This will show the view and live update as you change the code. If you don’t see it, enable it by selecting Editor ▸ Canvas. If you’re running on macOS Catalina, you have access to the Canvas in the editor pane. This will be the first thing you’ll add and animate. Tapping the moon button will show or hide it. Later in this tutorial, you’ll put the optional MoonList in the VStack. The purpose of this button is to show information about the moons. Each element in the list is an HStack with several controls: an Image for the planet’s picture, a Text for the planet’s name, a Spacer and finally a Button, if the planet has any moons. It is a List that makes a table from the array of Planets. From there, tapping a moon will provide additional information about the planet to the user.ĬontentView represents the main screen of the app.

Once completed, tapping a row will show each planet with a list of that planet’s largest moons. The tutorial app, MySolarSystem, is a simple inventory of the planets in your solar system (assuming you’re reading this on Earth). Use the Download Materials button at the top or bottom of this tutorial to download the projects for this tutorial. If you’re just getting started with SwiftUI, check out this tutorial first. You should be comfortable with components such as Text, Image, HStack and VStack. This tutorial assumes a working knowledge of SwiftUI.

In fact, this technique is still handy on Catalina, as the preview window can be buggy.

However, if you still have Mojave, that’s fine too you can just build and run to see how code changes affect the app. You’ll have an easier time if you’re running macOS Catalina, because Xcode will show the code and live preview side-by-side in the Canvas pane. It’s best to use Xcode 11.2.1 or later, which contains fixes for known animation bugs in the SwiftUI code.
