func chilkatTest() {

    // ...

    // ------------------------------------------------------------------------
    // The FetchSingle method is deprecated:

    var emailObj: CkoEmail? = imap.fetchSingle(1, bUid: false)
    if imap.lastMethodSuccess == false {
        print("\(imap.lastErrorText!)")
        return

    emailObj = nil

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

    let email = CkoEmail()!
    var success: Bool = imap.fetchEmail(headerOnly, msgId: 1, bUid: false, email: email)

        print("\(imap.lastErrorText!)")
        return
    }
