you can directly get the image from imageview

  func tapImage(_tap:UITapGestureRecognizer) {

   if let getImage = tap.view as! UIImageView
    {
          viewDisplay(getImage:img)
      }

}

for sample

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self. tapImage(_:)))
imgView.isUserInteractionEnabled = true
imgView.addGestureRecognizer(tapGesture)

and handle the action as

func tapImage(_ tap: UITapGestureRecognizer) {

   if let getImage = tap.view as! UIImageView
    {
          viewDisplay(getImage:img)
      }

}

self.imgView.isUserInteractionEnabled = true
let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped))
imgView.addGestureRecognizer(tapRecognizer)


 func imageTapped(gestureRecognizer: UITapGestureRecognizer)
 {

  let tappedImageView = gestureRecognizer.view!
  let imageView = tappedImageView as! UIImageView
  print("image ---%@",imageView.image!)
 }

you need to modify your answer, if you are using like this `#selector(imageTapped))`, then you need to call the function as like `func imageTapped {` not `func imageTapped(gestureRecognizer: UITapGestureRecognizer) {` – Anbu.Karthik Mar 03 '17 at 05:33
Thanks But we can also use this – Lalit kumar Mar 03 '17 at 05:38
