cell layout is not update when we are try to set image

I have try to download image and set to image view, but cell layout is not calculated correct, but when we are try to scroll tableView then cell layout is correct.

 func setUpCellDataWithImage(indexPath : IndexPath)  {
    let imageNum = String(describing: indexPath.row)
    countryName.text = imageNum
    let url : NSString = (imageUrl + imageNum) as NSString
    if let image = getImageFromUrl(urlString: url) {
      self.imageIcon.image = image
      return
    } else {
      //Download New Image
      self.downloadImageData(url: url)
    }

  }


  func getImageFromUrl(urlString : NSString) -> UIImage?{

    if let image = imageCache.object(forKey: urlString){

      return image
    }
    return nil
  }

  func downloadImageData(url : NSString)  {
    DispatchQueue.global(qos: .background).async {
      ImageDataModel().downloadImageFromUrl(urlString: url) { image in
        //Downloaded Image
        DispatchQueue.main.async {
          self.imageIcon.image = image
          self.imageCache.setObject(image!, forKey: url)
          self.setNeedsLayout()
          self.layoutIfNeeded()
        }
      }
    }
  }
