Ios – Open PDF file using swift

How can I add a PDF file for an app , where you click on a button to view the file & when you're done you get back to screen you were at?

If you simply want to view a PDF file you can load it into a UIWebView. 

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

Swift 4.1 :

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

If you'd like to achieve more, a good framework is PSPDFKit.
