I got this message when running the app:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<examSelf 0x6854ea0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key examQBodyTextView.'
The funny thing is I removed all of the related things with "examQBodyTextView" from the code since they are not needed anymore.
Note: I'm using storyboards.
