MongoKitten

MongoKitten is a native, production-ready MongoDB driver written in pure Swift. It is the fastest MongoDB driver available on any platform, while providing a great Swift API that is a joy to use.

Core features

Production ready
No complex setup procedure, just import and go
Extremely performant 🚀
Pure Swift
Great API
Fast with support for new MongoDB and Swift features and versions

Requirements

A MongoDB server (local or online) running MongoDB 2.6 or above. (MongoDB 3.2 or 3.4 is recommmended)
Swift 3.1 or greater

Linux requries the libssl-dev library to be installed.

Setting up MongoDB

Install MongoDB for Ubuntu, macOS or any other supported Linux Distro.

Alternatively; make use of a DAAS (Database-as-a-service) like Atlas, MLab, IBM Cloud or any other of the many services.

Getting started

Add MongoKitten to your Package.swift:

Swift 3: .Package(url: "https://github.com/OpenKitten/MongoKitten.git", majorVersion: 4)

Swift 4: .package(url: "https://github.com/OpenKitten/MongoKitten.git", from: "4.0.0")

For Swift 4 you also need to add MongoKitten to your target's dependencies and optionally ExtendedJSON for people using that:

.target(name: "MyTarget", dependencies: ["MongoKitten"])

After a swift package update, you can now use MongoKitten:

import MongoKitten

let myDatabase = try MongoKitten.Database("mongodb://localhost/my_database")
let myCollection = myDatabase["my_collection"]

for document in try myCollection.find("foo" > 42) {
    // do something with document
}

For more information on how to use MongoKitten, visit the documentation.

Building for performance

Always compile MongoKitten in release mode for production and benchmarks. MongoKitten has proven to be 100-200x faster on release mode compared to debug compilation. Both Xcode and SPM use debug compilation by default.

swift build -c release
