Comparing contents within UIImage to user input

How can I go about comparing the contents of a UIImage to the users input from a UITextField? Please assume the UIImageView is already assigned an image.

Also, are there any suggestions to the below code?

@IBOutlet var CelebrityPic: UIImageView!
@IBOutlet var YouIsRight: UIImageView!
@IBOutlet var TotalPoints: UILabel!
@IBOutlet var nextBTNOUT: UIButton!



@IBAction func responseAction(EnterHere: UITextField) { //If image is equal to user input
    if (CelebrityPic == "\(EnterHere.text)"){
        YouIsRight.image = UIImage(named: "Correct")
        YouIsRight.hidden = false
        counterNumber += 100
        TotalPoints.text = "Total points: \(counterNumber)"
        nextBTNOUT.hidden = false
        }
    if (CelebrityPic != "\(EnterHere.text)"){  //If image is not equal to user input
        YouIsRight.image = UIImage(named: "Incorrect")
        YouIsRight.hidden = false
        counterNumber -= 100
        TotalPoints.text = "Total points: \(counterNumber)"
        nextBTNOUT.hidden = false

        }
    }
