        let fileName = "MyFile"
        
        savePdf(urlString: url, fileName: fileName)

    func savePdf(urlString:String, fileName:String) {
            DispatchQueue.main.async {
                let url = URL(string: urlString)
                let pdfData = try? Data.init(contentsOf: url!)
                let resourceDocPath = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)).last! as URL
                let pdfNameFromUrl = "YourAppName-\(fileName).pdf"
                let actualPath = resourceDocPath.appendingPathComponent(pdfNameFromUrl)
                do {
                    try pdfData?.write(to: actualPath, options: .atomic)
                    print("pdf successfully saved!")
    //file is downloaded in app data container, I can find file from x code > devices > MyApp > download Container >This container has the file
                } catch {
                    print("Pdf could not be saved")
                }
            }
        }
