In this project we’re going to build a multi-screen app for ordering cupcakes. This will use a couple of forms, which are old news for you, but you’re also going to learn how to make classes conform to
Codable when they have
@Published properties, how to send and receive the order data from the internet, how to validate forms, and more.
As we continue to dig deeper and deeper into
Codable, I hope you’ll continue to be impressed by how flexible and safe it is. In particular, I’d like you to keep in mind how very different it is from the much older
UserDefaults API – it’s so nice not having to worry about typing strings exactly correctly!
Anyway, we have lots to get through so let’s get started: create a new iOS app using the App template, and name it CupcakeCorner. If you haven’t already downloaded the project files for this book, please fetch them now: https://github.com/twostraws/HackingWithSwift
As always we’re going to start with the new techniques you’ll need for the project…
SPONSORED In-app subscriptions are a pain to implement, hard to test, and full of edge cases. RevenueCat makes it straightforward and reliable so you can get back to building your app. Oh, and it's free if your app makes less than $10k/mo.
