How to use json property to create toggle and searchbar

Hi,
I try to create an app on Xcode to list all my films.
On the first view i have the list and on the second view i have options like "toggle" to indicate if film was seen and "slider" to note film.

I want to create a toggle on the list to display only the no-show films, but i do not achieve to find ten right property to use to make out functional...

You can check my project here : https://github.com/thomjlg/Films-APP

JSON file : https://gist.githubusercontent.com/thomjlg/0782e9e8e27c346af3600bff9923f294/raw/9705fb0c6b40eae59578755b86e331bea257972b/films2.json

PS : i also have the same error type for my searchbar..

Thanks for your help (i am a beginner)
