change path for exported pdf

Question

I have found this code over the internet for exporting the view to PDF. But the downloaded file stores in the library which will be hard to locate. How can I change the path, so that when I use the app on my iPhone, it gets stored in the download folder. Also, the pdf looks like it is a screenshot of the view, is there any way I can control the view to crop such as I don't want the navigation bar and other button to appear on the screen. Is there any way I can make it look like a document rather than a screenshot. Or may be resize the view to the point where I want. Or does anyone have a better code to export the file to PDF?

  func exportToPDF() {
        let outputFileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!.appendingPathComponent("SwiftUI.pdf")
        let pageSize = CGSize(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)
        let rootVC = UIApplication.shared.windows.first?.rootViewController

        //Render the PDF
        let pdfRenderer = UIGraphicsPDFRenderer(bounds: CGRect(origin: .zero, size: pageSize))
        DispatchQueue.main.async {
            do {
                try pdfRenderer.writePDF(to: outputFileURL, withActions: { (context) in
                    context.beginPage()
                    rootVC?.view.layer.render(in: context.cgContext)
                })
                print("wrote file to: \(outputFileURL.path)")
                
            } catch {
                print("Could not create PDF file: \(error.localizedDescription)")
            }
        }
    }
