title: Regex not working correctly on iOS
body: <p>Can someone please explain the meaning of following regex :</p>
  
  <blockquote>
    <p>^[+]?[0-9]{0,4}[ ]?(\([0-9]{1,6}\))?[0-9 ()/-]{4,}$</p>
  </blockquote>
  
  <p>This does not allow me to validate <strong>(0049) (0)151-544/187 29 or (0049)(0)15154418729</strong></p>
  
  <p>I tried to debug and my understanding says that there is an issue with the number which has 2 open and closed brackets ().</p>
  
  <p>If I make <strong>(0049) (0)151-544/187 29 as (0049) 151-544/187 29</strong> , this works.</p>
  
  <p>Can someone please help.</p>
