"No @implementation found for the class" error in Storyboard in Swift

Question

I'm trying to create in IBOutlet in Swift using my Storyboard and assistant editor, but I'm receiving a strange error I've never seen before. Looks Objective-C-ish.

I navigated to my ViewController's Save button in my Storyboard

Then I control-click dragged the Save UIButton to Xcode's assistant editor to make the IBOutlet. I get the error "Could not insert new outlet connection: No @implementation found for the class "ClassBVC". How do I avoid this error so I can make the outlet and an action?

I noticed when I click the button with the four squares before "Manual" and the < > buttons, I can go to "Counterparts" and there's a "ClassBVC" file with the same name, but with "(Interface)" next to it. It's not the file that I need though. Even when trying to create an outlet there, I get the same error.

Did you try rebuilding your project? Are there any compile errors in that file that might be making it so Xcode doesn't understand the class declaration for ClassBVC? — paddlefish, Nov 16 '17 at 21:30
Tried rebuilding, cleaning, closing the project, reopening. No other errors. — Chewie The Chorkie, Nov 16 '17 at 21:35
After several restarts of my computer, it fixed itself somehow. — Chewie The Chorkie, Nov 17 '17 at 17:10

None of the above worked. Only a reboot fixed it for me. – eklektek Apr 19 '19 at 11:36

Try closing Xcode and opening it again.

This worked for me sadly (for Apple's sake). Thanks. – Kevin Teman Nov 23 '22 at 19:34

Creating one @IBOutlet directly in the view controller, and then creating the reference to the component in the Outlet Section in .storyboard worked for me. After that, I was able to drag the components normally to their respective view controller.
