Open PDF File Using Swift

Open PDF file using swift

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.

how to view pdf files in collectionview?

You can try to implement the PDFKit framework in your app. This framework has been available since IOS 11.

Create an extra class in you project called "PDFView" and assign the CollectionViewCell (in which you are trying to display the PDF) to this class. Then you can setup the loading of the PDF file in your newly created "PDFView" class.

For more information over the implementation please see this question.
