Although SwiftUI is described as being data driven, it is still necessary to handle the events that are generated when a user interacts with the views in the user interface. Some views, such as the Button view, are provided solely for the purpose of soliciting user interaction. In fact, the Button view can be used to turn a variety of different views into a “clickable” button. A Button view needs to be declared with the action method to be called when a click is detected together with the view to act as the button content. It is possible, for example, to designate an entire stack of views as a single button. In most cases, however, a Text view will typically be used as the Button content. In the following implementation, a Button view is used to wrap a Text view which, when clicked, will call a method named buttonPressed():
struct ContentView: View {
var body: some View {
