title: Springboard Quit Unexpectedly for Empty Swift Project
body: <p>I created a new swift project, and changed nothing to the project. It is just an empty swift project. If I choose to run on iPhone 6, the springboard will crash. But if I choose others (like iPhone 5s or resizeable iPhone, even iPhone 6 Plus), the empty project works fine. </p>
  
  <p>Does anyone know what's wrong with my xcode? And how should I deal with this problem?</p>
  
  <p>The error message was so long that I cannot attach the whole message here. I'll choose some part that seems important to me. </p>
