DaveWoodCom / XCGLogger

A debug log framework for use in Swift projects. Allows you to log details to the console (and optionally a file), just like you would have with NSLog() or print(), but with additional information, such as the date, function name, filename and line number.

File append marker written twice

Hi,
when I'm using shouldAppend: true option for FileDestination, after each restart file contains two append markers. That should be one append marker for one app restart. I've tried configuring XCGLogger in different ways and places, and always got the same results. The simplest configuration that causes that issue (in AppDelegate file):

let log: XCGLogger = {
    let log = XCGLogger(identifier: "advancedLogger", includeDefaultDestinations: false)
    let logPath: URL = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask).first!.appendingPathComponent("XCGLogger_Log.txt")
    let fileDestination = AutoRotatingFileDestination(owner: log, writeToFile: logPath, identifier: "advancedLogger.fileDestination", shouldAppend: true, appendMarker: "-- Relauched App --")
    fileDestination.outputLevel = .debug
    log.add(destination: fileDestination)
    return log
}()

Marker -- Relauched App -- is written always two times for each app restart.

Example file content after one app restart:
