The buttonStyle() modifier tells SwiftUI we would like this button to get noticed, this means you’ll see it surface inside of a blue rectangle with white textual content.

To get started, you’ll must obtain Xcode with the Mac Application Store. It’s totally free, and includes Swift and all the opposite equipment you'll want to observe this tutorial.

We are able to go with a random ingredient in the array by calling the helpfully named randomElement() system on it, so replace the comment using this:

instead of having to edit the code each time, so we’re about to increase a button below our inner VStack which will modify the selected action whenever it’s pressed.
