title: Threading loading images from a device to a tableView in swift
body: <p>I can't find anything online about threading loading an image from a device and scrolling smoothly through a tableview. There is one on <a href="http://www.raywenderlich.com/76341/use-nsoperation-nsoperationqueue-swift" rel="nofollow">ray wen</a> about this, but it doesn't really help me for my situation. </p>
  
  <p>Does anybody have any advice or code which would help to allow a tableview to scroll smoothly and load images from the device's temporary directory?</p>
