Answer 1

In one of my projects, I used this way.

  if let pdfPage = PDFPage(image: image) {

     let page = CGRect(x: 0, y: 0, width: 595.2, height: 841.8) // A4, 72 dpi
     pdfPage.setBounds(page, for: PDFDisplayBox.artBox)

     let pdfDoc = PDFDocument()
     pdfDoc.insert(pdfPage, at: 0)
     // Some code to save the doc...
  }
