Few have mentioned that the problem was related to segues, mine was too, although it did not pop up immediately after i added the new segue and i was able to run the app a few times make some changes, add new views before it occurred, so don't disregard this. I went deleting some of the controllers and undoing in case it didn't help. If a segue is the issue you may build but you wont be able to add that segue, so re-create the entire view controller if it's a viable option. Copying and pasting didn't seem to work, though i did not try removing the IBOutlet connections.
