Cocoalumberjack is a robust logging framework designed for macOS and iOS applications. It enables developers to easily log and debug their code, improving the overall development process and quality of the application.

  • Highly efficient and customizable logging
  • Flexible and extensible architecture
  • Supports various log formats (plain text, JSON, etc.)
  • Synchronous and asynchronous logging options
  • Multi-threading support for improved performance
  • Dynamic log level configuration
  • Powerful log filtering and searching capabilities
  • Comprehensive documentation and community support

Follow the steps below to install Cocoalumberjack in your project:

  1. Open your project in Xcode
  2. Go to the menu and select “File” -> “Swift Packages” -> “Add Package Dependency”
  3. In the Package dependency dialog, enter the repository URL: “”
  4. Choose the desired version or branch
  5. Click “Next” and select the target where you want to add Cocoalumberjack
  6. Click “Finish” to add the package to your project

To configure Cocoalumberjack, add the following code to your application’s startup process:

import CocoaLumberjack

func configureLogging() {
DDLog.add(DDOSLogger.sharedInstance) // Console logger
// Add additional loggers if required

DDLogDebug("Logging configured successfully")

// Call configureLogging() at the beginning of your application's lifecycle

This code snippet adds a basic console logger. You can customize the configuration by adding or removing loggers based on your requirements. Refer to the Cocoalumberjack documentation for more advanced configurations and options.

Using Cocoalumberjack is simple. Follow the example below to start logging:

import CocoaLumberjack

class MyViewController: UIViewController {
override func viewDidLoad() {

DDLogDebug("This is a debug log")
DDLogInfo("This is an info log")
DDLogWarn("This is a warning log")
DDLogError("This is an error log")

By using different log level functions (debug, info, warn, error), you can categorize your logs based on their severity. This helps in identifying and troubleshooting issues more effectively.
