BSON

A native, fast BSON library for Swift, written in Swift.

BSON is parsed and generated as specified for version 1.0 of the BSON specification.

Compatibility

Operating systems

All versions starting with BSON 1.3 are compatible with OS X and Ubuntu 15.10. Other operating systems may work but are untested.

Swift Version

We support the Swift version specified in .swift_version, which most of the time is the latest version of Swift when a version is released.

For every new Swift snapshot we release a new minor version.

Usage

The supported method for using this library is trough the Swift Package manager, like this:

import PackageDescription

let package = Package(
    name: "MyApp",
    dependencies: [.Package(url: "https://github.com/OpenKitten/BSON.git", majorVersion: 4)]
)

Basic Usage

// Create a document using a dictionary literal
let document: Document = [
            "hello": "I am a BSON document",
            "temperature": 42.5
        ]

// Retreive the BSON data, ready for storing or sending over the network
let data = document.bsonData // Array of [UInt8]

// Initialize a document using a [UInt8]
let sameDocument = try! Document(data: data)

// Do something with the data
let temperature = document["temperature"] as Double?

// Use the temperature

Embedded documents

let document: Document = [
            "subdocument": ["hello": "sample"] as Document,
            "anothersubdocument": [81.2, "cheese"] as Document // an array is also an embedded document
        ]

Comparing

document["double"] == document["int64"] // true for Double(0) == Int64(0)
document["double"] === document["int64"] // false for Double(0) === Int64(0)
