You can use Share Extension (UIActivityViewController) to share your pdf fileURL. Note that the user will have to select the WhatsApp application to share the file. Note is is required to edit your info.plist and add whatsapp to your LSApplicationQueriesSchemes array if you would like to check first if WhatsApp is installed:

func sharePdfWhatsApp(url: URL) {
    let whatsappURL = URL(string:"whatsapp://app")!
    // this will make sure WhatsApp it is installed
    if UIApplication.shared.canOpenURL(whatsappURL) {
        let controller = UIActivityViewController(activityItems: [url], applicationActivities: nil)
        present(controller, animated: true) {
            print("done")
        }
    }
}

First you have to retrieve your PDF file as a Data format.

var pdfDATA:Data!

Once you get data to above variable you can run below code to send PDF via WhatsApp.

self.pdfDATA = try? Data.init(contentsOf: yourFilepath)
let activitycontroller = UIActivityViewController(activityItems: [self.pdfDATA], applicationActivities: nil)
            if activitycontroller.responds(to: #selector(getter: activitycontroller.completionWithItemsHandler))
            {
                activitycontroller.completionWithItemsHandler = {(type, isCompleted, items, error) in
                    if isCompleted
                    {
                    print("completed")
                    }
            }
        }
            activitycontroller.excludedActivityTypes = [UIActivityType.airDrop]
            activitycontroller.popoverPresentationController?.sourceView = buttonItemSize
            self.present(activitycontroller, animated: true, completion: nil)
