Im running Xcode 9.2. My storyboards are completely useless now. Ive experienced what this article shows and have tried everything the article suggested.
My issue occurred when I tried to add a single swift file to an existing objective C project with about 320 files in it already. I removed the .swift file entirely from the project, then did everything in the article link above and still nothing fixed it including removing/reloading XCode several times trying different things.
I filed a bug with apple but haven't received any replies in a week (of course). Apple seems to be slammed with tons of bugs lately they keep creating.
Now I cannot work on this project's storyboards at all and Im dead in the water. Really not happy with Apple lately!
Is there anything more that anyone has had success in fixing this issue?
Im completely dead in the water on this application now.
