func chilkatTest() {
    let zip = CkoZip()!

    // ...
    // ...
    var pattern: String? = "*.txt"

    // ------------------------------------------------------------------------
    // The FirstMatchingEntry method is deprecated:

    var entryObj: CkoZipEntry? = zip.first(matchingEntry: pattern)
    if zip.lastMethodSuccess == false {
        print("\(zip.lastErrorText!)")
        return
    }

    // ...
    // ...

    entryObj = nil

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

    let ze = CkoZipEntry()!
    var success: Bool = zip.entry(matching: pattern, entry: ze)
    if success == false {
        print("\(zip.lastErrorText!)")
        return
    }
