Answer 1

Both PDFView and PDFThumbnailView are now available on iOS, as of iOS 11. Code like this should get you going:

let pdfView = PDFView()
pdfView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(pdfView)

pdfView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
pdfView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
pdfView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
pdfView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true

if let document = PDFDocument(url: pathToYourPDFDocument) {
    pdfView.document = document
}
