I’m working on webView and there is a challenging part for me capture the full screen depending on webView content.File exported successfully but not capture the whole screen data. Webview screen contains the large data like scrollable content.Can any one guide me how I can export full screen data depending on content.See my code below.

extension WKWebView {
    
    // Call this function when WKWebView finish loading
    func exportAsPdfFromWebView() -> String {
        let pdfData = createPdfFile(printFormatter: self.viewPrintFormatter())
        return self.saveWebViewPdf(data: pdfData)
    }
    
    func createPdfFile(printFormatter: UIViewPrintFormatter) -> NSMutableData {
        let originalBounds = self.bounds
        self.bounds = CGRect(x: originalBounds.origin.x, y: bounds.origin.y, width: self.bounds.size.width, height: self.scrollView.contentSize.height)
        let pdfPageFrame = CGRect(x: 0, y: 0, width: self.bounds.size.width, height: self.scrollView.contentSize.height)
        let printPageRenderer = UIPrintPageRenderer()
        printPageRenderer.addPrintFormatter(printFormatter, startingAtPageAt: 0)
        printPageRenderer.setValue(NSValue(cgRect: UIScreen.main.bounds), forKey: "paperRect")
        printPageRenderer.setValue(NSValue(cgRect: pdfPageFrame), forKey: "printableRect")
        self.bounds = originalBounds
        return printPageRenderer.generatePdfData()
    }
    
    // Save pdf file in document directory
    func saveWebViewPdf(data: NSMutableData) -> String {
        let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
        let docDirectoryPath = paths[0]
        let pdfPath = docDirectoryPath.appendingPathComponent("\(UUID().uuidString).pdf")
        if data.write(to: pdfPath, atomically: true) {
            return pdfPath.path
        } else {
            return ""
        }
    }
}

extension UIPrintPageRenderer {
    
    func generatePdfData() -> NSMutableData {
        let pdfData = NSMutableData()
        UIGraphicsBeginPDFContextToData(pdfData, self.paperRect, nil)
        self.prepare(forDrawingPages: NSMakeRange(0, self.numberOfPages))
        let printRect = UIGraphicsGetPDFContextBounds()
        for pdfPage in 0 ..< self.numberOfPages {
            UIGraphicsBeginPDFPage()
            self.drawPage(at: pdfPage, in: printRect)
        }
        UIGraphicsEndPDFContext()
        return pdfData
    }
}
