Log 📝

Lightweight, pluggable, pure Swift logging library

Installation

You can install Log 📝 with SPM

1. Add or amend a Package.swift
2. Add this dependency .package(url: "https://github.com/dalu93/Log.git", from: "1.0.0")
3. Then import Log in your code and start using it 🎉

Usage

log.error("something wrong happened")

Easy right? By default, Log comes with a set of LogLevels which should cover, more or less, all the use cases: debug, info, notice, warning and error. It also provides few utility methods that you can access as below:

log.debug("message", isVerbose: true)
log.info("message")
log.notice("message")
log.warning("message")
log.error("message")

Destinations

By using the default log instance, your logs are going to be sent to terminal output. If you want to change this behavior, define your own Destination by confirming to LogDestination protocol

struct LocalFileDestination: LogDestination {
    func log(_ message: @autoclosure () -> String) {
        // log to file here...
    }
}

And then, initialize your own Logger instance

let logger = Logger(
    destinations: [
        LocalFileDestination(),
        TerminalDestination()
    ],
    isVerbose: false
)

This code will send the logs to each LogDestination which is passed to the Logger instance.
