   I have created a solution for this problem by adding empty images

   // first get real data from image array and convert it to PDFImage

    var pdfImagesArr = [PDFImage]()
           for data in otherImageArr{
               let imageData = data["image"] as? Data ?? Data()
               let text = data["name"] as? String ?? ""
               let fetchImage = UIImage(data: imageData) ?? UIImage()
               let otherImage = PDFImage(image: fetchImage.resized(withPercentage: 0.4) ?? UIImage(),caption: PDFAttributedText(text: NSAttributedString(string: text == "" ? " " : text ,attributes: captionAttributes)), quality: 1.0, options: .none)
               pdfImagesArr.append(otherImage)
           }
   

   // once we get converted PDFImage array, we will add empty images to get 3 images per row like we have 1 image to show we need to add +2 empty images

           if pdfImagesArr.count % 3 != 0{
               var result = 0
               var diffCellCount = 0
               result = pdfImagesArr.count % 3
               if result != 0{
                   diffCellCount = 3 - result
                   for _ in 0..<diffCellCount{
                       let otherImage = PDFImage(image: UIImage(named: "Empty") ?? UIImage(),caption: PDFAttributedText(text: NSAttributedString(string: "",attributes: captionAttributes)))
                       pdfImagesArr.append(otherImage)
                   }
               }
           }
   

   // setting 3 images per row

           var threeImages = [PDFImage]()
           for data in pdfImagesArr{
               threeImages.append(data)
               if threeImages.count == 3{
                   document.add(imagesInRow: threeImages, spacing: 10)
                   document.add(space: 20)
                   threeImages.removeAll()
               }
           }
