SwiftLog is Apple's logging API package for Swift, providing a unified, performant logging facade that libraries and applications can adopt across the Swift ecosystem. It is an API-only package meant to be paired with community-maintained logging backend implementations (LogHandler) for production use.

Use cases

• add structured logging to a Swift server application
• standardize logging across Swift libraries and frameworks
• swap logging backends without changing application code
• attach metadata like request IDs to log messages
• log at different levels (info, warning, error) in Swift apps

When to choose

• you are building Swift server-side or application code and need a standard logging API
• you are a library author who wants consumers to control the logging backend
• you want an SSWG-graduated, Apple-maintained package with broad platform support

When to avoid

• you need a batteries-included logging implementation with output formatting out of the box
• your project is not in Swift
• you need a specific backend feature that requires using a concrete logging library directly
