It's simple. Please use the data model for it.

func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

    switch pickerView {
    case sexPicker:
        sexText.text = sex[row] 
    case agePicker:
        ageText.text = age[row]
    case proPicker:
        professionText.text = profession[row]
    default:
        break
    }

}
