You'll see this turtle again later on in our demo and in this once Quest series. Here we added a description to the changeTurtleEyes function. You can also add descriptions to parameters.

To add quick help to your token use three forward slashes directly above your declaration.

These descriptions can be localized which creates a better code completion experience for users in different languages. On Mac there's a new expandable area for code completion that can include quick help for each token. On iPad you'll recognize this as the area where you can browse code completion options for your current state. There are a few key parts of the Swift Playgrounds app that have been adapted to better fit the Mac platform. First let's discuss some updates in the Swift Playgrounds user interface. After that we'll show a demo of a book that behaves differently on Mac and iPad. In this session we'd like to share some of the ways that you can customize your content, so it's a great experience on both platforms. Your users will get the same experience they've come to know and love on their iPads now customized for the Mac platform. We all know Swift Playgrounds as the app that brought Swift coding to iPad, and now, but with Mac Catalyst, the same app is available on Mac too. My name is Lizzy and I'm excited to talk about how to create awesome content for Swift Playgrounds on iPad and Mac.
