title: Swift: print() vs println() vs NSLog()
body: <p>What's the difference between <code>print</code>, <code>NSLog</code> and <code>println</code> and when should I use each?</p>
  
  <p>For example, in Python if I wanted to print a dictionary, I'd just <code>print myDict</code>, but now I have 2 other options. How and when should I use each?</p>
