Description
So far our Quiz App looks like an app. Now we're going to make it behave like one.
In this SwiftUI lesson, you'll turn the answer labels into real Button views, connect button taps to your own Swift function, reuse logic with parameters, and introduce @State so the interface can respond when data changes.
We'll also connect some of the terminology you've already seen by looking at properties and methods inside a SwiftUI view.
By the end of this lesson, we'll be one step away from completing the first version of the Quiz App.
