title: ArraySlice in Array Swift
body: <p>after using the prefix method on an Array I get what is called an arraySlice. How can I transform this into an Array?</p>
  
  <p>I am trying to fetch Ints from FacebookGraphApi then asking for the first 3 (prefix(3)) and trying to add them into a new array.</p>
  
  <p>Thank you in advance</p>
