Chapter 3. The To-do List
In this chapter, we will be building a simple, yet useful application to manage To-do items. This application will allow us to create tasks, mark them as completed, and will also provide us with the possibility to delete all the completed items by pressing a single button.
Another aspect covered in this chapter is the use of the SQLite-embedded database. Persisting all our items in such a database will allow our tasks to exist on the device even after the application is closed.
By the end of this chapter, you will have learned the following concepts:
- Creating a database structure
- Adding records to a database
- Listing all the items from a database
- Updating an existing item from a database
- Navigating through the data structure of a
TableViewcomponent - Deleting items from a database based on a filter
