title: Remove all line breaks at the beginning of a string in Swift
body: <p>I have a string like this:</p>
  
  <pre><code>"
  
  BLA
  Blub"
  </code></pre>
  
  <p>Now I would like to remove all leading line breaks. (But only the ones until the first "real word" appears. How is this possible?</p>
  
  <p>Thanks</p>
