title: Xcode Error: Command failed due to signal: Segmentation fault: 11
body: <p>I am getting an error "Command failed due to signal: Segmentation fault: 11" at runtime.  I believe this is a compile error because when I clean my code it does not have any errors, only when I run &amp; build.  I am using the new Xcode beta 7.1.  I also built it through my Xcode 7.0 but received same error.</p>
  
  <p>The Swift code has previously built with no errors.  This code is dealing with a Parse backend and querying some info to display to a user; here is the logs below:</p>
