Convert UIImage to NSData and convert back to UIImage in Swift?

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?

Solution

  • UIImage(data:imageData,scale:1.0) presuming the image's scale is 1.

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

    image.pngData()
