I've encountered this problem on Xcode 6 Beta 6. When I select the main storyboard view where I can see all the views of my app with all the components (buttons, lists etc.) I can only see the view itself but no components in them event though I have put them there before. When I build and run the app in the simulator all the components are visible, but when I develop I cannot see them. On the left side of the user interface view of main storyboard all the controllers are listed, and when I expand each of them I can see the components that should be displayed on the view but they are like disabled (faded out).
The compiler does not show any errors or warnings. Does anyone have a clue of what's going on and how I can fix this?
EDIT: I have now installed the latest version but I still have the same problem. Has no-one ever had this problem?
