(Swift 2) Using the FTP Session Log

The Chilkat FTP component can keep a session log if the KeepSessionLog property is turned on. This is helpful in debugging problems. Chilkat support will usually ask for a session log when working to resolve your problem, because it contains a log of the exact commands sent to the FTP server, and the exact responses received.

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let ftp = CkoFtp2()

    ftp.Hostname = "ftp.example.com"
    ftp.Username = "login"
    ftp.Password = "password"

    // Set the KeepSessionLog property in order to keep a session log.
    // The session log will continuously grow in memory.  The
    // ClearSessionLog method may be called to clear it.  The session
    // logging may be turned on/off at any point.
    ftp.KeepSessionLog = true

    // Connect and login to the FTP server.
    var success: Bool = ftp.Connect()
    if success != true {
        print("\(ftp.LastErrorText)")
        return
    }

    // Change to the remote directory where the existing file is located.
    success = ftp.ChangeRemoteDir("junk")
    if success != true {
        print("\(ftp.LastErrorText)")
        return
    }

    // To clear the SessionLog at any point, call ClearSessionLog:
    // call ftp.ClearSessionLog();

    // Append moreHamlet.txt to hamlet.txt on the FTP server.
    var localFilename: String? = "moreHamlet.txt"
    var remoteFilename: String? = "hamlet.txt"

    success = ftp.AppendFile(localFilename, remoteFilename: remoteFilename)
    if success != true {
        print("\(ftp.LastErrorText)")
        return
    }

    success = ftp.Disconnect()

    // Display the entire session log:
    print("\(ftp.SessionLog)")

    print("File Appended!")
