Reading an image from NSUserDefaults

I have a swift app in which I have to save an image for a profile picture. I have saved it with the NSUserDefaults code below:

defaults.setObject(UIImagePNGRepresentation(imageView.image), forKey: "ProfilePicture")

My only question now is how do I read this from a file and then apply it to an UIImageView?

Thanks.

UIImagePNGRepresentation creates an NSData version of the image. So when you extract it from user defaults, you will evidently need to turn an NSData into an image — which you can do quite simply, with UIImage(data:).

[I am also trying to resist the temptation to advise you not to put some huge blob of data like an image into NSUserDefaults - use the Application Support folder instead. But I'm not succeeding!]
