UIWebView LoadData is not accepting Nil values for textEncodingName and baseURL

Question

Till Swift 1.2 version, UIWebView LoadData was accepting nil values, but Swift 2.0 is throwing error "Swift does not conform to protocol NilLateralConvertible".

Swift 1.2: Works fine

self.webView.loadData(tempData!, MIMEType: "application/pdf", textEncodingName: nil, baseURL: nil)

Swift 2.0: Throws error

self.webView.loadData(tempData!, MIMEType: "application/pdf", textEncodingName: nil, baseURL: nil)

Answer 1

This works for me:

webView.loadData(pdfDownload, MIMEType: "application/pdf", textEncodingName: "", baseURL: NSURL())

Answer 2

Swift 3:

self.webView.loadData(tempData!, MIMEType: "application/pdf", textEncodingName: "UTF-8", baseURL: NSURL() as URL)

Answer 3

The default character encoding is UTF-8 so you can do in this way:

self.webView.loadData(tempData!, MIMEType: "application/pdf", textEncodingName: "UTF-8", baseURL: NSURL())
