title: Xcode 8 MainStoryboard showing blue rectangles instead of objects
body: <p>I have latest version of Xcode 8 official release, and Im seeing blue rectangles borders filled white, instead of normal objects(Labels, Images, etc) on the main storyboard, I Drag an Image, button or anything and it just shows a blue rectangle (I don't see the object inside the rectangle, just an empty blue bordered rectangle), I attach an image for you guys to see, Any clue on how to solve it? Someone else with the same issue? This is happening an all My projects, and just start happening suddenly.. since the first day I was having no issue with this Xcode version.</p>
