Xcode 8.1 storyboard showing blue lines only

Question

I installed Xcode 8.1 and the storyboard shows only blue lines, for all UI elements. If someone has figured it out let me know. I am unable to revert it to even Xcode 8.0.

Answer 1

Ok, So finally I too got the blue line problem in Xcode 8.1

Here is the screenshot

We can see the error message:

An internal error occurred. Editing functionality may be limited

with a Report a Bug button on the right side.

Don't know why it happened. But I just quit Xcode and Simulator and restarted it. That fixed it and I got the UI elements back.
