Ambiguous use of operator '!='?

Question

I am trying to create an if else statement. If the randomNumber equals the text of a label, then I want to add 1 to the CorrectLabel. If they do not equal each other than I want to add 1 to the IncorrectLabel. Here is my code:

@IBAction func checkButton(sender: UIButton) {

    if ( "\(randomImageGeneratorNumber)" == "\(currentCountLabel.text)"){
        currectAmountCorrect += 1
        CorrectLabel.text = "\(currectAmountCorrect)"

    }else if ("\(randomImageGeneratorNumber)" != "\(currentCountLabel.text)"){
        currentAmountIncorrect += 1
        IncorrectLabel.text = "\(currentAmountIncorrect)"
    }
}

I am getting an error on the "else if" statement line saying "Ambiguous use of operator '!=' ". I am unsure of what this error means or how to fix it.

What does this error mean and how can it be fixed?

You shouldn't compare like that. Just use .toInt() to cast the labeltext to int and compare it like that:

var currentCount = currentCountLabel.text?.toInt()
if randomImageGeneratorNumber == currentCount {
    currectAmountCorrect += 1
    CorrectLabel.text = "\(currectAmountCorrect)"

} else {
    currentAmountIncorrect += 1
    IncorrectLabel.text = "\(currentAmountIncorrect)"
}

There is no need to put your value into a "".
