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?

Answer 1

Check out PDFKit from IOS11

Here is an example of a view controller which implements PDFView from PDFKit.

import UIKit
import PDFKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Add PDFView to view controller.
        let pdfView = PDFView(frame: self.view.bounds)
        self.view.addSubview(pdfView)

        // Fit content in PDFView.
        pdfView.autoScales = true

        // Load Sample.pdf file.
        let fileURL = Bundle.main.url(forResource: "Sample", withExtension: "pdf")
        pdfView.document = PDFDocument(url: fileURL!)
    }

}
