CocoaLumberjack is a fast & simple, yet powerful & flexible logging framework for Mac and iOS.
for iOS 10 and later, or
for earlier versions to begin logging messages.
platform :ios, '8.0' target 'SampleTarget' do use\_frameworks! pod 'CocoaLumberjack/Swift' end
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: ```ruby 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
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
. If you installed CocoaLumberjack using CocoaPods, you need to use
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");
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.
In most cases it is an order of magnitude faster than NSLog.
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.)
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.
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...
The current version of Lumberjack requires: - Xcode 11 or later - Swift 5.0 or later - iOS 8 or later - macOS 10.10 or later - watchOS 3 or later - tvOS 9 or later
