title: Xcode 7: ignore .xcscmblueprint in repository?
body: <p>I noticed that Xcode 7 creates a new <code>.xcscmblueprint</code> file in the <code>xcshareddata</code> folder. Will it be always auto generated? Should this file be added to the ignore list of the repository, or should it be checked in into repository? </p>
  
  <p>Xcode 6 has the <code>.xccheckout</code> file, I've always gitignore'd that file.</p>
