# Integrating with logging tools
There are a lots of good logging tools for iOS. So we'll leave that choice to you. ZcashLightClientKit relies on a simple protocol to bubble up logs to client applications, which is called `Logger` (kudos for the naming originality...)
```
public protocol Logger {
func debug(_ message: String, file: String, function: String, line: Int)
func info(_ message: String, file: String, function: String, line: Int)
func event(_ message: String, file: String, function: String, line: Int)
func warn(_ message: String, file: String, function: String, line: Int)
func error(_ message: String, file: String, function: String, line: Int)
}
```
To enable logging you need to do 2 simple steps:
1. have one class conform the `Logger` protocol
2. inject that logger when creating the `Initializer`
For more details look the Sample App's `AppDelegate` code.
# Swiftlint
We don't like reinveing the wheel, so be gently borrowed swift lint rules from AirBnB which we find pretty cool and reasonable.
