Just renaming the file didn't work for me. What I did was:
Delete the storyboard segue and/or outlets references
Delete outlets in file ViewController.swift and copy the content file
Delete this file (Select the option "Move to trash")
Create the file again and put the content
Connect the segue and/or outlets references again
Obs: Clean Build folder and Run
