func application(_ application: UIApplication,
                 didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
    // Set the log rotation count. (default: 10files)
    LSSLogger.configureLogRotationCount(count: 5)
    
    #if RELEASE
    
    // For release builds, logs are not output to the console.
    LSSLogger.outputToConsoleEnabled(isEnabled: false)
    
    // For release builds, logs are not output to files.
    LSSLogger.outputToFileEnabled(isEnabled: false)
    #endif
    
    return true
}

And, Active Compilation Conditions is as follows:

Usage

func debugLogDemo() {
    // Output to the console.
    LSSLogger.console.debug()

    // Output to the file.
    LSSLogger.file.info(message: "bar")
    LSSLogger.file.warning()
    LSSLogger.file.error()
