title: User input in Xcode Playground
body: <p>I'm new to Swift and Xcode. I couldn't figure out how to take user input in Swift playground. I'm trying to write Swift equivalent of the following Python code:</p>
  
  <pre><code>def greet():
    name = raw_input('What is your name?&gt;')
    print "Hello ", name
  </code></pre>
  
  <p>Is it possible to get user input in Swift playground?</p>
