During Development: Colored Logging to Xcode Console

Learn more about colored logging to Xcode 8 Console with Swift 3 & 4. For Swift 2.3 use this Gist. No need to hack Xcode 8 anymore to get color. You can even customize the log level word (ATTENTION instead of ERROR maybe?), the general amount of displayed data and if you want to use the 💜s or replace them with something else 😉

During Development: Colored Logging to File

Learn more about logging to file which is great for Terminal.app fans or to store logs on disk.

On Release: Encrypted Logging to SwiftyBeaver Platform

Learn more about logging to the SwiftyBeaver Platform during release!

Browse, Search & Filter via Mac App


Conveniently access your logs during development & release with our free Mac App.

On Release: Enterprise-ready Logging to Your Elasticsearch & Kibana (on-premise)

Learn more about legally compliant, end-to-end encrypted logging to Elasticsearch with SwiftyBeaver Enterprise. Install via Docker or manual, fully-featured free trial included!

Google Cloud & More

You can fully customize your log format, turn it into JSON, or create your own destinations. For example our Google Cloud Destination is just another customized logging format which adds the powerful functionality of automatic server-side Swift logging when hosted on Google Cloud Platform.


  • For Swift 3 & 4 install the latest SwiftyBeaver version
  • For Swift 2 install SwiftyBeaver 0.7.0


You can use Carthage to install SwiftyBeaver by adding that to your Cartfile:

Swift 3 & 4: ``` Swift github "SwiftyBeaver/SwiftyBeaver"

Swift 2:

Swift github "SwiftyBeaver/SwiftyBeaver" ~> 0.7


### Swift Package Manager

For [Swift Package Manager](https://swift.org/package-manager/) add the following package to your Package.swift file. Just Swift 3 & 4 are supported:

Swift .Package(url: "https://github.com/SwiftyBeaver/SwiftyBeaver.git", majorVersion: 1)


### CocoaPods

We plan to discontinue the support for CocoaPods due to its issues with latest Xcode and Swift versions latest at the end of 2018. Please use Carthage or SPM instead to stay on top of new SwiftyBeaver releases.

To use [CocoaPods](https://cocoapods.org) just add this to your Podfile:

Swift 3 & 4:

Swift pod 'SwiftyBeaver'

Swift 2:

Ruby target 'MyProject' do use_frameworks!

# Pods for MyProject pod 'SwiftyBeaver', '~> 0.7' end

postinstall do |installer| installer.podsproject.buildconfigurations.each do |config| # Configure Pod targets for Xcode 8 with Swift 2.3 config.buildsettings['SWIFT_VERSION'] = '2.3' end end


## Usage

Add that near the top of your `AppDelegate.swift` to be able to use SwiftyBeaver in your whole project.

Swift import SwiftyBeaver let log = SwiftyBeaver.self

At the the beginning of your `AppDelegate:didFinishLaunchingWithOptions()` add the SwiftyBeaver log destinations (console, file, etc.), optionally adjust the [log format](http://docs.swiftybeaver.com//article/20-custom-format) and then you can already do the following log level calls globally:

Swift // add log destinations. at least one is needed! let console = ConsoleDestination() // log to Xcode Console let file = FileDestination() // log to default swiftybeaver.log file let cloud = SBPlatformDestination(appID: "foo", appSecret: "bar", encryptionKey: "123") // to cloud

// use custom format and set console output to short time, log level & message console.format = "$DHH:mm:ss$d $L $M" // or use this for JSON output: console.format = "$J"

// add the destinations to SwiftyBeaver log.addDestination(console) log.addDestination(file) log.addDestination(cloud)

// Now let’s log! log.verbose("not so important") // prio 1, VERBOSE in silver log.debug("something to debug") // prio 2, DEBUG in green log.info("a nice information") // prio 3, INFO in blue log.warning("oh no, that won’t be good") // prio 4, WARNING in yellow log.error("ouch, an error did occur!") // prio 5, ERROR in red

// log anything! log.verbose(123) log.info(-123.45678) log.warning(Date()) log.error(["I", "like", "logs!"]) log.error(["name": "Mr Beaver", "address": "7 Beaver Lodge"])

// optionally add context to a log message console.format = "$L: $M $X" log.debug("age", 123) // "DEBUG: age 123" log.info("my data", context: [1, "a", 2]) // "INFO: my data [1, \"a\", 2]"


## Server-side Swift

We ❤️ server-side Swift 3 & 4 and SwiftyBeaver supports it **out-of-the-box**! Try for yourself and run SwiftyBeaver inside a Ubuntu Docker container. Just install Docker and then go to your the project folder on macOS or Ubuntu and type:


create docker image, build SwiftyBeaver and run unit tests

swift build --clean && docker build --rm -t swiftybeaver .

optionally log into container to run Swift CLI and do more stuff

docker run --rm -it --privileged=true -v $PWD:/app swiftybeaver ```

Best: for the popular server-side Swift web framework Vapor you can use our Vapor logging provider which makes server logging awesome again 🙌
