### During Development: Colored Logging to Xcode Console via OSLog API or Print
|
||

|
||
|
||
|
||
#### In Xcode 15
|
||
```Swift
|
||
|
||
// use Apple's fancy OSLog API:
|
||
let console = ConsoleDestination()
|
||
console.logPrintWay = .logger(subsystem: "Main", category: "UI")
|
||
|
||
// or use good ol' "print" (which is the default):
|
||
let console = ConsoleDestination()
|
||
console.logPrintWay = .print
|
||
```
|
||
#### In Xcode 8
|
||
[Learn more](http://docs.swiftybeaver.com/article/9-log-to-xcode-console) about colored logging to Xcode 8 Console with Swift 3, 4 & 5. For Swift 2.3 [use this Gist](https://gist.github.com/skreutzberger/7c396573796473ed1be2c6d15cafed34). **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](http://docs.swiftybeaver.com/article/10-log-to-file) about logging to file which is great for Terminal.app fans or to store logs on disk.
|
||
|
||
<br/>
|
||
|
||
### 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](https://github.com/SwiftyBeaver/SwiftyBeaver/blob/master/Sources/GoogleCloudDestination.swift) is just another customized logging format that adds the powerful functionality of automatic server-side Swift logging when hosted on Google Cloud Platform.

### Carthage
|
||
|
||
You can use [Carthage](https://github.com/Carthage/Carthage) to install SwiftyBeaver by adding that to your Cartfile:
|
||
|
||
Swift 4 & 5:
|
||
|
||
```Swift
|
||
github "SwiftyBeaver/SwiftyBeaver"
|
||
```
|
||

||
<br/>
|
||
|
||
### Swift Package Manager
|
||
|
||
For [Swift Package Manager](https://swift.org/package-manager/) add the following package to your Package.swift file. Just Swift 4 & 5 are supported:
|
||
|
||
```Swift
|
||
.package(url: "https://github.com/SwiftyBeaver/SwiftyBeaver.git", .upToNextMajor(from: "2.0.0")),
|
||
```
|
||
|
||
<br/>
|
||
|
||
### CocoaPods
|
||
|
||
To use [CocoaPods](https://cocoapods.org) just add this to your Podfile:
|
||
|
||
Swift 4 & 5:
|
||
|
||
```Swift
|
||
pod 'SwiftyBeaver'
|
||
```
|
||
|
||
Swift 3:
|
||
|
||
```Ruby
|
||
target 'MyProject' do
|
||
use_frameworks!
|
||
|
||
# Pods for MyProject
|
||
pod 'SwiftyBeaver', '~> 1.8.4'
|
||
end
|
||
```
|
||
|
||
Swift 2:
|
||
|
||
```Ruby
|
||
target 'MyProject' do
|
||
use_frameworks!
|
||
|
||
# Pods for MyProject
|
||
pod 'SwiftyBeaver', '~> 0.7'
|
||
end
|
||
|
||
post_install do |installer|
|
||
installer.pods_project.build_configurations.each do |config|
|
||
# Configure Pod targets for Xcode 8 with Swift 2.3
|
||
config.build_settings['SWIFT_VERSION'] = '2.3'
|
||
end
|
||
end
|
||
```
|
||
|
||
<br/>
|
||
<br/>
|
||
|
||
## 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 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
|
||
|
||
// 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"
|
||
|
||
// In Xcode 15, specifying the logging method as .logger to display color, subsystem, and category information in the console.(Relies on the OSLog API)
|
||
console.logPrintWay = .logger(subsystem: "Main", category: "UI")
|
||
// If you prefer not to use the OSLog API, you can use print instead.
|
||
// console.logPrintWay = .print
|
||
|
||
// add the destinations to SwiftyBeaver
|
||
log.addDestination(console)
|
||
log.addDestination(file)
|
||
|
||
// 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", context: 123) // "DEBUG: age 123"
|
||
log.info("my data", context: [1, "a", 2]) // "INFO: my data [1, \"a\", 2]"
|
||
|
||
```
|
||
|
||
Alternatively, if you are using SwiftUI, consider using the following setup:
|
||
|
||
```swift
|
||
import SwiftyBeaver
|
||
let logger = SwiftyBeaver.self
|
||
|
||
@main
|
||
struct yourApp: App {
|
||
|
||
init() {
|
||
let console = ConsoleDestination()
|
||
logger.addDestination(console)
|
||
// etc...
|
||
}
|
||
|
||
var body: some Scene {
|
||
WindowGroup {
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
<br/>
|
||
<br/>
|
||
|
||
## Server-side Swift
|
||
|
||
We ❤️ server-side Swift 4 & 5 and SwiftyBeaver support it **out-of-the-box**! Try for yourself and run SwiftyBeaver inside a Ubuntu Docker container. Just install Docker and then go to your project folder on macOS or Ubuntu and type:
|
||
|
||
```shell
|
||
# create docker image, build SwiftyBeaver and run unit tests
|
||
docker run --rm -it -v $PWD:/app swiftybeaver /bin/bash -c "cd /app ; swift build ; swift test"
|
||
|
||
# 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](https://github.com/vapor/vapor) you can use **[our Vapor logging provider](https://github.com/SwiftyBeaver/SwiftyBeaver-Vapor)** which makes server logging awesome again 🙌
