Saving and retrieving images with correct order

Question

I'm trying save some images to an array, and their name to another array as string with below code;

self.countryNamesArray.append(object["CountryName"] as! String)
let image = UIImage(data:imageData!)
self.countryImages.append(image!)

But it doesn't retrieve images with same order I saved while retrieve CountryNamesArray with correct order.

rowString = countryNamesArray[row]
myImageView.image = self.countryImages[row]

Should I use custom class to save images with string or are there any way to fix?
