title: Swift: Remove specific characters of a string only at the beginning
body: <p>i was looking for an answer but haven't found one yet, so:</p>
  
  <p>For example: i have a string like "#blablub" and i want to remove the # at the beginning, i can just simply remove the first char. But, if i have a string with "#####bla#blub" and i only want to remove all # only at the beginning of the first string, i have no idea how to solve that.</p>
  
  <p>My goal is to get a string like this "bla#blub", otherwise it would be to easy with replaceOccourencies...</p>
  
  <p>I hope you can help.</p>
