I use a func textFieldShouldReturn that depending on what Integer I have in the textField it will either display an x or a check. I have 3 textFields but the func only works for numAnswerOne. How do I make it work for all 3 textFields?

Code Block func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    //makes a return key work
    textField.resignFirstResponder()
    let text = textField.text
    let numAnswerOne = Int(answerOne.text!)
    let numAnswerTwo = Int(answerTwo.text!)
    let numAnswerThree = Double(answerThree.text!)
     
    if numAnswerOne == 70 {
      checkOne.alpha = 1
      wrongOne.alpha = 0
      answerOne.isUserInteractionEnabled = false
    } else if numAnswerOne != 70 {
      wrongOne.alpha = 1   //function stops here
    } else if numAnswerTwo == 2 {
      checkTwo.alpha = 1
      wrongTwo.alpha = 0
      answerTwo.isUserInteractionEnabled = false
    } else if numAnswerTwo != 2 {
      wrongTwo.alpha = 1
    } else if numAnswerThree == 30.1 {
      checkThree.alpha = 1
      checkThree.alpha = 0
      checkThree.isUserInteractionEnabled = false
    } else if numAnswerThree != 30.1 {
      checkThree.alpha = 0
    }
    return true
  }

Please show what your code is exactly now.

Are you sure you have defined the tags in Interface Builder as 1, 2, 3, to match the code ?
May be you just forgot to set it for numAnswerThree.

To understand what's going on, add a print after each test, such as:

Code Block if textField.tag == 1 {
	print("numAnswerOne")
	// continue

If that works, don't forget to mark the correct answer.
If not, please report with the print results.

it will either display an x or a check

Where is it in code ?

In the textFieldShouldReturn func, you should test which textField it is and act accordingly.

The problem is that the first 2 tests cover everything:

Code Block if numAnswerOne == 70 {
	checkOne.alpha = 1
	wrongOne.alpha = 0
	answerOne.isUserInteractionEnabled = false
} else if numAnswerOne != 70 {
	wrongOne.alpha = 1	 //function stops here

Whatever the value of numberOne, it will be covered by these 2, so function stops here.

Change with:

Code Block if textField == numAnswerOne {
    if numAnswerOne == 70 {
      checkOne.alpha = 1
      wrongOne.alpha = 0
      answerOne.isUserInteractionEnabled = false
    } else if numAnswerOne != 70 {
      wrongOne.alpha = 1   //function stops here
	}
}
if textField == numAnswerTwo {
	if numAnswerTwo == 2 {
      checkTwo.alpha = 1
      wrongTwo.alpha = 0
      answerTwo.isUserInteractionEnabled = false
    } else if numAnswerTwo != 2 {
      wrongTwo.alpha = 1
	}
}
if textField == numAnswerThree {
	if numAnswerThree == 30.1 {
      checkThree.alpha = 1
      checkThree.alpha = 0
      checkThree.isUserInteractionEnabled = false
    } else if numAnswerThree != 30.1 {
      checkThree.alpha = 0
	}
}

I have to convert it my textFields to NSObjects and it does not work in the end. The check marks are the check followed by a number and the xs are wrong followed by a number.

Sorry, what you explain is incomprehensible.

You started by saying that it was only working with the first textField.

With the change I proposed, does it work for all ?
If you have a problem with

Code Block if textField == numAnswerOne

then just set the tags of each textField to 1, 2 and 3
then test

Code Block if textField.tag == 1
