Getting Image from URL for UIView [Swift]

Question

Alright so I've made some handlers and classes to grab data from a URL, its all returning fine, I've checked the URLs are valid and everything.

Anyways, I'm trying to do an NSData(contentsOfURL) on a stored URL in my class for a UIViewController. I'm successfully printing out String Variables like name, type, description, but I'm having difficulty displaying an UIImage into a Image View on the ViewController.

Here is my Code, it's run when the View loads:

func configureView() {
        // Update the user interface for the detail item.
        if let card = detailCard {
            title = card.cardTitle

            //Assign Elements
            detailDescriptionLabel?.text = card.description
            typeLabel?.text = card.cardType
            cardTitleLabel?.text = card.cardTitle
            costLabel?.text = card.cardCost

            print(card.cardImageURL)

            if let url = NSURL(string: card.cardImageURL){
                let data = NSData(contentsOfURL: url)
                imageView.image = UIImage(data: data!)// <--- ERROR HERE: EXC_BAD_INSTRUCTION
            }

            //Print Log
            //print(card.logDescription)
        }
    }

Like the comment says above, I get the error on the imageView.image = UIImage(data: data!) line:

Thread 1: EXC_BAD_INSTRUCTION

Here is the code for cardImageURL:

var cardImageURL: String {
    return String(format: "http://testyard.example.net/display/images/cards/main/%@", image)
}
//This is a computed variable when a "Card" class object is created.

It returns the correct url in a string:

http://testyard.example.net/display/images/cards/main/armor-of-testing.jpg

I've used this code elsewhere, and it worked fine, why is it throwing errors here?

Thanks in advance.

Are you sure the data being downloaded is an image? You should probably use this line:

if let image = UIImage(data: data)`

This should stop the error, though you might need to test that your data actually contains an image.
