# apple/swift-log

This repository contains a logging API implementation for Swift.

## Quick Start

The following snippet shows how to add SwiftLog to your Swift Package:

```swift // swift-tools-version: 6.1 import PackageDescription

let package = Package(     name: "YourApp",     dependencies: [         .package(url: "https://github.com/apple/swift-log", from: "1.6.0")     ],     targets: [         .target(             name: "YourApp",             dependencies: [                 .product(name: "Logging", package: "swift-log")             ]         )     ] ) ```

Then start logging:

```swift import Logging

// Create a logger let logger = Logger(label: "com.example.YourApp")

// Log at different levels logger.info("Application started") logger.warning("This is a warning") logger.error("Something went wrong", metadata: ["error": "\(error)"])

// Add metadata for context var requestLogger = logger requestLogger[metadataKey: "request-id"] = "\(UUID())" requestLogger.info("Processing request") ```

## Available log handler backends

The community has built numerous specialized logging backends.

A great way to discover available log backend implementations is searching the [Swift Package Index](https://swiftpackageindex.com/search?query=swift-log) for the `swift-log` keyword.
