CocoaLumberjack alternatives and similar libraries
Based on the "Logging" category
9.2 3.9 L3 CocoaLumberjack VS XCGLoggerA debug log framework for use in Swift projects. Allows you to log details to the console (and optionally a file), just like you would have with NSLog or println, but with additional information, such as the date, function name, filename and line number.

CocoaLumberjack is a fast & simple, yet powerful & flexible logging framework for Mac and iOS.
How to get started
First, install CocoaLumberjack via CocoaPods, Carthage, Swift Package Manager or manually.
DDOSLogger for iOS 10 and later, or
DDASLLogger for earlier versions to begin logging messages.
platform :ios, '8.0' target 'SampleTarget' do use_frameworks! pod 'CocoaLumberjack/Swift' end
Swift is a subspec which will include all the Obj-C code plus the Swift one, so this is sufficient.
For more details about how to use Swift with Lumberjack, see this conversation.
For Objective-C use the following:
platform :ios, '8.0' target 'SampleTarget' do pod 'CocoaLumberjack' end
Carthage is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods.
To install with Carthage, follow the instruction on Carthage
Swift Package Manager
As of CocoaLumberjack 3.6.0, you can use the Swift Package Manager as integration method. If you want to use the Swift Package Manager as integration method, either use Xcode to add the package dependency or add the following dependency to your Package.swift:
.package(url: "https://github.com/CocoaLumberjack/CocoaLumberjack.git", from: "3.6.0"),
If you want to install CocoaLumberjack manually, read the manual installation guide for more information.
Usually, you can simply
import CocoaLumberjackSwift. If you installed CocoaLumberjack using CocoaPods, you need to use
import CocoaLumberjack instead.
DDLog.add(DDOSLogger.sharedInstance) // Uses os_log let fileLogger: DDFileLogger = DDFileLogger() // File Logger fileLogger.rollingFrequency = 60 * 60 * 24 // 24 hours fileLogger.logFileManager.maximumNumberOfLogFiles = 7 DDLog.add(fileLogger) ... DDLogVerbose("Verbose") DDLogDebug("Debug") DDLogInfo("Info") DDLogWarn("Warn") DDLogError("Error")
If you're using Lumberjack as a framework, you can
[DDLog addLogger:[DDOSLogger sharedInstance]]; // Uses os_log DDFileLogger *fileLogger = [[DDFileLogger alloc] init]; // File Logger fileLogger.rollingFrequency = 60 * 60 * 24; // 24 hour rolling fileLogger.logFileManager.maximumNumberOfLogFiles = 7; [DDLog addLogger:fileLogger]; ... DDLogVerbose(@"Verbose"); DDLogDebug(@"Debug"); DDLogInfo(@"Info"); DDLogWarn(@"Warn"); DDLogError(@"Error");

- To be determined
Lumberjack is Fast & Simple, yet Powerful & Flexible.
It is similar in concept to other popular logging frameworks such as log4j, yet is designed specifically for Objective-C, and takes advantage of features such as multi-threading, grand central dispatch (if available), lockless atomic operations, and the dynamic nature of the Objective-C runtime.
Lumberjack is Fast
In most cases it is an order of magnitude faster than NSLog.
Lumberjack is Simple
It takes as little as a single line of code to configure lumberjack when your application launches. Then simply replace your NSLog statements with DDLog statements and that's about it. (And the DDLog macros have the exact same format and syntax as NSLog, so it's super easy.)
Lumberjack is Powerful:
One log statement can be sent to multiple loggers, meaning you can log to a file and the console simultaneously. Want more? Create your own loggers (it's easy) and send your log statements over the network. Or to a database or distributed file system. The sky is the limit.
Lumberjack is Flexible:
Configure your logging however you want. Change log levels per file (perfect for debugging). Change log levels per logger (verbose console, but concise log file). Change log levels per xcode configuration (verbose debug, but concise release). Have your log statements compiled out of the release build. Customize the number of log levels for your application. Add your own fine-grained logging. Dynamically change log levels during runtime. Choose how & when you want your log files to be rolled. Upload your log files to a central server. Compress archived log files to save disk space...
This framework is for you if:
- You're looking for a way to track down that impossible-to-reproduce bug that keeps popping up in the field.
- You're frustrated with the super short console log on the iPhone.
- You're looking to take your application to the next level in terms of support and stability.
- You're looking for an enterprise level logging solution for your application (Mac or iPhone).
- Get started using Lumberjack
- Different log levels for Debug and Release builds
- Different log levels for each logger
- Use colors in the Xcode debugging console
- Write your own custom formatters
- Analysis of performance with benchmarks
- Common issues you may encounter and their solutions
