(Swift 2) Secure IMAP over TLS/SSL

To communicate with an IMAP server over TLS/SSL, simply set the Ssl and Port properties. The remainder of your code is the same as with non-SSL.

    let imap = CkoImap()

    // To use a secure TLS/SSL connection, set the Ssl property and the port:
    imap.Ssl = true
    // The typical port for IMAP SSL is 993
    imap.Port = 993

    // Connect to an IMAP server.
    var success: Bool = imap.Connect("imap.someMailServer.com")
    if success != true {
        print("\(imap.LastErrorText)")
        return
    }

    // Login
    success = imap.Login("myLogin", password: "myPassword")
    if success != true {
        print("\(imap.LastErrorText)")
        return
    }

    // Select an IMAP mailbox
    success = imap.SelectMailbox("Inbox")
    if success != true {
        print("\(imap.LastErrorText)")
        return
    }

    // We can choose to fetch UIDs or sequence numbers.
    var fetchUids: Bool = true
    // Get the message IDs of all the emails in the mailbox
    var messageSet: CkoMessageSet? = imap.Search("ALL", bUid: fetchUids)
    if imap.LastMethodSuccess == false {
        print("\(imap.LastErrorText)")
        return
    }

    // Fetch the emails into a bundle object:
    var bundle: CkoEmailBundle? = imap.FetchBundle(messageSet)
    if imap.LastMethodSuccess == false {
        messageSet = nil
        print("\(imap.LastErrorText)")
        return
    }

    // Loop over the bundle and display the FROM and SUBJECT of each.
    var i: Int = 0
    var numEmails: Int = bundle!.MessageCount.intValue
    while i < numEmails {
        var email: CkoEmail? = bundle!.GetEmail(i)
        print("\(email!.From)")
        print("\(email!.Subject)")
        print("--")
        email = nil
        i = i + 1
    }

    // Disconnect from the IMAP server.
    success = imap.Disconnect()

    messageSet = nil
    bundle = nil
