I didn't think groups would be appropriate because the same item could be in multiple groups. I think most people think of groups as containers and having the same item in multiple groups is confusing, but they do understand that a single item can have multiple tags.

The tags are for your own use. They can be for meals, ingredients, isles, pets, etc. I would not impose a "use case" for them upon the user.

There is a swipe delete, its just not shown in the movie. I'm not sure why you say its not there. It would also not be used very often so its not a big deal.
