title: Signal sigabrt when adding a view
body: <p>Just when starting on different projects on Xcode (Single view, Master-detail,...)
  I meet always the thread 1 : Signal sigabrt warning which stops my iOS simulator.</p>
  
  <p>For this simulation, I start from a single view project with one button linked to another single view. Nothing complicated, even if I'm new in iOS dev world.</p>
  
  <p>Thanks for helping me</p>
