title: How do I setup a Unit Test for Swift?
body: <p>I feel it prudent to attempt to master Unit Testing/Swift. <br/>
  I viewed WWDC's Objective-C version and pretty much understand the Objective-C paradigm: importing the headers that the Unit Test depends on, etc.
  <p>
  The 'fetchFlickrPhotoWithSearch()' is unknown to the Unit Test.  So...
  <p>
  Being that a Unit Test module/target is outside the scope of the application target, I assume that I need to import the particular Swift file (similar to Objective-C's header paradigm) that has the functions I wish to test.
  <p>
  But the compiler flags this import as 'No such module...'
  <p>
  So... how do I make my Swift APIs <em>available</em> to the unit test?</p>
