Since iOS 11, you can use the native framework called PDFKit for displaying and manipulating PDFs.

After importing PDFKit, you should initialize a PDFView with a local or a remote URL and display it in your view.

if let url = Bundle.main.url(forResource: "example", withExtension: "pdf") {
    let pdfView = PDFView(frame: view.frame)
    pdfView.document = PDFDocument(url: url)
    view.addSubview(pdfView)
}
