(Swift) Iterate over Matching Filenames

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files.

Note: This example requires Chilkat v11.0.0 or greater.

    // Open a .zip containing PEM files, among other things..
    success = zip.open("qa_data/certs/thawte-roots.zip")
    if success == false {

        // Get the uncommpressed contents of the entry:
        pemStr = entry.unzip(toString: 0, srcCharset: "utf-8")
        print("\(pemStr!)")

        bHasMoreMatches = entry.getNextMatch(pattern)
