PDFKit is not working in MacOs

I am creating a PDF document with the information from the database.

For iOS I have it working completely, but for macOs I can't get it to work no matter what I try.

I now have this code:

func generateRentalPDF(_ invoiceModel: InvoiceModel, _ customerInfo: CustomerModel, _ completion: @escaping (Data?) -> Void) {
         guard let baseDocument = loadBasePDF(), let page = baseDocument.page(at: 0) else {
             completion(nil)
             return
         }

         var pageBounds = page.bounds(for: .mediaBox)
         let pdfData = NSMutableData()

         guard let dataConsumer = CGDataConsumer(data: pdfData as CFMutableData),
               let pdfContext = CGContext(consumer: dataConsumer, mediaBox: &pageBounds, nil) else {
             completion(nil)
             return
         }

         pdfContext.beginPDFPage(nil)
         if let cgPage = page.pageRef {
             pdfContext.drawPDFPage(cgPage)
         }

         // Set text attributes
         let textString = "Invoice Number: \(invoiceModel.invoiceNumber)"
         let textStyle = NSMutableParagraphStyle()
         textStyle.alignment = .left
         let textAttributes: [NSAttributedString.Key: Any] = [
             .font: NSFont.systemFont(orSize: 18),
             .foregroundColor: NSColor.black,
             .paragraphStyle: textStyle
         ]

         // Calculate text position
         let textRect = CGRect(x: 100, y: pageBounds.height - 150, width: 300, height: 50)

         // Draw the text
         pdfContext.saveGState()
         pdfContext.translateBy(x: 0, y: pageBounds.height)
         pdfContext.scaleBy(x: 1.0, y: -1.0)

         let attributedText = NSAttributedString(string: textString, attributes: textAttributes)
         attributedText.draw(in: textRect)

         pdfContext.restoreGState()

         pdfContext.endPDFPage()
         pdfContext.closePDF()

         completion(pdfData as Data)
     }

When I open the document in the app, I do see the base document. Even if I put a stroke around the text, I also see the stroke. However, the text does not appear on the screen.

What am I overlooking or what am I doing wrong?

I hope someone here has an answer for me, thank you very much in advance.
