title: Swift: Binary search for standard array?
body: <p>I have a sorted array and want to do binary search on it.</p>
  
  <p>So I'm asking if something is already available in Swift library like sort etc.? Or is there a type independend version available?</p>
  
  <p>Of course I could write it by my own, but I like to avoid reinventing the wheel again.</p>
