DAY 16

Project 1, part one


Now that you’ve mastered the basics of the Swift language, it’s time to start applying your skills to some real code in our first project.

This project is a check-sharing app that calculates how to split a check based on the number of people and how much tip you want to leave. The project in itself isn’t complicated, but we’ll be taking it slow so you can see exactly how these fundamentals fit together.

In some respects going back to the basics like this will feel odd – you’ve learned about closures, optionals, and throwing functions, and now there’s a bit of a reset as we look at the basics of SwiftUI. But take hope: there’s a lot of value in being able to approach new topics with a fresh mind. As Meister Eckhart said, “be willing to be a beginner every single morning” – do that, and you’ll learn much faster.

Today is the project overview day, which is where we’ll be looking at the isolated pieces of code that you need to understand in order to build our project. Tomorrow we’ll move on to the implementation day, where you’ll put those new techniques into practice with our app.

Today you have seven topics to work through, and you’ll meet Form, NavigationStack, @State, and more.

Once you’ve made it through those topics, make sure and post your progress somewhere online – it’s such an easy way to keep yourself motivated and accountable!

Share your progress!

If you use Twitter, the button below will prepare a tweet saying you completed today, along with a celebratory graphic, the URL to this page, and the challenge hashtag. Don't worry – it won't be sent until you confirm on Twitter!
