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

I had this same issue when I had upgraded to Mojave and then installed an older Xcode (10.1) version. To fix I deleted all Xcode (10.2/10.1) versions and then installed Xcode 10 and it fixed the issue.
