xcode 9 crashes 100% of the time while opening a storyboard created by xcode 8 on high sierra. This happens on every project.
Error message was : "There can only be one document registered with a given URL"

Create a new single view application, open the storyboard there, and then go back to your original project and it should work.

Now you should be able to open your storyboards again
