xcode 9 crash when open storyboard

Question

XCode 9 GM Candidate 1 is currently crashing when opening a storyboard.

Answer 1

I'm getting a similar issue. In my case, I've found that it consistently crashes when opening via the file explorer, whereas opening via Open Quickly (CMD+SHIFT+O) does not cause XCode to crash.
