Using searchable lists with scopes

In this recipe, we will improve our searchable list with the addition of the searchScopes(_:activation:_:) modifier, which allows us to narrow the scope of our searches.The scope modifier could be useful to further reduce the scope of our search and reduce the time it takes to find an item. In our case, we have a list of food items, belonging to three different categories: meat, fruit, and vegetables. Selecting a specific scope narrows the search and gives the user a quicker way of finding the desired item.

However, Apple also releases new features during the year as is the case for the one we are using in this recipe.
