Willow is a lightweight, powerful logging library written in Swift by Nike. It supports multiple log levels, custom writers and modifiers via dependency injection, and thread-safe synchronous or asynchronous log output.
Use cases
- add logging to an iOS app in Swift
- log messages without blocking the main thread
- write log output to multiple destinations
- create custom log levels and writers
- share a logger across frameworks
- prevent garbled log output in concurrent code
When to choose
- you need a lightweight Swift logging library for Apple platforms
- you want configurable sync/async logging with thread-safe output
- you need custom log writers or modifiers via dependency injection
When to avoid
- you need structured or distributed logging with backends like ELK or Datadog
- your project is not on Apple platforms or Swift
- you need a logging solution with built-in log shipping or aggregation
