(Swift 2) Ftp2 Debug Log File Path

Demonstrates how to use the DebugLogFilePath property to get information if a Chilkat method crashes or hangs.

func chilkatTest() {
    let ftp = CkoFtp2()

    // ...
    // ...

    // Insert this code just before the method call that crashes or hangs.
    ftp.VerboseLogging = true
    ftp.DebugLogFilePath = "/some/file/path/sftp_debug_log.txt"

    // Make the call that crashes or hangs,
    // for example, if the method is PutFile:

    var remoteFilePath: String? = "..."
    var localFilePath: String? = "..."
    var success: Bool = ftp.PutFile(localFilePath, remoteFilename: remoteFilePath)

    // Note: If the method returns control to your application code, then it did not crash within Chilkat.
    // The DebugLogFilePath property causes all information that would be recorded in the LastErrorText to be emitted to the
    // log file (with immediate file write flushing, i.e. no buffering).  Thus, in a crash situation,
    // the log file will contain information up to the point of the crash.

    if success == false {
        print("\(ftp.LastErrorText)")
        return
    }
