Restart your Mac will also help.

I solved this after looking at the answer on this question: Storyboard broken after updating Xcode to version 10.3 (10G8) & app no longer is running
Restarted the mac, problem solved.
After installing Xcode 7 I can't build and run projects anymore as document fails to open
I am not sure which answer to accept as for me what worked was installing a later beta (beta 5). I had filed a bug to Apple a couple of months ago so I assume they solved this problem by updating Xcode.
Anyone experiencing this with the current official release?
I post this as answer for now but if anyone has a more detailed explanation I will be happy to remove my answer and accept yours.
