MongoSwift
The official MongoDB driver for Swift applications on macOS and Linux, providing async and sync APIs.
What is MongoSwift?
MongoSwift is the official MongoDB driver for Swift, enabling developers to interact with MongoDB databases from server-side Swift applications. It provides a native Swift interface for performing database operations, supporting both asynchronous and synchronous programming models. However, development has been paused, meaning no further updates, bug fixes, or maintenance are provided by the project.
Server-side Swift developers building applications on macOS or Linux that require MongoDB database interactions, particularly those using frameworks like Kitura, Vapor, or Perfect.
Developers choose MongoSwift for its idiomatic Swift API, full compatibility with MongoDB features, and support for modern Swift concurrency models like async/await. As the official driver, it offers reliability and seamless integration with MongoDB's ecosystem, though it is currently in a maintenance-only state.
Overview
The official MongoDB driver for Swift
Use Cases
Best For
- Building server-side Swift applications that require asynchronous database operations using async/await.
- Integrating MongoDB with popular Swift web frameworks like Kitura, Vapor, or Perfect.
- Developing cross-platform Swift applications that need to run on both macOS and Linux.
- Working with BSON documents natively in Swift through the integrated BSON library.
- Using synchronous MongoDB operations in Swift scripts or simpler server applications.
- Leveraging SwiftNIO's EventLoopFuture for asynchronous database interactions in event-driven architectures.
Not Ideal For
- Projects requiring active maintenance, bug fixes, or updates for new Swift or MongoDB versions
- Teams needing official support or documentation changes, as development is indefinitely paused
- Applications built on Swift frameworks that depend on drivers with ongoing community or vendor support
Pros & Cons
Pros
Supports Swift's async/await concurrency model for asynchronous database operations, with clear examples in the README for connecting and querying using async/await.
Offers both synchronous and asynchronous APIs, including EventLoopFuture integration, catering to diverse use cases from scripting to event-driven apps, as demonstrated in the usage examples.
Includes a native BSON implementation for seamless document manipulation in Swift, shown in code snippets for creating, modifying, and filtering BSON documents.
Runs on both macOS and Linux, enabling server-side Swift development across operating systems, as stated in the key features and installation requirements.
Cons
No further development, bug fixes, enhancements, or maintenance are provided, making it risky for projects needing long-term viability or compatibility with evolving Swift/MongoDB ecosystems.
Requires manual installation of external system libraries on Linux, adding an extra setup step compared to macOS, as outlined in the installation instructions.
Built exclusively on SwiftNIO 2, which may limit compatibility with frameworks or projects using older or newer versions, as noted in the framework integration section.
