Download image programmatically in fast mode

Question

I have an ImageView. This is the code I use to add an image to ImageView

 var imgstr = pf["ImageFileName"] as String
 image = UIImage(named: imgstr)!
 println(imgstr) //the output here is abc.png
 self.Imageview.image = image

Now I have an image in the Project folder, as you can see in the screenshot

However, I get this error at runtime

fatal error: unexpectedly found nil while unwrapping an Optional value

Answer 1

Add your images to Images.xcassets

imageView.image = UIImage(named:"abc")

Answer 2

How about this?

if let image = UIImage(named:"abc") {
   imageView?.image = image
}

Answer 3

put

self.Imageview!.image = image

instead

self.Imageview.image = image
