Circular UIImage from FBSDK xcode swift - ios

Question

I have a profile picture which I am taking from a URL from facebook graph request that I am trying to make into a circular profile picture but it is appearing like this:
I don't want it to be pointing at the top, I just want a perfect circle.
This is my code:
#IBOutlet var imageURL: UIImageView!
func returnUserData()
{
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,email,name,picture.width(50).height(50)"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print("fetched user: \(result)")
let userID : NSString = result.valueForKey("id") as! NSString
let userName : NSString = result.valueForKey("name") as! NSString
print("User Name is: \(userName)")
let userEmail : NSString = result.valueForKey("email") as! NSString
print("User Email is: \(userEmail)")
let facebookProfileUrl = "https://graph.facebook.com/\(userID)/picture?type=large"
print("\(facebookProfileUrl)")
let url = NSURL(string:facebookProfileUrl)
let data = NSData(contentsOfURL:url!)
if data == nil {
} else {
self.imageURL.layer.borderWidth=1.0
self.imageURL.layer.masksToBounds = false
self.imageURL.layer.borderColor = UIColor.whiteColor().CGColor
self.imageURL.layer.cornerRadius = 15
self.imageURL.layer.cornerRadius = self.imageURL.frame.size.height/2
self.imageURL.clipsToBounds = true
self.imageURL.image = UIImage(data:data!)
}
}
})
}

Apparently your input image isn't square. Crop the top and bottom (or extend the sides) to make it square, then the rest should work.
