you can use webview to show pdf data like,

 [webview loadData:PdfContent MIMEType:@"application/pdf" textEncodingName:@"utf-8" baseURL:nil];

pass your data which you get from nsuserdefault in place of pdfContent.

it's objective c code convert this line in swift.

In swift something like,

func loadData(_ data: NSData,
    MIMEType MIMEType: String,
   textEncodingName textEncodingName: String,
     baseURL baseURL: NSURL)

if you want to open from url then,

let url : NSURL! = NSURL(string: "http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIWebView_Class/UIWebView_Class.pdf")
webView.loadRequest(NSURLRequest(URL: url))

hope this will help :)

Thanks. I believe this is what I need and am working on swift code now. Can you advise how to put MIMEType: String ? What string should be used here? — Mike, Apr 17 '16 at 21:39
