UIImage sometimes flipped

I am storing images in an SQLite database as base64Strings and using the following to decode the images again:

let dataDecoded = Data(base64Encoded: imageString, options: .ignoreUnknownCharacters)
let decodedImage:UIImage = UIImage(data: dataDecoded!)!

imageView.image = decodedImage

For some images, this works, but others are shown flipped vertically. Can anyone see a reason why it only works for some?

TIA

EDIT: How the image was encoded:

let imageEncoding = userImage.pngData()!.base64EncodedString(options: .lineLength64Characters)

For images, I just used the default ones in the simulator

@matt hopefully the update helps – Ben Dent Mar 22 '20 at 22:14
Are you sometimes encoding images from your assets? – Sulthan Mar 22 '20 at 22:16
@Sulthan what do you mean by that? – Ben Dent Mar 22 '20 at 22:24
@matt I'm not sure how to access where the default simulator images are saved – Ben Dent Mar 22 '20 at 22:37
@matt `userImage = imageView.image!` after an image has been selected by the user. I'm not sure what other details there are to give, seeing as I do not know where the images provided in the default photo library in the simulator are stored – Ben Dent Mar 22 '20 at 23:04
