Create a UIView subclass wrapper for PDFView

DocumentView.swift

// This struct will return pdfView in UIView form to make it SwiftUI compatible
struct PDFViewUI : UIViewRepresentable {

    var url: URL?
    init(url : URL) {
        self.url = url
    }

    func makeUIView(context: Context) -> UIView {
        let pdfView = PDFView()

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

        return pdfView
    }

    func updateUIView(_ uiView: UIView, context: Context) {
        // Empty
    }

}
