Disable An Interactive TextField When Clicking On Another TextField

Question

I'm trying to make it so that when I click on one textField and clear it, I can't click on another one. I have this code in my TextFieldShouldReturn function but it does not seem to work. How can I make it so that when I click on one and clear it, the other one is disabled? Tried working out a solution.

if widthPer == textField {
        heightPer.isUserInteractionEnabled = false
        widthPer.isUserInteractionEnabled = true
    } else {
        heightPer.isUserInteractionEnabled = true
        widthPer.isUserInteractionEnabled = false
    }

I used this and it fixes my issue.

  func textFieldShouldClear(_ textField: UITextField) -> Bool {
        if widthPer == textField {
            heightPer.isUserInteractionEnabled = false
            widthPer.isUserInteractionEnabled = true
        } else {
            heightPer.isUserInteractionEnabled = true
            widthPer.isUserInteractionEnabled = false
        }
        return true
    }
