Task list(like ToDo List) Xcode+Swift+UserDefault

You need to make a simple task tracker in Swift + Xcode without additional beauty, the main thing it must work and with basic descriptions (// Description of the element and what it does). 1. The task has a title and date(In future), a set of statuses (new, in progress, completed), plus a text comment - a note. The application should display a list of tasks. You can view, add, delete and edit tasks. And also filter tasks by their status. 2. Add today-extension, which displays the shortest deadline task. Add a quick transition from today-extension to viewing task information in the main viewController. 3. The ability to set a task by fumbling into the application from outside a piece of text. To store the data will be enough UserDefaults, but you can add any libraries, if necessary. But it is better without additional libraries. The main thing so I can understand where everything is going and how it works.
