How can I fix an error in Xcode that shows an unknown class in Interface Builder

Question

I try to compile my project and I got the following error:

2021-02-05 14:33:32.012929-0300 testeNovaView[3811:50182] [Storyboard] Unknown class _TtC13testeNovaView9VIewFile2 in Interface Builder file.

I try to open the storyboard file as a source code, but I can't find any reference from the class _TtC13testeNovaView9VIewFile2.

Where is that reference?

Answer 1

I find the problem.

I deleted the class some time ago, but didn't remove from the ViewController before remove the file.

I created the file again attach to the view Controller.

After that I remove the file from the view Controller, I create another file and put it in the viewController.

The error has gone now.
