WKWebView and XML/XSLT

Please: does WKWebView support XSLT rendering?

This is not working with WKWebView (it used to work with UIWebView):

self.webView.load(data, mimeType: "text/xml", characterEncodingName: "ISO-8859-1", baseURL: url)

where 
data = XML 
url = the complete path to the XSLT file 

Thank you!
