Swift compatible?

[vin-the-dev]

I tried it in my swift project and it seems to crash every time, I tried both createPDFWithHTML and NDHTMLtoPDF.createPDFWithHTML, with no luck

let PDFCreator = NDHTMLtoPDF.createPDFWithHTML(htmlString.readString(),
baseURL: NSURL(fileURLWithPath: htmlString.path_string),
pathForPDF: toFile,
pageSize: CGSizeMake(595.2,841.8),
margins: UIEdgeInsetsMake(10, 5, 10, 5),
successBlock: nil,
errorBlock: nil)

    print("open " + toFile)

    NDHTMLtoPDF.createPDFWithHTML(htmlString.readString(),
        baseURL: NSURL(fileURLWithPath: htmlString.path_string),
        pathForPDF: toFile,
        delegate: nil,
        pageSize: CGSizeMake(595.2,841.8),
        margins: UIEdgeInsetsMake(10, 5, 10, 5))
