Custom Codable Keys #When our JSON data matches the types we design, Codable works perfectly. In fact, it’s usually enough that we don’t do anything more than add the Codable compatibility - the Swift compiler will automatically generate everything we need.

While this is just an introduction to what SwiftData can do, you’ve seen how it can add, delete, sort, filter and more with relatively simple code.

Today we will work on topics such as NSPredicate, dynamically changing fetch requtes, creating relationships. The topics we will work on today;

In our last project we looked at using SwiftData with SwiftUI, in this project we’ll go into more detail: we’ll look at things like custom managed object subclasses and ensuring uniqueness.

Congratulations on finishing another SwiftUI project! With technologies like SwiftData on your side, you can now build some serious apps that interact with the user and most importantly remember what they input.

Today we will learn how to delete SwiftData objects, how to sort queries using SortDescriptor and how to add custom buttons to alerts.

We will start applying the new techniques we have learned to create our application. We’ll use SwiftData to create a book object and a custom RatingView component created using @Binding for users to record how much they liked each book.

Today we’re starting a new project and this is where things start to get really serious because we’re going to learn an important new Swift skill that will come in handy as you build the project.

Hopefully this project has shown you how to use the skills you already know (SwiftUI Picker, Stepper and Navigation) and turn them into an app that sends all the user’s data to a server and processes the response.

In this section we will see how to send and receive data over the internet using URLSession.
