It leverages CocoaTouch modules and is less invasive than CocoaPods. + +To install with Carthage, follow the instruction on [Carthage](https://github.com/Carthage/Carthage) + +Cartfile +``` +github "CocoaLumberjack/CocoaLumberjack" +``` + + +### 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: + +```swift +.package(url: "https://github.com/CocoaLumberjack/CocoaLumberjack.git", from: "3.7.0"), +``` + +Note that you may need to add both products, `CocoaLumberjack` and `CocoaLumberjackSwift` to your target since SPM sometimes fails to detect that `CocoaLumerjackSwift` depends on `CocoaLumberjack`. + +### Install manually + +If you want to install CocoaLumberjack manually, read the [manual installation](Documentation/GettingStarted.md#manual-installation) guide for more information. + +### Swift Usage + +Usually, you can simply `import CocoaLumberjackSwift`. If you installed CocoaLumberjack using CocoaPods, you need to use `import CocoaLumberjack` instead. + +```swift +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") +``` + +### Obj-C usage + +If you're using Lumberjack as a framework, you can `@import CocoaLumberjack;`. +Otherwise, `#import ` + +```objc +[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"); +``` +### Objective-C ARC Semantic Issue + +When integrating Lumberjack into an existing Objective-C it is possible to run into `Multiple methods named 'tag' found with mismatched result, parameter type or attributes` build error. + +Add `#define DD_LEGACY_MESSAGE_TAG 0` before importing CocoaLumberjack or add `#define DD_LEGACY_MESSAGE_TAG 0` or add `-DDD_LEGACY_MESSAGE_TAG=0` to *Other C Flags*/*OTHER_CFLAGS* in your Xcode project. + +## [swift-log](https://github.com/apple/swift-log) backend + +CocoaLumberjack also ships with a backend implementation for [swift-log](https://github.com/apple/swift-log). +Simply add CocoaLumberjack as dependency to your SPM target (see above) and also add the `CocoaLumberjackSwiftLogBackend` product as dependency to your target. + +You can then use `DDLogHandler` as backend for swift-log, which will forward all messages to CocoaLumberjack's `DDLog`. You will still configure the loggers and log formatters you want via `DDLog`, but writing log messages will be done using `Logger` from swift-log. + +In your own log formatters, you can make use of the `swiftLogInfo` property on `DDLogMessage` to retrieve the details of a message that is logged via swift-log. + + +## More information + +- read the [Getting started](Documentation/GettingStarted.md) guide, check out the [FAQ](Documentation/FAQ.md) section or the other [docs](Documentation/) +- if you find issues or want to suggest improvements, create an issue or a pull request +- for all kinds of questions involving CocoaLumberjack, use the [Google group](https://groups.google.com/group/cocoalumberjack) or StackOverflow (use [#lumberjack](https://stackoverflow.com/questions/tagged/lumberjack)). + + +## CocoaLumberjack 3 + +### Migrating to 3.x + +* To be determined + +## Features + +### 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). + +## Documentation + +- **[Get started using Lumberjack](Documentation/GettingStarted.md)**
