Automatic Swift network activity logger for iOS or OSX.

Cocoapods Carthage compatible MIT iOS

Timberjack is a simple, unintrusive network activity logger. Log every request your app makes, or limit to only those using a certain NSURLSession if you’d prefer. It also works with Alamofire, if that’s your thing.

Note, Timberjack is written in Swift 2.0, so you’ll need Xcode7 to build. If you’re using Swift 1.2, there’s a compatible version on the swift-1.2 branch

  • Enable logging across your app with just 1 line of code
  • Verbose and Light debugging modes
  • Works with NSURLSession, NSURLConnection, Alamofire and pretty much any networking framework
  • Pretty printed JSON responses
  • Useful for debugging and development, but probably best not to ship your app with verbose logging.


Timberjack is installed as an embedded framework, and such requires at least iOS8. If you require iOS7 compatibility, simply drag the Timberjack.swift file into your own project.


Add the following to your Podfile

platform :ios, '8.0'

pod 'Timberjack'

Then install with pod install


Add the following to your Cartfile

github "andysmart/Timberjack" >= 0.0.1


Nice and easy, just register when your app loads, and Timberjack will monitor and log any requests you make via NSURLSession or NSURLConnection.

import UIKit
import Timberjack

class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        Timberjack.register() //Register Timberjack to log all requests

        return true

Using with Alamofire

Due to the way Alamofire uses NSURLSession, you’ll need to do a little more than the standard installation to monitor all requests. The simplest way to do this is to create a subclass of Manager to handle your requests, then just use this in place of Alamofire.request().

import Alamofire
import Timberjack

class HTTPManager: Alamofire.Manager {
    static let sharedManager: HTTPManager = {
        let configuration = Timberjack.defaultSessionConfiguration()
        let manager = HTTPManager(configuration: configuration)
        return manager


Timberjack has two modes: Verbose and Light. The default style is Verbose. To change this, just set it appropriately.

Timberjack.logStyle = .Verbose //Either .Verbose, or .Light

Unfortunately, due to a limitation in NSURLProtocol, Timberjack is unable to log the HTTP body of a request, see This radar for more details
