title: Renaming a class in retrospect?
body: <p>To be on the safe side, and as my project is relatively small, when I wanted to change the name of a class in Swift, I changed it manually and went through the files individually - storyboard, class file, and in project navigator.</p>
  
  <p>In Xcode, is there another way to do this to be sure of replacing all instances, or is manually the only way to go? Can you safely use a find and replace for this purpose?</p>
