I'm trying to save a UIImage to NSData and then read the NSData back to a new UIImage in Swift. To convert the UIImage to NSData I'm using the following code: 

let imageData: NSData = UIImagePNGRepresentation(myImage)

How do I convert imageData (i.e., NSData) back to a new UIImage?

In swift 4.2, use below code for get Data().

image.pngData()
