 In this tutorial you’re going to use Swift and SwiftUI to build a small app to recommend fun new activities to users. Along the way you’ll meet several of the basic components of a SwiftUI app, including text, images, buttons, shapes, stacks, and program state.
 
 To get started, you’ll need to [download Xcode from the Mac App Store](https://apps.apple.com/app/xcode/id497799835?mt=12). It’s free, and comes with Swift and all the other tools you need to follow this tutorial.

 If you’d like to continue learning SwiftUI, there are lots of free resources available. For example, [Apple publishes a wide variety of tutorials](https://developer.apple.com/tutorials/swiftui) covering essential topics, drawing and animation, app design, and more. We’ll also post links here on Swift.org to some other popular tutorials – we’re a big and welcoming community, and we’re glad to have you join!
