What's UAParserSwift

UAParserSwift is a Swift-based library to parse User Agent string; it's a port of ua-parser-js by Faisal Salman created to be mainly used in Swift Server Side applications (Kitura, Vapor etc.). You can however use it on client side, all Apple's platforms are supported (iOS, macOS, tvOS and watchOS).

This library aims to identify detailed type of web browser, layout engine, operating system, cpu architecture, and device type/model, entirely from user-agent string with a relatively small footprint.

Other Libraries you may like

I'm also working on several other projects you may like. Take a look below:

| Library | Description | |-----------------|--------------------------------------------------| | SwiftDate | The best way to manage date/timezones in Swift | | Hydra | Write better async code: async/await & promises | | Flow | A new declarative approach to table managment. Forget datasource & delegates. | | SwiftRichString | Elegant & Painless NSAttributedString in Swift | | SwiftLocation | Efficient location manager | | SwiftMsgPack | Fast/efficient msgPack encoder/decoder |


How to use UAParserSwift

Usage of UAParserSwift is pretty simple; just allocate an UAParser object along with the User-Agent string you want to parse.

let parser = UAParser(agent: "Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_0 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7")

// Then call properties you want to read.
// Parsed data are cached and evaluated lazily in order to
// get the best performances.

let identified_os = parser.os
let identified_device = parser.device
let identified_engine = parser.engine
let identified_os = parser.os
let identified_cpu = parser.cpu

Now you can call one of these properties to get parsed data (all properties are lazy created in order to keep parser lightweight):

  • .browser: return a Browser object with the browser's properties: name, version
  • .device: return a Device object with device's informations: vendor,type,model
  • .engine: return an Engine object with information about browser's engine: name,version
  • .os: return an OS object with the information about host operation system: name,version
  • .cpu: return a CPU object with the informations about host's device architecture: identifier

Unit Tests

Unit Tests are available under the Tests directory; actually they are the same tests available for ua-parser-js and all are passed successfully.


This library is written for Swift 4.x.

Swift Package Manager - Swift Server Side (Kitura,Vapor...)

Meow requires Swift 4.0 or greater to work. This is the official way to install packages for Swift Server Side. In your Package.swift, add the following to your dependencies array:

.package(url: "https://github.com/malcommac/UAParserSwift.git", from: "1.0.1")

To your target, add the "UAParserSwift" dependency.

.target(name: "Application", dependencies: ["UAParserSwift", ...])

Using CocoaPods - Client Side

  1. Add the pod UAParserSwift to your Podfile.
pod 'UAParserSwift'

Run pod install from Terminal, then open your app's .xcworkspace file to launch Xcode.

Using Carthage - Client Side

  1. Add the malcommac/UAParserSwift project to your Cartfile.
github "malcommac/UAParserSwift"

1.0.1 - Nov 5, 2017

Fixed an issue in /Sources folder structure which prevent SwiftPM to add library's dependency to the host project.

1.0.0 - Nov 5, 2017

This is the first stable version. It requires Swift 4.0 and while the main scope is to be used on Swift Server Side (Vapor, Kitura and others) it can also be used on client side: all Apple platforms are currently supported.
