GRDB versions and lists 6.24.1 as its latest available version; Carthage is unsupported. The MIT license permits use, copying, modification, distribution, sublicensing, and sale when its copyright and permission notice remain included. The project also lists GRDBQuery and GRDBSnapshotTesting companion libraries.

Who it suits

GRDB.swift suits Swift developers who need SQLite persistence, schema migrations, concurrent database access, or observable data in Apple applications. It also fits projects wanting SQLCipher encryption or a permissive MIT-licensed toolkit, provided their platform and toolchain meet the stated requirements.

Limits

GRDB.swift is free. Linux support is not automatically tested or officially maintained, Carthage is unsupported, and CocoaPods lists 6.24.1 as its latest available version because new versions cannot currently be published there.

Getting started

1. Open the GRDB.swift GitHub repository
2. Add GRDB.swift through Swift Package Manager, CocoaPods, or manual project integration
3. Confirm your project meets the stated Swift, Xcode, SQLite, and platform requirements
4. Configure a SQLite database and use SQL, queries, or Swift record persistence
5. Add migrations, observation integration, or SQLCipher encryption as needed

Verdict

Pick GRDB.swift for a Swift application that needs direct SQLite work, migrations, concurrency, and observation integrations without a license fee. It is especially suitable when Swift Package Manager or manual integration fits your project. Look elsewhere if you require Carthage, officially maintained Linux support, or newly published CocoaPods versions.
