IOS error while using a search bar

IOS error while using a search bar

Hi in my app I've a TableView in which I show something and I want to
search in this TableView for a text I write in the search bar, so I
followed this tutorial. In my app I'm having a problem, when I run the app
and I try to search a letter it crash and in xCode I see this information:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason:
'[<__NSCFString 0x9e45990> valueForUndefinedKey:]: this class is not key
value coding-compliant for the key name.'. I checked my Storyboard to see
if I have something wrong, but it's all ok. So I guess the problem it's in
the code, I will post here my code and I hope you can help me what's
wrong.
