A simple offline todo app where you can manage your tasks and set a reminder on to receive a notification built using VIP architecture. The data is persisted via CoreData.

The application consists of two screens. Both screens follow the same pattern in which there is a unidirectonal control between ViewController, Interactor, and Presenter.

1. Todo List

   The screen consists of a list of todo titles displayed in UITableView and can be searched through using UISearchBar with an additional sort button to enable sorting alphabetically in ascending or descending order.

2. Todo Detail

   This is the screen that is navigated to when the user wants to add a new todo by pressing on Add ToDo button or on an existing todo itself. This screen is used for creating, as well as editing a todo.

   It basically consists of a form made up of two UITextFields for entering the title and detail about the todo, and a UIDatePicker to set a notification time only for future dates.

Each and every todo is assigned a UUID, and must have a non-empty title. Additionally you can add detail, as well as set a date as to be reminded by receiving notification.

Here's the todo schema:

• Create (add) a new task by entering a short descriptive title.

  You can also enter additional details and set a reminder.

• Edit the task. You can edit all of the fields

• See all your tasks.

  Tasks are sorted by the time created as default, but can be further sorted alphabetically in ascending or descending order.

• Search among your tasks:

  If there is a match, then the app shows only the matches, and else, i.e., if there is no item matching your search, then all of the items are shown.

• Remove the task by swiping left.
