func chilkatTest() {
    let mailman = CkoMailMan()!

    // ...

    let saUidls = CkoStringArray()!

    stUidls.append("aaa")

    // ------------------------------------------------------------------------
    // The FetchMultiple method is deprecated:

    var bundleObj: CkoEmailBundle? = mailman.fetchMultiple(saUidls)
    if mailman.lastMethodSuccess == false {
        print("\(mailman.lastErrorText!)")
        return
    }

    // ...
    // ...

    bundleObj = nil

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

    var headersOnly: Bool = false
    // Irrelevant because we are not downloading headers-only.
    var numBodyLines: Int = 0

    let bundleOut = CkoEmailBundle()!
    var success: Bool = mailman.fetchUidlSet(stUidls, headersOnly: headersOnly, numBodyLines: numBodyLines, bundle: bundleOut)
    if success == false {
        print("\(mailman.lastErrorText!)")
