Use the NYTimes Best Sellers Books API to load a list of best selling books in a collection view. The user should be able to select different categories to view its best selling books. Selecting a book should segue to a detail view controller where the user can see more information about the book and favorite the book. Favoriting a book should save it to the user's phone. The user should be able to view all the books that they have favorited. Favorites should persist between launches. The user should be able to use a Settings page to set the default category that will be loaded in the list of recent best sellers.

Your app should have (3) tabs

1. Best Sellers
2. Favorites
3. Settings

This view should have a:

• Collection View
• Picker View

The picker view should list all the available categories (Endpoint 1). Selecting a row in the picker view should load the appropriate images in the collection view. If the user has set a default category in the Settings tab, the picker view should spin there.

The collection view cell should include:

• The image of the books cover
• The number of weeks it has been on the best seller list
• It's short description

Selecting a cell should segue to a Detail View Controller with more information including:

• The cover
• The subtitle (if applicable)
• A long description

This view should have a:

• Collection View

The collection view should display all of the books that the user has favorited. This cell can simply be the cover of the book. Favorites should be saved to the File Manager and should persist between launches.

This view should have a:

• Picker View

The user should use this picker view to set the default category for loading books. If there is already a default set, this picker view should spin to that category. The default category should be saved using UserDefaults and should persist between launches.
