func chilkatTest() {
    var success: Bool = false

    let sftp = CkoSFtp()!

    // ...
    // ...

    // ------------------------------------------------------------------------
    // The ReadDir method is deprecated:

    var dirObj: CkoSFtpDir? = sftp.readDir()
    if sftp.lastMethodSuccess == false {
        print("\(sftp.lastErrorText!)")
        return
    }

    // ...
    // ...

    dirObj = nil

    // ------------------------------------------------------------------------
    // Do the equivalent using ReadDirListing.
    // Your application creates a new, empty SFtpDir object which is passed 
    // in the last argument and filled upon success.

    let dirOut = CkoSFtpDir()!
    success = sftp.readDirListing(dirOut)
    if success == false {
        print("\(sftp.lastErrorText!)")
        return
    }
