Hey @kishore Apple recently added PDfKit Framework try this below link.

https://developer.apple.com/documentation/pdfkit

Here what all you need to do is Take One UIView in storyboard to display Pdf files . and in Identity Inspector set class as PDFView. Take outlet like this.

@IBOutlet weak var pdfVw: PDFView!

And use following code.

 let url = URL(fileURLWithPath: "Pass your Pdf Path here")
            if let pdfDocument = PDFDocument(url: url) {
                pdfVw.autoScales = true
                pdfVw.displayMode = .singlePageContinuous
                pdfVw.displayDirection = .vertical
                pdfVw.document = pdfDocument
