I was getting same issue in Xcode 10.2.1

I have open interface builder (Story board) as source code just like attached screen shot by right click on storyboard file

enter image description here

Followed below steps

  1. Updated version 3.0 to 3.5 <document type="com.apple.InterfaceBuilder3.CocoaTouch.Storyboard.XIB" version="3.0"
  2. Open storyboard as interface builder again

Its get refreshed now and I was not getting error now and view was proper also

However when I revisted the spruce code of story board the version reverted to 3.0 again.

But this worked for as refresh and resolved my problem
