Download POP3 Email using UIDLs

Demonstrates how to download POP3 email by first getting the complete set of UIDLs and then downloading email by calling FetchByUIDL for each UIDL. Swift

func chilkatTest() {
    var success: Bool = false

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

    // The mailman object is used for receiving (POP3) 
    // and sending (SMTP) email.
    let mailman = CkoMailMan()!

    // Set the POP3 server's hostname
    mailman.mailHost = "pop.example.com"

    // Set the POP3 login/password.
    mailman.popUsername = "myLogin"
    mailman.popPassword = "myPassword"

    let stUidls = CkoStringTable()!
    success = mailman.fetchUidls(uidls: stUidls)
    if success == false {
        print("\(mailman.lastErrorText!)")
        return
    }

    let email = CkoEmail()!

    var count: Int = stUidls.count.intValue
    var i: Int = 0
    while i < count {
        // Download the full email.
        success = mailman.fetch(byUidl: stUidls.string(at: i), headerOnly: false, numBodyLines: 0, email: email)
        if success == false {
            print("\(mailman.lastErrorText!)")
            return
        }

        print("\(i)")
        print("From: \(email.from!)")
        print("Subject: \(email.subject!)")

        i = i + 1
    }

    mailman.pop3EndSession()
