Lesson 8 - Creating an iOS ToDo app storing data
In the previous lesson, When a single screen isn't enough - Navigation in iOS, we learned several ways to navigate through multiple screens.
We'll use navigation today, since we're going to start programming a simple ToDo app. We'll show how to store data with this app. The user will be able to add tasks, mark them as completed or delete them. The data will, of course, remain saved after closing the app.
You can use the project we started in the
lesson or just create a new one (Single View App, again) for practice. You
should have a basic app ready with
TableView displaying data. The
data is, in our case, a string array, i.e. the individual tasks. Deleting items
TableView should work as well.
We'll add a second View Controller for adding new tasks. That also means
In our ToDo app, we can't mark the tasks as completed and also, if we close the app, we lose the data. We'll fix these in the next lesson, iOS ToDo app in Swift - Filling in and serialization .
