OSLog logging backend for swift-log.

If you're adding through Xcode's Swift Package Manager integration (Xcode 11 and higher), you can simply use:

https://github.com/chrisaljoudi/swift-log-oslog.git

And use 0.2.1 as the base version. If adding as a dependency in your Package.swift:

.package(url: "https://github.com/chrisaljoudi/swift-log-oslog.git", .from("0.2.1"))

During app startup/initialization:

import Logging
import LoggingOSLog

/// Configure `swift-log` logging system to use OSLog backend
LoggingSystem.bootstrap(LoggingOSLog.init)

Then use swift-log per usual, for example:

let logger = Logger(label: "com.yourcompany.yourawesomeapp")

/// ...

logger.info("Unified Logging is pretty cool.")
