title: Swift ios - read key=value text file into nsdictionary
body: <p>I have various text files where each line contains string-key=string-value</p>
  
  <p>I can read the file into string (or maybe an array), go over line by line and split into key/value pairs myself, however, I was wondering if I was missing some built-in or easier "swift" way of doing this (new to swift) </p>
  
  <p>I could not find this question discussed before</p>
