XCode Storyboard Issue

I cant see the Labels, Button etc in the View or their constraints though the Labels and Button appears on the side of the storyboard. And when you run the program in the simulator you can see that they are there. The project from my colleague who uses XCode 6.3.1 and I am using XCode 6.3.2 and he doesn't have this issue. When he updated his to to the same version I have he had the same problem; so he went back to the previous version 6.3.1. Now the problem persisted on my device even when I removed the 6.3.2 and substitute it with 6.3.1

stackoverflow prevented me from uploading the images but I can send it by email to anyone to see the screen shots
